Seasonal affective disorder (SAD), now known clinically as major depressive disorder with seasonal patterns, is a condition that causes sadness or depression when the seasons change.
It most typically occurs during the fall and winter, when days become short and exposure to sunlight decreases. It’s most common in women and young adults.
Counseling, therapy, and medication may all be effective for this condition. Light boxes — also referred to as SAD lamps or light therapy lamps — are another option that can reduce symptoms and provide relief. They work by replicating natural daylight.
Symptoms of SAD
There are two types of SAD: wintertime and summertime. SAD affects people differently, but the symptoms may vary based on the type of SAD.
Symptoms of wintertime SAD include:
- daytime fatigue
- difficulty concentrating
- feelings of hopelessness
- increased irritability
- lack of interest in social activities
- lethargy
- reduced sexual interest
- unhappiness
- weight gain
Symptoms of summertime SAD include:
- agitation
- difficulty sleeping
- increased restlessness
- lack of appetite
- weight loss
In severe cases, people with SAD may experience thoughts of suicide.
Treatment options for SAD
Counseling and therapy are treatment options for both forms of SAD. Some people may also benefit from medications such as antidepressants such as fluoxetine (Prozac) and bupropion (Wellbutrin). People experiencing SAD should speak to their doctor about which medication is the best course of treatment.
Light therapy can also be used as a treatment for wintertime SAD. This involves using a specialized light box or visor for at least 30 minutes each day to mimic natural light. Light therapy should only be used under a doctor’s supervision and on approved devices. Other light-emitting sources like tanning beds, are not safe for use.
Another type of treatment is a dawn simulator which uses a time-activated light to mimic the sunrise as a way to help stimulate the body’s clock.
Adopting some healthy lifestyle habits can also help minimize SAD symptoms. This can include:
- a balanced diet with lean protein, fruits, and vegetables
- exercise
- regular sleep
Keep in mind
If you have thoughts of suicide or self-harm, call 911 or the National Suicide Prevention Lifeline at 988.
Some research shows that light therapy can help improve seasonal depression, even with as little as 20 minutes of exposure. Although the FDA doesn’t regulate SAD lamps, Healthline’s medical affairs team still every pick and brand, diving into medical credibility, the company’s reputation, and its business practices.

A SAD lamp uses light therapy to replicate sunlight. It can trick the body into thinking it is a warmer month and cause the body to release serotonin.
The light produced by a SAD lamp is measured in lux. A lux is a measurement of light intensity combined with area. A SAD lamp should offer a brightness of 10,000 lux. The viewing angle of a lamp should allow it to be positioned above the eyes and at a slight downward angle to minimize glare.
Typically, SAD lamps or lights should be used for 30 minutes to an hour. They can be used at any time of day, although they’re usually used first thing in the morning.
SAD lamps are not regulated by the FDA.
SAD lamps simulate sunlight, which helps trigger the brain to release serotonin, often called the feel-good hormone.
Studies show that using light therapy during periods when daylight hours are short can help adjust your circadian rhythm, the body’s process for regulating your sleep-wake cycle. This is beneficial for improving mood and reducing symptoms of depression.
Light therapy has become an accepted practice for alleviating SAD and other conditions such as:
- jet lag
- dementia
- circadian rhythm sleep disorders
There are many lamps and light boxes marketed as SAD or light therapy lamps. Not all of these products are effective or appropriate for this use.
The FDA doesn’t regulate SAD lamps, so it’s important to buy one that provides enough light and is designed to treat SAD.
Here are some features to look for:
Safety
- Don’t get a light box that’s designed to treat skin conditions. These devices aren’t meant to treat mood disorders and they won’t be effective.
- Make sure the lamp filters out ultraviolet (UV) light and is labeled UV-free. UV light can damage your eyes and skin.
- Follow the instructions supplied by the manufacturers.
- Use eye protection if you have existing eye issues.
Specs
- The lamp should generate 10,000 lux of cool-white, fluorescent light. An output of 10,000 lux is approximately 20 times greater than the light output generated by most indoor lighting. Lamps with less lux may need to be used more often than brighter ones.
- Opt for a glare-free lamp or a lamp that can be positioned at a downward angle that reduces or eliminates eye glare.
