Understanding the Ultraviolet Rays:

When an object emits energy, that energy is called radiation. Ultraviolet radiation is a form of electromagnetic radiation, and the principal source of it is the Sun. Other sources of UV rays are torches, lamps, and tanning beds. People often get exposed to different radiations that range from high energy to low energy. Some of the examples are X-rays, Radio Waves, etc. UV rays fall in the middle of this scenario. It is not possible to see the UV rays as their wavelength are shorter, but it can be felt on the skin.

Types of Ultraviolet Rays:

There are three types of Ultraviolet Rays:

1) UVA - These rays are weak and mainly damage the skin cells that can lead to early aging, generating wrinkles on the face, and also cause other skin infections.

2) UVB - These rays are a little stronger and can cause melanoma or skin cancer.

3) UVC - These rays are the strongest among UV rays and most harmful for the human body. But fortunately, it does not reach directly on the Earth and reacts with the Ozone layer that protects the Earth. However, some of the man-made objects like torches, mercury lamps, and UV sanitizing bulbs that emit UVC are malicious to the human health.

Prevention:

To avoid skin disease caused by sunlight, people should avoid exposure to the Sun directly. However, sunlight is also imperative for good health as sunlight helps in the synthesis of vitamin D in the body. Therefore, few precautionary steps may help people avoid the UV rays directly. The steps include:

1. Covering the body parts that get direct exposure to the Sun.

2. Choosing to stay under the shade when the sun rays are strong and bright.

3. Using sunglasses and hats to protect your face and eyes.

4. Using a good quality of sunscreens whose sun protection formula (SPF) is high.

5. Drinking more water to keep the body hydrated.

Note: For better protection from the Sun, sunscreen with SPF-50 is adequate that is available in online pharmacies in India.

Conclusion:
Sunlight is important for life. It spreads positivity and vitamin D. That means it helps people both scientifically and emotionally. Therefore, it is not possible to avoid sunlight at an instant. However, it is also true that excessive exposure to sunlight will result in various skin infections, diseases, or may cause cancer. But if people can follow some measures to protect themselves from direct exposure, this may lead them to live a healthier life. People who tend to get exposed to artificial UV rays must stay alert and, if possible, should avoid the use of it entirely.

If you notice any irregularities and marks on the skin, please consult a doctor for help immediately. Immediate treatment may provide a great result.
