Now that scientists have explored clear causes why aging occurs, they are beginning to discover what can be done to age more slowly and stay younger for longer. Let’s see the main causes of aging first.
Shortening of Telomeres
At the ends of the chromosomes in our cells, there are structures called telomeres whose role is to provide structural stability and protect chromosomes from degradation. However, each time a cell divides, loses a piece of telomere, so that they become shorter with the passage of time. When the telomere is too short, the cell dies, contributing to the aging process.
There is an enzyme called telomerase which is responsible for repairing shortened telomeres. However, the amount of telomerase available may be decreased by effects of certain factors such as stress, accelerating the aging process.
It is the damage to DNA, proteins and lipids caused by free radicals and peroxides, highly reactive oxygen-containing substances. Oxidative stress occurs when we breathe and because of inflammation, infections, alcohol and smoking.
It occurs when glucose (sugar) is attached with some of our proteins, lipids or DNA, causing permanent alterations that prevent them from functioning normally. These reactions have an influence not only in aging but the emergence of diseases such as diabetes, cataracts, impaired skin, tendons and bones, atherosclerosis or Alzheimer’s disease.
What can we do?
In general, the main factors that cause us to age are age and genes, which are not under our control. However, there are other factors that have a major impact and we can control them.
Stress causes increased levels of stress hormones such as cortisol, which decreases the supply of telomerase. When a person is exposed to chronic stress, their telomeres are similar to those of a much older person. Therefore, learning techniques to manage stress properly can help you stay young longer.
People with psychological disorders such as depression or certain diseases such as diabetes, cancer or heart disease often have shorter telomeres.
It has a protective effect and has shown to have many beneficial effects for both emotional and physical health.
