Cool Water Compress or Cool Bath
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Take a cool (not cold) shower or bath for 10-15 minutes. For targeted relief, soak a clean soft cloth in cool water, wring it out, and apply to burned areas for 10-20 minutes; repeat several times throughout the day. Do not use ice or ice-cold water, which can cause vasoconstriction and worsen tissue damage. After bathing, gently pat skin dry and immediately apply moisturiser while skin is still slightly damp.
How it works
Cool water dissipates excess heat trapped in sunburned skin, reducing the thermal component of inflammation. Lowering skin temperature slows the prostaglandin-mediated inflammatory response, decreasing pain, redness, and swelling. Cool water also temporarily closes dilated surface capillaries responsible for the characteristic flush of sunburn.
Where to buy
No purchase required. Thermal facial sprays (Avene Thermal Spring Water Spray, La Roche-Posay Thermal Spring Water) offer convenient on-the-go cooling: $10-$18.
Typical cost: Free (tap water); thermal sprays $10-$18
Safety notes
Avoid ice-cold water or ice packs directly on skin - the extreme cold can cause additional skin injury and frostbite on already-damaged tissue. Do not rub the skin with the cloth; pat gently only. If skin has open blisters, avoid submerging in bath water due to infection risk.