Size
- Look for a lamp with a light surface area of around 12 by 15 inches. The larger the surface area, the higher the lux. Larger lamps also provide you with the option of moving around more, so you can be farther away from the lamp without compromising its effectiveness.
- Smaller lamps aren’t as effective and may need to be used more often for longer sessions. That said, you may wish to purchase a second, smaller lamp if you travel a lot. Your doctor can provide individualized lamp use guidelines.
Personal style and needs
- Think about what activity you would like to do while using the lamp and purchase one that will accommodate that purpose. For example, light boxes have been shown to help with jet lag. So, if you travel frequently, you may want to choose a small, portable option.
- Lamp styles vary. You may be better off getting an attractive lamp that matches your décor so it can stay in position for use. For maximum benefit, you’ll want to use the lamp at least once daily, so having it out and easily accessible can be a plus.
- Don’t start using a SAD lamp without your doctor’s approval: This is especially important if you have a diagnosis such as bipolar disorder, glaucoma, or lupus.
- Always get the green light from your doctor if you’re taking prescription medications of any kind, including antipsychotics and antidepressants: Remember that some prescription medications and over-the-counter supplements can make your skin photosensitive, requiring an adjustment to your use of the lamp. These medications include lithium, some acne drugs, and St. John’s wort.
- Use the lamp daily: You can use it until daylight hours increase.
- Experiment with time frame: Many people benefit from as little as 20 minutes of use. Others require 60 minutes, which is typically considered the highest exposure you should get. However, be sure to follow the manufacturer’s instructions and slowly increase the amount of time spent in front of a SAD lamp. Avoid exceeding more than 60 minutes of use.
- Consider when to use it: Many experts recommend using a SAD lamp first thing in the morning. Your doctor might also recommend that you use it during the day. Keep in mind that more isn’t always better. Overuse of a SAD lamp can produce insomnia or other side effects.
- Follow manufacturer recommendations for the position: Your lamp should come with recommendations for how close you should position yourself to it. This is very important, as your distance from it will affect the lamp’s lux capacity.
- Position the lamp so that it’s providing you with downward light: This will ensure that it doesn’t shine directly into your eyes.
- Talk with your doctor about how to best stop using the lamp: It may be most appropriate for you to wean yourself off slowly. Spending time outdoors, especially in the mornings, can help this process.
Although light therapy is helpful for people who bipolar disorder, be sure to consult with a doctor before introducing it daily. A medical professional who is familiar with your physical and mental health history will be able to help you figure out if light therapy is a good option for you.
Some studies show that SAD lamps can help boost mood and alleviate symptoms of seasonal depression, but they’re not a substitute for proper mental health care. If you feel that your depression is severe or you experience any of the following symptoms, it’s time to speak with a healthcare professional. Check in with a doctor or mental health professional if:
- You feel sad and hopeless nearly every day.
- You no longer experience pleasure in hobbies or activities you used to enjoy.
- You can’t sleep or are spending too much time sleeping.
- You’re feeling irritated and annoyed nearly every day.
- Symptoms are interfering with your quality of life.
- You’re gaining or losing weight unexpectedly.
Can SAD lamps damage your skin or eyes?
UV light should be filtered out of SAD lamps, so they shouldn’t damage your eyes or skin. However, light boxes used to treat certain skin conditions do emit UV light, so you should be sure that your light box is designed to treat SAD.
Can SAD lamps increase vitamin D levels?
While some people have found that SAD lamps can increase vitamin D levels over time, there’s not enough research to confirm this. Vitamin D is produced by UV light, and most SAD lamps don’t have that.
According to the FDA, UV lights can cause damage to the skin and should be used with caution. Long-term exposure to UV rays can also cause premature aging and skin cancer. If you’re using UV lights on your skin, be sure to speak with your doctor first.
How bright are SAD lamps?
The recommended brightness for SAD lamps is typically 10,000 lux.
How long does it take a SAD lamp to start working?
The University of British Columbia found that people can start to respond to light therapy within a few days and you should see improvements within 2 weeks. Be sure to speak to your doctor if your body does not respond to a SAD lamp after 2 weeks.
