1. Take a Bath
Adding a few heaping tablespoons of baking soda to cool bath water makes a sunburn-soothing remedy. Just keep your soaking time down to 15 to 20 minutes. If you soak any longer, you risk drying out your already lizard-like skin. When you've emerged from the bath, resist the urge to towel off. Instead air-dry, and don't wipe the baking soda off.Oatmeal added to cool bathwater offers another wonderful relief for sunburned skin. Fill up the bathtub with cool water--not cold water because that can send the body into shock. Don't use bath salts, oils, or bubble bath. Instead, scoop 1/2 to 1 cup oatmeal -- an ideal skin soother -- and mix it in. Another option is to buy Aveeno, an oatmeal powder found in the pharmacy. Follow the packet's directions. As with the baking soda, air-dry your body and don't wipe the oatmeal off your skin.
