These body image journal prompts are helpful in identifying, working through, and overcoming body image struggles.
Journaling has been found to have tons of insanely compelling benefits for mental health, personal development, productivity, self-discovery, and overall well-being.
Journaling is special in the way it allows you to express your innermost thoughts and feelings without having to tell anyone outside of yourself. It can be intimidating to confide in another human about your private feelings. With journaling, you get the emotional release of expression without having to face a tough conversation.
That is one of the many reasons I wholeheartedly believe in the power of journaling. Within my own struggles with body image and mental illness, journaling has been a lifesaver.
Why Journal for Body Image?
Journaling for body image can be one of the most helpful tools on your journey to body acceptance and self-love.
With these body image journal prompts, it is my hope that I can help guide you to liberation and freedom from negative body thoughts.

Present Day Body Image Journal Prompts | Body Acceptance
These prompts are intended to help you achieve body acceptance through journaling for body image.
Body acceptance is exactly what it sounds like… simply accepting your body.
Body acceptance, also known as body neutrality, does not put emphasis on your physical appearance but, rather, helps to build an appreciation for what your body DOES – not what it LOOKS LIKE.
11. What is something my body does for me that makes it unique?
12. How does my body work for me every day?

13. List 10 things you appreciate about your body.
Some of my favorite ideas from my own body image journaling: my arms allow me to hug my mom, my nose allows me to smell home-cooked meals, and my legs take me to new places.
14. What is your favorite form of movement?
15. How does that movement (above) make you feel?
16. What is a unique talent you can do with your body?
17.
What was your favorite thing about your body as a kid? How do you feel about that part of your body now? Why the shift?
18. When do you feel the strongest?
19. What part of your body is the strongest? Write about all it does for you.
This doesn’t have to be physical strength… this could be about mental strength or a strong heart.
20. Write about a time your body has protected you. Reflect on how amazing that is.
This could be recovering from the flu, healing a cut, etc. It’s amazing how much our body does FOR us.
21. Simply make a list of as many body parts as you can think of.
22. Continue your list above by adding the function of each body part.
23. List physical characteristics of yourself. (ie. my hair is blonde, my eyes are blue, etc.)
These past three prompts may sound silly but this has really helped me improve my body image.
Disassociating body parts with a physical appearance and focusing, instead, on the functionality can be so helpful.

