Too much exposure to the sun and ultraviolet radiations makes us prone to sunburn and skin cancer later in life.

Types of Ultraviolet radiations.

Three types of ultraviolet radiation coming from the sun.

Ultraviolet A has a wavelength in the range of 315-400 nm and it is not absorbed from the ozone layer and completely reaches the earth.

Ultraviolet B lies in the range of 280-314 nm and is mostly absorbed by the earth and only the smaller amount has reached the surface of the earth.

Ultraviolet C lies in the range of 100-279 nm and it is completely absorbed by the ozone. None of it reaches the surface of the earth.

What is the UV index?

The UV index gives you the idea of how strong ultraviolent light is in your area and what protection do you need while going out in the sun. It has a scale from 1 to 11+. The greater the index, the greater will be the risk of sunburn and skin damage. You can find the index of your place by entering the zip code of your area at EPA’s website.

Diverse types of sunscreens

There are two diverse types of sunscreens.

Chemical Sunscreens contain active ingredients like oxybenzone, avobenzone and octinoxate.

When we apply the chemical sunscreen on the skin, it absorbs deep into the skin. When we go out and, in the sun, the chemical sunscreen absorbs the ultraviolent radiations and converts them into heat. Chemical sunscreen is best suited when we play sports and do swimming i.e. water-resistant formulation.

Physical sunscreens contain active ingredients like titanium oxide and zinc oxide. Physical sunscreen sits on the top of the skin and reflects ultraviolet radiation. It is less irritating to the skin and best suited for sensitive skin but, it cannot blend well and leave a white cast on the skin.

How to protect yourself from the damage of ultraviolet radiation?

Wear long clothes.

Wearing clothes that can cover your body is the best way to protect yourself from ultraviolet radiation. Many companies are offering lightweight and ultraviolet protective clothes. These clothes have the label UPF or ultraviolet protection factor. The higher the factor the more will be the protection from UV rays.

Protect yourself with sunscreen.

Applying sunscreen to the exposed areas of the skin can protect you from UV rays. Sunscreen is available in different forms like ointments, gels, sprays, wipes, lotions, and creams. Before choosing a sunscreen, always read the label. Choose the sunscreen with SPF values higher than 30 and having a broad spectrum that can block both UVA and UVB radiations.

Try to follow the directions written on the label. Sunscreen should be applied every 2 hours to maintain protection.

Limit your exposure to UV light by seeking shade or avoid going outside between the hours of 10 am and 4 pm.
