Everything grows in the sun, as a study published a day ago at the Karolinska University School of Medicine in Sweden confirmed that women who often bask in the sun are more likely to be exposed to the sun than women who hide from the sun. The risk of cardiovascular disease, diabetes, multiple sclerosis and pulmonary artery disease is lower. The study also found that “sunless” has become the fourth typical health habit after smoking, obesity and inactivity.
Three worries are blocking the sun.
The study reportedly tracked nearly 30,000 women for 20 years. The researchers found that smokers who basked in the sun lived the same life span as non-smokers who hid from the sun. Smokers who had the longest exposure to the sun lived even 0.2or 2.1 years longer than non-smokers who hid from the sun. Research lead, Pell? Despite the limitations of the study, Dr LinderWest said, “No sun” and “smoking” could be linked as high risk factors for death.
“it’s a new idea, and many doctors probably don’t know so much about the sun. “Zhao Junying, director of the skin and venereal diseases section of Beijing Friendship Hospital, said. Shen Yanying, an expert at the China Center for Health Education, said she had visited many countries in Europe and the United States and found that local people were particularly fond of the sun. Running, playing and drinking coffee in the sun were everywhere, but not many people in China took the initiative to go outside to bask in the sun. The reason, experts say, is that the following three major concerns hinder people’s close contact with the sun.
The skin ages as soon as it is tanned. Zhao Junying said that dermatology advocates sunscreen because excessive sun exposure can easily lead to skin aging, but sunscreen is not without the sun at all. But some people go out wearing masks, umbrellas and sunscreen, which is a bit of an exaggeration. The rational approach is to suntan, but not to the sun.
I’m afraid of skin cancer. Jiang Wei, director of dermatology at Peking University’s third Hospital, pointed out that international studies have confirmed that prolonged sunlight exposure may cause skin tumors, but most Asians are III or IV type in Fitzpatrick skin classification. The incidence of skin tumors is lower than in Europe and the United States (mostly type I or II skin), so you don’t have to refuse to bask in the sun. However, when ultraviolet radiation is strong, it is necessary to use sunscreen products and take appropriate sunscreen measures.
You can’t get the sun out after eating photosensitive food. Photosensitive vegetables do exist, but only allergies or specific physique, may be due to improper consumption of dermatitis, and so on, others do not worry.
Not to be in the sun is particularly hurtful.
“the study confirms that the dangers of not basking in the sun are more serious than you think. Dr Pell argues that there is merit in calling “sunless” a fourth form of health abuse.
Osteoporosis. More sun is good for the human body to produce vitamin D, promote the absorption and utilization of calcium and phosphorus. Instead, it can lead to vitamin D deficiency, increasing the risk of osteoporosis.
Diabetes. A study by the National University of Malaga, Spain, found that low levels of vitamin D caused by inadequate sun exposure increased the risk of obesity and type 2 diabetes.
Depression. Too little exposure to the sun causes the brain to secrete more melatonin, exacerbating sleepiness and fatigue. It also inhibits the production of the brain’s “happiness hormone” 5-hydroxytryptamine, leading to depression. Clinically, seasonal depression due to shorter days and shorter nights and reduced sunshine is common.
Foreign studies have found that too little exposure to the sun also increases the risk of heart disease, cognitive impairment, erectile dysfunction, prostate cancer, schizophrenia and other diseases. And sunburn helps prevent many kinds of cancer and allergy, asthma, myopia, flu, rickets and other common diseases. A 26-year study of 4.4 million to 100-year-old Danes found that exposure to more sun significantly prolonged life expectancy, even in patients with skin cancer caused by excessive exposure, with an average life span six years longer than the average person.
Are you a “lack of sun”?
Do you need more sun? Answer the following questions first.
1. Do all round sunscreen every day, Wu is particularly strict? 2. Do you spend most of your day indoors? 3. Isn’t it sunny in the bedroom? 4. Would you prefer to stay at home on weekends? 5. Do you have osteoporosis? If you have more than three “yes” answers, go outside and get more sun. To be reminded, the sun to master the skills, not enough, too much is not good.
I get half an hour of sun every day. Shen Yanying points out that it is appropriate for adults to stay in the sun for 30 minutes or 1 hour a day; infants and children can be suitably shortened to 1530 minutes because of their delicate skin; and the ability of the elderly to synthesize and utilize vitamin D is reduced. Time can be extended properly, but not too long exposure.
Avoid UV peak time. Jiang Wei recommends keeping out of the sun from 10:00 to 4pm. In the year, late spring to early summer, UV is the strongest, especially should be noted.
Go out to the sun. Chao Chun-ying points out that through the sun through the glass, UV transmittance is insufficient, which is unfavorable for the body to synthesize vitamin D. it is best to go to an outdoor environment with better greening and fresh air. If meet strong wind wait for bad weather, can be basked in the sun near glass in the home, effect is stronger than do not bask.
Keep warm, but don’t wear a hat. Shen Yanying reminds, autumn and winter season temperature is low, go out to bask in the sun must do a good job to keep warm, but do not wear a hat. The old man who has cataract and other eye diseases can wear sunglasses in order to prevent blinding eyes.
Match the action with half the effort. “in the sun, in addition to the head, legs, back is also the focus. “Shen Yanying suggests, face to face with the sun, close your eyes, open your arms, palm toward the sun, your fingers slightly folded, imagine the sun sprinkling all over your body, cooperate with deep breathing, put down your arms when you feel tired, repeat this action for 15 minutes and rub your hands. Warm your face and take a walk.
Eat more fruits and vegetables after the sun. After basking in the sun, Jiang Wei suggests, drink green tea and eat fruits and vegetables rich in vitamin C to help you care for your skin.
