Sunlight has an important role in maintaining our bodily functions like our circadian rhythm and Vitamin D production. The skin, after being exposed to the sun, produces Vitamin D from cholesterol. 

 

However, too much sun exposure is harmful because ultraviolet (UV) radiation can cause damage to our skin both long-term and short-term including sunburn, wrinkling, photoaging, age spots, and even skin cancer. 

 

Some people still go to the beach and bask in the sun without anything to protect their skin since tanning is like the trophy for your ideal beach day. However, according to Harvard Health Publishing, this is not recommended because prolonged UV light exposure puts you at a greater risk of sun-related damage even at times when it isn't summer. Even in cold places or seasons, you have the possibility of getting sunburn, like when snow reflects the sunlight. 

 

Using sunscreen is effective in protecting yourself from the sun because they contain filters that absorb, reflect, and scatter UV radiation that might reach your skin. 

 

So what's the most effective way of using it?

 

Havard Health Publishing recommends that you practice the "teaspoon and shot glass rule". It states that you use 1 teaspoon of sunscreen for your face and neck, and one shot glass, approximately 1 ounce, to apply to exposed areas of your body.

 

Furthermore, you should apply your sunscreen 15-30 minutes before sun exposure, and wait for it to dry for around 10-20 minutes before putting on your clothes. It is recommended that you reapply every 2 hours and use additional protection like hats, sunglasses, and additional clothing. 

 

So on your beach days or normal days when sun exposure is unavoidable, don't forget to apply your sunscreens.
