When it gets hotter, our body just works harder to return to its default temperature, opening the blood vessels near the skin wider to lose heat and sweat it out.
“Sweat is our key response, the one way we can cope with the heat,” Julie Davies, a professor at UCL Global Business School for Health, told Euronews.
“At a certain temperature, you can’t sweat enough to keep your body cool,” Davies said. “If you’re getting an awful lot hotter than 35 or 37 degrees, you are at risk of a heart attack or a heat stroke.”
“The proteins of the body start to denature - they stop functioning, and nerve impulses don’t work as well. The nervous system is less effective, and that’s integral to the body. It would start affecting the heart, because the heart is a muscle in itself,” Halsey said.
“If that generates an arrhythmia [an abnormal heart rhythm] and the heart is not pumping blood as effectively around the body because it’s ‘out of sync’, that could cause low oxygen levels. If oxygen levels to the brain are undefended, then you’re in real trouble.”
