Children who miss sleep ‘at risk of obesity’

Children who do not get enough sleep are at greater risk of becoming obese, according to new research.

The researchers believe that sleep restriction leads to hormonal changes in the stomach and in fat cells that trigger increased appetite.

Professor Ed Mitchell, of the University of Auckland in New Zealand, said: “Sleep is important for health and well-being throughout life. Our results show a strong effect of short sleep duration on risk of obesity even when levels of daytime activity are adjusted for.
