There are a few things that you cant unlearn. Sorry, this is going to be one of them. You can tell the quality of a person’s health by the way they breathe. If you are in an elevator and your colleague is breathing heavily, worry about his or her health. There is nothing strenuous in using a lift and therefore no reason for breathing to be deep or laboured.
One of the possible causes could be nasal congestion. If this is a rare blocked nose, no harm no foul. If this is something that you see happening all the time, and you find yourself breathing from your mouth, you need to attend to it. Breathing regularly through your mouth can cause severe health consequences. It is not possible to breathe through your mouth and rest your tongue at the same time. The tongue, other than wagging to tell tall stories, is also the mould which your jaw and teeth used for support. Especially in the case of children, if left untreated, this can cause underdevelopment of the jaw.
Your oxygen levels fall in the body because of a blocked nasal package. Remember your body metabolises the food you need to create energy. It does this in the presence of oxygen, known as an aerobic state. The absence of oxygen can make you stop, catch your breath before you do anything further and so causing oxygen deprivation on an ongoing basis is extremely dangerous. If the partial pressure of oxygen falls below 55 mg/hg and this cause low oxygen saturation in your blood, a doctor will prescribe you oxygen supplementation through a mask. Some people who breathe through their mouth have reported oxygen saturation of less than 95% which makes them hypoxic or oxygen deprived. The next time you or someone you know has a blocked nose for longer than a few days, don’t ignore it, have it treated by a good Doctor.
