It is important to choose a sunscreen that is broad-spectrum in order to protect against both UVA and UVB rays. SPF and water resistance are also important factors to consider. Baby and kids sunscreens are often hypoallergenic and free of harmful chemicals. Fragrance-free sunscreens are also available for those with fragrance sensitivities. Finally, it is important to avoid aerosol sunscreen as it is less effective and can be dangerous for lungs and environment.

A higher SPF means that you can stay in the sun for a longer period of time without needing to reapply sunscreen. Sunscreens that are labeled “water resistant” will stay effective for longer periods of time when you are swimming or sweating. However, no sunscreen is 100% waterproof.

At 10 a.m. and 4 p.m., your shadow will be the shortest. This means that the sun’s rays will be hitting you directly, and you’ll be more likely to get sunburned. Seek shade during these hours, and use an umbrella at the shore or by the pool.
