A regular bedtime and relaxing wind-down routine can help programme your body clock for sleep. Consider a warm bath or some gentle stretching to prepare you for bed. While fresh air and exercise during the day is great, avoid evening exercise as it has a stimulating effect. Overeating late in the day can also interfere with sleep, so try to keep evening meals light. Finally, while a hot drink is a great way to round out your bedtime routine, it’s best to cut out caffeine from noon onwards.
