When Sun Light Becomes Dangerous…
Too much sun exposure is always harmful. The skin undergoes negative changes on account of the ultraviolet rays present in the sunlight. The biochemistry of DNA might get altered; cell membranes can distort; and there can be an adverse effect on proteins and amino acids present in the body. Dilation of blood vessels indicates a reaction of your body to the detrimental sunrays.
Besides this, too much exposure to sun causes skin cancer, including the deadly melanoma. About 90 percent of all skin cancer cases are a result of excessive sun exposure. If your skin is highly sensitive, take vitamin D, not from sunlight, but from other sources like cod liver oil and supplements.
Ultraviolet Rays Are More Deadly Than You Think…
Ultraviolet (UV) is the invisible part of sunlight. It can pierce through your skin and alter its structure. There are 3 kinds of ultraviolet rays:
- Ultraviolet A – it is found in abundance on earth’s surface and can penetrate deep into the top layer of skin. It can damage connective tissues and increase the risk of skin cancer.
- Ultraviolet B – this is also a damaging radiation, but thanks to the ozone layer, a significant part of this radiation is absorbed by the layer. Hence, it’s less abundant on earth’s surface.
- Ultraviolet C – this is the most dangerous radiation, but relax, the stratospheric ozone layer of our atmosphere absorbs it completely!
