Reduce Your Health Risk

The good news is that moderate physical activity, such as brisk walking, is generally safe for most people.

Cardiovascular Disease

Heart disease and stroke are two leading causes of death in the United States. Getting at least 150 minutes a week of moderate physical activity can put you at a lower risk for these diseases. You can reduce your risk even further with more physical activity. Regular physical activity can also lower your blood pressure and improve your cholesterol levels.

Type 2 Diabetes and Metabolic Syndrome

Regular physical activity can reduce your risk of developing type 2 diabetes and metabolic syndrome. Metabolic syndrome is some combination of too much fat around the waist, high blood pressure, low high-density lipoproteins (HDL) cholesterol, high triglycerides, or high blood sugar. People start to see benefits at levels from physical activity even without meeting the recommendations for 150 minutes a week of moderate physical activity. Additional amounts of physical activity seem to lower risk even more.

Strengthen Your Bones and Muscles

As you age, it’s important to protect your bones, joints, and muscles – they support your body and help you move. Keeping bones, joints, and muscles healthy can help ensure that you’re able to do your daily activities and be physically active.

Muscle-strengthening activities like lifting weights can help you increase or maintain your muscle mass and strength. This is important for older adults who experience reduced muscle mass and muscle strength with aging. Slowly increasing the amount of weight and number of repetitions you do as part of muscle strengthening activities will give you even more benefits, no matter your age.

Improve Your Ability to do Daily Activities and Prevent Falls

Everyday activities include climbing stairs, grocery shopping, or playing with your grandchildren. Being unable to do everyday activities is called a functional limitation. Physically active middle-aged or older adults have a lower risk of functional limitations than people who are inactive.

For older adults, doing a variety of physical activity improves physical function and decreases the risk of falls or injury from a fall. Include physical activities such as aerobic, muscle strengthening, and balance training. Multicomponent physical activity can be done at home or in a community setting as part of a structured program.

Hip fracture is a serious health condition that can result from a fall. Breaking a hip have life-changing negative effects, especially if you’re an older adult. Physically active people have a lower risk of hip fracture than inactive people.

Increase Your Chances of Living Longer

See physical activity recommendations for different groups, including:

Children age 3-5.
Children and adolescents age 6-17.
Adults age 18-64.
Adults 65 and older.
Adults with chronic health conditions and disabilities.
Healthy pregnant and postpartum women.

An estimated 110,000 deaths per year could be prevented if US adults ages 40 and older increased their moderate-to-vigorous physical activity by a small amount. Even 10 minutes more a day would make a difference.

Taking more steps a day also helps lower the risk of premature death from all causes. For adults younger than 60, the risk of premature death leveled off at about 8,000 to 10,000 steps per day. For adults 60 and older, the risk of premature death leveled off at about 6,000 to 8,000 steps per day.

Manage Chronic Health Conditions & Disabilities

Regular physical activity can help people manage existing chronic conditions and disabilities. For example, regular physical activity can:

Reduce pain and improve function, mood, and quality of life for adults with arthritis.
Help control blood sugar levels and lower risk of heart disease and nerve damage for people with type 2 diabetes.
Help support daily living activities and independence for people with disabilities. Also see:

The Top 10 Benefits of Regular Physical Activity

Exercise is defined as any movement that makes your muscles work and requires your body to burn calories.

There are many types of physical activity, including swimming, running, jogging, walking, and dancing, to name a few.

Being active has been shown to have many health benefits, both physically and mentally. It may even help you live longer (1).

Here are the top 10 ways regular exercise benefits your body and brain.

1. Exercise can make you feel happier

Exercise has been shown to improve your mood and decrease feelings of depression, anxiety, and stress (2).

It produces changes in the parts of the brain that regulate stress and anxiety. It can also increase brain sensitivity to the hormones serotonin and norepinephrine, which relieve feelings of depression (3).

Additionally, exercise can increase the production of endorphins, which are known to help produce positive feelings and reduce the perception of pain (3).

Interestingly, it doesn’t matter how intense your workout is. It seems that exercise can benefit your mood no matter the intensity of the physical activity.

In fact, in a study in 24 women diagnosed with depression, exercise of any intensity significantly decreased feelings of depression (4).

The effects of exercise on mood are so powerful that choosing to exercise (or not) even makes a difference over short periods of time.

One review of 19 studies found that active people who stopped exercising regularly experienced significant increases in symptoms of depression and anxiety, even after only a few weeks (5).

