Strength Training for Hot Flashes During Perimenopause: A Counterintuitive Remedy
Strength training may seem like an unlikely fix for hot flashes, but evidence shows it can reduce frequency and severity. Here is how to make it work.
Why Hot Flashes Happen and What Makes Them Worse
Hot flashes are the hallmark symptom of perimenopause, affecting around three quarters of women at some point during the transition. They arise because declining oestrogen levels disrupt the hypothalamus, the brain's thermostat. The thermoneutral zone, the comfortable range of core temperatures the body tolerates without triggering cooling responses, narrows dramatically. Small rises in core temperature prompt an immediate and disproportionate reaction: rapid vasodilation in the skin, increased heart rate, sweating, and a wave of intense heat lasting anywhere from seconds to several minutes. Several factors worsen hot flash frequency: high stress levels, poor sleep, excess body weight, smoking, alcohol, and a sedentary lifestyle. This last factor is significant because it means that exercise, done correctly, can be a genuine and practical tool for reducing the burden of hot flashes over time.
The Case for Strength Training Specifically
Strength training is not the first intervention most women think of when looking to reduce hot flashes, partly because the exertion involved does raise core temperature temporarily. However, the long-term effects of consistent resistance training on hot flash frequency are meaningfully positive. Regular strength training improves body composition, reducing adipose tissue that generates excess metabolic heat. It increases insulin sensitivity, which reduces the metabolic dysregulation that can worsen thermoregulatory instability. It also builds muscle mass that tends to decline rapidly in perimenopause, protecting against metabolic syndrome and reducing one of the inflammatory drivers of hot flash severity. Crucially, women who exercise regularly show better autonomic nervous system regulation, which means their bodies handle temperature variation with less of an exaggerated response. Over weeks and months, strength training essentially recalibrates the thermostat toward greater stability.
Specific Approaches That Work Well
The key for perimenopausal women managing hot flashes through strength training is temperature management during the session. Train in a cool, well-ventilated space. Keep a small fan aimed at your face and neck. Wear moisture-wicking, breathable clothing. If a flush begins mid-session, pause, take slow deep breaths, and apply a cool cloth to the back of the neck before continuing. For programming, compound movements such as squats, deadlifts, rows, and presses give you the most metabolic benefit per minute of training. A programme of two to three strength sessions per week, each lasting 30 to 45 minutes, is sufficient to produce both the body composition and autonomic benefits linked to hot flash reduction. Rest intervals of 60 to 90 seconds between sets allow partial core temperature recovery and make the session more manageable. Start at a moderate intensity, around 60 to 70 percent of your estimated maximum, and progress gradually over several weeks.
Evidence Supporting Strength Training for Hot Flash Relief
Research on resistance training and hot flashes is increasingly robust. A 2014 study published in Menopause examined women with frequent hot flashes who followed a 15-week strength training programme and found significant reductions in both frequency and severity compared to a control group. Broader research into exercise and vasomotor symptoms, the clinical term for hot flashes and night sweats, consistently shows that physically active women experience fewer and less severe episodes than sedentary women. The SWAN study, one of the largest longitudinal studies of perimenopause, found that regular vigorous exercise was associated with a lower risk of bothersome vasomotor symptoms. Weight loss from resistance training, where relevant, also independently reduces hot flash burden. Even modest improvements in body composition, five to eight percent reductions in body fat, have been shown to reduce hot flash frequency in overweight perimenopausal women.
Getting Started Safely and Sustainably
If you are new to strength training, start with bodyweight exercises at home before moving to a gym. Squats, lunges, press-ups, hip hinges, and rows using resistance bands can all be done without equipment and are genuinely effective for building the baseline strength needed to progress. Free online programmes designed for women beginning strength training in midlife are widely available. If you prefer a gym, consider a session or two with a personal trainer who has experience working with perimenopausal women. Let them know about your hot flashes so they can structure the session appropriately. Avoid training in hot or humid environments if your hot flashes are severe. Build sessions into your week at consistent times, as regularity drives the long-term nervous system adaptations that reduce hot flash frequency. If you are also using hormone therapy, you may find that symptoms improve enough to train at a slightly higher intensity over time.
Using Tracking to Measure Real Progress
Hot flash patterns are highly individual and influenced by numerous variables. Without recording your activity and symptoms consistently, it is difficult to know whether strength training is genuinely helping or whether your experience is fluctuating for other reasons. The PeriPlan app lets you log workouts and track symptoms including hot flash frequency and severity over time. This means you can review weeks or months of data and notice whether periods of consistent training correlate with fewer or less intense flushes. Over six to 12 weeks, patterns typically become clear enough to draw meaningful conclusions. This logged information is also valuable to share with a GP or menopause specialist, providing an evidence base for what lifestyle interventions are and are not working before discussing further treatment options.
