Summer is a fun and adventurous season. You can go venture by the beach, go in a road trip with your friends, participate in festivals or simply just go out and take a walk around town to enjoy this new time of the year. In order to fully enjoy your summer experience, you must be mindful of the “dos and donts” of sun exposure.
Sun exposure is not bad in itself. It actually has beneficial effects. The UV rays from the sun stimulate the production of Vitamin D, which is vital for the nervous system and bone health as it regulates the body’s calcium metabolism.
It also boosts melanin pigment, known as the sun tan, in the skin which is responsible for protecting the skin from damage as it is an excellent photoprotectant. It absorbs the UVA and UVB that then prevents the skin from suffering in direct and indirect DNA damage. Only, too much of sun exposure will lead from just a few heat rashes to skin cancer.
What are responsible from this skin damage are the UV rays from the sun. They are actually just a small portion of the light spectrum. They have shorter wavelengths, which made them invisible to the naked eye. There are three types of UV rays: UVA, UVB, and UVC.
UVA stands for “ultraviolet aging” and is less intense than UVB and UVC, but is more prevalent. Ninety-five percent of the UVAs passes the ozone and reach the earth’s surface. It is responsible for skin wrinkling, premature aging, and can damage DNA cells. Tanning booths give large amount of UVA. The accumulation of which increases the risk of skin cancer.
UVB are the main cause of sunburns as it stands for “ultraviolet burning.” They are more energized rays, but only some reached the earth’s surface as the ozone absorbs them.
UVC are perhaps the most harmful, but fortunately it is being absorbed by the ozone.
Now that we know the different causes of skin damage, here’s the guide to protecting them.
SPFs, which stands for “sun protection factor,” protects us from UVBs. You should be aware how much of SPFs you need. SPF 60 can protect you ten hours from the sun, while SPF 40 protects you for six hours; however, if you want to go dipping in the water, it is best if you re-apply one hour and half to two hours. Since, SPFs are for UVBs only, be sure that you’re sunscreens also containing PA+++ as it will be your protection from UVA.
You’re already aware of the facts about UV rays, but it does not end there. Here are the last of the reminders before you go frolicking under the sun.
• It is advisable to use only SPF 40 for the face as the skin in this part is sensitive.
• Beach time is not the only “sunscreen-time.” Be sure to apply even when going outdoors as the UV rays can penetrate ordinary umbrellas, glasses, and also reflects into snow, sand and other reflective surfaces.
• As much as possible, avoid going outdoors between 10 am to 4 pm as the sun’s heat is the most intense during these times.
