We have no voluntary control over how much or when we sweat – it’s all down to the vagaries of the English summer
Writing on the hottest day of the year so far, sweat was never going to be very far from my mind. This is literally true: our brains are connected to every one of the innumerable sweat glands in our skins by neural pathways.
This regulation means that our evaporation cooling systems can respond to temperature changes very rapidly. No matter how hard we may try, we have no voluntary control over how much or when we sweat – these responses are controlled by the hypothalamus, clusters of nerve cells near the base of our brains.
