缺維生素D易感冒 多曬太陽 【12:25】
〔中央社〕1名46歲男性平常待室內工作，只要天冷或親友感冒，就一定感染。醫師表示，抽血檢查發現患者缺乏對抗感冒病毒的維生素D，建議多曬太陽補充。
榮新診所副院長何一成在記者會表示，收治1名46歲男性，因工作關係早出晚歸，假日也很少從事戶外活動，很少曬太陽，因此經常生病。只要天冷，或周遭有親友感冒，就一定被傳染，甚至1個月感冒2次。
何一成說，經進一步檢查及抽血檢驗發現，這名男性雖沒有重大疾病，卻有缺乏維生素D的情形。他解釋，維生素D對呼吸道黏膜防禦能力扮演重要角色；維生素D足夠，病毒較不易進入黏膜，且維生素D對人體免疫細胞殺死病毒或產生抗體殺死病毒，也很有幫助。
哪些族群容易缺乏維生素D？何一成說，很少曬太陽、肥胖者、皮膚較黑者、較少吃含維生素D的食物如魚肉、蛋黃、菇類、乳製品者或年紀較大者，都是可能容易缺乏維生素D的族群。
何一成建議，每天曬太陽10分鐘，讓身體自行合成維生素D，並適量攝取含有維生素D的食物如魚肉、蛋黃、菇類、乳製品。
不過，何一成表示，容易感冒的原因有很多，有慢性疾病或抵抗力較弱、飲食不均衡，營養素不足、缺乏休息，睡眠不足、情緒緊張，無適當的運動等，都是罹患感冒的因素。
若發現感冒，最好由醫師進一步檢查咽喉、鼻子、眼睛、胸部、腹部，有需要時做X光或血液檢查，才能給予適合藥物及治療建議。





有其他的論文可以以證明嗎

Lack of vitamin D synthesis is a possible explanation for high rates of influenza infection during winter;[108] however, see flu season for the factors apart from vitamin D that are also hypothesized to influence rates of infection during winter.[109] For viral infections, other implicated factors include low relative humidities produced by indoor heating and cold temperatures that favor virus spread during winter.[110]
