Have you ever had a stressful day? Many people do in the course of their daily lives. And on these high-pressure days, they might find themselves reaching for a sugary snack. Perhaps this is part of their daily routine. Or perhaps on this particular day, their self-control is a bit low and they feel compelled to take a sugar hit.

Stress is natural. That feeling of strain or pressure is a biological response, and under the right circumstances can be a great source of motivation. However, too much stress, especially chronic stress, has been linked to sleep disruption, a higher likelihood of a stroke, heart-attack, ulcer or depression, among other things. But why should stress make a person comfort eat?

Dr Giles Yeo, a member of the BBC’s Trust Me, I’m a Doctor team, got together with scientists from Leeds University to conduct an experiment into the effect of stress on blood sugar. Dr Yeo was subjected to a stress test. In the first stage, he was forced to answer mathematical questions rapidly. In the second, he had to immerse his hand in a bath of ice-cold water for a period of time.
