Your brain is the powerhouse of your body, with over 100 billion cells working in harmony to control everything from your heartbeat to your thoughts. However, some everyday habits, often overlooked, can seriously damage this incredible organ over time. Here are five brain-damaging habits that are more common than you might think—and how to stop them for a healthier mind.
1. Sleeping with Your Head Covered
You might love the cozy feeling of being entirely under the blankets, but this habit may deprive your brain of oxygen. Studies suggest that sleeping with your head beneath the covers increases the risk of dementia and Alzheimer’s disease by up to 23%. Breathing in recycled air reduces your intake of fresh oxygen, which can ultimately harm brain cells.
- Tip: To maintain optimal brain health, avoid covering your head with blankets or sheets while sleeping. Instead, keep your head exposed to ensure a steady oxygen flow.
2. Chronic Sleep Deprivation
Many of us push through the week on minimal sleep, but long-term sleep deprivation can be incredibly harmful to the brain. A chronic lack of rest not only affects memory and concentration but may also raise the risk of neurodegenerative diseases like Alzheimer’s. During deep sleep, your brain performs essential housekeeping, clearing out toxins that accumulate throughout the day. Without enough sleep, these toxins build up, potentially causing lasting harm.
- Solution: Aim for 7–8 hours of uninterrupted sleep each night. If falling asleep is a challenge, establish a calming bedtime routine. Relaxation techniques, such as reading or gentle stretching, can help prepare the mind for rest.
3. Ignoring Hydration Needs
It’s easy to overlook hydration, but water is vital for brain function. Since three-quarters of the brain is water, even mild dehydration can impact mood, focus, and cognitive performance. Dehydration has been shown to shrink brain volume temporarily, leading to headaches and fatigue.
- Quick Fix: Drinking water can reverse dehydration symptoms within about 20 minutes. For faster absorption, choose cold water, as it enters the bloodstream 20% faster than room-temperature water.
Quote from a 2013 Study: “Mild dehydration can affect mental performance, resulting in decreased cognitive function and poor mood.”
4. Living in Constant Stress
While stress is a part of life, chronic stress causes real harm to the brain. Under stress, the body produces cortisol, a hormone that, when elevated over time, can disrupt memory and reduce brain function. Prolonged exposure to cortisol is linked to increased risks of anxiety, brain fog, and even DNA changes. Excessive stress also takes a toll on the adrenal glands, leaving you feeling exhausted.
- Solution: Managing stress effectively can help keep cortisol levels balanced. Consider integrating daily stress-relief techniques such as mindfulness, breathing exercises, or even regular physical activity. Engaging in hobbies and connecting with supportive friends and family are excellent ways to maintain emotional balance.
5. Lack of Mental Stimulation
There’s truth in the saying “use it or lose it.” A brain deprived of stimulation can weaken over time. Engaging in mentally challenging activities is crucial for preserving cognitive health. Studies reveal that people who regularly participate in intellectually stimulating activities are less likely to develop conditions like dementia and Alzheimer’s.
- Ways to Stimulate Your Brain:

- Stay socially active: Engaging with friends or joining groups can boost brain function.
- Learn something new: Take an online course, attend a workshop, or pick up a new hobby.
Regular mental exercise not only boosts memory but also encourages the brain to adapt and grow—no matter your age.
