Is Running Good for Night Sweats During Perimenopause?
Night sweats disrupting your sleep during perimenopause? Learn how running can improve thermoregulation, reduce frequency of night sweats, and support better rest.
Why Night Sweats Happen in Perimenopause
Night sweats are the nocturnal version of hot flashes, and they are driven by the same underlying cause. Declining estrogen disrupts the hypothalamus, the part of your brain that regulates body temperature. The hypothalamus becomes oversensitive to tiny temperature fluctuations, triggering sudden vasodilation and sweating responses that were not needed. The result is waking drenched in sweat, often repeatedly through the night, with all the sleep disruption that follows.
Can Running Reduce Night Sweats?
The relationship between running and night sweats is nuanced but genuinely positive when exercise is managed well. Regular aerobic exercise improves thermoregulatory efficiency, meaning your body becomes better at managing heat both during the day and at night. Several studies have shown that physically active women experience fewer and less intense vasomotor symptoms, including night sweats, compared to sedentary women. Running also lowers overall stress, and psychological stress is a known trigger for more frequent hot flashes and night sweats.
The Timing Question: When to Run
Timing matters when it comes to running and night sweats. Running too close to bedtime can raise your core body temperature at the wrong moment, potentially triggering a night sweat episode during the early hours of sleep. Most sleep and exercise researchers suggest finishing vigorous exercise at least two to three hours before bed. Morning or early afternoon runs are ideal for women who are particularly troubled by night sweats. Your body temperature will have returned to baseline by the time you sleep.
How Running Improves Sleep Quality
Beyond the direct thermoregulatory effects, running improves sleep quality in ways that make night sweat disruption more manageable. Regular runners fall asleep faster, experience deeper sleep stages, and are less easily roused by temperature fluctuations during the night. Even when night sweats do occur, well-rested women find them easier to recover from and fall back to sleep more quickly. This indirect benefit is often underappreciated but highly meaningful in daily life.
Practical Tips for Running with Night Sweats
If you are currently sleep-deprived from night sweats, listen to your body about run intensity. Pushing hard on a poor night's sleep can backfire, raising cortisol and making symptoms worse. On difficult days, a brisk walk or easy run is far better than an intense session you cannot recover from. Stay well hydrated throughout the day, as dehydration can intensify both hot flashes and night sweats. Keep a symptom log to spot whether your night sweats reduce on weeks you run consistently.
Setting Realistic Expectations
Running will not eliminate night sweats for every woman. If your symptoms are severe and significantly affecting your quality of life, HRT and other medical treatments are worth discussing with your GP alongside your exercise routine. Running works best as one component of a broader management strategy that also considers diet, sleep environment, and stress reduction. That said, for many women, the combination of improved thermoregulation and better sleep quality from regular running does make a meaningful and noticeable difference.
