4. Uncorrected Hearing Loss
This is the most surprising factor on the list. If you have trouble hearing and don’t get a hearing aid, your brain has to work overtime just to process sound.
This extra effort drains energy from other functions like memory and thinking. Furthermore, hearing loss leads to social isolation (Habit #3), creating a double threat to your brain health. The Fix: Get your hearing checked. Hearing aids don’t just help you hear; they help you think.
5. Being Sedentary
Your brain consumes 20% of your body’s oxygen. If you don’t move, your heart doesn’t pump enough oxygen-rich blood to the brain.
A sedentary lifestyle is linked to the thinning of the medial temporal lobe, an area critical for memory. Physical activity, on the other hand, releases chemicals that promote the growth of new brain cells. The Fix: You don’t need a gym. A brisk 30-minute walk is enough to flood your brain with the oxygen it craves.
