Do not exercise with mask on friends
Exercise increases the body’s demand for oxygen and, at the same time, increases the output of carbon dioxide. Exercising with tight face masks creates a closed chamber of increased carbon dioxide and inadequate oxygen. The rebreathing of this expired air increases the levels of carbon dioxide in the blood, which leads to an increased acidic internal environment. The acidic environment induces physiological changes in our metabolism, increases cardio-respiratory stress, changes in the excretory, brain and nervous system and even our immune mechanisms!
A person exercising, jogging, cycling or gymming with a mask on, can hence, develop symptoms such as breathlessness, headache, dizzyness, fatigue, drowsiness and muscular weakness.
The immunity being lowered, the exerciser becomes more prone to infections. There could be an out of proportion increase in the heart rate and blood pressure, leading to cardiac overload.
There is reduction of oxygenated blood to all vital organs. The poor blood flow to the kidneys can aggravate renal problems in patients having chronic renal disease. The brain too suffers from reduction in cerebral flow. This can cause mental health issues. The elderly would become more prone to postural instability, gait changes and falls.
Hence, wearing a mask while exercising is especially dangerous for elderly persons who already have a cardio-respiratory or chronic disease. The World Health Organization (WHO) has recommended that people should NOT wear masks while exercising. more
