Effects of solar radiation on human health
Studies have shown that ultraviolent radiation can be both harmful and beneficial for human health. There are three types of ultraviolent radiation. UVA which account for up to 95% of the UV radiation reaching the Earth’s surface, penetrates the skin more deeply than UVB and is mainly responsible for the photo-aging. UVB, that only a small amount reaches the earth. It is thought to be more dangerous than UVA because it is responsible for the most types of skin cancer. UVC is the most dangerous type and it is all absorbed by the stratospheric ozone. Therefore the ozone depletion is one of the most important environmental problems.
Sunscreens are a very common solution to protect our skin from UV radiation but it is not the safest way. Studies have shown that some ingredients act as endocrine disruptors, enter the endocrine system and can cause endocrine and fertility problems.
Solar radiation has many negative effects to the human health such as sun burning, skin cancer, ophthalmic diseases, allergic reactions and phototoxic reactions when combined with some cosmetics and medicines. It is also known to be the main reason for photo-aging.
Our exposure to the solar radiation has not only negative effects, but also some positive. Sun exposure improves our mood and makes us happier. Solar radiation is also the most common source of vitamin D. UVA and UVB radiation are used in radiotherapy for various diseases such eczema and psoriasis.
