What is one of the signs of overexposure to UV radiation?

Redness and peeling are strong indicators of overexposure to UV radiation. When skin is overexposed to UV rays, it undergoes a burn reaction, often referred to as sunburn, which manifests as redness due to increased blood flow to the area as the body attempts to repair the damage. This condition can also lead to peeling as the outer layer of skin renews itself in response to the damage. The presence of these symptoms typically suggests that the skin has absorbed more UV radiation than it can handle, highlighting the importance of proper sun protection and moderation in tanning practices.
