When we talk about health, we often think about the heart, lungs, muscles or other parts of the body. But one important part is often overlooked — the brain.
Brain health plays a major role in how we think, remember, concentrate, make decisions and manage our emotions. The way the brain works can also affect how we feel and function in our everyday lives.
And while brain health is often associated with ageing or memory loss, everyday habits such as sleep, stress, alcohol use, mental activity and social connections can also play an important role.
A discussion between Dr Frankie Jackson-Spence and Dr Faye Begeti on a health podcast highlighted how some of these simple lifestyle factors can influence brain health over time.
Why Brain Health Matters
The brain controls many of the things we do every day. From remembering information and focusing on work to making decisions and managing emotions, healthy brain function is important for everyday life.
This is why taking care of the brain should not only become a concern later in life. The habits we build over the years may also contribute to how well our brains function as we age.
One of the biggest messages from the discussion was that brain health does not necessarily require complicated solutions. Some of the most basic habits — including getting enough sleep, managing stress and staying mentally active — can make a difference.
Stress Can Affect More Than Your Mood
Stress is everyday factor that can influence brain health. Short-term stress is not always harmful. It can sometimes improve alertness and help a person perform better in a particular situation. The problem can arise when stress becomes constant or prolonged.
Chronic stress can affect brain functions linked to memory, emotional regulation and concentration. It can also affect several important areas of the brain.
The amygdala is involved in emotional responses, while the hippocampus plays an important role in memory. The prefrontal cortex is connected with concentration, decision-making and emotional regulation.
Long periods of stress can sometimes lead to memory problems that may even resemble symptoms of dementia. According to the conversation, some people experiencing such problems may eventually be referred to memory clinics.
This is why being constantly overstressed, overworked and under-rested can become a serious challenge for overall brain health.
Sleep and the Brain Are Closely Connected
Sleep is one of the simplest parts of our daily routine, but it can have a major connection with brain health.
There is no single number of hours that works perfectly for everyone. Eight hours is often considered an average, but individual sleep requirements can be different. Some people may function well with 6–7 hours, while others may need 10–11 hours.
Rather than focusing only on a fixed number, maintaining a regular sleep and wake-up schedule can also be important.
A consistent wake-up time can help keep the body’s internal clock in rhythm. Getting natural light in the morning can also help regulate the body’s circadian rhythm.
Even spending around 10–15 minutes outside in the morning, when possible, can be helpful. More time outdoors has also been associated with lower levels of tiredness, insomnia and depressive symptoms.
Sleep may also have another important role. It helps the brain clear certain proteins that are associated with neurodegenerative diseases.
So, the next time sleep feels like something that can be sacrificed for work or other responsibilities, it may be worth remembering that rest is also part of taking care of the brain.
Alcohol Also Affects the Brain
Alcohol is often discussed in terms of its effects on the liver, but it also directly affects the brain. It can influence areas such as the cerebellum, which is involved in coordination and balance, and the prefrontal cortex, which plays a role in judgement and emotional regulation.
The conversation highlighted that making alcohol a daily habit may have long-term effects on brain health.
Even having one or two drinks every day over many years can have an impact. The advice highlighted in the discussion was to keep alcohol occasional rather than making it part of a daily routine.
Keep Your Brain Active
Looking after the brain is not only about avoiding things that may harm it. Giving the brain new challenges can also be useful.
Regular mental stimulation can help build what is known as cognitive reserve. This refers to the brain’s ability to cope with changes associated with ageing.
There are many simple ways to keep the brain challenged. Learning a new language, taking up a hobby, painting, learning a new skill or trying an unfamiliar activity can all provide mental stimulation. Social connections can also be part of this process.
The basic idea is simple: the more cognitive reserve a person builds over time, the more they may have to draw on later in life.
Can These Habits Prevent Dementia?
There is no guaranteed way to prevent dementia. However, the discussion highlighted good sleep and building cognitive reserve as two areas people can focus on when thinking about long-term brain health.
This does not mean that following a perfect lifestyle can guarantee protection from dementia or other brain conditions. Instead, it shows how everyday choices can form part of a broader approach to keeping the brain healthy.
Brain Health Should Not Become Another Source of Stress
There is also an important balance to remember. Trying to optimise every part of health can sometimes become stressful in itself. Brain health should ultimately help people live a fulfilling life, not become another reason to constantly worry about whether they are doing everything perfectly.
Getting better sleep, managing stress, staying mentally active and being mindful of alcohol are useful habits. But so are joyful moments, making memories, spending time with people and enjoying life.
The broader message is simple: take care of your brain, but do not let the pursuit of perfect health stop you from living well.
