Just 30 minutes of exercise a day keeps the doctor away
Our increasingly busy lifestyles and work commitments often seem to get in the way of engaging in physical activity. If you’re looking for motivation to work up a sweat then science may just be the inspiration you need.
A recent review paper has shown how exercise is beneficial for the human body to cope with stress. Stress can lead to hypertension, affects the immune system and heart. The amount of stress someone’s body is exposed to depends on the physiological stress response – which is regulated by the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. Exercising helps the body to adapt to stress at hormonal and neurochemical levels.
Another publication by Harvard Heart Letter points out most age-related diseases, such as Alzheimer’s, heart disease, diabetes and Parkinson’s are associated with the health of our mitochondria. Exercise acts on the mitochondria and also reduces inflammation. Inflammation is also linked to the pathology of most age-related diseases.
Still not motivated to go to the gym, or do a triathlon?… The good thing is that we don’t need to become a gym junkie or elite sportsmen to feel the benefits of exercising. Science suggests a mere 30 minutes of exercise – that could be just a walk – on most days is sufficient. So grab a buddy, dust off the runners and get amongst it! However you choose to get active the health benefits of regular exercise are guaranteed.
“If we had the ability to put what exactly exercise does for us into a pill, it would worth a million dollars. The irony is that exercise itself is free” (Dr. Susan Cheng of Harvard-affiliated Brigham and Womens’s Hospital). “Copyright, President and Fellows of Harvard College. All rights reserved”.