Is there anyone who shouldn’t use a SAD lamp?
You should avoid using a SAD lamp if you have an increased sensitivity to light. This may be due to:
- macular degeneration
- a connective tissue disorder
- lupus

SAD can often be alleviated with proactive lifestyle changes. These include:
- going to bed early and waking up at or near dawn
- going outside for extended periods of time, especially first thing in the morning
- avoiding substances that can adversely affect your ability to sleep, such as alcohol
- eating whole, nutrient-rich foods
- exercising
- seeking out professional help from a counselor or therapist
How to find a therapist for seasonal affective disorder
SAD can bring up serious feelings of depression, so consider talking with a mental health professional.
You don’t need to have received a SAD diagnosis to seek out help, though. Even if you’re just feeling more down than usual, it’s OK to talk with a therapist or counselor.
When looking for a mental health professional, you’ll want to specifically search for someone who has experience treating SAD, major depressive disorder, or depressive episodes.
If leaving the house is too intimidating, you can check out online therapy or online psychiatry platforms, too.
Major depressive disorder with seasonal pattern, previously known as seasonal affective disorder (SAD), is a condition caused by lowered exposure to sunlight or a change of seasons. Women and young adults are most affected by this condition.
Using a SAD lamp, also known as a light box, can help alleviate symptoms, boosting your mood.
SAD lamps can be effective when used as a solo treatment or combined with other forms of treatment. Either way, always use these lamps under a doctor’s supervision.

A SAD lamp uses light therapy to replicate sunlight. It can trick the body into thinking it is a warmer month and cause the body to release serotonin.
The light produced by a SAD lamp is measured in lux. A lux is a measurement of light intensity combined with area. A SAD lamp should offer a brightness of 10,000 lux. The viewing angle of a lamp should allow it to be positioned above the eyes and at a slight downward angle to minimize glare.
Typically, SAD lamps or lights should be used for 30 minutes to an hour. They can be used at any time of day, although they’re usually used first thing in the morning.
SAD lamps are not regulated by the FDA.
SAD lamps simulate sunlight, which helps trigger the brain to release serotonin, often called the feel-good hormone.
Studies show that using light therapy during periods when daylight hours are short can help adjust your circadian rhythm, the body’s process for regulating your sleep-wake cycle. This is beneficial for improving mood and reducing symptoms of depression.
Light therapy has become an accepted practice for alleviating SAD and other conditions such as:
- jet lag
- dementia
- circadian rhythm sleep disorders
There are many lamps and light boxes marketed as SAD or light therapy lamps. Not all of these products are effective or appropriate for this use.
The FDA doesn’t regulate SAD lamps, so it’s important to buy one that provides enough light and is designed to treat SAD.
Here are some features to look for:
Safety
- Don’t get a light box that’s designed to treat skin conditions. These devices aren’t meant to treat mood disorders and they won’t be effective.
- Make sure the lamp filters out ultraviolet (UV) light and is labeled UV-free. UV light can damage your eyes and skin.
- Follow the instructions supplied by the manufacturers.
- Use eye protection if you have existing eye issues.
Specs
- The lamp should generate 10,000 lux of cool-white, fluorescent light. An output of 10,000 lux is approximately 20 times greater than the light output generated by most indoor lighting. Lamps with less lux may need to be used more often than brighter ones.
- Opt for a glare-free lamp or a lamp that can be positioned at a downward angle that reduces or eliminates eye glare.
Size
- Look for a lamp with a light surface area of around 12 by 15 inches. The larger the surface area, the higher the lux. Larger lamps also provide you with the option of moving around more, so you can be farther away from the lamp without compromising its effectiveness.
- Smaller lamps aren’t as effective and may need to be used more often for longer sessions. That said, you may wish to purchase a second, smaller lamp if you travel a lot. Your doctor can provide individualized lamp use guidelines.
Personal style and needs
- Think about what activity you would like to do while using the lamp and purchase one that will accommodate that purpose. For example, light boxes have been shown to help with jet lag. So, if you travel frequently, you may want to choose a small, portable option.
