Is ten degrees Celsius inside a house a dangerous temperature for health? Is it too low to bear continuously? In principle, when one thinks of excessive cold for the human condition, one does not imagine a room in those conditions, but rather an open field in the middle of the Siberian steppe or Antarctica. However, such an environment in a home can mean a real challenge for the body.
He has verified it in his own body BBC journalist James Gallagher and he has captured it in an article thanks to an experiment carried out together with Professor Damian Bailey, from the University of South Wales. The test consisted of staying in an originally isolated room at 21 degrees whose temperature It was going down to 10while investigators monitored the reporter’s vital signs.
Initially, the editor was comfortable in an environment of 21 degrees, in which he even began to sweat. There he began the work of cooling. When he reached 18, his body had already stopped perspiring and the hair on his arms had begun to stand on end to help you isolate yourself from the outside. It was, according to Bailey, a “tipping point” in which the body works to maintain core temperature.
As he continued down, his fingers turned white and felt cold: blood vessels were closing, in a process known as vasoconstriction, to keep blood warm in critical organs. This is a mechanism that occurs even earlier in women.
Upon reaching ten degrees, the journalist was “very uncomfortable” and perceived how his brain had a harder time doing some simple tasks, such as completing shape sorting games. This is because, Bailey points out, less blood reaches the brain and therefore has less oxygen and glucose.
This situation also generated a cardiovascular risk for the editor, as blood pressure shot up to pump blood, which had become thicker and stickier. “The evidence clearly suggests that cold is more deadly than heat, there are higher numbers of deaths caused by cold waves than heat waves,” says the University of Wales professor.
