Hello, I am Your Brain: 7 Habits to Care for Me

Hello, I am your brain. If you’re wondering how to take care of your brain or looking for ways to protect your brain in your daily life, stay tuned because that’s what I want to discuss.

I am such an important organ that the scientific community established International Brain Day to promote my care, preserve my health, and prevent my deterioration. Although there are still mysteries about how I function, advances in imaging technology allow neuroscientists to observe in real-time how I activate when you perform certain actions.

Why is it so important to care for brain health?

I am a fundamental part of the Central Nervous System and operate thanks to the activity of approximately 86 billion neurons and various substances that act as neurotransmitters. My work enables you to carry out most daily activities.

One of my roles is to coordinate and regulate vital processes in the body, such as breathing, heart rate, blood pressure, swallowing, and digestion. I also enable voluntary movement. Moreover, I am responsible for what are known as cognitive skills, which allow you to perceive, understand, and interact with your environment:

attention, memory, perception, reasoning, language, motivation, planning ability, decision-making, social interaction, and self-awareness.

Additionally, I house the system that processes emotions.

Can the brain change and repair itself over a lifetime?

Yes, and this is one of the most exciting aspects I want to share. Despite my high status in your body, I am not a rigid or inflexible organ.

Scientists have discovered that throughout life, I have the ability to change certain structures: I create new neurons and generate alternate pathways for connections between them to adapt, recover, and respond to experiences and environmental stimuli. This ability is known as brain plasticity.

Let me be clear: healthy habits renew my cells and capabilities. Conversely, certain traumas, diseases, strokes, unhealthy habits, and aging can impact my health and promote my deterioration, paving the way for neurodegenerative diseases such as Alzheimer's and Parkinson's disease.

What can you do to care for my health? 7 habits

If you’re wondering what to do to take care of your brain without complicating your life, the good news is that it mostly revolves around everyday habits. Experts recommend incorporating the following practices:

1. Engage in physical exercise

Physical activity enhances blood flow to me and promotes the release of substances like endorphins, associated with emotional well-being, and dopamine, which gives you motivation and a sense of reward.

When exercised consistently, it contributes to the formation of new neurons and supports processes such as learning and memory. You can choose aerobic or anaerobic exercise, or simply walk for at least 30 minutes or dance at least three days a week.

2. Sleep between 7 and 8 hours daily

Sleep is crucial for my maintenance and recovery. Good sleep supports brain plasticity, strengthens connections between my neurons, and plays an essential role in learning. Conversely, lack of sleep affects areas related to decision-making and emotional regulation, which can lead to irritability, mood swings, and cognitive difficulties.

A sleep hygiene guide can help: go to bed and wake up at the same time, avoid screens and television before sleeping, steer clear of violent content, refrain from consuming coffee, sugar, or tobacco at night, and foster positive conversations and thoughts.

3. Maintain a healthy diet

Like rest, a balanced diet directly influences the production of neurotransmitters, communication between my neurons, and memory, learning, and emotional regulation.

A diet rich in antioxidants and healthy fatty acids, found in foods like fatty fish, tuna, and sardines, and low in refined sugars helps reduce inflammation and promotes healthy aging. Although I represent a small part of your body weight, I consume about 20% of your body's energy.

Thus, your diet should provide not only energy, protein, and fiber but also vitamins, minerals, and nutrients like omega-3, which helps protect me from inflammation, oxidative stress, and toxic substances.

It is advisable to consume plenty of leafy greens, nuts, berries, extra virgin olive oil, and fish. Equally important is limiting alcohol and other harmful substances for your physical and mental health.

An often-overlooked detail is the close communication between your gut and me, known as the gut-brain axis. Your gut houses thousands of nerve cells and microorganisms that form the gut microbiota, which contributes to the production of neurotransmitters that influence your mood. Various studies have found a link between imbalances in the microbiota and disorders like anxiety and depression.

Therefore, it is recommended to care for gut health with foods rich in probiotics, such as Greek yogurt, fresh cheese, kombucha, and other fermented products, along with prebiotics like garlic, onions, and blueberries.

4. Manage stress and cortisol levels

It’s important to understand cortisol, a hormone released when you need to be alert or respond to danger. Naturally, its levels rise during the day to help you tackle challenges and decrease at night.

The issue arises when cortisol remains elevated chronically: it becomes detrimental to me, promotes inflammatory processes, and affects my functioning.

Chronic stress and negative or catastrophic thinking are among the main triggers that elevate this hormone. Therefore, it’s crucial to learn to live in the present, rest, and develop a healthier relationship with your thoughts, as I cannot distinguish between what is real and what you imagine.

5. Practice relaxation and mindfulness techniques

Experts recommend incorporating habits that promote mental calmness and emotional well-being. Some options include practicing mindfulness, yoga, breathing exercises, daily meditation, or prayer.

6. Socialize

Being part of a social or family group, or simply being in contact with others, generates well-being: feeling that you belong, are appreciated, and supported keeps you motivated, active, and engaged in conversation.

Moreover, research indicates that those who interact with others improve their memory and other cognitive skills. People with an active social life are less likely to develop dementia than those who isolate themselves.

7. Continue learning

It greatly benefits me when you keep learning, acquiring skills, and exercising your abilities. Learning a language or an instrument, varying your routines and routes to work or the market, reading, writing, or learning dance steps are examples of how you can keep me in shape.

Taking care of your mental health also cares for me

Your mental health is just as valuable as physical health. In fact, they are interrelated because you are a biopsychosocial being. The World Health Organization itself recognizes brain health as a public health priority. Thus, when stress becomes difficult to manage, seeking help from a mental health professional can provide effective tools for regulating your emotions, controlling automatic thoughts, and developing skills that enhance your quality of life.

Care for me, and I will care for you

Spending time on my care improves your present and future quality of life. Physical activity, rest, a good diet, stress management, and strengthening your emotional health are simple actions that keep me healthy, active, and resilient over the years.

Ultimately, I am the organ that allows you to think, feel, learn, remember, and enjoy every experience in your life.

Frequently Asked Questions about How to Care for the Brain

How can I care for my brain daily?

Caring for your brain every day is simpler than it seems: move for at least 30 minutes, sleep between 7 and 8 hours, eat fruits, vegetables, fish, and healthy fats, manage stress, and maintain contact with loved ones. The key is consistency, not perfection.

What foods are good for the brain?

Foods that benefit the brain include fatty fish (rich in omega-3), leafy greens, nuts, berries, and extra virgin olive oil. Fermented foods like yogurt and kombucha also help because they support gut microbiota, which is connected to the brain.

Is it true that the brain can generate new neurons?

Yes. Thanks to brain plasticity, the brain can create new neurons and connections throughout life. Exercise, quality sleep, and continuous learning are some of the habits that most promote this process.

How many hours should one sleep for a healthy brain?

For adults, it is recommended to sleep between 7 and 8 hours a night. Good sleep strengthens connections between neurons and is essential for memory and learning, while lack of sleep affects decision-making and emotional regulation.

Does stress damage the brain?

Acute stress is normal and useful. The problem arises with chronic stress, which keeps cortisol levels elevated and can promote inflammation and affect brain function. Techniques such as mindfulness, breathing exercises, and, if necessary, professional support can help manage it.
