This study intended to verify that sunshine has a positive effect on promoting health based on precedent researches and find the right exposure methods to sunshine in order to promote health in island residents through the research results of SWOT analysis.
For this, the problems that may arise with insufficient or excessive exposure to sunlight and their countermeasures shall be analyzed respectively by using the SWOT technique.
The problems that may arise with insufficient exposure to sunlight as indicated in the SWOT analysis and there countermeasures are as follows; 1) Problems that may arise with insufficient exposure to sunshine: First, development of cancer due to vitamin D deficiency. Second, development of rickets due to vitamin D deficiency. Third, development of melancholia and deteriorated cognitive function due to vitamin D deficiency. 2) Countermeasures against the problems that may arise with insufficient exposure to sunshine: First, recommending adolescents with insufficient exposure to sunshine to take natural vitamin D (beef or pork liver, blue-scaled oily fish, eggs, pyogo mushrooms) and vitamin D nutritional supplements. Second, recommending those who have vitamin D deficiency to take food with vitamin D (salmon, sardines) based on big data analysis.
The following are the problems that may arise with excessive exposure to sunshine and their countermeasures analyzed by using SWOT analysis; 1) The problems that may arise with excessive exposure to sunshine: The UV rays may benefit the human body but also harm the body to cause skin damage and skin aging. UVA causes skin aging such as discoloration, freckles, and wrinkles and UVB, skin cancer such as epithelial cell carcinoma and base cell carcinoma. 2) Countermeasures against the problems that may arise with excessive exposure to sunshine: First, recommending those who have sunshine allergy to avoid sunshine with UV sunscreen. Second, to be careful when using the cosmetics containing oil. Third, to take precautions against the sunshine when using a specific medicine.
Through the research results of the SWOT analysis, two methods to effectively be exposed to the sunshine were suggested as follows; First, which part of the body should be exposed to the sunshine and for how long? According to the ��Law of Nine,�� the best way to expose oneself to sunshine was to expose about half of the arms and legs (about 54% of the body). Second, how much exposure to the sunshine in a day according to season should one take? It was recommended to have adequate sunshine exposure for between 4��11 months with the time window of 10 a.m. to 2 p.m. being optimum, and a total exposure of 30 minutes to the sun in a day.
Four recommendations for the right exposure methods to sunshine in conclusion were suggested as follows; First, Taking a 30-minutes sunbathing session at least once a week to promote health is the minimum exposure to the sunshine and must be practiced accordingly, and it was recommend to wear short clothes when taking a walk. Second, sunscreen was not recommended for full exposure but when it is applied, choose the one with SPF 10-15 or less, and it was recommended to apply an appropriate amount of UV sunscreen when taking a walk. Third, it was recommended to open windows to expose oneself to the sunshine because it is not effective to expose one��s body to sunshine from behind a window. Fourth, it was recommended to have adequate sunshine exposure as the sunshine, which is generally good for health, may cause negative effects when the body is overexposed.
