Everyone has heard about the importance of wearing sunscreen when out in the sun. Pool owners should always have sunscreen nearby. Sunscreens are engineered to remain stable for three years, but it is always important to check the expiration date before use. If the expiration date has passed, you should discard it. It is important to note that sunscreen is intended to be used liberally, so one bottle or tube should not last an entire summer, let alone three. A liberal application is considered to be about one ounce for the entire body. Preventing sunburns in children is one of the best ways for them to avoid skin cancer later in life. Babies under six months of age should avoid direct sunlight as their skin is extremely sensitive to the sun. Fabrics with a tight weave will protect skin better than those with a loose weave.
A broad spectrum of sunscreen should be used. Protection against UVA and UVB rays with an SPF factor of at least 15 is recommended. Direct sunlight without sunscreen protection should be avoided between 10 a.m. and 4.p.m. Anybody over the age of six months of age should reapply a full coat of sunscreen every two hours.
