How to protect yourself from the sun when swimming in summer and how to repair after sun exposure

The sun's ultraviolet rays are strongest (and can cause the most damage) between 10 a.m. and 3 p.m. The best time to swim is after 4pm. For those who are particularly afraid of getting tanned but still like swimming, it is recommended to go to an indoor swimming pool.

Be prepared for sun protection before swimming. It is best to apply some oily sunscreen to avoid the sunscreen being washed away by long swimming. Of course, you still need to reapply sunscreen within two or three hours. It is recommended to protect your skin with a waterproof sunscreen with an SPF (sun protection factor) of 30 or above. To ensure the best effect, apply every half hour to one hour.

Strong ultraviolet rays will cause a large amount of moisture loss from the keratin in the hair. Wearing a swimming cap is the most direct and effective way. Even without a swimming cap, you can apply a leave-in hair serum with sun protection directly to your hair.

Don’t think that you don’t need sunscreen on cloudy days. There is also ultraviolet light in the sun on cloudy days. It’s not that it disappears just because you can’t see it. After being reflected by water, it becomes very strong and your skin will still get sunburned. So you need to wear sunscreen as long as your skin is exposed to the sun.
