Use milk. As a compress.
I read this just recently in Prevention magazine.Milk is the beverage of choice for relieving the discomfort of sunburn. Apply cool, not cold, milk with a clean cloth or gauze to your skin. The coolness soothes the initial heat felt by the skin and the milk will create a protein film that helps ease the discomfort.
FYI: also apply sunscreen to the ears, back of neck, feet/toes, back of knees, etc.
Some people get skin cancer, in between their toes.
1 hour in the sun is a long time.
For clothing, as we do here in Hawaii, wear a "rash guard" top... ie: the kind used by Surfers etc. It gives sun protection and sunburn protection.
Kids here commonly wear these tops to the beach or out in the sun. Adults too.
Places like Amazon, LL Bean etc., has these tops.
Here is a link for example:
