1. Do not bask through the glass
The ultraviolet transmittance of the glass is less than 50%, and the effect of the sun on the glass is likely to be discounted.
2. Do not wear white clothes in the sun
White clothes will reflect ultraviolet on the face or bare arms, so that the skin is injured, while the long wave of red clothing can quickly "eat" a very strong UVA. Don't wear a hat for advice, and you can wear sunglasses if you are afraid of blinding sunshine.
3. Drink more water in the sun
You should drink plenty of water after basking, eat more fruits and vegetables, it can inhibit the generation of melanin in a certain extent.
