Do you think sunbathing can make you taller?

Ever since My Love from the Star became a huge hit in the country, the market for Korean dramas in the country has been growing bigger and bigger. The female protagonists in Korean dramas are beautiful, and the male protagonists are not only handsome, but most of them also have a pair of long legs, so the term "long-legged Oppa" came into being. Yes, many boys hate themselves for not eating more and growing a few more centimeters taller. This will make you look more handsome. In order to grow taller, many people try every possible means and think of various ways to grow taller. Now someone asks if sunbathing can help you grow taller.

Sunbathing helps the synthesis of vitamin D. If the skin is exposed to ultraviolet rays in the sun, many dehydrocholesterols contained in the epidermis and dermis will produce photochemical reactions and form previtamin D3. Once previtamin D3 is formed in the skin, it will slowly convert into vitamin D3 at low temperature. This process takes at least 3 days to complete. Vitamin D is converted into an active form in the liver and kidneys and passively transported to the intestines, bones and kidneys, where it works together with parathyroid hormone to maintain blood calcium levels. When the blood calcium level is low, it can promote the synthesis of calcium-binding protein in the small intestine, thereby increasing calcium and phosphorus absorption. It can also promote calcium reabsorption in the renal tubules and mobilize calcium and phosphorus from the bones. When the blood calcium level is too high, it can stimulate the parathyroid gland to produce calcitonin, prevent calcium mobilization from the bones, and increase the excretion of calcium and phosphorus in the urine. So people will grow taller by basking in the sun, but it should not be done for a long time.

But unscientific sun exposure can also cause damage to the body. There are two times of the day that are best for sunbathing. The first period is from 6:00 to 10:00 in the morning. At this time, infrared rays are at their peak and ultraviolet rays are at their low point, making people feel warm and soft, which can activate blood stasis. The second period is from 4 to 5 p.m., when the a beam of ultraviolet light prevails, which can promote the absorption of calcium and phosphorus in the intestines, help strengthen the body and promote normal bone calcification. No matter what season it is, it is best not to stay in the sun for a long time between 10 am and 4 pm, especially between 12 noon and 4 pm, because at this time the ultraviolet rays in the sunlight are dominated by R beams and B beams, which can cause damage to the skin. In addition, from a quantitative perspective, insisting on sunbathing for at least 30-60 minutes a day can balance yin and yang. When sunbathing, it is best to wear red clothes, white clothes are the next best choice, and black clothes are taboo.

After reading the above explanation about whether sunbathing can help you grow taller, I believe that those of you who want to grow a few centimeters taller will be secretly happy, knowing that you have found a new secret to grow taller. Indeed, according to the above explanation, we can realize that sunbathing can promote our body's absorption of calcium. We all know that calcium is an important element to promote bone development. Therefore, sunbathing can theoretically help you grow taller, but we still need to pay attention to some issues.
