The health benefits of exercise for our mind and body are well documented. But did you know that exercise could lower the risks of the most dangerous COVID-19 complication?
Emerging evidence suggests that prolonged stress exposure can accelerate the ticking rate of an internal cellular clock. By doing so, stress can contribute to faster ageing and body deterioration.
