British biologists studied the metabolism of people at high temperature and humidity and came to the conclusion that living at a constant temperature of 40 degrees contributes to a sharp acceleration of metabolism or metabolism. The results of the research were published by the British press service. Experimental Biology Society (SEB).
During the study, the scientists placed the experimenters in a specially equipped laboratory room and watched how their metabolic activity levels changed during the increase in temperature and humidity. As part of the experiment, the scientists measured the breathing rate and observed the heart’s work using an echocardiograph. Volunteers wore a mask that recorded the amount of oxygen consumed.
During the observations, the scientists found that the metabolic rate of the volunteers increased sharply when the temperatures in the laboratory ranged from 40 to 50 degrees Celsius. This occurred at both low and high humidity levels. At 40 degrees Celsius, the participants’ metabolism accelerated by about 35%, and at 50 degrees Celsius and high humidity levels this indicator increased by another 13%.
According to the study’s author, the sharp increase in metabolism could not be fully explained by the fact that the bodies of those who participated in the experiments spent more calories due to increased heart rate, breathing and more active sweating. According to the researchers, this indicates that the human body’s ability to adapt is at the limit.
Scientists note that at about 40 degrees Celsius, there may be an upper limit of the thermoneutral zone, the temperature range at which the human body spends the minimum amount of energy at rest. Biologists noted that this feature of human metabolism should be taken into account when preparing measures aimed at combating the consequences of global warming.