- Lamp styles vary. You may be better off getting an attractive lamp that matches your décor so it can stay in position for use. For maximum benefit, you’ll want to use the lamp at least once daily, so having it out and easily accessible can be a plus.
- Don’t start using a SAD lamp without your doctor’s approval: This is especially important if you have a diagnosis such as bipolar disorder, glaucoma, or lupus.
- Always get the green light from your doctor if you’re taking prescription medications of any kind, including antipsychotics and antidepressants: Remember that some prescription medications and over-the-counter supplements can make your skin photosensitive, requiring an adjustment to your use of the lamp. These medications include lithium, some acne drugs, and St. John’s wort.
- Use the lamp daily: You can use it until daylight hours increase.
- Experiment with time frame: Many people benefit from as little as 20 minutes of use. Others require 60 minutes, which is typically considered the highest exposure you should get. However, be sure to follow the manufacturer’s instructions and slowly increase the amount of time spent in front of a SAD lamp. Avoid exceeding more than 60 minutes of use.
- Consider when to use it: Many experts recommend using a SAD lamp first thing in the morning. Your doctor might also recommend that you use it during the day. Keep in mind that more isn’t always better. Overuse of a SAD lamp can produce insomnia or other side effects.
- Follow manufacturer recommendations for the position: Your lamp should come with recommendations for how close you should position yourself to it. This is very important, as your distance from it will affect the lamp’s lux capacity.
- Position the lamp so that it’s providing you with downward light: This will ensure that it doesn’t shine directly into your eyes.
- Talk with your doctor about how to best stop using the lamp: It may be most appropriate for you to wean yourself off slowly. Spending time outdoors, especially in the mornings, can help this process.
Although light therapy is helpful for people who bipolar disorder, be sure to consult with a doctor before introducing it daily. A medical professional who is familiar with your physical and mental health history will be able to help you figure out if light therapy is a good option for you.
Some studies show that SAD lamps can help boost mood and alleviate symptoms of seasonal depression, but they’re not a substitute for proper mental health care. If you feel that your depression is severe or you experience any of the following symptoms, it’s time to speak with a healthcare professional. Check in with a doctor or mental health professional if:
- You feel sad and hopeless nearly every day.
- You no longer experience pleasure in hobbies or activities you used to enjoy.
- You can’t sleep or are spending too much time sleeping.
- You’re feeling irritated and annoyed nearly every day.
- Symptoms are interfering with your quality of life.
- You’re gaining or losing weight unexpectedly.
Can SAD lamps damage your skin or eyes?
UV light should be filtered out of SAD lamps, so they shouldn’t damage your eyes or skin. However, light boxes used to treat certain skin conditions do emit UV light, so you should be sure that your light box is designed to treat SAD.
Can SAD lamps increase vitamin D levels?
While some people have found that SAD lamps can increase vitamin D levels over time, there’s not enough research to confirm this. Vitamin D is produced by UV light, and most SAD lamps don’t have that.
According to the FDA, UV lights can cause damage to the skin and should be used with caution. Long-term exposure to UV rays can also cause premature aging and skin cancer. If you’re using UV lights on your skin, be sure to speak with your doctor first.
How bright are SAD lamps?
The recommended brightness for SAD lamps is typically 10,000 lux.
How long does it take a SAD lamp to start working?
The University of British Columbia found that people can start to respond to light therapy within a few days and you should see improvements within 2 weeks. Be sure to speak to your doctor if your body does not respond to a SAD lamp after 2 weeks.
Is there anyone who shouldn’t use a SAD lamp?
You should avoid using a SAD lamp if you have an increased sensitivity to light. This may be due to:
- macular degeneration
- a connective tissue disorder
- lupus

SAD can often be alleviated with proactive lifestyle changes. These include:
- going to bed early and waking up at or near dawn
- going outside for extended periods of time, especially first thing in the morning
- avoiding substances that can adversely affect your ability to sleep, such as alcohol
- eating whole, nutrient-rich foods
- exercising
- seeking out professional help from a counselor or therapist
How to find a therapist for seasonal affective disorder
SAD can bring up serious feelings of depression, so consider talking with a mental health professional.
You don’t need to have received a SAD diagnosis to seek out help, though. Even if you’re just feeling more down than usual, it’s OK to talk with a therapist or counselor.