Summary
Exercising regularly can improve your mood and reduce feelings of anxiety and depression.

2. Exercise can help with weight loss

Some studies have shown that inactivity is a major factor in weight gain and obesity (6, 7).

To understand the effect of exercise on weight reduction, it is important to understand the relationship between exercise and energy expenditure (spending).

Your body spends energy in three ways:

digesting food
exercising
maintaining body functions, like your heartbeat and breathing

While dieting, a reduced calorie intake will lower your metabolic rate, which can temporarily delay weight loss. On the contrary, regular exercise has been shown to increase your metabolic rate, which can burn more calories to help you lose weight (6, 7, 8).

Additionally, studies have shown that combining aerobic exercise with resistance training can maximize fat loss and muscle mass maintenance, which is essential for keeping the weight off and maintaining lean muscle mass (9, 10, 11).

Summary
Exercise is crucial to supporting a healthy metabolism and burning more calories per day. It also helps you maintain your muscle mass and weight loss.

3. Exercise is good for your muscles and bones

Exercise plays a vital role in building and maintaining strong muscles and bones.

Activities like weightlifting can stimulate muscle building when paired with adequate protein intake.

This is because exercise helps release hormones that promote your muscles’ ability to absorb amino acids. This helps them grow and reduces their breakdown (12, 13).

As people age, they tend to lose muscle mass and function, which can lead to an increased risk of injury. Practicing regular physical activity is essential to reducing muscle loss and maintaining strength as you age (14).

Exercise also helps build bone density when you’re younger, in addition to helping prevent osteoporosis later in life (15).

Some research suggests that high impact exercise (such as gymnastics or running) or odd impact sports (such as soccer and basketball) may help promote a higher bone density than no impact sports like swimming and cycling (16).

Summary
Physical activity helps you build muscles and strong bones. It may also help prevent osteoporosis.

4. Exercise can increase your energy levels

Exercise can be a real energy booster for many people, including those with various medical conditions (17, 18).

One older study found that 6 weeks of regular exercise reduced feelings of fatigue for 36 people who had reported persistent fatigue (19).

And let’s not forget the fantastic heart and lung health benefits of exercise. Aerobic exercise boosts the cardiovascular system and improves lung health, which can significantly help with energy levels.

As you move more, your heart pumps more blood, delivering more oxygen to your working muscles. With regular exercise, your heart becomes more efficient and adept at moving oxygen into your blood, making your muscles more efficient (20).

Over time, this aerobic training results in less demand on your lungs, and it requires less energy to perform the same activities — one of the reasons you’re less likely to get short of breath during vigorous activity (21).

Additionally, exercise has been shown to increase energy levels in people with other conditions, such as cancer (22).

Summary
Engaging in regular physical activity can increase your energy levels.

5. Exercise can reduce your risk of chronic disease

Lack of regular physical activity is a primary cause of chronic disease (23).

Regular exercise has been shown to improve insulin sensitivity, heart health, and body composition. It can also decrease blood pressure and cholesterol levels (24, 25, 26, 27).

More specifically, exercise can help reduce or prevent the following chronic health conditions.

Type 2 diabetes. Regular aerobic exercise may delay or prevent type 2 diabetes. It also has considerable health benefits for people with type 1 diabetes. Resistance training for type 2 diabetes includes improvements in fat mass, blood pressure, lean body mass, insulin resistance, and glycemic control (28).
Heart disease. Exercise reduces cardiovascular risk factors and is also a therapeutic treatment for people with cardiovascular disease (29).
Many types of cancer. Exercise can help reduce the risk of several cancers, including breast, colorectal, endometrial, gallbladder, kidney, lung, liver, ovarian, pancreatic, prostate, thyroid, gastric, and esophageal cancer (30).
High cholesterol. Regular moderate intensity physical activity can increase HDL (good) cholesterol while maintaining or offsetting increases in LDL (bad) cholesterol. Research supports the theory that high intensity aerobic activity is needed to lower LDL levels (31).

Hypertension: Participating in regular aerobic exercise can lower resting systolic BP 5–7 mmHG among people with hypertension (32).

In contrast, a lack of regular exercise — even in the short term — can lead to significant increases in belly fat, which may increase the risk of type 2 diabetes and heart disease (23).

That’s why regular physical activity is recommended to reduce belly fat and decrease the risk of developing these conditions (33).

Summary
Daily physical activity is essential to maintaining a healthy weight and reducing the risk of chronic disease.

6. Exercise can help skin health

Your skin can be affected by the amount of oxidative stress in your body.

