For people who like sunbathing but are worried about ultraviolet rays will damage your skin, give you spots and wrinkles, and may cause skin cancer.
If your Japanese, you should definitely sunbath!
Although sunbathing in the summer sunlight is sometimes bad for you, sunbathing on a daily basis is healthy for you. Not enough sunbathing will weaken many parts of your body.
This article will introduce the reasons why sunbathing is so important for the body.
Why sunbathing makes your skin healthy
- Are ultraviolet rays an enemy?
- How long should you sunbath?
- Why sunbathing is good for you
１．Are ultraviolet rays an enemy?
First of all, the idea that ultraviolet rays are not good for you was created and brought to Japan by western culture.
Japanese people tend to admire western ideas and customs without doubt. The thought that ” westerners are more superior” is still often present in Japanese culture, which I strongly disagree to.
The main reason for this brainwashed idea is due to commercials.
For a certain region, there is always a culture and shape that fits the most. Japan has its own culture and beauty that fits the country’s land and climate, and understanding it is crucial to live a fulfilled life.
The idea that ultraviolet rays are not good for you is aimed at western and australian people, who have less melanin, weaker eyes and skin, and a higher risk of skin cancer compared to Japanese people.
Western countries and Australia also have less humidity compared to Japan, making the effects of ultraviolet rays more powerful.
Compared to that, since Japan has higher humidity and asian people have stronger skin, it is not neccesarry to worry so much about ultraviolet rays as they say in commercials.
Especially in northern Japan where sunlight is scarce, frequent sunbathing is recomended.
２． How long should you sunbath?
A research team from The National Institute for Environmental Studies and Tokyo Kasei University created data that shows how long you should sunbath to keep your health.
For the body to create the daily required amount of vitamin D of an adult, the time required to sunbath on a sunny December day (which has the least amount of ultraviolet rays) is :
- Naha City 14 minutes
- Tsukuba City 41 minutes
- Sapporo City 139 minutes
It may seem like a small number, but thinking about it, do you actually stay under the sun for 30 minutes a day? Depending on your life style, it may actually be quite difficult.
３．Why sunbathing is good for you
It prevents bone aging
A widely known illness concerning the aging of bones is “Osteoporosis”. When you fall victim to osteoporosis, it is said that in the worst case you may even break a bone when you sneeze.
To prevent osteoporosis, calcium is crucial. And to absorb calcium, vitamin D, which can only be created by absorbing sunlight, is necessary.
When ultraviolet rays contact the skin, cholesterol inside the blood turns into vitamin D (a double good effect!).
Lacking vitamin D makes your bones and teeth weak, and makes you become tired easily.
Although it differs according to region, it is recommended to sunbath one hour a day in winter, and 15 to 30 minutes in the summer.
Adjust your biological clock
There is an illness that has become a problem in modern society, called “SE depression”. SE is an abbreviation for system engineer.
Although SE depression is a type of depression, it is not created from stress due to human relationships or trouble at work, but the lack of sunbathing.
Adding to symptoms of depression such as the lack of motivation, SE depression creates irritation, discomfort, waking up in the middle of the night, and makes you not interested in anything.
The biological clock of a human is actually about 24 hours and 45 minutes, which means a gap is eventually created between the actual time and your biological clock. But feeling the sunshine upon you when you wake up helps reset the biological clock, helping it to align with the actual time.
But not sunbathing all day long or not exercising makes your biological clock keep going off time, eventually creating the risk of SE depression.
It is scientifically proven that sunbathing is a very useful cure for SE depression and depression.
Although Japanese people have strong skin, sunbathing too much especially on purpose during mid summer time can be dangerous. Ultraviolet rays are very powerful, and as sudden sunburn is nearly the same as a burn injury, it can cause spot, and skins cancer. As always avoiding sunlight to try to have beautiful white caucasian skin is dangerous, sunbathing extremely to try to become dark like african americans is also dangerous. Stay with who you really are, and sunbathe just enough so you can live healthy.
