Exposure to the sun

UV rays from the sun are the biggest cause of aging in our skin. These harmful rays damage cells and accelerate the skin aging process. UVA light damages skin at every level, including collagen fibers, elastin and tiny blood vessels. Over time, this damage leads to wrinkles, uneven pigmentation and sagging skin.
Gene structure
In fact, as recent research has revealed, the aging process can be directly linked to genetic makeup. Scientists have discovered that the aging process is triggered by the degradation of tightly packed DNA bundles known as heterochromatin. Understanding this process could lead to new ways to prevent and treat age-related diseases. The research was made possible by cutting-edge stem cell technology. The study also shows the potential for gene editing to counter the physiological decline that accompanies aging.
nutrition
Although there are many things outside of our control, one of the biggest causes of aging is our diet. The foods we eat can either slow down or speed up the aging process. Consuming high-fat, high-sugar, and processed foods can cause premature aging. Additionally, eating a diet low in fresh fruits and vegetables can accelerate the aging process.
stress
Chronic stress shortens DNA strands, which contributes to accelerated aging. It also affects the expression of the hormone telomerase, which corrects short telomeres. Studies have found that people with chronic stress have fewer telomeres than those without.
