Excessive sun protection can harm your body

　　Beauties! Please don’t let the sunshine down

　　Animals cannot survive without sunlight, air and moisture (it doesn’t matter for some strange species), don’t forget the beautiful things female They are all animals, and they cannot live without this third child. However, as the temperature rises, if you go to the street and take a look, even if the weather is a bit gloomy, you can find a few brightly colored parasols. Ladies actually regard the sun as

　　After careful analysis, there are no more than two reasons: one is the fear of tanning one's fair skin.； Those with a little knowledge of health care may be afraid skin Cancer, in addition, there are a small number of people who are allergic to sunlight and are afraid of getting solar dermatitis. It goes without saying that you are afraid of allergies, but it is a bit unreasonable to be afraid of tanning. So what if you are extremely whitening? If you don't have a good body, no matter how beautiful, white or slim you are, you can only lie at home and feel sorry for yourself. Although not being exposed to the sun will not have such great magic power in the short term that makes people lose their good health, in the long run, if you refuse the caress of the sun, you will definitely lose the sun's love for you. So what kind of love does the sun have for us? As the saying goes, everything depends on sunlight to grow. We won’t go into this in detail. Let’s talk about the benefits of direct exposure to sunlight:

　　Benefits 1. Ultraviolet rays in sunlight can kill a large number of pathogenic bacteria on the surface of the human body and have a direct cleaning effect on the skin.；

　　Benefits 2. Sunlight can affect the secretion of melatonin in the human body and directly affect your mood. You may think that your mood is better when the sun is shining. You must know that there is almost no sunlight in Iceland in winter, causing many people to suffer from depression. Now there is a market that artificially simulates sunlight exposure for citizens every day to prevent depression, which shows the importance of sunlight.

　　Benefit 3. Human skin contains a type of cholesterol called 7-dehydrocholesterol. This cholesterol can be converted into vitamin D3 under ultraviolet irradiation in the sun. Vitamin D is an important vitamin for the human body and is related to the body's absorption and regulation of minerals such as calcium and phosphorus. Once deficient, it will cause calcium and phosphorus absorption disorders. Child Rickets are prone to occur, such as chicken breasts, X-shaped legs, and O-shaped legs； rickets in adults ； Elderly people with symptoms of osteoporosis are prone to fractures.

　　Of course, this does not mean that in order to prevent osteoporosis, you can wait until you get older and spend more time in the sun. The dark spots will not matter at that time. This is not the case. elderly Osteoporosis will appear sooner or later, but if you exercise enough and have good nutrition (such as sufficient vitamin D, calcium, phosphorus and other minerals) when you are young, the calcium contained in the bones will be relatively sufficient. At the same age in old age, the calcium contained in the bones will be more than that of peers, then she will develop osteoporosis later and the possibility of fractures will be relatively less. It can be seen that this is a long-term investment process, not just a matter of three days. When you are really old, your absorption will be poor and you will exercise less. No matter how good your nutrition is, the supplemented nutrients may not be well absorbed. What's more, the amount of vitamin D contained in food is generally very small.

The benefits are too numerous for us to list them all here.
