Exercise as part of a healthy lifestyle is still one of our best defences.

One of the best things you can to boost your immune System and prepare your body to fight disease is exercising.

If exercise was a pill it would be regarded as a wonder drug, the best medicine, so powerful are its known effects to improve everything from general wellbeing to musculoskeletal disease to cardiovascular problems to diabetes, multiple sclerosis, mental health, anxiety and depression.

So, aside from getting stronger and fitter, here are three big reasons to keep exercising – or to start if you aren’t already.

Support your immune system
It’s simple – being physically fit increases your immunological fitness too. Basically, exercise increases blood flow and mobilizes white blood cells, one of the main defences against harmful microbes. At least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous exercise per week is recommended, but anything is better than nothing. A study found that just 30 minutes of brisk walking increased the circulation of natural killer cells and other immune system warriors in the blood.

Improve your mental health
Stress hormones compromise immune function but exercise, including yoga, is very good at combatting stress. Numerous studies have shown that regular physical activity is associated with better mental health, including a reduced risk or incidence of dementia, reduced feelings of anxiety and depression, improved cognitive function, improved quality of life, improved sleep.

In short, exercise is really good for you, so keep it up.
