We all know that getting sufficient exercise is important for all-round health and wellbeing. That includes helping you sleep better. However, while getting a sweat on during the day will help you improve your sleep quality when bedtime rolls around, you do need to be careful about exactly when you fit in that workout. 

Just as there’s an optimal time to stop drinking before bed, with exercise, it’s all about timing. And that’s especially true if you’re going for a high-intensity session. We spoke to Dr Verena Senn, neurobiologist and head of sleep research at Emma sleep (the brand behind the best memory foam mattress around, in our opinion) about when you should stop exercising before bedtime for the best sleep.

“When considering how close to your bedtime you should be exercising largely depends on the type of physical activity. For example, high-intensity late-night exercise has been shown in some studies to delay sleep onset on account of an increased heart rate,” says Dr Verena. “For most people, I would recommend not exercising in the two hours before bed.”

What kind of exercise is it okay to do before bed?

If later in the evening is the only time you can squeeze in your exercise, it’s best to stick to calming, non-cardio activities. “Something like that is lower-impact, such as yoga when used more like a meditative practice, can be very helpful to sleep,” explains Verena. Try these yoga stretches to do before bed, or some breathing exercises to help chill you out.

“By encouraging slower breathing and activating the parasympathetic nervous system (PSNS), this kind of exercise can increase the concentrations of the neurotransmitter GABA (sometimes known as the brains tranquilliser) and relax the mind and muscles,” says Dr Verena.

When it comes to exactly how much exercise to do, there’s no hard-and-fast rule, as it varies a lot depending on your age, abilities, fitness level and so on. “Whatever you do, stick to a routine and learn what works for you,” she continues. “It’s not one size fits all; identify your own preferences and observe whether the timing of your exercise promotes or inhibits your sleep.”

Remember, too, that exercise is just one part of a wider sleep hygiene regime. “It’s recommended that healthy adults get between 7-9 hours of sleep a night, so whatever your levels of exercise this is something to aim for,” continues Dr Verena (although some experts disagreeat #7 in our 24 tips for better sleep, independent sleep consultant Dr Neil Stanley says that how much sleep you need is genetically determined, and actually anything before four and 11 hours could be right for you).
