Our brain, known as the command centre of the body, is a complex organ that requires constant care and attention. However, certain habits can significantly impair its function and overall health. Four main habits can influence poor brain health and affect cognitive function - too much sitting, lack of socialising, inadequate sleep and chronic stress, according to Harvard Medical School.
Sitting for too long: According to a study, excessive sitting can lead to changes in the medial temporal lobe (MTL), a brain region crucial for memory formation. Individuals who sat for prolonged periods had thinner MTL regions, which could potentially lead to cognitive decline and dementia. To counteract this, it's recommended to engage in physical activity every 15 to 30 minutes.
Lack of socialising: Loneliness and isolation can accelerate cognitive decline and increase the risk of Alzheimer’s disease. A study found that less socially active individuals experienced more significant loss of the brain’s grey matter, responsible for processing information.
Inadequate sleep: The Centers for Disease Control and Prevention (CDC) reports that one-third of adults don’t get the recommended seven to eight hours of sleep. Insufficient sleep can lead to a decline in cognitive skills such as memory, reasoning, and problem-solving.
Chronic stress: Persistent stress can damage brain cells and shrink the prefrontal cortex, the area responsible for memory and learning. Managing stress through mindfulness techniques, deep breathing exercises, and maintaining a flexible mindset can help protect your brain health.
Unhealthy diet: Overeating and consuming too much junk food can harm your brain. Overeating has been linked to memory loss and cognitive decline in older adults.
