Best Exercise for Sleep: Duration, Intensity, Type and Timing Explained
Sleep and exercise are closely connected. At Active Answers Health in Seaforth, we often see people whose sleep improves once they begin moving more consistently and building a simple exercise routine.
Many people start exercising to get stronger or fitter, but one of the first benefits they notice is better sleep. They fall asleep faster, sleep more deeply and wake feeling more refreshed.
The good news is you don’t need extreme workouts or complicated routines. Research shows that the duration, intensity, type and timing of exercise all influence sleep quality. When you get those roughly right, even simple movement can make a big difference.
Watch the short talk below where I explain how exercise improves sleep and what the research shows.
This video was recorded during our Sleep Workshop at Active Answers Health in Seaforth, where we discussed how exercise can improve sleep quality, sleep duration and recovery.
How long should you exercise for better sleep?
You don’t need long workouts to improve sleep.
Research comparing different exercise durations shows that around 30 minutes of moderate exercise can improve sleep quality by roughly 20–30%. Increasing this to about 60 minutes may improve sleep quality by around 35–40%, but going longer than that doesn’t add much extra benefit.
Exercise has also been shown to help people fall asleep around 10–15 minutes faster, improve sleep efficiency, and increase total sleep time.
For most people, aiming for 30–60 minutes of exercise on most days is enough to see meaningful improvements in sleep.
What intensity of exercise works best?
You don’t have to train flat out to sleep better.
Even low-intensity exercise improves sleep quality. Higher intensity exercise can produce slightly greater improvements, but the sweet spot for most people is moderate intensity exercise.
This is the level where you are breathing a little heavier but can still comfortably hold a conversation. Many people refer to this as Zone 2 exercise, which is roughly 50–70% effort.
Moderate exercise tends to support better sleep without overstimulating the body.
What type of exercise helps sleep the most?
The good news is that almost any type of movement can help.
Cardio exercise such as walking, cycling or running has been shown to increase deep sleep. Strength training also improves overall sleep quality compared with people who don’t exercise.
Even something as simple as daily walking can reduce night-time waking and improve sleep quality.
For the best results, combining cardio and strength training tends to work well. For example:
Walking plus strength exercises
Cycling plus resistance training
Running plus gym work
More important than the exact activity is choosing something you enjoy and can do consistently.
What time of day should you exercise?
Exercise at almost any time of day can improve sleep.
Morning exercise can help regulate your body clock. Midday or early evening sessions often work well because your body temperature and physical performance are naturally higher.
Where people sometimes run into trouble is with very intense exercise late at night, which can keep the nervous system stimulated and delay sleep.
As a general guide, it helps to finish exercise about 60–90 minutes before bed, giving your heart rate and body temperature time to settle.
A simple exercise approach for better sleep
If your goal is better sleep, the routine doesn’t need to be complicated.
Exercising 3–5 days per week, aiming for 30–60 minutes per session, keeping the intensity moderate, and combining cardio with some strength training is a very effective approach.
Consistency matters more than perfection. Even small increases in regular movement can make a noticeable difference to sleep quality.
FAQ's
Both cardio and strength training improve sleep. Activities like walking, cycling and running can increase deep sleep, while resistance training improves overall sleep quality. A combination of both tends to work best.
Around 30–60 minutes of moderate exercise on most days is usually enough to improve sleep quality.
Moderate intensity exercise works well for sleep. This means exercising at about 50–70% effort, where you are breathing slightly harder but can still talk comfortably.
Very intense exercise right before bed can delay sleep for some people. Finishing workouts 60–90 minutes before bedtime usually allows enough time for the body to settle.
Yes. Regular walking has been shown to reduce night-time waking and improve sleep quality. For many people it’s one of the easiest ways to start improving sleep.
