Normal Aging is Not Disease – Adult Health and Wellness
Physical changes that accompany aging do not necessarily lead to disability. Aging does not necessarily mean that heart function, bone density, muscle strength, cognitive ability and memory, sexual desire and activity, physical and social functioning, or increasing levels of blood pressure, cholesterol, and anemia are associated with aging. However, there are some inevitable changes that occur with aging. Listed here are some of the expected changes that occur in various body systems as we age. The extent to which any particular body system changes depends on many factors, including our basic genetics, our lifestyle over the years, our emotional makeup, and how we’ve learned to deal with disappointments, losses, problems, setbacks, and general ups and downs. And the ups and downs of life.
o Heart and blood circulation
The heart becomes less efficient and has to work harder with age. The maximum pumping rate decreases and the oxygen in the blood decreases. The heart muscle gradually thickens and increases in size while fatty deposits and plaque build up in the artery walls causing the arteries to harden. As a result, many of us gradually lose energy and stamina over the years, and many develop atherosclerosis and other heart problems.
o Metabolism, body composition and body fat
A gradual decrease in metabolism with hormonal changes leads to a loss of muscle tone. Body fat increases until middle age, stabilizes for several years, and then gradually decreases in old age. However, as we age, the layers of fat redistribute to surround the organs below the skin. Women often store fat in the hips and thighs while men tend to have larger bellies. Drugs and alcohol are processed more slowly and reflexes are slowed when driving or participating in sports and other activities.
o Brain and nervous system
From our thirties, some neurons are gradually damaged and destroyed, blood flow decreases, brain weight decreases and brain cells gradually lose function, including memory changes, inability to recall recent events or remember names and details. However, the brain adapts to these changes by increasing the number of connections between the cells that carry messages (synapses) and between dendrites and axons (branch-like extensions). A study in the Journal of Neuropsychology suggests that higher education can prevent age-related cognitive decline and help older people draw on reserves from the frontal lobes of the brain. The life expectancy of a human being is about 115-125 years. In mammals, there appears to be a strong correlation between lifespan and brain weight.
From the mid-thirties, our bones gradually become less dense and stronger, losing minerals faster than they are replaced. Bone loss increases in many women after menopause, increasing the risk of osteoporosis. By age 65, one in three falls; One in 20 ends in a fracture.
o Lungs and breathing
Beginning in our twenties, lung tissue loses elasticity, rib muscles contract, and our maximum breathing capacity decreases. As we age, especially for inactive people, the lungs become less efficient and the body’s cells receive less oxygen.
o Kidneys and Bladder
Kidneys decrease in size and function with age, becoming less efficient at handling dehydration or removing wastes and certain medications from the blood. As bladder capacity decreases, urination may become more frequent and, if the tissue atrophies, urinary incontinence may occur.
Without exercise, muscle mass decreases by 22 percent for men aged 30 to 70 and 23 percent for men aged 30 to 70. Strong muscles, however, draw oxygen and nutrients from the blood more efficiently, work less for the heart, and support the heart. In order for the body to be sensitive to insulin and release sugar from the blood.
As we age, our bodies reduce collagen production and our oil glands produce less oil, causing our skin to gradually become less elastic, drier and more wrinkled. Age spots or liver spots (brown, yellow, white, or red) can develop due to melatonin depletion, waste product build-up, and carcinoma development.
o Hair and nails
Our hair and nails grow slowly as we age, and wounds also heal slowly. The hair on your scalp, pubic area and armpits gradually thins and the loss of hair pigment cells causes the hair to turn gray and eventually turn white. Nail discoloration can be a warning sign of a serious medical condition, but nail changes are rarely the first indication. For example, red nail beds can indicate heart disease, while pitting and flaking on the nail surface indicate inflammation such as arthritis. White nails may indicate liver disease or anemia, while yellowish, thick, and slow-growing nails may indicate lung disease.