Correct image in kaleidoscope | Article in the journal "Young scientist"
It contains the magic of mirrors and a handful of fragments.
As you want - so cool, on business and without business.
Mysterious essence inside kaleidoscopes
Open only to those who looked through the glass!
Everyone is familiar with a wonderful toy - a kaleidoscope. Iridescent patterns are fascinating, you can sit for hours and look at them, because the endless world of the looking glass is very interesting and mysterious. The world behind the looking glass of a kaleidoscope is mysterious in that its image must be correct. It became interesting for me to understand the endless looking glass and how the correct image is formed in it and what it depends on. nine0003
Purpose of the study: Find out what the correct image in a kaleidoscope is and how it depends on the line prism that is inside it.
Research objectives:
- Find and study theoretical material on the topic "Mirror and rotational symmetry";
- Find out what principle is inherent in the work of a kaleidoscope;
- Investigate the dependence of the number of images on the angle between the mirrors; familiarize yourself with the kaleidoscope device; find out what is the correct image in a kaleidoscope; nine0034
- Collect information about kaleidoscopes and various direct prisms in them; find out with which direct prisms the correct image is obtained; compare the disadvantages and advantages of direct prisms when used in a kaleidoscope;
- Make your own kaleidoscope;
- Summarize the information obtained from the study.
Research hypothesis:
The correct image in a kaleidoscope depends on which straight prism is inside it. nine0003
Materials and methods: analysis, synthesis, generalization and systematization of the collected information, experiment.
Although the kaleidoscope seems like magic to us, it is not, because the endless mysterious world of the kaleidoscope is based on the laws of mathematics, geometry and physics: mirror and rotational symmetry; principle of reflection of light from a flat mirror.
Kaleidoscope (the word comes from three Greek words - beautiful, view, look). It is believed that the Scottish physicist David Brewster invented the kaleidoscope. In 1816 he patented his kaleidoscope. nine0003
Symmetry ( from the Greek "symmetria") - means the sameness in the arrangement of parts.
In a kaleidoscope, two types of symmetry are combined: mirror and rotation.
By placing the mirrors at a certain angle, you can see the reflection, the reflection of the reflection, etc.
Reflection — this is the most well-known and most commonly occurring type of symmetry in nature. The mirror reproduces exactly what it "sees", but reverses the spatial order: for example, your double's right hand will be left because the fingers will be placed on it in reverse order. nine0003
Mirror symmetry — this is such a symmetry when one figure mirrors (repeats) the other, that is, each half serves as a mirror image of the other, and the plane separating them is called the plane of mirror reflection (plane of symmetry).
In the figure, the orange triangle (figure A) - which is the original and is reflected in the mirror, as a result, we get the figure A '- an exact copy of the figure A and which is called an imaginary image. Everything that was on the left became at the same distance from the plane of symmetry (line b) on the right.
nine0003
This is the most common kind of symmetry - we see it everywhere in nature, as well as in art, technology, and even in music, linguistics and other sciences.
Rotational symmetry — with it, the appearance of the pattern does not change if it is rotated through a certain angle around the axis. An example is the children's game "pinwheel" with rotational symmetry.
By combining reflection with rotation, we get what is seen in a kaleidoscope. Both symmetries are necessary to produce an image in a kaleidoscope. nine0003
A kaleidoscope is an optical device based on the principle of reflection of light from flat mirrors that form an angle between them. It is the mirror that has a smooth surface, so it reflects light at a clear angle. At the same time, light is reflected, obeying the law of reflection - this is the principle that underlies the work of a kaleidoscope. It is the mirrors that are used in the kaleidoscope that give an imaginary image located symmetrically with respect to the mirror.

