Where does oxygen come from in winter if plants do not photosynthesize?

Since the Earth's atmosphere mixes well enough, there is no noticeable decrease in the amount of oxygen at different points. In addition, the human body is able to adapt to an insufficient amount of oxygen (for example, already at an altitude of 1000 meters, the pressure is already 670 mm Hg), increasing the depth and frequency of breathing.

It's not about the concentration of oxygen, and in the concentration of carbon dioxide. An increase in the proportion of carbon dioxide dissolved in the blood leads to a decrease in the proportion of oxygen. In a cold winter and a primitive window ventilation system, you have to ventilate the room much less often, which leads to very high concentrations of carbon dioxide in the premises (2-5 higher than outside). Such living conditions, if it is not enough to leave the house, lead to constant drowsiness and even headaches. The correct ventilation mode (every 4 hours) is possible only with good heating, since correct ventilation is usually accompanied by a decrease in the room temperature by 2-3 degrees (accordingly, the room should be warmed up by these 2 degrees in 4 hours).

no, this is a delusion. oxygen does not become less or more. if such an end comes to humanity. cold compresses blood vessels because of this, blood circulation deteriorates, as a result, the exchange of oxygen in the blood slows down and impairs our activity in general and in the brain.
