It is a well-documented fact in medical science that the ultraviolet rays and radiation have been considered as too carcinogenic for humans. This is a fact that has been endorsed by the World Health Organisation (WHO). These rays can causes a number of skin problems ranging from premature aging to skin cancer in case a person is exposed to the sun for prolonged periods of time. Read this article to know how sun exposure can put your aging process on the fast track.
- All about UV Radiation: UV or ultraviolet radiation is found in the sunlight which travels to the Earth in the form of electromagnetic waves. This radiation passes through the ozone layers with the sunlight and gets absorbed as waves of energy that one cannot physically see or feel. So, if we were to avoid wearing protective clothing, hats and sunscreen, then we would be exposed to these harmful rays. Aging is the number one form of damage that can be caused due to these UV rays which are also classified as UVA or UVB. These rays are the number one cause of premature aging, while smoking comes in a close second.
- Skin Cells: The UV rays basically have an adverse effect on the skin cells which can also spread to the DNA in our skin. This can have a negative effect on the protective functions of our skin which in turn, affects the way our dead skin cells get replenished. It can also affect the production of collagen which is the chemical that keeps our skin supple and young looking. It also has a bearing on how many other chemicals are produced in our body. Over production of certain chemicals can also spell doom and lead to premature aging and pigmentation. Melanin is one such chemical which can cause deep tanning and pigmentation if it is present in large quantities - a problem faced mainly due to sun exposure.
- Photoaging: When the sun damages our skin due to prolonged exposure, this can be termed as photoaging in medical terms. This also signifies the loss of the skin's ability to repair itself due to repeated episodes of being in the sun without ample protection, which can impair the collagen production as mentioned above. This will result in a loss of skin elasticity which in turn, will lead to sagging skin.
- Skin Changes: The changes in the skin will get tattooed onto the skin's memory which will retain its leathery texture that would be a result of too much sun exposure over time. This can also lead to premature aging.
Always step out with plenty of protection and do not stay in the Sun for too long in order to avoid this condition. If you wish to discuss about any specific skin problem, you can consult a specilized dermatologist and ask a free question.