|
|
| The angle of incidence is equal to the angle of reflection | |
It turns out that it is thanks to mirror symmetry and the principle of light reflection from a flat mirror that we see a symmetrical image in a kaleidoscope.
Inside the kaleidoscope can stand from 2-3 mirrors to 4 or more. To understand the principle of operation of a kaleidoscope, I will conduct an experiment with mirrors. Take a mirror and put a chip in front of it. We see two chips: one in the original and one in the reflection “behind the mirror”. In the mirror, we see the image of the chip, located at a distance equal to the distance to the mirror. I will now take two mirrors located at an angle of 120 nine0125 0 to each other, and repeat our experiment. The number of images and the beauty of the picture in a kaleidoscope just depends on the number of mirrors that are in the prism. Angle value in degrees Number of images nine0024 180 2 120 3 90 4 72 five 60 6 45 eight 36 10 thirty 12 Angle decreases The number of images is increasing The kaleidoscope inside is equipped with mirrors set at certain angles with respect to each other (straight prism). In one of the bases of the prism there is a double glass bottom, small multi-colored objects are poured between the glasses. At the opposite base of the prism is an eyepiece. With a fixed position of the kaleidoscope, objects form a picture in the “main” figure. Objects falling into the space between two mirrors are reflected in them, their reflections and reflections of their reflections are reflected. It is repeatedly reflected in the walls of the mirrors, and the observer sees a symmetrically correct multi-colored pattern through the eyepiece. nine0003 When the kaleidoscope is turned, the objects are interspersed, a new pattern appears. Also, the beauty of the pattern also depends on these objects. Consider several right triangular prisms. A right triangular prism whose base is equilateral triangle, with corners 60 0 -60 0 -60 nine0023 0 
We see three chips: one in the original and two in reflection. A mirror angle with a 90° aperture will show the same image four times. And two mirrors, the angle between which is 72 °, will give us a fivefold image. If the angle between the mirrors is 60 0 , then images are 6, 30 degrees -12, etc. As the angle gets smaller, the number of objects increases. t. e. - the number of images in nine0024 mirrors depends on the angles between the mirrors . The number of images is equal to the result of dividing 360° by the angle between the mirrors, i.e. 180 0 , 120 0 .90 0 .72 0 .60 0 , 45°, 36 0 , thirty 0 etc. Depending on the number by which the division is made, we see the chip 2, 3, 4, 5, 6, 8, 10 and 12 times. The chip makes a “full revolution” in the mirror. Thus, it forms a symmetrical pattern.
nine0003
The picture formed in the fundamental triangle (a). Let's replace it with a simpler one, mathematically related to the fundamental triangle itself - three multi-colored arrows (Appendix 6b), of the same length, laid off from the center of the triangle perpendicular to the mirrors.
If we had one mirror, then everything would end there: the overall picture would consist of a fundamental triangle and its image in the mirror (c). But in the case of a kaleidoscope, all three sides of the fundamental triangle are mirrored, and, therefore, the observer will certainly see the fundamental triangle itself and its three copies symmetrical with respect to the sides nine0311 (G). In fact, as we know from practice, the picture will be much larger. The fact is that the reflections of a mirror in a mirror again “work” like a mirror. That is, nature continues to symmetrically reflect copies of triangles with respect to their "virtual" sides (e). The resulting picture should fill the entire plane (e), different copies-reflections of the fundamental triangle should not overlap each other, creating a hodgepodge, should not be cut off - this is how an infinite world behind the looking glass is obtained.
nine0003
A kaleidoscope is a tube, looking through which you see a fantastically beautiful pattern of multi-colored polygons. The images are superimposed on each other. And these images in the kaleidoscope must meet the requirements for the images to be correct.
Namely, the main characteristic of a regular kaleidoscope is that the image obtained after reflection in the mirrors should not change (stability (s)). And it is really stable: if you shake the kaleidoscope, the image will not change. Even in those places where the edge between the mirrors of the kaleidoscope moves relative to the pattern, it remains constant regardless of the position of the kaleidoscope and its edges. nine0003
It is important that the visible picture " stable ”, does not change with small perturbations of the kaleidoscope. If the pattern is “stable” and symmetrical throughout the entire infinite world behind the looking glass, then only in this case will the image be correct, and only in this case will the device be a kaleidoscope.

Are there any other cases?
To answer this question, I conducted another experiment:
Consider a right triangular prism whose base is arbitrary triangle with any other angle .
In this case, an arbitrary triangle has a discrepancy in the reflections of the first order - relative to the sides of the fundamental triangle itself. The images obtained by reflections relative to the sides are not symmetrical to each other (a). i.e. The image is formed in each of the mirrors separately according to the already indicated principle "the image of a mirror in a mirror, again works like a mirror." But the image formed in one of the mirrors is not re-reflected in the other mirror. (b). nine0003
Also, in the case of an arbitrary triangle, if you start making further all kinds of its reflections on the plane, they will overlap each other, the image will be composed of somehow mixed fragments of the original image and will not be regular and about any beautiful symmetrical, much less correct image needless to say (c). The surprises presented by a triangle with arbitrary angles do not end there - instability and variability of the image appear (d). nine0003

To prove this, I conducted another experiment, where I took the triangle as a fundamental triangle , with corners 120 0 nine0024 -thirty 0 -thirty 0 , t.
i.e. we see that NOT ANY right triangular prism creates the correct image in kaleidoscope.

