High-intensity exercise before bedtime may have been a common habit for many fitness enthusiasts, but a recent study has shown that this could have far-reaching consequences on our sleep quality. The study, which was conducted by researchers at Monash University in Melbourne, found that exercising four hours or less before bedtime can lead to disrupted sleep patterns.
- More than 14,000 participants were tracked over a year
- The study adjusted for various factors such as age, fitness level, and sleep quality to ensure accurate results
The research aimed to investigate the impact of exercise on sleep patterns, and how this can be affected by the timing of physical activity before bedtime. The study involved an international sample of 14,689 people wearing a multi-sensor biometric device to record exercise, sleep, and cardiovascular data over one year.

The researchers analyzed the data and found that high-strain activities, such as HIIT (high-intensity interval training) workouts, football and rugby games, or a long run, had the biggest impact on sleep patterns. These activities led to sustained increases in breathing rate, core body temperature, heart rate, and mental alertness, which can make it difficult to fall asleep. “If exercising within a four-hour window of bedtime, people could choose brief low-intensity exercises, such as a light jog or swim, to minimize sleep disruption and allow the body to wind down,” said Dr. Josh Leota, the first author of the study from the Monash University School of Psychological Sciences.
“This study highlights the importance of timing of physical activity in relation to sleep. It’s essential to balance our physical activity with rest and relaxation to maintain good sleep quality.”
In addition to the health benefits of regular exercise, it’s also essential to establish a relaxing bedtime routine to signal to the body that it’s time to sleep. This can include activities such as reading, meditation, or a warm bath. What is HIIT?
HIIT is a type of workout that involves short bursts of high-intensity exercise followed by brief periods of rest. This type of exercise has been shown to be effective in improving cardiovascular fitness, increasing muscle strength, and boosting metabolism. Why is timing of physical activity important?
The timing of physical activity can have a significant impact on our sleep patterns and overall health. Exercising too close to bedtime can disrupt our natural sleep-wake cycle, leading to fatigue, decreased productivity, and a range of other negative effects.
• HIIT (High-Intensity Interval Training): A type of workout that involves short bursts of high-intensity exercise followed by brief periods of rest. • Sleep disruption: The disturbance of normal sleep patterns, leading to fatigue, decreased productivity, and other negative effects. • Biometric data: Measurements of an individual’s physical and biological responses, such as heart rate, breathing rate, and body temperature, used to monitor exercise, sleep, and cardiovascular data.
By understanding the impact of exercise on sleep patterns, we can take steps to maintain good sleep quality and overall health.
