5 Common Habits That Are Very Bad For Brain Health

Many people who want to stay healthy commonly focus on their waistline, skin, kidney and heart. But there is a very important organ that most exercise and diet plans ignore -- the brain. 

It is one of the most complex organs and plays a key role in almost all functions of the body. However, it gets less attention when people say they want to be fit and healthy. 

It is important to know that the brain is sensitive and can also be affected by your lifestyle. What you do each day, what you eat and drink and how you socialize can either harm or boost your brain health. 

Studies suggested that simple lifestyle changes could help prevent cognitive decline. There are also brain-boosting diets, which provide short- and long-term benefits to the organ. 

For example, eating foods with good amounts of omega-3 fatty acids could help repair brain cells. Antioxidants might also cut cellular stress and inflammation, which delays brain aging.

However, since the brain is placed behind our eyes, people tend to ignore it and focus on other things that they can see and instantly feel. People prioritize the parts of the body where they feel more pain and easily recognize changes. 

There are habits that people continue to do as long as it appears not affecting their body weight, heart and skin. But these activities might have been slowly damaging the brain. Learn these activities below.

Bad Habits That Harm Brain Health

Covering Your Head When Sleeping

Sleeping with your head underneath the covers might potentially harm the brain since it cuts your oxygen intake. You could be breathing in the air you just exhaled. 

Lack of oxygen flowing to the brain could increase the risk of dementia and Alzheimer’s disease, according to Capital FM.

Poor Mental and Physical Exercise

Keeping an active mind and body could help promote better brain health. Lack of exercise negatively affects memory and might make you more likely to have dementia.

Some activities known to be effective to stimulate the brain include reading and socializing. 

Poor Sleep Quality

Having not enough sleep every night for a long period of time could harm the brain. It increases the risk of neurological disorders. 

During sleep, the body works to remove toxins and other byproducts from the brain. Chronic lack of sleep might delay such process and allow formation of harmful substances. 


Lack of water in the body not only affects your physical performance but also your brain. Dehydration could cause migraines, mood changes, irritability, anxiety and fatigue.

The brain contains water and being dehydrated reportedly could reduce the organ’s volume and affect its function.


Chronic stress triggers the production of a steroid hormone called cortisol. Having an excess cortisol in the body has been linked to hormonal imbalance, cancer, weight gain, heart disease and diabetes. 

Stress could also affect the adrenal glands. You might experience brain fog, memory loss and anxiety.
