What causes a lack of sunlight? How to make up for the deficit of the sun

01.10.2019

All life on Earth, including man, is constantly under the influence of our celestial body - the Sun. And, despite all the benefits of civilization that we have achieved, in the first place, electricity, we also get up and fall asleep on the Sun. Our general well-being and just a state of mind depend on its rays.

This is most noticeable in those periods when we are forced, for the sake of economic benefit, to move the clock hands an hour forward or backward. or in the winter season. Many of us immediately feel the consequences of such changes.

How does sunlight affect human health?

The most valuable thing that sunlight gives a person is ultraviolet light. It makes our immune system work - but, just in the autumn-winter period, many begin to hurt when there is little light. In the same dark seasons of the year, many people gain weight, because the lack of ultraviolet radiation negatively affects our metabolism. In winter, people are more sleepy and indifferent, and in summer, vice versa. Because bright sunlight increases efficiency, and its lack reduces.

Surely many had to feel bad in the fall only because at that time there was also very little sun. And this is not surprising. The fact is that in sunlight, the human body produces the hormone serotonin, and its second name is the activity hormone. It is produced during daylight hours and is regulated by light intensity. This hormone regulates our sleep and makes us stay alert. Therefore, many experts suggest that the causes of most depression are not personal problems of a person, but a simple lack of sunlight.

Lack of ultraviolet light also affects our skin. For example, in winter, in low light, the skin begins to itch and peel. This happens due to a violation or termination of the formation of vitamin D.

In winter, more often than ever, holes in teeth begin to form.
There is even such an opinion that the lack of sunlight has a bad effect on human vision.

How to make up for the shortage of sunlight for humans?

Tip number 1

More walk. But remember: only walks in the daytime will benefit. To gain the “solar” norm necessary for normal existence, it is enough to put the face and hands of the sun for 10-15 minutes a couple of times a week. By the way, sunbathing in a solarium in order to replenish the supplies of ultraviolet radiation is useless. Artificial sun cannot replace the present.

Tip number 2

Let the light into your home. Wash the windows (dirty ones hold up to 30% of the light) and remove tall flowers from the windowsill (they take 50% of the sun's rays).

Tip number 3

Vitamin D can be replenished with food. The main assistant is fish of fatty varieties. The largest amount (about 360 units per 100 g) of vitamin D is found in salmon. It is rich in omega-3 fatty acids, which also help maintain heart health and suppress all kinds of inflammations. But, even absorbing shock doses of vitamin D, you need to walk - so that it is absorbed.

Tip number 4

The activity hormone serotonin can also be obtained from foods. It is found in dark chocolate, pineapples, bananas, apples and plums.

Tip number 5

It is useless to fight drowsiness - it is better for her to surrender. The peak of drowsiness is from 13 to 17 hours. At this time, it is better to take a nap for 15-20 minutes in a chair, and then wake up vigorous and healthy. A short rest perfectly restores performance. Plus, every hour you should be distracted from work and relax for 5 minutes.

Tip number 6

It is possible to enhance the synthesis of hormones with the help of physical exertion - during training, their increased production occurs. Half an hour of intense physical activity increases the concentration of “hormones of happiness” by 5-7 times. By the way, in the gym you can solve another winter problem - a breakdown. There is evidence that one of the causes of this phenomenon is a lack of movement.

Lack of sunlight negatively affects:

* skin regeneration, hair growth

* mood

* immune system

* performance

* cardiovascular system

* hormonal status

To neutralize the negative consequences will help:

* walks

* sports training

* full sleep

* food including fish, fruit and dark chocolate

Let's try to figure it out. Under the influence of ultraviolet radiation, the body produces serotonin and endorphins - the main "hormones of happiness". These substances have a positive effect on blood coagulation processes, allergic reactions. If hormones are at a level, you, consider, guaranteed a complete passion, personal life, vivacity and good mood.

To make up for serotonin deficiency, many begin to seize grief sweet: Carbohydrate-rich foods activate insulin, which stimulates an increase in tryptophan levels in the blood. What does the new characters have to do with it, you ask? Tryptophan - the amino acid from which serotonin is synthesized. But it is difficult to call such a solution ideal: weight gain usually upsets modern citizens, and the circle closes.

But that's not all. As we know from the course of biology, with the departure of the sun the human body begins to lack vitamin D (calciferol). The latter helps strengthen immunity, the skeletal system and tissues, helps to remove heavy metals from the body, and makes it possible for other vitamins and minerals to be absorbed.

