The sleep well eating plan

"Getting a good night's sleep should be as natural as taking in air, water and food. So, if you spend most nights tossing and turning, you need to make changes to your lifestyle and your diet," says Jane Worthington, author of 'The Duvet Diet' (Rodale, £9.99). "The philosophy is simple: the better you eat, the better you'll sleep. And vice versa." She adds: "Sleep deprivation can also cause your metabolism to slow down, resulting in weight gain. And if you're tired, you're more likely to reach for biscuits to wake you up, when what you really need is a decent rest."

The rules

● Establish a sleep routine that ensures you go to bed and set your alarm at the same time every day. This will train your brain to know when it's time to rest, making it far easier for you to fall asleep.

● Understand the risks of sleep debt. This not only includes weight gain, but also diabetes, concentration and memory loss, depression, mood swings and anxiety.

● Beat the sleep saboteurs. These include cigarettes, alcohol and coffee, which can dramatically impair the quality of your sleep.

● Wear socks in bed. They may be a passion killer, but according to The Lancet, you'll fall asleep faster and more deeply than non-sock wearers. And good circulation means a better quality of sleep.

● Drink a cup of Horlicks or semi-skimmed milk two hours before bed. Dairy foods are a good source of tryptophan, an amino acid that your body converts into melatonin and serotonin, both of which help to induce sleep.

● Limit the carbohydrates in your evening meal to help prevent glucose, insulin and other hormonal surges that can rob you of restful sleep.

● Take a valerian supplement (£4.84 for 90 tablets; www.justvitamins.co.uk), known for its sleep-promoting effects.
