How much SPF should I use for sun protection in this weather?

If you stay indoors, don't go out. SPF26 is enough. If you are outdoors, choose SPF30-36. If you are outdoors for a long time, choose SPF50. Don't wear it once every eight hours, and wear it half an hour before going out. It is best to choose products that are sweat-proof rather than waterproof.
