People who love to look radiant often wonder why they age, as it can reduce their natural glow and cause skin dullness. But the question is, why does a person age? Keep reading to find out.
Aging has always been a topic of interest for the scientist. A lot of research has been carried out to find out, why we age, what are the factors that contribute towards aging, And how the aging process can be slowed down?
Several theories explain aging differently focusing on different varieties. One of the widely accepted propositions is that life is destructive by nature and our environment and internal functions suffer from wear and tear over time. Moreover, we age because it is not in the interest of nature to perfectly repair our bodies.
The main objective of nature is to keep us reproductive as long as possible followed by health detonation. Aging is a complex phenomenon that involves the interaction of environment, genetics, chemistry, psychology, physiology, and behavior. The human body is designed and programmed with age, and there is a certain biological timeline that bodies follow.
Aging is generally caused by changes in genes, variations in hormone secretions, and a decline in the immune system of the body. Studies have revealed the fact that genes play a significant role in aging.
As outlined in a study reported by Immunity & Ageing, your genetic composition plays a pivotal role in shaping your inherent lifespan and the aging process. Certain individuals may possess genetic traits that predispose them to a slower aging rate, while others may carry genetic factors that render them more vulnerable to age-related conditions.
Certain types of genes can help a person to live longer. They are biologically superior in their performance and endurance and thus can help your body wither through rough patches successfully.
On the other hand, some cells deteriorate over time and gene mutation occurs. Even though all cells try to regenerate, some are poorly structured and thus are susceptible to internal and external factors.
What happens in these two scenarios is that even though these two people suffer cell degradation due to aging, one is likely to experience faster cell burn out than the other.
However other than genetic behaviors, our bodies continually undergo complex biochemical reactions. Some reactions cause damage and ultimately contribute to the aging process in our bodies.
The investigation of biochemical research shows that unstable oxygen molecules can damage cells in the body. Moreover, with aging protein molecules stick together causing the cells’ DNA structure to disintegrate.
As a result, their repair and multiplication become less effective. Still, heat shock proteins are depleted trying to fight off oxidative conditions. This situation interferes with how hormones work and hence causes hormonal change.
However, there is good news that many of the causes of aging may be modified by making changes in behaviors. Naturally, your body is designed to be active and persevering.
According to a report published in BMC Public Health, engaging in regular exercise provides a significant boost to the immune system, enhancing its ability to efficiently identify and eliminate damaged or abnormal cells. This immunomodulatory effect is instrumental in maintaining the overall health and well-being of the body. During physical activity, the immune system becomes more adept at surveilling and responding to cellular irregularities, thereby contributing to optimal cellular health.
Leading an active lifestyle can make the body’s cells more resilient. This helps to repair damages and withstand intense environmental shocks. Thus when you undergo trauma and such extreme cell mutilation, they can still regenerate and multiply.
Furthermore, telomere shortening plays a vital part in aging. Telomeres are cell chromosome areas with a high concentration of repetitive DNA sequences. Telomeres protect the ends of chromosomes from damage during cell division, by preventing their disentanglement and fraying.
During cell multiplication, however, telomeres have shown continual natural shortening with each division. Eventually, telomeres become too short to protect the chromosomes. At this juncture, the cells stop dividing or become senescent (meaning they no longer function properly).
This can contribute to tissue deterioration and aging. They eventually die. When this ravaging is too intense, more cells die than those that are repaired and multiplied.
Exercise is directly beneficial to the cell telomere’s length preservation. Aerobic exercises and consistency bring greater benefits to this cell’s chromosomal preservation. Hence, physical activities slow down the rate of aging.
Also, aging can be contributed to the accumulation of damage. Our cells and tissues can accumulate damage from a variety of sources, including exposure to UV radiation, cigarette smoke, and other environmental toxins. This damage can lead to DNA mutations, protein misfolding, and other cellular abnormalities, which can contribute to the aging process.
The decline in hormone levels is another factor that leads to aging. As we age, our bodies naturally produce fewer hormones, which can contribute to a range of age-related health issues. For example, declining levels of testosterone in men can lead to muscle loss, decreased bone density, and decreased libido. Similarly, declining levels of estrogen in women can lead to osteoporosis, cognitive decline, and other health issues.
As highlighted in a study featured on Medline Plus, hormones like growth hormone and testosterone assume a crucial role in upholding both muscle mass and bone density. Nevertheless, as individuals advance in age, the declining concentrations of these hormones can result in conditions such as muscle loss, commonly known as sarcopenia, and a reduction in bone density, a hallmark of osteoporosis. These age-related transformations can be a contributing factor to physical frailty and an increased vulnerability to fractures.
Changes in metabolism: As we age, our metabolism slows down, which can contribute to a range of age-related health issues. For example, our bodies may become less efficient at processing nutrients, leading to weight gain and other metabolic issues. Additionally, our bodies may become less effective at removing waste products from our cells, which can contribute to cellular damage and aging.
Apart from that, inflammation is another important factor in aging. Inflammation is a natural response of the immune system to injury or infection, but chronic inflammation can contribute to a range of age-related health issues. As we age, our immune system becomes less effective at controlling inflammation, which can lead to chronic inflammation and associated health issues. For example, chronic inflammation has been linked to arthritis, heart disease, and cognitive decline.
Aging is inevitable, but the aging process can be slowed down with a healthy lifestyle, nutritious food, which is rich in antioxidants, and practicing mental fitness.