Under the influence of ultraviolet, metabolism is activated, the circulatory system improves. The sun's rays affect the centers of the brain that control the reproductive and endocrine systems. In addition, biologically inert nitrite NO3 is released in the body and is converted to nitrate and nitric oxide, which reduce pressure and reduce the likelihood of heart attacks and strokes.

The sun has an antibacterial effect, the number of acne, rashes decreases, wounds and cuts heal faster. Sunbathing is one of the best remedies for treating rickets, osteomalacia, psoriasis, and is useful even for coronary heart disease.

In general, after all that has been said, it becomes clear why we flutter so carelessly and feel good on fine days. It is a pity, in the cool season, when the sun's rays are moderately intense and are ready to bring only one benefit, there are beautiful clouds and icy rain outside the window.

What to do?

To get started, contact your therapist. The doctor will evaluate your health status and help you choose vitamin D supplement.
Try to highlight several hours a week on fitness (best on the street). Long walks with invigorating blood are also suitable. Exercise combined with fresh air is what you need to release endorphins and serotonin. It is ideal to supplement sports activities with activity in the bedroom, but for this you will have to stir another person from hibernation.
Sign up for a session in a beauty salon (or better, consult a cosmetologist about the duration) lED therapy. Imagine: you are lying with a special mask on your face, and it glows either red or blue. These magical LEDs act on microcirculation and metabolic processes in the skin. So the work of the sebaceous glands is normalized, turgor improves, and wrinkles are smoothed out.

Hello dear readers! Sunlight - what it means to man. Scientists call it that - the beginning of life. More than a century ago, the first studies of sunlight were conducted.

From the article you will find out who or what is able to absorb solar energy. Due to what our internal organs are saturated with it. What the sun's rays are capable of. What diseases helps to treat sunlight.

Why walking in the sunshine is useful and for how long. What vitamin is able to be produced in our body thanks to this gift of God. Skin and sunlight, his and her actions.

sunlight

Sunlight, and indeed light is the beginning of life. Chlorophyll, which is a green pigment in plant leaves, absorbs solar energy. It accumulates in the form of glucose.

Sunlight creates oxygen and carbon dioxide. It is the source that nourishes our body and supplies it with vital energy. The sun's rays kill microorganisms and prevent the growth of mold and fungi.

The fact that sunlight kills microbes was discovered back in 1880 by scientists Downes and Blunt. They discovered this by accident when they saw that the bacteria that were in the shade continued to multiply, and those that fell under the rays of sunlight stopped growing.

Sunlight treatment helps get rid of most infectious diseases. It also helps in the treatment of pneumonia, tonsillitis, fever, etc. Sunlight is able to produce vitamin D in our body when it is exposed to the skin.

Sunlight Energy

What is the energy of sunlight capable of? Is it good for our health? Scientists have come to a very important point regarding the energy of sunlight. It is directly related to improving human health.

How the energy of sunlight helps our health:

stimulating the activity of the immune system enhances immunity
helps with a variety of skin diseases
sunlight is an excellent disinfectant
after pneumonia, tuberculosis and bronchitis, the sun's rays acting on the back or chest help restore

respiratory system

purifies the blood and fills it with oxygen the sun
moderate in the sun will help treat arthritis

Walk in the sunlight

Scientists from Oxford argue that the benefits of sunlight to our health exceed the harmful effects. Walking in the sunlight regulates sleep, improves mood and increases labor productivity.

For people involved in mental work, Neurobiologist R. Foster recommends placing your workplace by the window, especially on a bright sunny day. This will double the person’s attention.

Artificial light does not create such a positive effect. Our scientists also propose to use the maximum light time of the day and more often take walks in the sunlight.

Sunlight deficit

How to make up for the shortage of sunlight:

Tip number 1.Walk more during daylight hours. It is enough two times a week to expose the face and hands to the sunlight for about ten fifteen minutes to gain a “solar” norm for the necessary normal existence.

Tip number 2.Keep your window panes clean and remove tall flowers from windowsills. So you let in and fill the shortage of sunlight in your home.

Tip number 3.There must be a sufficient supply of vitamin D in the body. Your body will get this vitamin through food. The main assistant in this fish is fatty varieties. A lot of vitamin D in Salmon and Omega-3 which are rich in fatty acids. They support heart health and suppress inflammation. In order for Vitamin D to be absorbed, avoid shortages of sunlight. Be sure to take a walk so that he learns.

