Common Habits That Can Damage Your Brain



brain health

There are certain lifestyle habits that affect the brain. These habits can threaten the health of our brains significantly, even when the connection isn’t obvious. Here are seven dangerous habits that damage your brain.

Skipping breakfast

Breakfast is considered the most important meal of the day and skipping this meal can result in low blood sugar levels, which is very damaging to the brain.

Excessive stress

While situational stress is good for the body as it prepares it to fight or flee in the face of danger, chronic stress builds up the hormone cortisol in the brain and causes lasting damage. Chronic stress also kills brain cells and causes the brain to shrink.

Sleep Deprivation

 Insufficient sleep deprives you of neurons and the ability to function properly. Also, lack of sleep dulls the senses and reflexes. Chronic sleep deprivation can make these effects permanent.


 The body is made up of 70% water so it is critical to every bodily function, including brain function. The effect of dehydration on your brain happens really quickly too, with researchers determining that even just two hours of heavy exercise without water can cause cognitive decline.


According to several studies, there is a connection between obesity and dementia and while the reasons are unclear, it is suspected that obesity occurs when the food we eat lacks nutrition, leading to the desire to overeat in order to meet the body’s need for vitamins and minerals. So even if you eat a lot, you could still be starving your brain.

Too Much Sugar

 Although the body and brain need sugar to function properly, too much of it on a regular basis can cause your cells, including brain cells, to go into a state of chronic inflammation.


Smoking is one of the habits that have negative effects on the body and clearly damages cell membranes and neural viability in the areas of the brain that manage balance, coordination, and both fine and gross motor skill.
