And so to bed…

Getting enough sleep is crucial to good health generally, and in terms of mental wellbeing and weight specifically.

‘Sleep deprivation affects brain function,’ says Suzie. ‘It also increases levels of the stress hormone cortisol by as much as 37% the next day.’ This not only means we feel more anxious but that we’re more likely to turn to comfort food to feel better. ‘Cortisol affects the production of our satiety hormones leptin and ghrelin,’

Suzie explains.

Make time for seven to eight hours’ sleep every night, and improve duration and quality by establishing a nightly no-screen wind-down routine, sticking to the same going-to-bed and getting-up time, and avoiding stimulants such as caffeine, alcohol and vigorous exercise in the three hours before bed.