Lack of sunlight

What is affected by the lack of sunlight:

on the mood
for hair growth and skin regeneration
on working capacity
on the immune system
hormonal balance
on the cardiovascular system

What will help to neutralize the negative consequences:

full sleep
Walks in the sunlight
playing sports
food in which should be present fish, fruit and dark chocolate

With a lack of sunlight, not only people suffer, but also all living things. There is light starvation. When this happens in the winter, itchy and flaky skin. Also, most often in the winter, a larger number of holes in the teeth appear.

What is the danger of lack of sunlight

Walking in the fresh air in sunlight can save a life. Scientists have found that pancreatic cancer can develop due to a lack of sunlight.

People who live in places with frequent cloud cover suffer from a lack of vitamin D. It is very dangerous not to receive ultraviolet radiation for people who have pancreatic cancer.

If you increase the intake of vitamin D in the body, you will not only make effective prophylaxis, but may also have therapeutic effects. What is the danger of a lack of sunlight for people suffering from heart disease.

Every tenth person risks his life, because with a lack of sunlight, the risk of cancer and heart disease increases.

To ensure that you have plenty of vitamin D in your body at all times of the year, eat oily fish and dairy products at least two times a week. Why dairy products? They have a lot of calcium, and calcium, as well as active movement, help vitamin D to be absorbed in the body.

Video about the benefits and harms of sunlight

An absolute factor that ensures the maintenance of life on the planet is sunlight. Despite the fact that the Sun is very far from Earth (as much as 149 million kilometers!), The surface of our planet receives enough solar energy for life, including infrared and ultraviolet radiation, which the human eye is unable to see. Only half of one billionth of the total solar radiation reaches the Earth, nevertheless, the Sun is the main source of energy for all the natural processes that exist on the globe. The whole biosphere exists only due to sunlight.

Studies conducted by scientists from the medical center at the University of Washington in Seattle for ten years have proved that not only the absence, but simply the lack of the sun negatively affects a person. Thanks to sunlight, the human body produces serotonin - the hormone responsible for a large number of physical processes. This hormone is also called the hormone of joy. Lack of serotonin causes winter depression. When people wake up in the dark in winter, go to work darkly and return even when street lighting is already turned on, their body receives an insufficient amount of energy necessary for active life. The result is discomfort, depression, poor health, and even a slowdown in brain activity.

Science Daily published notes by researchers studying the effects of the environment on humans. They collected weather data from NASA satellites to measure exposure to sunlight throughout the United States. A team of researchers from the University of Alabama in Birmingham found a direct correlation between low exposure to sunlight and an increase in the number of people with depression. And among the depressed, the percentage of those with cognitive impairment was high.

Scientists from a research group at the University of Washington found that with a lack of sunlight there are problems with the joints or the lymphatic system. The lack of vitamins A and D, which the sun gives us, leads to insufficient production of calcium, which, in turn, makes our bones fragile: just stumble and fall and you can get a lot of fractures. Israeli scientists from a medical clinic in Tel Aviv analyzed the data of 51 thousand people over 50 years old and came to the conclusion that walks in the sun better protect against fractures than taking calcium.

Researchers at the Hadassah University Hospital in Jerusalem have proven that in Greenland and Finland, with the onset of the polar night, women completely stop ovulating. Conversely, in the spring, with the return of a large light period, the activity of the ovaries is significantly activated. This is proved by the fact that more twins are born in these countries than anywhere else in the world. Moreover, not only in the polar countries, but in any other spring, women have a dramatically increased chance of becoming pregnant. Israeli scientists have come to this conclusion by re-examining more than 600 cases of infertility treatment.

In winter, we sleep much more than in summer. And this is also due to sunlight. In a study of the functions of the pineal gland in the human body, scientists have found that this small gland produces melatonin, which plays an important role in maintaining human biorhythms. At night, the level of melatonin in the blood rises sharply. The pineal gland enlarges it under the influence of the hypothalamus, which transmits information about how much sunlight falls on the retina. Less light - more melatonin and, accordingly, lower activity, better sleep.

In 2009, a symposium was held in Rotterdam to study the effect of sunlight on humans. Representatives from 22 countries (scientists, doctors, architects, teachers) presented the results of their research in this area. The main conclusion was the unconditional influence of light on the physical, physiological and psychological state of people. So, American scientists have proved that the lack of sunlight in offices and stores directly affects the decrease in performance. Students living in apartments with windows to the north are usually more difficult to study. On the contrary, students in schools whose classes are on the sunny side learn the material much more successfully.

By the way, Israeli scientists in studies published in the journal JAMA, also argue that it is impossible to replace calcium obtained through sun exposure.