Thus, when the kaleidoscope is turned, objects are poured, new and new patterns appear.
To ensure the symmetry of the pattern, its stability, so that there is no inconsistency of images, overlapping of images on each other - and thus the correct image in a kaleidoscope, only the following straight triangular prisms are suitable:
- A triangular prism whose base is nine0023 equilateral triangle, with corners 60 0 -60 0 -60 0 .
- A triangular prism whose base is right-angled isosceles triangle, with corners 90 0 -45 nine0024 0 -45 0
- A triangular prism whose base is right triangle, with corners 90 0 -thirty 0 -60 0 .
But the most common type of kaleidoscope is a triangular prism, which is based on an equilateral triangle with angles of 60 nine0125 0 -60 0 -60 0 - this option is also convenient from a production point of view - all mirrors are the same.
If at the base of a mirror straight prism we use not a triangle, but an arbitrary polygon, then the correct image in the kaleidoscope will be obtained only when using four mirrors placed on the sides of the rectangle, i.e. when using straight quadrangular prism . nine0003
Unfortunately, our eye, looking through the peephole of a kaleidoscope, does not see the entire endless world behind the looking glass that is formed in a kaleidoscope - and therefore many people believe that any direct prism can be used in a kaleidoscope. To prove it, I did an experiment:
Neither what other straight prisms are not suitable for creating a kaleidoscope, i.
e. k. they will not create correct picture in kaleidoscope. nine0024
An image can be called correct only when it is symmetrical, without overlaps and stable in all the endless displays of the kaleidoscope.

then. Hypothesis: The correct image in a kaleidoscope depends on which direct prism to be inside it has found its own the confirmation
AT conclusion of my research, I made 2 of my own kaleidoscopes from a can of chips (https://stranamasterov.
ru/node/950689) with a regular triangular prism and a straight quadrangular prism.
RESULTS:
The pattern generated by the kaleidoscope mirrors, at the right chosen angle, has both mirror and rotational symmetry.
The basic principle that underlies the kaleidoscope is: the principle of light reflection from a flat mirror, thanks to which, by placing mirrors at a certain angle, we see symmetrical reflection, reflection reflection, etc. The number of images and the beauty of the pattern in a kaleidoscope depends on the number of mirrors, which are in the prism. nine0003
The beauty of the image in a kaleidoscope also depends on the decorative filling that is used in the kaleidoscope device. An image in a kaleidoscope is considered correct when it is symmetrical, without overlaps, and stable in all the infinite displays of the kaleidoscope.
The correct image in a kaleidoscope can only be achieved by using 4 types of direct prisms in its device:
1.
Triangular prism, at the base of which lies an equilateral triangle, with angles of 60 nine0125 0– 60 0– 60 0 .
2. Triangular prism based on a right isosceles triangle with angles of 90 0– 45 0– 45 0
3. Triangular prism, at the base of which lies a right triangle, with angles of 90 0– thirty 0– 60 0 .
4. Quadrangular prisms.

