Fang Ye looked at the barrage of comments and was amused by the netizens' jokes. He then explained, "That's right, many animals including cats and dogs love to bask in the sun. Just look at the people sunbathing on the beach and you'll understand.
As for the reason, first of all, our bodies need sunlight. You all have heard the saying 'sunbathing for calcium,' haven't you? Actually, that phrase isn't accurate. More precisely, the ultraviolet rays from the sun can promote the synthesis of vitamin D, and vitamin D can facilitate the absorption of calcium and phosphorus, affecting bone metabolism.
Keep in mind that only 10–20% of the vitamin D in the human body comes from food; the rest is synthesized through exposure to ultraviolet rays. Therefore, I suggest everyone take the opportunity to get out of the house and bask in the sun. Sunbathing inside the house is useless, oh, since glass can absorb most of the ultraviolet rays."
