Whether running at night causes insomnia depends largely on the intensity of the workout and how close it is to bedtime. Generally, moderate-intensity evening exercise doesn't negatively affect sleep and might even improve it. However, high-intensity exercise too close to bedtime can disrupt sleep.
Impact of Exercise Intensity and Timing
-
Moderate-Intensity Exercise: Studies suggest that moderate-intensity exercise in the evening doesn't typically lead to insomnia. Some research even indicates that it can help you fall asleep faster and increase the amount of time spent in deep sleep.
-
High-Intensity Exercise: Engaging in high-intensity workouts, such as interval training, less than one hour before bed may negatively affect sleep. This type of exercise can make it harder to fall asleep and reduce overall sleep quality.
Key Factors to Consider
-
Individual Differences: Everyone responds differently to exercise. Some individuals may be more sensitive to the stimulating effects of evening workouts than others.
-
Exercise Type: Different types of exercise can have varying impacts. Aerobic activities like running may have a different effect compared to resistance training.
-
Timing: The closer you exercise to your bedtime, the more likely it is to disrupt sleep, particularly if it's high-intensity.
Recommendations
-
Avoid High-Intensity Workouts Close to Bedtime: If you prefer to run at night, avoid intense workouts within one hour of going to bed.
-
Opt for Moderate-Intensity Exercise: Choose moderate-intensity runs in the evening.
-
Monitor Your Sleep: Pay attention to how your body responds to evening exercise and adjust your routine accordingly.
In summary, moderate-intensity running at night is unlikely to cause insomnia and may even be beneficial. However, high-intensity running close to bedtime can potentially disrupt sleep patterns.
