Your brain is your most valuable asset, responsible for everything from your thoughts and emotions to your physical movements and memories.
Unfortunately, some common habits can gradually chip away at its health and function. Here are 14 things you might be doing that could be harming your brain. That’s the last thing any of us want, right?
1. Chronic stress
Constant stress floods your brain with cortisol, a hormone that can impair memory and cognitive function over time. It can also shrink the hippocampus, a brain area crucial for learning and memory, per the National Institutes of Health. Find healthy ways to manage stress, such as exercise, meditation, or spending time in nature.
2. Sleep deprivation
Your brain needs adequate sleep to consolidate memories, repair itself, and function optimally. Chronic sleep deprivation can lead to impaired concentration, memory problems, and increased risk of dementia. Aim for 77–8 hours of quality sleep each night.
3. Poor diet
Your brain needs a steady supply of nutrients to function properly. A diet high in processed foods, sugar, and unhealthy fats can lead to inflammation and oxidative stress, which can damage brain cells and impair cognitive function. Focus on whole foods, fruits, vegetables, and healthy fats.
4. Lack of exercise
Regular physical activity increases blood flow to the brain, delivering oxygen and nutrients that are essential for brain health. Exercise also stimulates the growth of new brain cells and improves cognitive function. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
5. Social isolation
Humans are social creatures, and meaningful social connections are vital for brain health. Isolation and loneliness can increase the risk of cognitive decline and dementia. Make an effort to connect with friends, family, and your community.
6. Chronic dehydration
Your brain is about 75% water, and even mild dehydration can impair cognitive function, mood, and energy levels. Make sure you’re drinking enough water throughout the day, especially if you’re active or sweating.
7. Head injuries

8. Excessive alcohol consumption
Heavy drinking can damage brain cells and shrink the brain, leading to memory problems, impaired judgment, and other cognitive issues. If you choose to drink, do so in moderation.
9. Smoking
Smoking reduces blood flow to the brain and increases the risk of stroke, which can cause permanent brain damage. Quitting smoking is one of the best things you can do for your brain health.
10. Drug abuse
Illicit drugs can disrupt brain chemistry and cause long-term damage to brain structures and function. Get help if you’re struggling with drug addiction.
11. Multitasking
Contrary to popular belief, multitasking actually impairs your brain’s ability to focus and complete tasks efficiently. It can also increase stress and anxiety levels. Focus on one task at a time and give it your full attention.
12. Negative thinking
Chronic negativity and pessimism can create a toxic environment for your brain, increasing stress and impairing cognitive function. Practice positive thinking and gratitude to cultivate a healthier mindset.
13. Information overload
Constantly bombarding your brain with information from various sources can lead to mental fatigue and decreased focus. Take breaks from technology and give your brain time to rest and process information.
14. Not learning new things
Your brain thrives on challenge and novelty. Learning new skills, languages, or hobbies can stimulate brain growth and improve cognitive function. Keep your brain active and engaged by pursuing new experiences and challenges. It’ll make life a lot more fun, to boot!
