Causes of Aging

Aging in humans is caused by different factors. The rate at which people age is therefore different. However, the causes of aging can be more or less the same.

There are two main causes of aging, intrinsic and extrinsic causes. Intrinsic causes of aging involve our internal mechanisms while extrinsic causes are mostly environmental based.

Intrinsic causes of aging are controlled by our genetic structures. These are the genes we inherit from our parents. There are some rare cases where genes which cause rapid aging are inherited. This is a condition called Werner’s syndrome.  However, you need to remember that even if genes are internal, external conditions can alter the genes causing mutations.

Extrinsic causes of aging include those in the natural environment or also those which we introduce into our bodies. They include the following.

One of the main forces on the earth which controls movements is gravity. It affects aging where it affects posture and the skin. Aging comes with the sagging of both posture and the skin.

The sun is another extrinsic cause of aging that usually affects the skin. The sun is beneficial but also damaging when it comes to aging. In terms of benefits, it is the main source of vitamin D when it is synthesized by the skin. However, it’s also has its negative effects when dangerous ultraviolet rays contact our skin. These cause discoloration and risk of cancer. The sun also produces heat which if in excess dehydrates the skin.

Food is another extrinsic cause of aging. What we eat determines whether our body will age fast or not. If the food leaves a lot of toxins in the body, then you are at risk of accelerated aging. It is therefore important to eat healthy.

The state of the environment is another extrinsic cause of aging. People in clean environments are less exposed t toxins and therefore age less fast than those found in polluted environments.
