It is a good idea when exercising to replenish fluids every 20 minutes. Believe it or not, sport drinks are not necessary unless you are exerting yourself for 90 minutes at a time or greater. A good indication that you are drinking or replenishing fluids adequately is through monitoring your urine output. Urine output should be more frequent and the color should be light amber to clear. Put sunscreen on every day if you are going to be outside for more than 20 minutes.
Women can apply sunscreen under makeup.
Wearing a sunscreen every day may also help protect against developing wrinkles. Apply sunscreen to dry skin 15 to 30 minutes before going outdoors. Make sure to apply it to any part of your body that is not covered by clothes. Not all clothes provide protection against the UV rays. Use waterproof sunscreen when in the sun and near or in the water.
