Nestled within the complex architecture of the human body lies the brain. This intricate organ, weighing merely three pounds, serves as the command center for every thought, emotion, and memory we experience.
The brain's ability to adapt and rewire itself, known as neuroplasticity, underscores its remarkable resilience and capacity for learning throughout our lives.
Researchers from the University of Edinburgh found that a variety of factors, including smoking, high blood pressure, and diabetes—all conditions that affect your blood vessels or vascular risk factors—may also hurt your brain.
Over time, these factors may lead to brain deterioration and increase the risk of developing Alzheimer’s disease or other forms of dementia.
But are these the only factors that negatively impact our brain health?
In today’s video, we will delve deeper into 12 daily habits that may put our brain at risk without us even realizing it.

✍️ Summary:
Lack of Sleep
Lack of sleep doesn’t only make you tired. Most probably, you are unknowingly putting your brain at risk. During deep sleep stages, the glymphatic system, a waste clearance system in the brain, becomes more active, flushing out harmful proteins like beta-amyloid, which may accumulate and lead to Alzheimer’s disease if not adequately removed. Without sufficient sleep, this detoxification process is compromised, allowing toxins to build up and potentially damage brain cells.
Excessive Stress
When we encounter stress, the body releases cortisol, a hormone designed to prepare us for the fight-or-flight response. Cortisol has a direct impact on the hippocampus, a region of the brain crucial for learning and memory. High cortisol levels may inhibit the generation of new neurons in the hippocampus, leading to memory problems. Over time, this may even contribute to the shrinkage of the hippocampus, further impairing cognitive functions and memory.
Poor Diet
A diet high in sugar and unhealthy fats may lead to insulin resistance, a condition where the body's response to insulin becomes less effective. Insulin isn't just crucial for blood sugar regulation; it also plays a significant role in brain signaling. When insulin resistance occurs, it disrupts these brain signals, affecting cognitive functions and potentially increasing the risk of neurodegenerative diseases like Alzheimer's, often referred to as type 3 diabetes due to this connection.
Dehydration
Dehydration, even in mild forms, may have a profound effect on the brain, which comprises about 75% water. Water is essential for nutrient transport and biochemical reactions within the brain. When dehydrated, the brain struggles to maintain the energy levels required for these processes, leading to fatigue and impaired cognitive functions such as memory, attention, and decision-making.
Smoking
Nicotine, the addictive component of cigarettes, temporarily stimulates the brain, releasing neurotransmitters such as dopamine, which enhance mood and concentration. However, this is a double-edged sword. Over time, the brain adjusts to these surges in dopamine by reducing the number of dopamine receptors. This alteration not only diminishes the smoker's ability to experience pleasure, leading to increased smoking to regain the dopamine high but also impacts other dopamine-regulated functions such as mood regulation and cognitive processes.
