Why UV Rays are Dangerous and Why You Should Avoid the Sun


Health

The sun is the earth's primary source of light during the day. As important as it is to humans and our atmosphere as a whole, it is also harmful. Here's how.

 

The sun emits harmful light known as ultraviolet rays which are not in any way useful to humans. Ultraviolet rays make up to 10% of the sun, and overexposure to the sun may bring about the adverse effects of ultraviolet rays.

 

Ultraviolet Rays And Vitamin D

It is widely known that the sun is a natural source of vitamin D., But it is best to get vitamin D from dieting and vitamin supplements. This would prevent you from being prone to the risks of ultraviolet rays from the sun.

 

Areas Of The Body Most Susceptible To UV Rays

 

There are some parts of the body that are most susceptible to UV rays, and they will be discussed in detail.

  • The Skin (Epidermis): The outer skin is prone to scalds, burns, or any kind of injury at all, as it is what covers and protects our entire body. It is the body's first direct contact with the sun. Since ultraviolet rays are invisible to most humans, it is quite difficult to see the harm it may be causing. Ultraviolet rays cause suntan, sunburn, skin cancer, premature wrinkles, and aging. It does this by killing the skin cells in the outer skin known as the epidermis, thereby making the skin to lose its elasticity. This result in wrinkles. Ultraviolet rays also make the skin dry out and makes it coarse.

  • The Eyes: The two pairs of human eyes are very important because, without them, we cannot see. Ultraviolet rays cause eye problems which may emanate from the formation of cataract or clouding of the lens of the eyes.

Why You Should Avoid The Sun

 

Yes, it is good to feel the sun on your skin, especially during summer, but it is not completely healthy to do so. The period when the sun's burning rays are most intense is between 10 am and 2 pm. This is when you should avoid the sun, wear sunshades or stay under a cover to avoid the sun.

 

You should avoid the sun because overexposure to the sun may bring about some negative effects on the body.

 

Here's a rundown of what overexposure to the sun may lead to:

  • Weakening of the immune system

  • Eye problems

  • Squinting/Poor vision

  • Tough and coarse skin

Weakening of the immune system: You may be wondering how the sun can weaken the immune system, which is an internal part of the body. Well, the sun rays can go as far as affecting the internal functions of the human body. Overexposure to the sun weakens the human immune system, making the body have a hard time fighting off infections. Also, vaccines taken may be less effective if a person is overly exposed to the sun.

Eye Problems: As the sun emits ultraviolet rays, it could lead to eye problems. If a person is always out in the sun, eye problems may start developing, which may, in the long run, be really harmful.

Squinting/Poor Vision: No one likes difficulty in seeing. Staying out in the sun causes squinting and an unclear vision.

Tough and Coarse Skin: The sun causes the skin to be tough and coarse. It also leads to darkening of the skin and sunburn.

To avoid the adverse effects of the sun and ultraviolet rays, you are advised to:

  • Avoid the sun altogether

  • If you must go out, wear sunshades and hats

  • Use good body creams that fight off the adverse effects of the sun.

While staying healthy, live, right!
