Brain Health: Everyday Habits That Support Memory and Focus

Forgetting where you left your keys is normal. But many people worry about memory as they age, especially with dementia affecting more than 55 million people worldwide according to the WHO. The encouraging news from research is that a significant share of dementia risk is linked to factors we can influence. Here are the everyday habits that support a sharper, healthier brain.

Good News From the Research

The Lancet Commission on dementia prevention, an international expert panel, reported in 2024 that around 45 percent of dementia cases worldwide may be linked to 14 modifiable risk factors across the lifespan:

Less education in early life
Hearing loss
High LDL cholesterol
Depression
Traumatic brain injury
Physical inactivity
Diabetes
Smoking
High blood pressure
Obesity
Excessive alcohol
Social isolation
Air pollution
Untreated vision loss

Many of these overlap with heart health; what is good for the heart is generally good for the brain. See our heart health guide.

Habit 1: Move Your Body

Exercise increases blood flow to the brain and supports the growth of new connections. Studies have found aerobic exercise can increase the size of the hippocampus, a key memory region. A brisk daily walk is a great start; see the benefits of walking.

Habit 2: Protect Your Sleep

During deep sleep, the brain's glymphatic system is thought to clear waste products, including beta-amyloid associated with Alzheimer's disease. Sleep also consolidates memories. See our sleep hygiene habits.

Habit 3: Eat for Your Brain

The MIND diet, a hybrid of Mediterranean and DASH diets developed at Rush University, emphasises:

Leafy green vegetables (daily)
Other vegetables
Berries (at least twice a week)
Nuts
Olive oil
Whole grains
Fish (at least once a week)
Beans and poultry

and limits red meat, butter, cheese, pastries, sweets and fried food. Observational studies have linked closer adherence to slower cognitive decline, although a 2023 randomised trial found smaller-than-expected differences over three years. The overall pattern remains a sensible, healthy choice. See our anti-inflammatory eating guide.

Habit 4: Get Enough Omega-3s

DHA is a major structural fat in the brain. Eating oily fish regularly is associated with better cognitive health in observational studies. Read omega-3 vs omega-6; traditional sources include fermented cod liver oil.

Habit 5: Keep Learning

Challenging your brain builds "cognitive reserve", which may help it cope with age-related changes. Learn a language, play an instrument, take a class, read widely, play strategy games, or do crafts. Novelty and challenge matter more than any single "brain training" app.

Habit 6: Stay Social

Social isolation is one of the Lancet risk factors. Regular conversation, community activities, volunteering and shared meals keep the brain engaged and support mood.

Habit 7: Protect Hearing and Vision

Hearing loss in midlife is one of the largest modifiable risk factors identified. Get hearing tested, use hearing aids if recommended, and protect your ears from loud noise. Have your eyes checked regularly; see our eye health guide.

Habit 8: Manage Blood Pressure, Blood Sugar and Cholesterol

Vascular health and brain health are tightly linked. Know your numbers and work with your doctor; see our blood sugar guide.

Habit 9: Manage Stress and Mood

Chronic stress and untreated depression can affect memory and concentration. Use the tools in our stress relief guide and breathing exercises, and seek professional help for persistent low mood.

Habit 10: Protect Your Head

Wear a helmet when cycling and use seat belts. Prevent falls, as described in strength and balance for healthy aging.

Focus in a Distracted World

Work in focused blocks of 25 to 50 minutes with short breaks.
Turn off notifications; see our digital detox guide.
Take breaks outdoors; studies suggest nature walks can restore attention.
Stay hydrated; even mild dehydration can affect concentration.

The Gut-Brain Connection

Emerging research links the gut microbiome with brain function and mood. A fibre-rich, varied diet with fermented foods supports both; see our gut-brain axis guide.

When to See a Doctor

See a doctor if memory problems interfere with daily life, such as getting lost in familiar places, repeating questions often, difficulty managing finances or changes in personality. Some causes of memory problems, such as vitamin B12 deficiency, thyroid disorders, medication side effects and depression, are treatable.

Frequently Asked Questions

Do brain training apps work?

People get better at the specific games they practise, but transfer to everyday memory is limited. Learning real-world skills and staying socially active are better bets.

Is some forgetfulness normal with age?

Yes. Occasionally forgetting names or misplacing items is common. Memory problems that disrupt daily life deserve a medical check.

The Takeaway

Your brain thrives on the same habits as the rest of your body: movement, sleep, plant-rich food, social connection, learning and good heart health. It is never too early or too late to start.
