Wearing sunscreen is the easiest way to protect our skin from getting damaged by UV rays. UV rays cause damage to the skin and cause sunburn, skin cancer, premature ageing signs, hyperpigmentations and other health issues.
What are UV rays?
UV rays are ultraviolet radiation produced by the sun, the part of the broad-spectrum wavelengths from the sun. UV radiation is classified into three types, UVA, UVB and UVC. The principal cause of health issues is UVA and UVB because UVC has been filtered out by the atmosphere.
Under exposure to UV rays
We still need to expose ourselves to UV rays, and the sunlight is the primary source to make our body produce vitamin D. Vitamin D is crucial to keep our bones healthy for both adults and children. Lack of vitamin D may cause osteoporosis in adults and rickets in children. Again we don’t need to expose ourselves to the sunlight for too long because research shows that around 15-30 minutes three times per week is enough.
Excessive Exposure to UV rays
Excessive exposure to UV rays will cause many health issues, such as skin cancer, sunburn, cortical cataracts, sun spots, surfer’s eye, reactivation of herpes labialis, eye cancer.
Avoid the sunlight between 11 am-3 pm. The is when the UV levels are at their highest. If you have outdoor activities during that time, make sure you are wearing sun protection.
Sun protection to reduce health risk
- Wear sunscreen
- Wear sunglass
- Wear a hat
- Covered up with sun protected clothing
- Stay in the shade
The easiest way to protect ourselves from UV exposure is to wear sunscreen. We also need to get ourselves covered up when having outdoor activities especially, around 11 am till 3 pm.
Having excessive exposure to UV radiation may cause many health concerns, and too little exposure to UV radiation can also cause a deficiency in vitamin D.
