What is a natural remedy for a sun burn that stops the redness and burning sensation?

Sunburn severity?: If you have a mild sunburn, aloe-containing products can be very soothing. For more severe sunburn, and especially there is any chance it is infected or if it gets worse over time, see a heath care provider. Over-exposure to heat and sun can lead to heat-stroke; proper hydration and replenishment of body salts may be needed. For mild dehydration, consider drinks like gatorade.
