Reapply it every two hours or sooner if you are sweating too much. Try to include foods rich in calcium, selenium, zinc, and beta carotene in your diet to protect your skin from UV damage (4).

How Is Sun Rash Different From Sunburn And Heat Rash?
While sun exposure is the cause of both sunburn and sun rash, they are not the same. Sunburn is a radiation burn caused by overexposure to UV light, which results in reddish skin. You may also develop swelling, blisters, fever, chill, or weakness in case of a severe sunburn. Usually, a sunburn heals in a few days. However, the likelihood of developing skin cancer increases with an increase in sunburn incidents (5). Unlike sunburn and sun rash, heat rash does not occur due to the sun alone. Instead, it occurs due to the sweat glands getting blocked, which causes skin inflammation and rashes. As a result, you may get small blisters or deep lumps that are itchy. These rashes appear on the armpits, elbow creases, or the groin area. In most cases, the rash heals after the skin cools down (6). However, you may need to consult a doctor if the area becomes infected or is too itchy. If your sun rash does not reduce or recurs despite taking all the precautions, it is time to see a doctor.
When Should You See A Doctor?
Consult a doctor if the itching on your sun rash does not reduce. A doctor can also help you rule out other infections, like contact dermatitis. Expert diagnosis will let you know what kind of sun-induced rash it is. If you do not have a history of sun rash and suddenly get one, seek immediate medical attention. Also, observe your rash and treat it immediately if it is painful or spreading. You should also be careful if you experience nausea or fever. Does Benadryl help with sun rash? Yes. Benadryl is an antihistamine which may help reduce the redness, itching, and other symptoms of sun rash. Consult your doctor for further information. What lotion is good for sun rash? You can use gentle moisturizers or creams containing hydrocortisone for relief.