Oxidative stress occurs when the body’s antioxidant defenses cannot completely repair the cell damage caused by compounds known as free radicals. This can damage the structure of the cells and negatively impact your skin.

Even though intense and exhaustive physical activity can contribute to oxidative damage, regular moderate exercise can actually increase your body’s production of natural antioxidants, which help protect cells (34, 35).

In the same way, exercise can stimulate blood flow and induce skin cell adaptations that can help delay the appearance of skin aging (36).

Summary
Moderate exercise can provide antioxidant protection and promote blood flow, which can protect your skin and delay signs of aging.

7. Exercise can help your brain health and memory

Exercise can improve brain function and protect memory and thinking skills.

To begin with, it increases your heart rate, which promotes the flow of blood and oxygen to your brain. It can also stimulate the production of hormones that enhance the growth of brain cells.

Plus, the ability of exercise to prevent chronic disease can translate into benefits for your brain, since its function can be affected by these conditions (37).

Regular physical activity is especially important in older adults since aging — combined with oxidative stress and inflammation — promotes changes in brain structure and function (38, 39).

Exercise has been shown to cause the hippocampus, a part of the brain that’s vital for memory and learning, to grow in size, which may help improve mental function in older adults (38, 39, 40).

Lastly, exercise has been shown to reduce changes in the brain that can contribute to conditions like Alzheimer’s disease and dementia (41).

Summary
Regular exercise improves blood flow to the brain and helps brain health and memory. Among older adults, it can help protect mental function.

8. Exercise can help with relaxation and sleep quality

Regular exercise can help you relax and sleep better (42, 43).

With regard to sleep quality, the energy depletion (loss) that occurs during exercise stimulates restorative processes during sleep (44).

Moreover, the increase in body temperature that occurs during exercise is thought to improve sleep quality by helping body temperature drop during sleep (45).

Many studies on the effects of exercise on sleep have reached similar conclusions.

One review of six studies found that participating in an exercise training program helped improve self-reported sleep quality and reduced sleep latency, which is the amount of time it takes to fall asleep (46).

One study conducted over 4 months found that both stretching and resistance exercise led to improvements in sleep for people with chronic insomnia (47).

Getting back to sleep after waking, sleep duration, and sleep quality improved after both stretching and resistance exercise. Anxiety was also reduced in the stretching group (47).

What’s more, engaging in regular exercise seems to benefit older adults, who are often affected by sleep disorders (48, 49).

You can be flexible with the kind of exercise you choose. It appears that either aerobic exercise alone or aerobic exercise combined with resistance training can both improve sleep quality (50).

Summary
Regular physical activity, regardless of whether it is aerobic or a combination of aerobic and resistance training, can help you sleep better and feel more energized during the day.

9. Exercise can reduce pain

Although chronic pain can be debilitating, exercise can actually help reduce it (51).

In fact, for many years, the recommendation for treating chronic pain was rest and inactivity. However, recent studies show that exercise helps relieve chronic pain (52).

In fact, one review of several studies found that exercise can help those with chronic pain reduce their pain and improve their quality of life (52).

Several studies also show that exercise can help control pain associated with various health conditions, including chronic low back pain, fibromyalgia, and chronic soft tissue shoulder disorder, to name a few (52).

Additionally, physical activity can also raise pain tolerance and decrease pain perception (53, 54).

Summary
Exercise has favorable effects on the pain associated with various conditions. It can also increase pain tolerance.

10. Exercise can promote a better sex life

Exercise has been proven to boost sex drive (55, 56, 57).

Engaging in regular exercise can strengthen the heart, improve blood circulation, tone muscles, and enhance flexibility, all of which can improve your sex life (56).

Physical activity can also improve sexual performance and sexual pleasure while increasing the frequency of sexual activity (56, 58).

Interestingly enough, one study showed that regular exercise was associated with increased sexual function and desire in 405 postmenopausal women (59).

A review of 10 studies also found that exercising for at least 160 minutes per week over a 6-month period could help significantly improve erectile function in men (57).

What’s more, another study found that a simple routine of a 6-minute walk around the house helped 41 men reduce their erectile dysfunction symptoms by 71% (60).

Yet another study demonstrated that women with polycystic ovary syndrome, which can reduce sex drive, increased their sex drive with regular resistance training for 16 weeks (61).

Summary
Exercise can help improve sexual desire, function, and performance in men and women. It can also help decrease the risk of erectile dysfunction in men.

