Not long: Sperm don't live in the air, on clothes, or on other items. Their natural habitat is warm, fresh semen... not on household objects. Therefore, fresh semen on hands, penises, condoms, etc., that is quickly put into a vagina can still lead to pregnancy.
3. Decrease the Inflammation. At the first sign of sunburn, taking a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen, naproxen or aspirin, can help with discomfort and inflammation, says Dr. Brackeen, who practices at the Skin Cancer Institute in Lubbock, Texas.
Cool Bath: A cool bath is also an effective remedy. Cool water provides good treatment for a sunburn patient. It helps relieve pain, itching, and inflammation. Do not use perfumes, oils, or bath salts during the bath, as they can increase skin sensitivity.