Why Instagram spoils the mood - Knife
Recent events have confirmed the results of many years of independent research showing that Instagram use is often correlated with body dissatisfaction and an increased tendency to diet. And the first leads to the last very quickly.
In one of the experiments involving female students, it was found that just seven minutes of using Instagram is enough to spoil the user's mood. nine0003
There are a million suggestions on how to counteract the damage caused by a constant stream of idealized images of friends and strangers. Among them, filtering your Instagram feed and focusing on the capabilities of your body, and not on how it looks. Some are trying to fight the avalanche of ad-like images with body-positive images showing bodies of different shapes, sizes and colors. If none of that helps, there are other apps that can help reduce the amount of time you spend on other apps. nine0003
However, none of these methods address the core of the problem. Complexes about your body are just the tip of the iceberg. Once you have learned to view your body as an object, you cannot unlearn it, says René Engeln , professor of psychology at Northwestern University (USA) and founder of the Body and Media Lab .
The most effective method is more radical than anything proposed so far: stop producing and consuming images of bodies. Try to look less at others and put yourself on display less. nine0003
Let's take a quick look at the history of narcissism. For many thousands of years, one could see oneself only in a natural reflective surface, for example, in a lake. About five hundred years ago, glass mirrors appeared. Less than two hundred years ago, the first photographs were taken. And in 2010, Kevin Systrom posted his first photo on Instagram.
Mirrors have radically changed people's attitude to their appearance. However, in their reflection, you can only look at yourself - photography has brought the ability to capture and hold the image. nine0003
“To photograph means to appropriate the object being photographed, to place oneself in relation to the world in a position of knowledge, and therefore of power,” wrote Susan Sontag (On Photography, 1977).
Today, people take 1.
4 trillion photos a year, 82% of young Americans have posted a selfie online at least once, and any image can be shared in seconds on any of dozens of platforms to immediately get likes or comments. It is difficult to say who owns the power that Sontag spoke of. nine0003
For more than two decades, Engeln and her colleagues have been saying that popular media - tabloids, television television and now social networks - exacerbate objectification, that is, the habit of viewing other people not as individuals, but as objects aesthetic evaluation. According to the researchers, this gradually leads to the fact that a person's self-esteem is directly dependent on appearance. Then arise shame, anxiety, depression and eating disorders.
People are also starting to spend more and more time on self-observation. Experiments show that seemingly trivial circumstances, such as the proximity of mirrors and scales, or receiving a comment about appearance, lead to a slowdown in cognitive activity: attention switches from the task being performed to the perception of one's body.
As a consequence, writes Engeln in his book Obsessed with Beauty (2018), an invisible mirror constantly separates people from the outside world. nine0003
The tendency to self-objectify is so deeply ingrained in social media users that even life's wisdom cannot help overcome it, says Engeln. Disclaimers like "This image has been manipulated" do more harm than good by causing people to scrutinize images of idealized bodies even more. This is similar to the situation with trigger warnings.
“It is impossible to grow out of an obsession with beauty,” writes Engeln. “It can only be got rid of through conscious intention and determination.” nine0003
The desire to look at others and expose oneself does not weaken, even though it leads to negative emotions. Hence the constant attempt to balance the retouched images of influencers with unedited photographs of ordinary people living healthy and happy lives.
But viewing any, even body-positive, posts that focus on appearance can lead to self-objectification.
Scientists from Australia conducted a study, the results of which were published in 2019year in New Media & Society magazine. During the experiment, 195 women aged 18 to 30 were shown images of bodies and noted their reactions. It turned out that photographs of various bodies contributed to a slight increase in mood, while those who looked at idealized images had a sharp drop in mood. At the same time, participants from both groups talked more about appearance immediately after viewing the images.
At least one of these results is positive. However, Instagram is not a controlled psychological experiment. Even those who follow pet, plant, and body-positive content will still see a huge amount of retouched celebrity images, ads, and posts related to weight loss and promoting anorexia in their feed. nine0003
“When the goal is more subscribers, more time spent on the site, and more content, user mental health takes a back seat as one conflicts with the other,” says Engeln.
As you can see, all the power is in the hands of the leaders of Facebook.
Most people are unable to love their body all the time. Moreover, this is not always desirable , as it makes you get hung up on certain aspects of your appearance. That is why philosophy arose0962 body neutrality , the main idea of which is to appreciate your body and think less about how it looks.
The recent comparison of Facebook's policies with those of the big tobacco companies, who knew about the harm their products were causing but hid the fact, is another reason to stop looking at other people's photos and post your own.
For most people, the pandemic is the best opportunity to distance themselves from their looks.
“This year, thanks to Zoom meetings, iMessage, Crowdcast readings, and Slack internal correspondence, I’ve come close to realizing my dream of being a brain in a flask,” author and editor Jess Zimmerman wrote in February.
When Engeln began to explore the self-perception of a person in the world of media, the main problem was the tabloids near the checkout tape in the supermarket. If you have to stand near a magazine stand for a long time, she wrote in her book, turn magazines upside down. The emergence of new spaces for the distribution and viewing of body images requires new measures to counter them. Uninstall image sharing apps. Require brands to advertise products, not people. Turn off the TV. nine0003
“I understand that young people will not give up on all this,” says Engeln, adding that she carefully filters her Instagram feed herself, “but I dream that one day people will stop putting up with the situation.”
Is Enegln right?
First, by asserting the dependence of people's behavior on environmental stimuli, critics of self-objectification deny the free will of a person - that is, they sin precisely by what they oppose.
Secondly, removing images of bodies from the Internet goes against the goal of giving voice to non-white people, people with disabilities, trans and non-binary people, and everyone else who lives in bodies that are traditionally marginalized.
