The dreaded sunburn is hard to avoid in some cases. The onset can be so quick that you rarely see it coming. However, this does not take away from the severity of it. Not only is sunburn painful, with tight, hot skin giving way to peeling and blistering, but it is also bad for your long-term health. Even a single serious burn early on can double your lifetime risk of developing melanoma later in life.
The best advice is to not get burned in the first place, and there are many resources to help you prevent sunburn. However, it is not always avoidable.
