The best offers for running courses from Simple Run for our subscribers - https://simplerun.ru/ytpromo When running at low temperatures, there is a risk of catching a cold in your throat if you breathe through your mouth, or in your lungs if you breathe deeply. Therefore, in principle, it is better to run on a track and in an indoor arena at -10. However, most of us know that people can run even in the most severe frost. The fact is that the air we inhale in the lungs becomes almost equal to the body temperature. Explanation: The full capacity of the lungs is 5 liters, they occupy most of the chest volume. But we use only 1/10 of this volume when breathing. A normal inhalation and exhalation is about 0.5 liters (the so-called respiratory volume). Thus, the inhaled frosty air is diluted almost 10 times. If we inhale air at -10C, then its temperature in the lungs will still be more than +30C. When it is -30 outside, we instinctively breathe shallowly, since breathing deeply threatens respiratory diseases (bronchitis, pneumonia, etc.). Now that we have learned about our breathing, I suggest solving a problem. Calculate how much air a person inhales on average per day. Let me remind you once again that one breath is half a liter. You have all the rest of the information. Choose the correct answer in the poll and write in the comments how you calculated it. How much does air weigh? Air has weight. One m3 of air at room temperature weighs 1.2 kg. A cubic meter of cold air weighs more, and the colder it is, the more the air weighs. For example, at -100C the difference with room temperature air will be more than 10%. When it is -30 outside, we instinctively breathe shallowly, since breathing deeply threatens respiratory diseases (bronchitis, pneumonia, etc.) //Example: water in small sips//. I can illustrate this by taking the deepest possible breath. It is about 2 liters of air.
