Brain health

Simple ways to support your cognitive health

Brains might be small, but they do some pretty incredible work! They control your thoughts, feelings and movements, store memories, and shape your personality. It's easy to forget when it all happens behind the scenes, but our brain works hard every day, determining how well we think, learn and remember.

While some changes in memory and thinking can be a natural part of aging, there are simple every day habits that can help support cognitive health both now, and in future.

Brain health matters for everyone, but it can be especially important for people with a family history of dementia. As proud partners of Alzheimer's Society, we're passionate about helping people understand the lifestyle factors that can have impact. Simple choices such as staying active, eating a balanced diet, getting enough sleep and maintaining social connections can all contribute to your overall cognitive health.

In this guide, you'll find practical brain health tips, expert advice and simple ways to help support healthy brain function as you age.

"Looking after your brain is just as important as looking after your body. As partners of Alzheimer's Society, we feel it's important to address the importance of cognitive health. While there are often factors out of our control that can impact brain health, we can adopt small, positive lifestyle choices that can help support our overall wellbeing."

What is brain health?

Brain health refers to how well your brain functions across different areas of your life. These might include:

  • Memory and learning
  • Movement and coordination
  • Thinking and problem-solving
  • Communication
  • Emotional wellbeing
  • Social interaction

A healthy brain can help us stay engaged, connected and independent throughout our lives. It's important to remember that brain health matters at every age – not just later in life.

Why does brain health matter?

Our brains don't replace neurons (nerve cells) that are damaged or destroyed, so it's important to take care of them. Head injuries, drug use, and health conditions such as Alzheimer's and Parkinson's disease can all lead to the damage or loss of neurons.

Just like your heart, muscles and bones, your brain benefits from regular care and attention – so show it some love! To do this, you can try:

  • Engaging in regular physical activity (even just walking!)
  • Eating a balanced diet
  • Staying hydrated
  • Making sure you get enough sleep each night
  • Managing any long-term health conditions
  • Staying socially connected
  • Keeping your mind active (this might be through learning new skills, reading, doing puzzles or engaging in a hobby)

Research shows that factors such as physical health, the environment around us, social connection, and lifelong learning can have influence on the way our brains develop, adapt and respond to stressful situations.* While we can't control every factor that affects our cognitive health, being aware of our lifestyle choices is a simple way to help support brain function.

3 everyday brain health tips

MINDful eating

The foods we eat provide the essential nutrients our brain needs to function. Healthy eating patterns such as the MIND Diet can help support cognitive health.

Staying hydrated

Even mild cases of dehydration can affect how we feel, and could impact our concentration, energy levels and alertness. It's important to keep ourselves hydrated for optimum brain function.

Staying active

That goes for your body AND your mind! Regular physical activity (even just walking) can help support healthy blood flow throughout the body, including to the brain, while learning new skills, reading and taking part in engaging hobbies or puzzles are all ways to help keep your mind active.

Ear checks and cognitive health

Ear health and brain health go hand in hand. When hearing becomes more difficult, every day activities can become more challenging. Keeping up with conversations takes more concentration, social situations feel tiring, and communication becomes much harder. Even low levels of hearing loss have been associated with increased dementia risk and a decrease in memory and thinking skills**. To stay on top of your hearing health, you can book an Ear Health Check with us today.

When should you speak to a healthcare professional?

It's normal to notice some changes as we get older (such as occasionally forgetting names or misplacing items), however if you or someone close to you notices ongoing or worsening changes in memory, thinking, communication or day-to-day function, it's important to seek advice from a healthcare professional.

A pharmacist can offer advice on medicines, hydration and lifestyle factors that might affect your wellbeing.
