爲什麼曬太陽有益健康?
Hurray for warm days and long, summer evenings! The sun is good for us - in fact, researchers at Sweden's Karolinska Institute say that avoiding the sun can be as bad for you as smoking. Here's why it's good to spend time in the sunshine...
致陽光明媚的日子！致漫長的夏夜！太陽有益身體健康--事實上，瑞典卡羅林斯卡研究所的研究員表示，避免與陽光接觸可能會帶來與吸菸一樣的影響。那爲什麼曬太陽有益身體健康呢？
1. It helps you start the day
1. 幫助你開啓美好一天
Being woken up gradually by the natural light of the sun improves energy and mood during the day because it switches off melatonin, which stimulates sleep. You're less likely to get that groggy, half-asleep feeling you suffer during the dark mornings of winter months. Sleep with your curtains open to wake naturally, say sleep experts.
被太陽光自然叫醒會讓你白天充滿精神、心情倍兒好！因爲陽光會使褪黑激素（刺激睡眠）停止分泌。冬季的清晨灰濛濛的，你會感到昏昏欲睡，有種半睡半醒的感覺，但夏季時分就不會擔心這些情況。睡眠專家說，睡覺的時候別拉窗簾有助於自然醒來。
2. Your skin can benefit
2. 皮膚會從中受益
"In some people sun exposure can improve skin conditions such as acne, eczema and psoriasis," says Dr Ross Perry, GP and medical director of CosmedicsUK (). "Just be careful not to overdo it and never risk burning."
"對某些人而言，曬太陽會改善他們的皮膚狀況，比如痘痘、溼疹和牛皮癬，"CosmedicsUK的全科醫生、醫學主任羅斯·佩裏博士說道。"但別一直暴曬，也別曬傷。"
3. You'll feel happier
3. 你會更快樂
It's no coincidence that we all feel better when the sun is shining, says Emma Derbyshire, public health nutritionist and spokeswoman for Health and Food Supplements Information Service. Exposure to sunlight is also linked to serotonin production in the brain, promoting positivity. "A pilot trial found that safe sun exposure can actually help alleviate depressive symptoms, particularly in those who are vitamin D deficient," says Emma.
陽光明媚時，人們的心情會變好，這並非巧合，公共衛生營養師、健康與食品補充信息服務機構的發言人Emma Derbyshire說道。曬太陽也與大腦中血清素的生成有關，促進大腦積極思考。"一項試點試驗發現：安全的曬太陽實則有助於緩解抑鬱症狀，尤其是缺乏維生素D的患者的症狀。"
4. It may help you stay in trim
4. 有助於保持苗條身材
"Good vitamin D levels have also been linked to reduced levels of body fat," says Emma. According to studies by the universities of Southampton and Edinburgh, ultraviolet radiation may suppress the development of obesity and type-2 diabetes.
"攝入足夠的維生素D與體脂含量降低有關，"Emma說道。南安普頓大學和愛丁堡大學的研究表示，紫外線輻射或能抑制肥胖和2型糖尿病的發展。
5. It's good for your heart
5. 有利於心臟健康
People are more likely to die from heart disease in the winter than in the summer. According to researchers from Copenhagen University Hospital, those with the lowest levels of vitamin D are 81% more likely to die from heart disease compared to those with the highest levels of the vitamin. Sun exposure cuts risk of heart attack and stroke by reducing blood pressure, according to research.
冬季死於心臟病的人數要比夏季多。哥本哈根大學醫院的研究人員表示，體內維生素D水平最低的人死於心臟病的可能性比體內維生素D含量最高的人高81％。研究表明，曬太陽可以通過降低血壓來降低心臟病發作和中風的風險。
