Two Easy Strategies Suggested for those Struggling to Fall Asleep Post-Workout
In the ongoing quest for a good night's sleep, exercise is increasingly being recognised as a valuable tool. However, the question of when to exercise for optimal sleep benefits has sparked debate among experts. A review of the latest research reveals that **earlier in the day, especially the morning**, may be the best time to exercise for improved sleep quality.
A study published in the Journal of Physiology suggests that morning workouts could help you sleep better, with morning exercisers reporting faster sleep onset and longer, deeper sleep compared to those who work out later[1]. This aligns with our body's natural circadian rhythms, as exercising outdoors with exposure to natural light can help regulate the wake-sleep cycle[4].
However, it's not just about the time of day. The intensity of exercise matters too, particularly when it comes to bedtime. A systematic review published in Sports Medicine agrees that vigorous exercise before bedtime can impact sleep, as it can stimulate the body with increased endorphins, cortisol, and adrenaline, making it harder to fall asleep[2]. To avoid this disruption, it's recommended to **avoid high-intensity workouts within at least 60 to 90 minutes before going to sleep**.
But this doesn't mean evening exercise should be avoided altogether. Low-intensity activities, such as yoga, Pilates, walking, or a gentle jog, can help the body wind down before sleep. These exercises promote relaxation by activating the parasympathetic nervous system, helping reduce stress and improving sleep continuity[3].
Yoga and Tai Chi, in particular, have been found to potentially enhance melatonin secretion and reduce sleep latency - the time it takes to fall asleep[4][5]. Light aerobic exercise like walking is also beneficial and can be done in the evening for relaxation[2][4].
In summary, the optimal time for exercise to improve sleep quality is generally earlier in the day, especially the morning. To ensure exercise supports, rather than disrupts, restful sleep, it's recommended to avoid high-intensity workouts within 60 to 90 minutes before bedtime and to focus on gentle, low-impact activities before sleep.

Science reveals that morning workouts can promote better sleep by facilitating faster sleep onset and longer, deeper sleep, aligning with our body's natural circadian rhythms (Journal of Physiology). However, high-intensity exercises should be avoided within at least 60 to 90 minutes before going to sleep, as they can stimulate the body and potentially disrupt sleep due to increased endorphins, cortisol, and adrenaline (Sports Medicine). Instead, low-intensity activities like yoga or walking can help the body wind down before sleep, promoting relaxation and improving sleep continuity (Journal of Sleep Research, Sports Medicine, British Journal of Sports Medicine, Sleep Medicine Reviews).
