Aging is a progressive physiological changes in an organism that lead to senescence, or a decline of biological functions and of the organism’s ability to adapt to metabolic stress. Aging takes place in a cell, an organ, or the total organism with the passage of time.
From the moment we are born, we start aging. Constant exposure to the environments, things we eat, stresses from both inside and outside our body causes us to age overtime. Some of the processes of aging we cannot change while some we can influence and change. The natural process plays a key role, with time lines appear on our face, our skins becomes thinner and drier, hair begin to turn grey etc, all this things are controlled largely by the gene, medically it is referred to as intrinsic aging. While another type of aging that is influenced by our environment and our choices of lifestyle is called extrinsic aging like premature skin changes.
How to prevent aging
Because aging is the biggest risk factor for most of the disease that affect us as adults, the older we get the higher our risk of chronic disease becomes.
Eating a well balanced diet:
It’s no surprise that eating a well balanced diet has a long-term health benefits.When we pack our diet with vibrant foods loaded with antioxidants, healthy fats, water, and essential nutrients, our body will show its appreciation through its largest organ: our skin. Diets full of fruits, vegetables,nuts, legumes and even meats have proven to
- reduce blood pressure
- Improving glucose controlling diabetes
- Weight loss
- Improving arthritis
- Lower cancer risks
- Lower cardiovascular disease risks
Caloric restriction (CR) can extend the average and maximum life span and delay the onset of age-associated changes in many organisms.
Regular physical exercise:
Regular physical exercise can help maintain healthy weight, improve good sleeping habitat and boost overall health which makes people age more slowly. Calculations based on the Harvard Alumni Study suggest that men who exercise regularly can gain about two hours of life expectancy for each hour of exercise.
Prevent your body from ultraviolet rays:
The rays from the sun penetrates the skin and damage the elastic fibres that keep it firm thereby forming wrinkles. It is also responsible for the aging spots called “liver spot” found in areas frequently exposed like the hands, face etc. Whether spending a day at the beach or running errands, sun protection is essential. You can protect your skin by seeking shade, covering up with sun-protective clothing — such as a lightweight and long-sleeved shirt, pants, a wide-brimmed hat, and sunglasses with UV protection.
Studies have shown that those with strenuous jobs or work are linked with shorter telomeres, Telomeres, the specific DNA–protein structures found at both ends of each chromosome, protect genome from nucleolytic degradation , unnecessary recombination, repair, and interchromosomal fusion. Telomeres therefore play a vital role in preserving the information in our genome. When telomeres becomes too short, it can die or get damaged, this speeds up the aging processes.
Cigarette contains toxins that damages the elastic and collagen fibres that help keep the skin firm thereby by allowing wrinkles to form. It also makes the skin dull and a sallow complexion.
Moderate your alcohol intake:
Too much alcohol is not good for the skin, it causes noticeable changes in a person’s appearance which can result in premature aging. Alcohol dehydrates the skin thereby making it to be thinner and drier. So alcohol should be taken with every moderation to avoid any of its consequences to human health.
