To people who have asked this question, the answer is contained in two words – Ultraviolet Radiation. UV rays are highly harmful to the health of a human being. It was recently declared a potent carcinogen. It is specifically detrimental to the skin which is most exposed to it.
UV radiation is capable of penetrating deep into the body’s tissues and causing irreversible damage. Australia, with its tropical climate, particularly experiences several sunny days. So wearing that shoulder wrap for the next soccer game in the sun may be an excellent idea.
Read on to find out more about the effects of sun exposure and how to combat it.
There are three kinds of rays
UVA, where the A means aging, has a wavelength of 320nm -400 nm. They speed up the aging process and actually cause wrinkles and cancer. The ozone layer does not do much to absorb this radiation. And so, it makes up over 95% of the total UV radiation entering the Earth’s atmosphere.
UVB radiation, where the B is for burning and most of it is trapped by the ozone layer. A small amount of it is good and helps the human body to make Vitamin D. Overexposure can cause extreme harm to the top layer of the skin. With ozone depletion, the amount of this radiation entering the atmosphere has drastically increased, and so has the rate of skin cancer.
UVC is the most dangerous among the three and fortunately is entirely blocked by the ozone. UV intensity is subject to change under the influence of the time of day and other such factors.
Issues that UV radiation causes:
- Skin allergies
What kind of clothes help block the UV radiation:
One must always give prominence to sun-protective measures like clothing, sunglasses, sunscreen, and so on. Because they reduce the harmful effects of exposure as much as possible.
Wear a shoulder wrap or arm sleeves to cover the body while playing outdoors. Thumbhole sleeves help cover the majority of the arm. Use scarfs, hats, and sunglasses when stepping out. Use sun protection that blocks out the different kinds of radiation for best results. It does not cost much to care about sun protection. One only has to be consistent at it.
Always keep these essentials in all the bags. So even if one forgets to take it while leaving the house, it will still be in the bag.
Radiation and Time of Day:
The amount of radiation varies throughout the day. When the sun is at the highest point in the sky from 11 pm- 1 pm, the radiation is strongest. Most of the radiation that enters the Heart does so during this period. Also, the radiation is more in higher altitudes as cloud cover lessens. There are lesser barriers to block them.
The necessity of Vitamin D:
One cannot be indoors all the time, and it is not advisable also. Everyone needs to get a little sun each day for a healthy body. Experts suggest that 15-20 minutes per day would be sufficient. And this exposure should be without sunblock to reap the benefits.
People with dark skin have more melanin, and they will need more than this amount to produce the required level of Vitamin D.
Sunburns and allergies are common, and one should take adequate protective measures. Be it clothing or skincare, always invest wisely to avoid damage to the skin and health. Take a hint from the celebrities who look gorgeous even in their 70s because they know how vital sun protection is daily.