When looking for a mental health professional, you’ll want to specifically search for someone who has experience treating SAD, major depressive disorder, or depressive episodes.
If leaving the house is too intimidating, you can check out online therapy or online psychiatry platforms, too.
Major depressive disorder with seasonal pattern, previously known as seasonal affective disorder (SAD), is a condition caused by lowered exposure to sunlight or a change of seasons. Women and young adults are most affected by this condition.
Using a SAD lamp, also known as a light box, can help alleviate symptoms, boosting your mood.
SAD lamps can be effective when used as a solo treatment or combined with other forms of treatment. Either way, always use these lamps under a doctor’s supervision.

🎖▷ Why You Don't Have to Worry About Weight Gain with Lamictal
psychology
9,239 2 minutes of reading
If you're worried that taking Lamictal (lamotrigine) might cause weight gain, there's good news. It probably won't affect your weight much. If anything, you're more likely to lose weight due to Lamictal than gain weight, but either way, the changes are likely to be pretty small.
The effect of Lamictal on weight has been little studied, and various clinical trials have found minimal effect. In fact, some researchers even considered the drug as a possible remedy for obesity and as a remedy for overeating. This information should be reassuring for people with bipolar disorder, as many of the medications used to treat this condition can cause weight gain.
Lamictal findings and weight gain or loss
Lamictal is an anticonvulsant that can be used to treat seizures such as epilepsy. It is also used as a mood stabilizer for bipolar disorder.
In the first clinical trials with the drug, 5 percent of adults with epilepsy lost weight while taking Lamictal, while 1 to 5 percent of patients with bipolar I disorder gained weight while taking the drug. The researchers do not disclose how much weight patients have gained or lost.
Meanwhile, a 2006 study comparing the effects on weight of Lamictal, lithium, and placebo found that some Lamictal-treated patients gained weight, some lost weight, and most remained about the same weight. Weight changes are usually not many pounds anyway. Obese patients taking Lamictal lost an average of four pounds, while the weight of non-obese patients remained virtually unchanged.
Relationship between weight gain and other bipolar drugs
Weight gain from medications used to treat bipolar disorder is unfortunately quite common. Some mood stabilizers commonly used for bipolar disorder, especially lithium and Depakote (valproate), carry a high risk of weight gain.
In addition, the atypical antipsychotics Clozaril (clozapine) and Zyprexa (olanzapine) tend to cause significant weight gain in people who take them. Finally, some antidepressants, notably Paxil (paroxetine) and Remeron (mirtazapine), have been associated with weight gain.
Therefore, if you are already overweight, you and your psychiatrist may want to consider additional weight gain when determining your bipolar medication regimen. Based on this, Lamictal may be a good choice.
Lamictal as a possible treatment for obesity
Lamictal has also been studied as a possible treatment for obesity in people without epilepsy or bipolar disorder.
In a small clinical study of 40 people conducted in 2006, researchers randomly assigned participants to receive either lamictal or placebo for up to 26 weeks. Each participant in the study had a body mass index (BMI) between 30 and 40, placing them in the obese group to the level of severe obesity. Those who took Lamictal lost an average of just over 10 pounds. Those who took the placebo lost about 7 pounds in the meantime, so while those who took Lamictal lost more weight, they didn't lose all that much more.
Another study in 2009 looked at Lamictal as a remedy for overeating. This study involved 51 people with the condition that 26 of them received Lamictal, and 25 - placebo.
Those who took Lamictal lost more weight than those who took placebo (about 2.5 pounds vs. about one third of a pound) and did have significant improvements in blood sugar and cholesterol lab test results. However, Lamictal did not appear to affect other aspects of the eating disorder when compared to placebo.

How Phototherapy Eases Seasonal Depression and Winter Blues
What is Light Therapy and How Does a Daylight Simulation Phototherapy Device Combat Seasonal Depression?
- Albertych
Most of us live in mid-latitudes, so in winter the sun rises quite late, at 8-9 am, and sets quite early, around 4 pm in December, while on its way it does not rise high above the horizon. Short day lengths combined with low sun exposure lead to a lack of sunlight and vitamin D deficiency. Studies have shown that this can cause your energy levels to drop and your mood to deteriorate, even to depression. In some cases, this can lead to a condition called seasonal major depressive disorder (MDD), also called seasonal affective disorder (SAD).
