Experts refute some summer misconceptions.

To speed up the healing process, she recommends washing the wound with hot, soapy water. If the wound is red, painful or hot to the touch, consult your doctor.

There are several potential reasons for this, including lying down later while eating. fatter and sweeter, to increase screen time and sedentary behaviors, or to change sleep patterns. "
5. All drinks do not help to stay hydrated
False. "At the beach or by the pool, the best way to get hydrated is simply to drink water," explains Isabel Valdez. A soda or a cold beer can be refreshing in the hot summer temperatures, but do not hydrate. Alcohol and caffeine are diuretics, which cause the body to lose water.
