What are the benefits of sunbathing? Health is the most influential factor to a person. Because health is the foundation of life, the most important thing for us is health. Don't neglect our health. Without health, there is nothing. What are the benefits of sharing sunshine below?
What are the benefits of sunbathing? 1 Sunbathing can supplement vitamin D. The main source of vitamin D in human body is sunlight transformation, and the intake of vitamin D in food is very small. Vitamin D can help people absorb calcium and phosphorus.
Sunbathing can enhance human immunity, improve disease prevention and resistance, and reduce the occurrence of diseases. Nowadays, many people like to drink cold drinks, blow air conditioners, live in buildings, seldom go out, exercise less, have great work pressure, and their bodies are prone to soreness and itching. Therefore, it is very reasonable to bask in the sun regularly, supplement the yang in the body and improve the body's disease resistance. Sunbathing can regulate the activity of renin-angiotensin system in the body to regulate blood pressure and reduce the occurrence of respiratory diseases such as colds.
Sunbathing can prevent myopia. Sunlight can stimulate the human body to secrete dopamine, inhibit the growth of eye axis, and effectively prevent and control myopia.
Sunbathing can make you happier. Sunbathing can speed up your heart rate and make you feel happy. Sunbathing can increase the secretion level of serotonin, adrenaline, thyroxine and gonad, accelerate metabolism, promote blood circulation, make people feel comfortable, improve mood, improve depression and make people feel happy.
Everything can't grow without the sun. Some people say that sunbathing is the engine of human happiness and the magic medicine of human beauty. However, exposure to strong sunlight for a long time is easy to burn the skin, and even through clothes, there are precautions in the sun.
Pay attention to the time period of sunbathing, 6: 00 am 6:00- 10/0 and 4: 00 pm-5: 00 pm. The ultraviolet intensity is weak during these two time periods, and the skin is not easy to get sunburned. Sunbathing lasts about 30 minutes every day, and different ages absorb different sunlight.
Do not bask in the sun through glass, clothes, sunscreen, etc. This kind of sunlight, which can transform the human body into vitamin D, has weak penetration and cannot bask in the sun through glass, clothes and so on. So you should expose your skin and get full exposure to the sun.
What are the benefits of sunbathing? Sunbathing can prevent osteoporosis.
According to the People's Daily, there are many people with low bone mass in China. The low bone mass of people over 50 years old can reach 46.4%, and more than 70 million people suffer from severe osteoporosis. Insufficient sunlight is an important cause of osteoporosis. Life Times also indicated that 70% of people in China have insufficient sunlight.
Then why can receiving sunlight prevent osteoporosis?
When it comes to sun exposure, it can prevent osteoporosis, mainly because ultraviolet rays in the sun can convert substances on the surface of our skin into vitamin D.
As an important nutrient, vitamin D plays an important role in the absorption of calcium.
When vitamin D is sufficient in the body, on the one hand, it can promote the absorption of calcium, on the other hand, it can also help the deposition of calcium in bones, regulate the nerves of skeletal muscles, promote the formation of osteoblasts, make bones stronger and stronger, and achieve the purpose of improving and preventing osteoporosis.
After reaching the peak at the age of 30, our bone mass began to drop significantly. Low bone mass is common due to lack of exercise, unbalanced diet and bad living habits. Once you get older, your bones become looser and looser, so osteoporosis appears. Faced with this bone problem, many people will think of calcium supplementation.
Studies have proved that the absorption of calcium can not be separated from vitamin D, and vitamin D can not replace sun exposure. This is because only 10% of vitamin D in our body comes from food, and the rest comes from the transformation of sunlight to the skin. Therefore, it is advisable to supplement vitamin D by receiving sunlight, which is a simple and affordable method to promote the absorption of calcium by the human body, thus preventing osteoporosis.
Therefore, for middle-aged and old friends and young people who often sit in offices and lack exercise, sunbathing can strengthen their bones and prevent and stay away from osteoporosis.
Promote children's intellectual development and delay the mental decline of the elderly.
Regular sunbathing also plays an important role in promoting children's intellectual development and delaying the mental decline of the elderly (from New Countryside magazine). Ultraviolet B in sunlight can promote the production of vitamin D, which can be converted into uric acid through histidine, thus increasing the level of glutamic acid in the brain.
On the one hand, the increase of glutamate can cause cortical movement of the brain, on the other hand, it can increase the excitability of hippocampus. The cortical movement of the brain affects the level of our long-term memory and is very important for the storage of information. On the other hand, the hippocampus affects the ability to store and process information.
In addition, synaptic vesicles that affect information contact and transmission in the brain are also rich in glutamate. Increasing the content of glutamic acid by sunbathing is beneficial to improve the speed of transmitting information and the ability of storing information in the brain, and then it can increase its memory and reaction ability.
For children in the growth and development stage, more sunshine and outdoor exercise can not only supplement vitamins and calcium, but also prevent rickets. It can also improve the excitability of brain nerves, thus improving children's learning and information storage ability. It can be seen that regular sun exposure plays an important role in children with strong learning ability and strong interest in learning.
At the same time, it is also important to expose children to the sun, breathe fresh air and improve their perception. When children see, hear and feel the dribs and drabs of nature in outdoor sports, their understanding and perception ability is stronger than other children.
For elderly friends, the nervous system and intelligence will inevitably decline, but regular sun exposure of elderly friends can promote the synthesis of uric acid, thus delaying mental retardation and preventing Alzheimer's Harmo's disease.
