The king of summer is said to have amazing vitamin D production.
Negroids are black because they have a high level of melanin, which protects them from ultraviolet rays.
On the other hand, Caucasians are white because their pigment is thinner, making them more susceptible to absorbing ultraviolet light.
Modern humans, Homo sapiens, have become hairier over the course of evolution, and this has resulted in different skin colors depending on the level of ultraviolet light in the area where they live.
Exposure to UV rays beyond the skin's tolerance level can be harmful, causing spots and other problems. However, if you don't get enough UV rays, your body can't synthesize vitamin D.
The main role of D is to promote intestinal absorption of calcium, phosphorus, magnesium, etc. and to regulate blood calcium levels.
Without D, bones become brittle...or rather, bones cannot be formed.
People in the past could not survive without being exposed to ultraviolet rays from the sun .
...
My hometown, Akita, is said to have many beautiful women.
Why? Because it has the lowest annual amount of UV rays in Japan.
As a result, on average, Akita women are the fairest-skinned in Japan, and at the same time, they are also the prefecture's best at "hiding their seven flaws."
Second place goes to Toyama, and third place to Ishikawa. Next are Niigata, Yamagata, and the Tsugaru region of Aomori ( on the Sea of Japan side).
In fact, in contrast to the Pacific Ocean side of cities like Sendai, Mito, and Nagoya, where the sun shines brightly even in winter , the Sea of Japan side of northern Japan experiences a gloomy, leaden winter and is often cloudy throughout the year.
It's true that there are many beautiful women on the Sea of Japan side (or so it seems). They have fair skin, so even before you consider their facial features, you can tell that they are beautiful.
In fact, foundation doesn't sell very well in these areas .
...
UV protection is essential for beauty, so women must take care of their skin with UV protection.
However, the more we do this, the more unhealthy it becomes. This is because humans cannot obtain the ultraviolet rays they have absorbed in adequate amounts by mutating their skin color, and they are unable to synthesize D.
However, in the summer, about 30 minutes of sun exposure ( through glass to block UV rays) is enough to synthesize the necessary D.
If you don't leave the house, or even if you do go out, it's completely off-limits, and the chances of you falling and breaking a bone and ending up looking like a gyaru but frail increase.
Why is that?
Calcium and phosphorus absorbed from the intestines by D are converted into calcium phosphate and stored in the bones. ( Magnesium is responsible for forming bones and maintaining their strength.)
Osteoclasts dissolve calcium from bones and release it into the bloodstream, where cells use it to make muscles contract and the heart beat.
In addition, synapses, the joints of nerves, obtain calcium to fire neurotransmitters, allowing the brain and body to function.
However, if you are deficient in D, the calcium that you have taken in to form bones and the magnesium that forms bones will not be properly absorbed.
As a result, only enough bone is dissolved to meet the needs of nerves and muscles, but there is a lack of material to form new bone.
This is the mechanism behind osteoporosis, which causes bones to become porous at a young age.
Apparently, there are many gals whose bone density is on par with that of a woman over 70 years old.
Furthermore, he doesn't eat properly because he's worried about getting fat.
That's why gals are lacking in calories compared to people during the black market era in 1946 .
So what should we do?
Would you rather have the beauty of slender, snow-white skin or the health of a deep, tan?
Life is an exchange of equal value. If you want to gain something, you have to give up something.

The reason why Dad was feeling depressed while staying at home due to the coronavirus wasn't because he couldn't go out at night... but because there was no sun.
The reason why my mom was depressed was because that guy was always by her side lol
Well, when both you and your spouse are feeling down, it's a good idea to hold hands and go out under the sun together.
Sunlight not only releases vitamin D, but also stimulates the secretion of the yellow hormone of happiness, serotonin, through the retina. The amino acid tryptophan is converted into serotonin by the action of vitamin B6.
Huh?
Under the sun, our love, which used to feel like an obligation and an act, might return to its natural state, just like when you and I first met lol
A dad starved for love. Try giving a mom who has fed her baby plenty of amino acids and B6 beforehand a shot of the sun!
Dad, transformed into the "King of Summer," casts a magic spell there.
Yo! Let's be reborn under the sun, burn it down, Motto Motto!
Yo! Bye-bye to the blue sky for all your troubles!
Sufficient sunlight stimulates the wife's hypothalamus.
Happy hormones, squelch, squelch!
I think it's a great idea. I'll do it as soon as I get back to Japan! Under the sun~ ♫
...That's right.
"At that time, my father was painfully desperate to win back my mother's love, which I had stolen from him ."
Don't make such remarks as an adult, son lol
In another 35 years, you 'll surely follow the same path as me! Under the sun~♪