The bottom line

Exercise offers incredible benefits that can improve nearly every aspect of your health. Regular physical activity can increase the production of hormones that make you feel happier and help you sleep better.

It can also:

improve your skin’s appearance
help you lose weight and keep it off
reduce the risk of chronic disease
improve your sex life

And it doesn’t take much movement to make a big difference in your health.

If you aim for 150 to 300 minutes of moderate intensity aerobic activity each week or 75 minutes of vigorous physical activity spread throughout the week, you’ll meet the Department of Health and Human Services’ activity guidelines for adults (62).

Moderate intensity aerobic activity is anything that gets your heart beating faster, like walking, cycling, or swimming. Activities like running or participating in a strenuous fitness class count for vigorous intensity.

Throw in at least 2 days of muscle-strengthening activities involving all major muscle groups (legs, hips, back abdomen, chest, shoulders, and arms), and you’ll exceed the recommendations.

You can use weights, resistance bands, or your bodyweight to perform muscle-strengthening exercises. These include squats, push-ups, shoulder press, chest, press, and planks.

Whether you practice a specific sport or follow the guideline of 150 minutes of activity per week, you can inevitably improve your health in many ways (55).

Electronic signature (ES) is an integral part of modern document management. Running a modern business is simply impossible to imagine without its use. The ES helps to identify the author of the signed document, determine whether changes were made to the document after it was signed, and also ensures the legal significance of the signed document. An electronic signature also solves many problems for individuals, eliminating paperwork and making their daily lives easier.

In order to start enjoying all the benefits of an electronic signature, you will need to purchase a key carrier (token or smart card), obtain an electronic signature certificate, and in some cases install special cryptographic software responsible for generating a key pair (signature key). and signature verification key). Such software can be installed on a computer independently or in a Certification Authority (CA) that issues electronic signature certificates, or it can be part of the key carrier itself, performing cryptographic operations directly “on board” the device - a token or a smart card. Let's see why the latter option should be more preferable for the user.

Signature key security properties

As we wrote earlier - in order to avoid compromising your electronic signature, it is extremely important to keep the ES key secret! The security of signing keys depends on the exportability and retrievability properties, as well as the functionality of the token or smart card on which they are stored. Therefore, as carriers of electronic signature keys, it is recommended to use secure active key carriers (for example, Rutoken EDS 2.0 2100) with cryptographic information protection functions built into the hardware level. We described in sufficient detail about the difference between active and passive key carriers in the material What is an ES key compromise and why does it happen. In this article, we will dwell on the properties of active key carriers, or, in other words, cryptographic key carriers, in more detail.

Non-exportable property

Non-exportable signature keys are more secure than exported keys. However, both of these types of keys are retrievable keys. When generating an electronic signature, such keys are read into the computer's RAM after the PIN code is presented.

The difference is that a non-exportable key written to a key medium cannot be copied by standard means of cryptographic information protection. Information security experts recommend using non-exportable keys, since gaining access to such a key requires the use of special tools and techniques.

The property of exportability or non-exportability of the signature key is assigned at the stage of generating the signature key and writing it to a secure key medium.

Non-removable property

The non-recovery property of the signature key is achieved when it is stored and used only in a special and microprocessor-protected memory area of the key carrier. Access to protected memory is carried out using a non-editable list of microprocessor instructions. It is important that the processor does not contain a command that allows access from the outside to the contents of the key. To ensure the non-recovery property of the signature key, only active key carriers are used that contain the hardware-implemented functions of the cryptographic information protection facility (CIPF), when using which a non-recoverable key is generated and used.

The use of non-retrievable signature keys on an active key carrier provides the maximum degree of their protection.

What is the main feature of a cryptographic key carrier?

An unrecoverable signing key on an active key carrier is stored in its memory, in a secure key container, in a special internal format. In such a key medium, there is no possibility of reading the signature keys by software, which means that a copy (by cloning) of the user key outside the device's microprocessor cannot appear.

All this means that such a medium has a number of technical advantages over a passive protected key medium:

1) the signature key is generated on the medium itself using the hardware cryptographic functions of the key medium;

2) when signing an electronic document, the signature key is not copied to the computer memory - the signing of the electronic document takes place in the key carrier itself.

The signature key never leaves such a key carrier, therefore its compromise is possible only in case of theft of the key carrier together with the password (PIN code).

An active secure key carrier (cryptographic key carrier) has a much higher level of protection against malicious attacks compared to passive key carriers. In order not to get lost in the multitude of device options, read our article Which token is needed for tax purposes.
