Aging is inevitable, and as we age, the brain shrinks, but not everyone experiences this shrinking equally. Some people have more brain cells than others; some people grow more than others; some people lose neurons while others don't. The brain is a muscle, and as you age, it grows smaller. More specifically, the cortex of the brain, which is the wrinkly outer layer of our grey matter, ages and becomes thinner.
The cortex is in charge of planning, reasoning, and thought. Additionally, it aids in the processing of new information and sensory input. The neurons in this layer of our brain become less effective in sending messages as we get older, making it harder for us to learn new things and create new memories.
Your capacity to reason coherently and solve problems may be significantly impacted by this reduction of your brain. Your brain changing is not always a bad thing. Our brains are built to change as we age, enabling us to maintain high levels of performance. We can learn new things and keep our mental faculties fresh as we age because of the brain's capacity for adaptation.
There is no evident explanation for this variation. It might be brought on by dietary or lifestyle variations, genetic predispositions, or even the way our brains are built at birth. However, given that CTE has been connected to a number of neurological conditions and cognitive impairment, the fact that some people do not experience considerable brain shrinkage is cause for concern. The brain shrinks by around 2% annually, a phenomenon known as brain shrinkage. One of the inevitable effects of aging is brain shrinkage, which can be prevented by adopting a healthy lifestyle.
According to Verywellhealth, this article will show you some habits that can prevent brain shrinkage brought on by old age.
1. Eat a balanced diet.
Whole grains, fruits, and vegetables, lean protein, and healthy fats are all components of a balanced diet. Get enough sleep. Studies have shown that lack of sleep has been linked to cognitive decline in both adults and children. This includes low-fat dairy products, some fish, and other dairy products.
2. No more than two drinks for ladies and three for men per day should be consumed, respectively. The typical American consumes three cups of coffee daily (one cup equals 8 ounces). Reduce your daily coffee consumption if you consume more than two cups. Caffeine overdose can disrupt sleep patterns and induce insomnia which can increase the risk of brain shrinkage.
3. Most days of the week, engage in at least 30 minutes of exercise. Regular exercise lowers the risk of Type 2 diabetes, heart disease, stroke, and obesity, all of which are conditions that worsen with age. Exercise also helps keep blood sugar levels steady (which also increases with age).
4. Avoid smoking and using other tobacco products, such as chewing tobacco and snuff (made by dipping tobacco into a jar), as these can hurt your mouth and lungs as you age and raise your chance of developing chronic lung conditions like emphysema.