Light therapy can be used as a supplement to natural sunlight during the autumn/winter period, or at any other time of the year if sun exposure is not sufficient. This can help prevent the likely consequences of a lack of sunlight. But does phototherapy really ease depression and lift your spirits? How does light therapy work? What is the best way to carry it out? What lamps are best for her to use? If in the autumn-winter period your fatigue increases, a feeling of boredom and a depressive state appear, if you become irritable, then this article is for you. Below you will find answers to all the top questions about light therapy, and find out if it can be the remedy that will cheer you up and beat the winter blues.
What is light therapy?
Light therapy, also known as phototherapy, refers to a treatment that uses an artificial light source to compensate for a lack of natural sunlight to relieve the symptoms of seasonal major depressive disorder, other types of depression and mood swings, and sleep disturbances. The patient sits in front of a lamp or light box with sufficient brightness for a certain amount of time each day. As a rule, this procedure is carried out within 30 minutes in the morning shortly after waking up.
How does phototherapy help with winter blues?
Researchers have identified several contributing factors to the depression and low energy levels that many people experience during the winter as a result of the reduced intensity and duration of daily exposure to natural sunlight. For example, a reduction in the duration of the light half of the day leads to a violation of the circadian rhythm of the body. The circadian rhythm is our 24-hour body clock that regulates our sleep and wake cycles. Its violation can greatly affect the production and release of melatonin, disrupt the night's sleep patterns, and also cause fatigue and distraction.
It is likely that light therapy also has an effect on the reuptake of serotonin in the brain. Since serotonin promotes mood and happiness, many antidepressants actually work by increasing the reuptake of this neurotransmitter. At the same time, although the mechanism of this process is not fully understood, it seems that phototherapy also increases the reuptake of serotonin by receptors in the brain and helps regulate the circadian rhythm to its more ideal state. It has been found that light therapy helps to get rid of seasonal depression, helps to normalize sleep patterns, improve mood and increase concentration.
What does phototherapy include for seasonal depression?
If you are experiencing symptoms of seasonal depression, it is worth consulting with your doctor to discuss individual treatment options. However, a typical phototherapy protocol involves the use of a specialized phototherapy box or lamp for at least half an hour in the morning after waking up or shortly thereafter. For best results, the treatment should be carried out daily and according to when and for how long you are exposed to the light source. Light therapy should be practiced from late autumn to early spring.
The general recommendation for the treatment of seasonal affective disorder is to use a lamp with a brightness of at least 10,000 lux (a unit of illuminance) for at least half an hour each morning. For a better understanding, let's make a comparison: on a cloudy day, the observed brightness can be about 1000 lux, and on a clear day in the sun - 10,000 - 30,000 lux.
The brighter and more powerful the lightbox, the more efficient and effective the sessions will be. If you don't see results after two weeks of treatment, consider extending the lightbox exposure to one hour.
Benefits of Light Therapy
Quite often, light therapy begins to show positive results within a few days, although in some cases it may take up to two weeks of treatment to get the desired effect. The most commonly cited benefits of phototherapy include:
- Improved mood
- Improved sleep patterns
- Increased energy levels
- Improved focus
- Drug-free alternative to antidepressants
- Relatively inexpensive and accessible treatment
- Considered safe for most people
- Minimal side effects
Studies have shown that for some people, light therapy can be a fairly effective alternative to pharmacological treatment of the seasonal manifestation of major depressive disorder, and can also be an effective adjunct for other types of treatment.
Side effects of light therapy
Some people tolerate light therapy with few side effects. In addition, phototherapy may be contraindicated for people with certain vision problems, skin cancers and skin sensitivity, and those who use medications that increase photosensitivity. Here are the most commonly observed side effects reported by some people:
- Headaches
- Light nausea
- Eye overwork
- Irritability
- Problems with
- Fatigue
How to choose a daylight for phototherapy
Currently, many light -thelerts and other devices are available on the Internet and other devices and simulated daylight.
