How Can Exercise Improve Our Mental Health?
October 10th is World Mental Health Day! It’s pretty hard to imagine that there was a time not too long ago when talking openly about mental health could be considered a social faux pas. Thankfully, this is all in the past.
This change may have stemmed from a shift in society’s attitudes, with people now more accepting of mental health issues and more supportive of people with these issues. It’s a welcome change; after all, mental health is integral to overall health. As the World Health Organisation puts it, there is no health without mental health.
Let’s dive into how mental health can be improved with exercise and physical activity…
The topic of mental health is highly relevant as statistics estimate that 2 out of 5 Australians from the ages of 16 to 85 have experienced mental disorders that include social phobia, affective disorders such as depression, and substance abuse.
Current scientific evidence suggests that physical activity can help improve your mental well-being. In this regard, it’s alarming to note that 75% of Australian adults aged 18 to 64 are not sufficiently active and do not meet the physical activity guidelines.
Clearly, there is a need to get off the couch, sit less, and start moving more if we want to reap the mental benefits of exercise.
WHAT ARE THE MENTAL HEALTH BENEFITS OF EXERCISE?
Remember a time when you worked out during the day and slept soundly all night? Then you woke up full of energy, eager to face the day’s tasks. Those are just two of the many mental health benefits of exercise. Regular physical activity offers profound merits that include the following:
Improved stamina and endurance that can translate to better self-confidence.
Stress relief.
Decreased tiredness and increased mental alertness.
Improvement in mood, easing the symptoms of depression and anxiety.
Some studies show that people who exercise regularly have better mental health and lower levels of mental illness.
Some studies even suggest that exercise can significantly help prevent the onset of Alzheimer’s disease and dementia.
Research also reports that regular exercise can affect the brain’s neuroplasticity or the brain’s ability to reorganise synaptic connections due to learning, experience, or in the aftermath of an injury.
HOW DOES EXERCISE HELP MENTAL HEALTH?
At the very least, exercise can provide a healthy distraction from our worries. It can improve our moods through exercise-induced blood circulation to the brain.
Biologically, physical activity can also help release chemicals in the brain, including the neurotransmitters serotonin, dopamine, and endorphins.
Serotonin helps regulate our moods and sleep patterns and controls our sexual desires.
Dopamine lets us feel pleasure, satisfaction, and motivation.
Endorphins interact with receptors in the brain that can trigger positive feelings and reduce our perception of pain.
There are also studies suggesting that physical exercise may be able to influence the production of neurotrophic factors that provide improved brain functionality.
‘Neurotrophic factor’ is a term that points to the ability of a factor to support or nourish the growth of neurons. This is related to the ability of exercise to improve the brain’s neuroplasticity.
