Sun exposure for skin health is both good and bad. So, how can you determine how much sunlight is good?
Sunlight is good for our skin and a certain amount is necessary for health. But, on the other hand, sun exposure can also be bad and lead to a variety of problems including cancer. So, how do we get just the right amount of sunshine every day so that we only receive only its benefits and not the side effects?
Researchers have studied the benefits and side effects of sun rays for the past hundred years or so. They have concluded that UV rays emitted from sun’s rays have both positive and negative effects on human health. Over the years, because of the changes in climate and depleting ozone layer, our concern and focus has been only on the harmful effects on UV rays. It is true that skin diseases have increased a lot over the past few years because of this very reason. There are health risks of not getting enough sunlight too. So, we are here to also remind readers that moderate exposure can also benefit certain skin conditions and this has been stated by experts.
How Does It Impact Skin Conditions
Moderate exposure to sun rays is very good for skin conditions like eczema, psoriasis, acne and jaundice. For eczema, sun light can relieve the symptoms by triggering a release of a compound in our skin. This compound works to relieve inflammations in the skin which is the main cause of eczema. For auto-immune conditions like psoriasis, the UVB light rays are beneficial to treat the symptoms. They help in reducing the rapid rate of skin growth and shedding that create psoriasis patches.
For acne problems on the skin, experts state that sun rays can actually cause more harm than good. At first, it might help reduce acne but reducing sebum secretion in the skin. However, it can also trigger acne even more. Experts recommend that people should consult with a doctor regarding this.
