Mental Health Awareness Month Feature

May is Mental Health Awareness Month. A timely reminder that mental wellbeing is not only influenced by mindset, but also by lifestyle.

One of the most underestimated tools for supporting mental health, especially in adults over 65, is something surprisingly simple: regular physical activity.

For decades, exercise has been framed primarily around physical fitness, weight management, and cardiovascular health. While these are important, emerging research in neuroscience shows a much broader truth:

Movement directly influences the brain, including mood, memory, focus, and emotional resilience.

This article explores the science behind the “brain–movement connection” and provides practical, safe, and achievable exercise strategies specifically designed for healthy ageing.

How Exercise Affects the Brain (The Science Explained Simply)

When you move your body, even at a gentle intensity, several important physiological changes occur:

1. Increased blood flow and oxygen delivery

Exercise increases circulation, delivering more oxygen and nutrients to the brain. This supports alertness, cognitive performance, and overall brain efficiency.

2. Activation of key brain regions

Brain imaging studies have shown that physical activity is associated with increased activity in areas linked to:

• Mood regulation
• Memory processing
• Attention and focus
• Emotional control

While individual scans vary, the consistent finding is increased brain activation following movement compared to rest.

3. Neuroplasticity support

One of the most important concepts in brain health is neuroplasticity: the brain’s ability to adapt, re-organise, and form new connections.

Regular movement is believed to support this adaptability, which becomes increasingly important with age.

Serotonin and Dopamine: Why You Feel Better After Movement

Exercise also influences key neurotransmitters: the chemical messengers in the brain that affect how we feel and function.

Serotonin (Mood Stability & Calm)

Serotonin is involved in:

• Emotional balance
• Calmness and relaxation
• Sleep quality
• Overall sense of wellbeing

Regular physical activity is associated with healthier serotonin activity, which may help explain why gentle exercise can improve mood and reduce feelings of stress.

Dopamine (Motivation & Reward)

Dopamine plays a role in:

• Motivation and drive
• Focus and attention
• Sense of reward and satisfaction
• Enjoyment and engagement

After movement, many people experience a subtle uplift in energy and motivation, often described as feeling “clearer” or more mentally switched on.

Why Exercise Matters Even More After 65

As we age, maintaining brain health becomes just as important as maintaining physical strength.

Regular movement may help support:

• Cognitive function and memory
• Mood and emotional wellbeing
• Balance and coordination
• Independence and mobility
• Sleep quality
• Stress resilience

Importantly, research consistently shows that consistency matters more than intensity.

You do not need high-intensity training to benefit the brain. You need regular, achievable movement.

Practical, Safe Exercise Guide

Below are evidence-informed, realistic movement options along with how and when to do them for maximum benefit and safety.

Walking (The Foundation of Brain and Body Health)

Walking is one of the most well-researched forms of exercise for healthy ageing and mental wellbeing.

How to do it:

• Aim for a comfortable but slightly brisk pace
• You should be able to talk, but not sing
• Swing your arms naturally
• Wear supportive footwear

When to do it:

• Morning walks can support energy and mood for the day
• Afternoon walks may help with stress reduction and mental clarity
• After meals (10–15 minutes) can also support digestion and blood sugar regulation

Recommended dose:

• Start with 10–20 minutes daily
• Gradually build toward 30 minutes most days of the week

Even short “movement snacks” throughout the day are beneficial.

Chair-Based Exercise (Safe Strength and Mobility Support)

Chair exercises are ideal for those who want low-impact movement or need additional stability.

How to do it:

Try a simple circuit:

• Seated leg extensions (10–12 reps each leg)
• Seated marching (30–60 seconds)
• Arm raises with light weights or water bottles
• Gentle seated torso rotations

Focus on controlled movement and posture.

When to do it:

• Morning routine to “wake up” the body
• During TV time or breaks in the day
• After long periods of sitting

Recommended dose:

• 10–20 minutes, 3–5 times per week

Gardening (Functional Full-Body Movement)

Gardening is often overlooked but is an excellent combination of strength, flexibility, balance, and coordination.

How to do it safely:

• Alternate between standing, kneeling, and sitting positions
• Use supportive tools (kneeling pads, raised garden beds if needed)
• Avoid prolonged bending. Squat or hinge at hips instead

When to do it:

• Mid-morning or late afternoon when temperatures are comfortable
• Break tasks into 20–30 minute sessions

Tip:

Treat gardening like exercise intervals - short bursts are more beneficial than long, fatiguing sessions.

Tai Chi and Gentle Stretching (Balance + Nervous System Calm)

Tai Chi is widely studied for its benefits in balance, coordination, and fall prevention.

How to do it:

• Slow, controlled movements with deep breathing
• Focus on posture and balance shifts
• Move within a pain-free range

Simple stretching can include:

• Neck rolls
• Shoulder circles
• Hamstring stretches
• Calf stretches

When to do it:

• Morning for mobility and stiffness
• Evening for relaxation and sleep support

Recommended dose:

• 10–20 minutes daily or most days

Dancing (Brain Stimulation + Joy Factor)

Dancing combines physical movement with music, activating both cognitive and emotional centres of the brain.

How to do it:

• Put on music you enjoy
• Start with simple steps or swaying
• Add arm movements and gentle turns if comfortable

No technique required! Consistency matters more than skill.

When to do it:

• Morning energy boost
• Late afternoon mood lift
• Social settings for added cognitive benefit

Recommended dose:

• 10–20 minutes, as often as enjoyable

Walking With Others (The Social Brain Advantage)

Social connection is strongly linked with mental wellbeing and cognitive health.

How to do it:

• Join a walking group
• Walk with a friend or family member
• Set a regular weekly walking schedule

Why it matters:

Combining movement + conversation may enhance mood benefits and increase adherence long-term.

A Simple Weekly Movement Framework

For most adults over 65, a balanced weekly structure could look like:

• Daily walking (10–30 minutes)
• 3–5 chair-based or strength sessions
• 2–3 gentle stretching or Tai Chi sessions
• Optional gardening or dancing as lifestyle movement

The goal is not perfection. It is consistency and enjoyment.

Final Thoughts: Movement as Mental Nourishment

Exercise should not be viewed as punishment or obligation.

From a neurological perspective, movement is one of the most effective ways to support:

• Mood
• Memory
• Cognitive clarity
• Emotional resilience
• Overall quality of life

This Mental Health Awareness Month, it may be helpful to reframe exercise not as something you “should do,” but as something you do for your future self. Especially your brain.

Even a short walk can be a powerful signal to the body:

“We are still active. We are still adapting. We are still well.”
