Exercising outside can help with motivation. However, being in the sun for long periods of time without the proper sunscreen can be damaging to the skin.
A sunscreen with an SPF of at least 30 should be applied liberally about 20 minutes before heading outside. This allows the sunscreen to soak into the skin, which will offer the best protection. A liberal amount is about 2 tablespoons applied on every part of skin that is not covered by clothing. Extra sunscreen should be applied to the nose and forearms, as they bare the brunt of the sun the most. It is necessary to reapply every two hours while outside.
When a person is exercising, they are sweating. The sweat may lessen the effects of the sunscreen, so it is important to reapply. The time of day that the person is exercising should be taken into consideration as well. No one should wear a sunscreen with an SPF of under 15.
If a person is taking certain medications, like ibuprofen, doxycycline and promethazine, these medications can make the skin even more sensitive to the light and ultra-violet rays of the sun. Clothing has built in SPF protection. A regular cotton shirt will offer about an SPF of 7. That will diminish once the shirt becomes drenched in sweat, so having a layer of actual sunscreen underneath would be beneficial.
Even if a bottle says it is good for all day coverage, it is still best if the sunscreen is reapplied every few hours. Also, tossing out any leftover bottles after summer is over is important, as these types of products lose their effectiveness over time.
