Away from the hustle and bustle of the city, a blue head, lazily lying on the soft beach, enjoying the sun’s bath; for men, there is also a fun thing, is to steal a glance in a bikini body hot beauty; according to common sense, all the beauty and comfort, should reduce the risk of individual suicide, but this literature suggests that sunbathing will increase the risk of suicide, how can it be elevated? Tanning is a method of using sunlight to exercise or prevent chronic diseases, mainly by allowing sunlight to hit the human skin, causing a series of physical and chemical reactions to achieve fitness and cure, mentioning tanning, we are not unfamiliar with it. In the fast-paced, high-intensity, high-stress work environment, sunbathing is actually a good way to relax, although the time and place are not allowed, but leisure time, activities, out in the sun is also a good choice. However, a study in the journal JAMA Psychiatry showed that sunbathing may increase the risk of suicide. Suicidal behavior has been shown to be influenced by daylight and the seasons. However, other meteorological factors brought about by the seasons and seasonal rhythms in social behavior may also contribute to fluctuations in suicide rates. This study, conducted by Dr. Benjamin Vyssoki of the Medical University of Vienna, Department of Psychiatry and Psychotherapeutic Medicine, Austria, analyzed 69,462 suicide cases in Austria between January 1, 1970 and May 6, 2010. 86 representative meteorological observatories recorded their average daylight hours. After eliminating differences in daylight and suicide incidence due to seasonal changes, the results of the study showed that daylight hours were significantly associated with suicide frequency, with 1-10 days of daylight hours likely to promote suicidal behavior and 14-60 days of daylight hours having a lower incidence of suicide. According to Dr. Matthaeus Willeit from the University of Vienna, suicide is the result of many factors, and sunlight is only one of many risk factors. Although we need to take sunlight into account, the study does not expect people to avoid sunlight as a result. This study does not provide constructive treatment advice for patients, and there is still a long way to go in studying the relationship between sunlight and suicide rates.
