Question

After a day at the beach, I came home with my skin red as if scalded by boiling water, with a burning sensation. Even lying in bed to sleep is uncomfortable. Besides sunscreen, are there any simple ways to relieve this pain?

Answer

There are two periods during the day that are most suitable for sunbathing. One is between 6 and 10 AM when infrared rays dominate and ultraviolet rays are low, making the sun feel warm and gentle, promoting blood circulation. The other is at 4:05 PM when ultraviolet α-rays are prevalent, which promotes the absorption of calcium and phosphorus in the intestines, producing vitamin D, and is beneficial for enhancing blood circulation and promoting normal bone calcification. Regardless of the season, it is not suitable to sunbathe for long periods between 10 AM and 4 PM. If there’s a reason to run in the sun, it’s best to take protective measures such as applying sunscreen, wearing a hat, and using an umbrella because the sun’s energy is strongest at this time, and it’s very easy to damage the skin.