Therefore, whether for children, old friends or young people, regular sun exposure plays an important role in brain and intelligence.
Longer life and healthier body.
Due to the accelerated pace of life and the change of working style, people's outdoor activities are decreasing, which naturally leads to a great reduction in the time spent in the sun.
British scholars studied 400,000 people. The results show that people who spend less time in the sun are more likely to feel depressed, while those who spend more time in the sun are less likely to have negative emotions such as depression and depression. This is because the secretion level of adrenaline and other secretion systems in human body will be improved under the irradiation of sunlight, and the secretion of these hormones plays an important role in improving bad mood.
I believe that if you have a positive attitude, you will be happy every day and your body will be healthier. Under the same conditions, your life will naturally be longer.
In addition, sunbathing can also improve immunity. Studies have proved that regular sun exposure helps to activate hydrogen peroxide in the body, thus keeping T cells of immune cells active, thus achieving the functions of sensing infection, disinfection and sterilization, and reducing the risk of cancer.
Yale University in the United States found through research that people who receive less sunlight are more likely to be infected with influenza virus than those who receive more sunlight. This is because frequent exposure to the sun makes the body have enough resistance, which can prevent colds well and greatly reduce the harm of influenza virus. It can be seen that accepting more sunlight can really enhance resistance and make you healthier.
In addition, regular sun exposure can reduce cardiovascular diseases to a certain extent, which is more conducive to good health. This is because the sun synthesizes vitamin D, which plays an important role in the prevention of hypertension and the health of blood vessels.
People who have the habit of sunbathing have a lower risk of heart disease and myocardial infarction (from British Medical Journal). Many studies also show that compared with sunny summer, the probability of myocardial infarction in winter is greater. Therefore, regular sun exposure is indeed more conducive to heart health and longevity.
Danish researchers have studied 4.4 million related people for 26 years and found that people who often receive sunlight live longer. People who have the habit of sunbathing and often take part in outdoor activities are healthier than those who stay at home or office for a long time.
How to sunbathe better and more accurately?
Since sunbathing has so many benefits, how can we sunbathe most correctly and effectively?
Pay attention to the time of sunbathing.
The time period for sunbathing is 6- 10 in the morning. The sun at this time has a certain temperature, but it is not particularly hot, which can promote metabolism and improve your resistance. In addition, you can also choose 4-5 pm. At this time, there are more A beams in the sun, which is conducive to the synthesis of vitamin D, and then better achieve the effect of calcium supplementation.
For those who are not sure about time, they can also use shadows to help them judge. When the shadow of the sun is long, this time is more suitable for outdoor activities. The length of the shadow in the sun is shorter than the height, which makes it easy to get sunburned. Going out for activities is not recommended.
Don't sunbathe through the glass.
Many people want to bask in the sun, but they don't want to go out or are afraid of sunburn, so they choose to bask in the sun through the glass. Although the glass looks transparent, this kind of transparent glass can still block ultraviolet rays.
Therefore, for sunbathing, sunbathing through transparent glass is not recommended. If you really want to achieve the effect of sunbathing, it is still recommended to go outdoors to receive the sun.
Be careful of getting sunburned when you are in the sun.
Although sunbathing has many benefits, everything has its limits, and so does sunbathing. If you stay in the sun for a long time, it is easy to cause skin damage.
It is best to keep the time of receiving sunlight for about 20 minutes a day, 3~5 days a week. It's best not to be exposed to the sun when the sun is strong. If you need to be exposed to the sun for a long time, remember to take sun protection measures.
In a word, sunbathing, as a healthy and cost-free health care method, can bring great benefits to our physical and mental health.
In fact, a healthy regimen is available for free. As long as we are willing to do it, we can promote our health without eating any health products.
What are the benefits of sunbathing? 3. Improve sleep.
Our sleep rhythm is influenced by factors such as light and hormone secretion. Sunlight can help us to establish a circadian rhythm, and it can also affect the secretion of melatonin in the body. Proper irradiation of Yangguan can restore melatonin secretion to the normal state of less during the day and more at night, which is helpful to improve daytime sleepiness and insomnia at night.
Regulating emotion
Our mood will be influenced by the environment. Sunbathing can change the temperature and brightness we feel, help to adjust our mood and improve our mood.
Vitamin d supplement
Vitamin D in the diet is actually limited, and most people are in a state of vitamin D deficiency. Sunbathing is the main way to get vitamin D naturally. UVB in sunlight can promote the conversion of 7- dehydrocholesterol into vitamin D3 in our body.
bring down the blood pressure
Under the promotion of sunlight and ultraviolet rays, nitric oxide in skin can be absorbed by blood, which has the functions of lowering blood pressure and relaxing blood vessels. Vitamin D produced by sunlight also has the function of maintaining cardiovascular function.
Sunbathing has many benefits to the human body, but we also need to pay attention to the following points:
Avoid exposure to the sun
Although sunshine is good, it can also bring high temperature dehydration and skin damage. It is best to choose sunny morning or afternoon, which is relatively mild.
Avoid prolonged exposure.
Sunbathing lasts 15 minutes to 30 minutes at a time, and too long time may lead to sunburn.
Expose the skin as much as possible
Sunlight will be blocked by obstacles such as clothes and glass. When you think about the good effect of sunbathing, you should expose your skin to the sun as much as possible.
In fact, there is no need to deliberately bask in the sun. Getting into the habit of going out for a walk every day is the best way to get enough sunshine.
