Since the outbreak of Covid-19 face mask has become a necessity when going out or when in the midst of crowd.
However, as good it is for the prevention of Covid-19 there are also side effects that come with wearing face mask.Face masks make breathing more difficult,” points out Lazzarino in his letter. “For people with COPD”—that’s chronic obstructive pulmonary disease, which causes a decreased air flow—”face masks are in fact intolerable to wear as they worsen their breathlessness. Moreover, a fraction of carbon dioxide previously exhaled is inhaled at each respiratory cycle. Those two phenomena increase breathing frequency and deepness, and hence they increase the amount of inhaled and exhaled air.”
The CO2 will slowly build up in the mask over time. However, the level of CO2 likely to build up in the mask is mostly tolerable to people exposed to it. You might get a headache but you most likely [would] not suffer the symptoms observed at much higher levels of CO2. The mask can become uncomfortable for a variety of reasons including a sensitivity to CO2 and the person will be motivated to remove the mask. It is unlikely that wearing a mask will cause hypercapnia
Wearing of facemask for make the exhaled air to go into the eyes. This generate an uncomfortable feeling and an impulse to touch your eyes. If your hands are contaminated, you are infecting yourself ( Greenhalgh et al)
The body need certain level of oxygen to keep it energetic. Wearing of facemask reduce the amount of oxygen going into the body system thereby making one feel tired. Body tiredness thereby bring the urge to remove the facemask to receive enough oxygen to keep the body energetic. That is why you always find it difficult to Wear facemask for long time.
It is imperative to be careful when wearing facemask and ensure you go out when it is only necessary, since wearing of facemask has its side effects, also you can’t wear it for longtime before having urge to remove it, and if removed amidst crowd could expose one to the risk of contracting Covid-19
