Your brain is the control center of your entire body—your thoughts, memory, movement, and emotions all depend on it. But what if something you’re doing every day is quietly undermining your brain’s well-being? According to renowned health educator Barbara O’Neill, certain overlooked lifestyle habits may negatively impact brain health over time. And the earlier you recognize them, the better your chances of protecting your mind for the years ahead.
Fortunately, you don’t need expensive treatments or trendy supplements to support cognitive wellness. Small, practical changes in your daily life can make a powerful difference. Let’s explore the most common yet harmful brain mistakes—and how to fix them naturally.
Why Brain Health Matters More Than EverAs we age, it’s normal to experience occasional forgetfulness or mental fatigue. But ongoing issues like memory loss, confusion, or trouble concentrating may signal that the brain isn’t getting the support it needs. According to the CDC, over 5.8 million Americans are living with Alzheimer’s disease, and many more experience cognitive decline that affects their daily lives.
Barbara O’Neill emphasizes that brain decline is not just a matter of age—it’s also deeply tied to what we eat, how we move, how we manage stress, and how well we sleep. That means you have more power than you may realize to influence your brain’s health, starting now.Common Habits That May Be Harming Your Brain1. Consuming Too Much Refined SugarExcess sugar can lead to blood sugar spikes and inflammation, which research suggests may affect brain structure and function. Studies published by Harvard Health and other institutions have linked high sugar intake to impaired memory and an increased risk of neurodegenerative diseases.
What you can do:Choose natural sweeteners like raw honey or dates in moderationCut back on sodas, pastries, and sugary snacksBalance every meal with protein, healthy fats, and fiber2. Skipping Sleep or Having Poor Sleep HabitsBarbara O’Neill often stresses the value of restful sleep as essential for detoxifying the brain. During deep sleep, your brain clears out waste products, including proteins linked to memory loss.
What you can do:Stick to a consistent sleep schedule—even on weekendsTurn off screens at least one hour before bedTry calming routines like herbal tea, reading, or stretching before sleep3. Living a Sedentary LifestyleMovement helps pump oxygen-rich blood to your brain and triggers the release of mood-boosting chemicals. Lack of exercise has been associated with reduced brain volume and higher risk of cognitive decline.
What you can do:Aim for at least 30 minutes of walking, dancing, or gentle stretching dailyTake breaks from sitting every hourTry new hobbies that involve movement like gardening or tai chi4. Chronic Stress and Negative ThinkingLong-term stress increases cortisol, a hormone that in excess may shrink parts of the brain responsible for memory and decision-making. Barbara O’Neill highlights the importance of maintaining peace of mind for long-term wellness.What you can do:Practice deep breathing or simple mindfulness for 5–10 minutes dailyWrite down your thoughts in a gratitude or reflection journalSpend time with loved ones, pets, or in nature to reset emotionallyNatural Ways to Support Brain Function Every DayNourishing your brain doesn’t require dramatic changes.
