A chilly shower can be an effective treatment for a severe sunburn for several reasons:
1
The cooling influence of cold water helps to reduce the skin's temperature, providing immediate relief from the stinging sensation of a sunburn.
2
Cold water causes vasoconstriction, which narrows the blood vessels near the surface of the epidermis. This can help reduce sunburn-related edema and redness.
3
Cold water can temporarily numb the nerve endings in the burnt area, relieving pain and lowering discomfort.
4
A cold shower can help hydrate the skin by providing moisture and preventing more moisture loss.
5
A cold shower helps to chill the skin, preventing further injury and starting the healing process.
Cold showers should be taken for brief periods of time because continuous exposure to cold water might constrict blood vessels excessively and may not be good for everyone.
Other methods to treat a sunburn, such as applying aloe vera or a soothing lotion, staying hydrated, and preventing the skin from further sun exposure, must also be continued.
