In the hot summer, ultraviolet rays have become a major concern for everyone. There are many hazards of ultraviolet rays, first of all affecting our face value. Everyone knows that when you go out for an hour or two at noon, your skin will be sunburned, with erythema or pigmented sunburn, and sometimes peeling.
A longer time will cause the skin color to change, the skin to become bronze or black, and panda arms appear. And no matter how many anti-aging measures we do, it can’t compare with the effect of ultraviolet light aging. Only a light exposure will make our skin lose its elasticity and age quickly.
Even if it only affects the face value, ultraviolet rays can also cause a variety of diseases, such as making our vaccines ineffective, producing non-melanoma skin cancer, solar keratosis, keratitis, malignant melanoma, and even The risk of blindness from secondary cataracts is really a big killer of health.
Because of this, everyone strives to live in a house where the door does not go out of the way. Even if they go out occasionally, they will apply thick sunscreen. Sunscreen can effectively block ultraviolet rays, which can be said to save us. But it also brings new problems, such as insufficient vitamin D content.
Everyone knows that although ultraviolet rays are abhorrent, they are also beneficial. First, they can sterilize and kill insects, such as mites on our faces, and secondly, they can also react with the skin to produce vitamin D. And this process is irreplaceable, which means that we can not replace the production of vitamin D through food or other methods. The most important thing is that our body does need this ingredient. Many experiments have proved that vitamin D produced by light can effectively reduce the incidence of osteoporosis in the elderly.
So in the summer, we are faced with a dilemma. Should we apply sunscreen? If painted, although this can effectively reduce the prevalence of skin cancer, melanoma, and keratosis, it also brings new risks due to too little light, such as insufficient vitamin D synthesis, which can induce osteoporosis. So what should I do to ensure that my body’s bone density and bone content are normal without causing skin diseases?
Fortunately, many people have carried out relevant research and put forward a very impressive method for us, mainly including the following points.
- No sunscreen in winter
For some places, vitamin D deficiency is seasonal and mainly occurs in winter. At this time, the sun is not too strong, so you don’t need to apply sunscreen when you go out. For this reason, we can make full use of the winter time, reject sunscreen, enjoy ultraviolet rays, and let vitamin D be fully produced.
- Summer morning and evening sun
During the summer noon, the ultraviolet rays are very strong. Naturally, sun protection is needed during this period. However, in the morning or evening, the ultraviolet rays are relatively weak. We can go out for a walk and sunbathe. It usually takes about ten minutes. In addition, you can also directly expose your arms, legs, etc. to the sun to fully promote the skin’s reaction with ultraviolet rays and allow vitamin D to be synthesized in large quantities.
- Eat more foods rich in vitamin D
Although vitamin D produced by the reaction of ultraviolet rays with the skin is irreplaceable, eating more foods rich in vitamin D can also effectively prevent osteoporosis such as decreased bone mass and decreased bone density. So we can add these foods properly and drink calcium milk to make ourselves healthier.
Finally, I hope everyone can learn to balance and live a healthy and beautiful life.
