Act quickly and get out of the sun if you feel tingling or see reddening of the skin.
Moisturize your skin after a cool bath or shower. Hydrocortisone cream can help alleviate discomfort.
Drink plenty of fluids and watch for signs of dehydration such as dry mouth, thirst, reduced urination, headache, dizziness and sleepiness.
Take ibuprofen for 48 hours to help lessen redness and swelling and possibly prevent long term damage to the skin.
If the sunburn is on more than 20% of your body or if you experience fever and chills, seek medical attention.
