Your brain is the most amazing organ in your body. It controls your thoughts, emotions, memory, learning, and behavior. It also regulates your vital functions, such as breathing, heartbeat, and digestion. That’s why you need to take good care of your brain and protect it from harm.
But many people have bad habits that can ruin their brain health and increase the risk of cognitive decline, dementia, and other brain diseases. Here are 11 bad habits that are killing your brain and how to avoid them.
1. Skipping breakfast
Breakfast is the most important meal of the day because it gives your brain and body the fuel they need to start your day. Skipping breakfast regularly can make you feel sleepy and unfocused due to low blood sugar. It can also starve your brain of the essential nutrients and signals it needs to function properly. This is especially important for kids and teens as their brains are still growing.
To avoid this bad habit, make sure to eat a healthy breakfast every morning that includes complex carbs, protein, fiber, and healthy fats. For example, you can have oatmeal with nuts and fruits, eggs with whole-wheat toast and avocado, or yogurt with granola and berries.
2. Eating a poor diet
Your diet affects every aspect of your health, including your brain. You need to eat a balanced diet that is rich in vitamins, minerals, antioxidants, and omega-3s that support brain function and protect it from oxidative stress and inflammation. On the other hand, eating too much sugar, refined carbs, saturated fats, trans fats, salt, and processed foods can harm your brain by impairing its blood flow, metabolism, and communication.
To avoid this bad habit,
cut down on junk food,
sweets,
soda,
fried foods,
red meat,
cheese,
and salty snacks.
Instead,
eat more fruits,
vegetables,
whole grains,
beans,
nuts,
seeds,
fish,
poultry,
eggs,
and low-fat dairy products.
3. Not getting enough sleep
Sleep is vital for your brain health because it helps your brain recharge itself,
consolidate memories,
remove toxins,
and repair damage.
Not getting enough sleep every night can damage your brain cells and lead to memory loss,
poor judgment,
attention problems,
mood disorders,
and increased risk of Alzheimer’s disease.
To avoid this bad habit,
aim for seven to nine hours of quality sleep every night.
To improve your sleep hygiene,
follow these tips:
- Stick to a regular sleep schedule
- Avoid caffeine,
alcohol,
nicotine,
and heavy meals before bed
- Turn off all electronic devices at least an hour before bed
- Keep your bedroom dark,
quiet,
cool,
and comfortable
- Do some relaxing activities before bed such as reading or meditation
4. Drinking too much alcohol
Drinking too much alcohol can damage your brain by messing with its neurotransmitters (chemical messengers) that regulate its functions. Alcohol can also cause dehydration,
brain shrinkage,
liver damage,
and vitamin deficiencies that affect brain health. Excessive alcohol consumption can impair your memory,
reasoning,
decision making,
and emotional stability.
To avoid this bad habit,
limit your alcohol intake to no more than one drink per day for women and two drinks per day for men.
One drink is equivalent to 12 ounces of beer,
5 ounces of wine,
or 1.5 ounces of liquor.
If you have a history of alcohol abuse or addiction,
you should avoid alcohol altogether.
5. Smoking cigarettes
Smoking cigarettes can harm your brain by reducing its oxygen supply,
increasing its exposure to toxins,
and damaging its blood vessels.
Smoking can also affect the levels of dopamine
and acetylcholine
in your brain,
which are involved in mood,
motivation,
learning,
and memory.
Smoking can increase your risk of stroke,
Alzheimer’s disease,
Parkinson’s disease,
and depression.
To avoid this bad habit, quit smoking as soon as possible.
There are many resources and treatments available to help you quit smoking,
such as nicotine patches,
gum,
lozenges,
sprays,
inhalers,
medications,
counseling,
and support groups.
You can also ask your doctor or pharmacist for advice on how to quit smoking.
6. Taking recreational drugs
Taking recreational drugs such as marijuana,
cocaine,
heroin,
or ecstasy can have addictive and harmful effects on your brain.
These drugs can alter your brain chemistry and disrupt the balance of serotonin and dopamine,
which are responsible for your mood,
pleasure,
and reward.
These drugs can also
damage your brain cells and impair your cognitive functions such as memory, attention, learning, and problem-solving. Taking recreational drugs can increase your risk of psychosis, schizophrenia, anxiety, depression, and suicidal thoughts.
To avoid this bad habit, stay away from recreational drugs and seek professional help if you have a substance use disorder. There are many treatment options available to help you overcome drug addiction, such as detoxification, medication-assisted therapy, behavioral therapy, and peer support groups. You can also talk to your doctor or a mental health professional for guidance and support.
7. Not exercising enough
Exercise is beneficial for your brain health because it can improve your blood circulation, oxygen delivery, and nutrient supply to your brain. Exercise can also stimulate the growth of new brain cells and connections, enhance cognitive functions, and protect your brain from aging and degeneration. Exercise can also boost your mood, energy, and self-esteem by releasing endorphins and reducing stress.
To avoid this bad habit, aim for at least 150 minutes of moderate-intensity aerobic exercise per week or 75 minutes of vigorous-intensity aerobic exercise per week. You can also do some strength training exercises twice a week to build your muscle mass and bone density. Some examples of aerobic exercises are brisk walking, jogging, cycling, swimming, or dancing. Some examples of strength training exercises are lifting weights, doing push-ups, squats, or lunges.
8. Not challenging your brain
Your brain needs constant stimulation and challenge to maintain its function and plasticity. Plasticity is the ability of your brain to adapt and change in response to new experiences and learning. If you don’t challenge your brain enough, it can become lazy and lose its capacity to process information and solve problems. This can lead to cognitive decline and dementia.
To avoid this bad habit, engage in mentally stimulating activities that challenge your brain and make you learn new things. For example, you can read books, do crossword puzzles, play chess, learn a new language, take a course, or play a musical instrument. You can also try to vary your routine and expose yourself to new environments and experiences that stimulate your senses and curiosity.
9. Not drinking enough water
Water is essential for your brain's health because it helps regulate its temperature, remove waste products, transport nutrients, and maintain its electrical activity. Dehydration can affect your brain function and performance by causing headaches, fatigue, confusion, irritability, and poor concentration. Dehydration can also increase the risk of stroke and brain damage.
To avoid this bad habit,
drink enough water every day to keep yourself hydrated and prevent dehydration.
The amount of water you need depends on various factors such as your age,
weight,
activity level,
climate,
and health conditions.
However,
a general guideline is to drink about eight glasses of water per day or more if you sweat a lot or exercise.
10. Not managing stress
Stress is a normal part of life,
but too much stress can be harmful to your brain health.
Stress can trigger the release of cortisol,
a hormone that can impair your memory,
learning,
and mood.
Stress can also cause inflammation in your brain and body,
which can damage your brain cells and increase the risk of depression,
anxiety,
and Alzheimer’s disease.
To avoid this bad habit,
learn to manage stress effectively and cope with it in healthy ways.
Some strategies to reduce stress are:
- Identify the sources of stress in your life and try to eliminate or minimize them
- Practice relaxation techniques such as deep breathing,
meditation,
yoga,
or tai chi
- Express your emotions in positive ways such as talking to someone you trust,
writing in a journal,
or doing something creative
- Seek social support from your family,
friends,
or community
- Engage in hobbies or activities that make you happy and relaxed such as gardening,
painting,
or listening to music
- Seek professional help if you feel overwhelmed or unable to cope with stress
11. Not wearing a helmet
Wearing a helmet is a simple but effective way to protect your brain from injury when you ride a bike,
motorcycle,
skateboard,
or scooter.
A helmet can reduce the impact of a fall or collision on your head and prevent skull fractures,
concussions,
bleeding,
swelling,
or bruising in your brain.
A traumatic brain injury (TBI) can cause permanent damage to your brain function and lead to cognitive impairment,
personality changes,
seizures,
coma,
or death.
To avoid this bad habit,
always wear a helmet that fits you well and meets the safety standards when you engage in any activity that involves speed or risk of falling.
You should also replace your helmet if it is damaged or worn out.
