Is HIIT Good for Anxiety During Perimenopause?
HIIT can reduce perimenopause anxiety, but done wrong it can make things worse. Here is how to use high-intensity training to calm your nervous system, not overwhelm it.
Anxiety in Perimenopause: The Hormonal Trigger
Perimenopause anxiety often appears without warning in women who have never been anxious before. Falling progesterone removes one of the body's natural calming influences, since progesterone has a GABA-like effect on the nervous system. Fluctuating estrogen makes the amygdala more reactive, increasing threat sensitivity and the tendency to scan for danger. The result is a nervous system that is chronically on edge, producing racing thoughts, physical tension, heart palpitations, and a sense of impending doom that does not match external circumstances. Exercise is one of the most effective ways to rebalance this nervous system dysregulation.
How HIIT Helps with Anxiety
HIIT works for anxiety through several mechanisms. First, it burns off the excess adrenaline and cortisol that anxiety generates, providing a physical outlet for the fight-or-flight response that anxious thoughts keep triggering. Second, the cardiovascular stress of HIIT trains the body to tolerate and recover from physical arousal more quickly, which over time makes anxious physical sensations like a racing heart less alarming. Third, the endorphin and serotonin release following a HIIT session produces a measurable anxiolytic effect that can last for hours. Regular HIIT practitioners often report a calmer baseline nervous system over weeks of consistent training.
The Risk: When HIIT Worsens Anxiety
HIIT generates a significant stress response in the body. For women whose cortisol is already chronically elevated due to perimenopause, poor sleep, or life stress, adding intense exercise on top can tip the system further into overload. The key distinction is whether you are anxious and depleted or anxious but not exhausted. If you are the former, starting with lower-intensity exercise and building gradually is wiser. If you attempt HIIT and feel more wired, agitated, or worse in the 24 hours following, that is a signal to reduce intensity or frequency, not to push through.
Timing Your HIIT Sessions
When you train matters as much as how you train for anxiety management. Morning HIIT sessions tend to work better for most perimenopausal women because the cortisol spike from exercise aligns with the natural morning cortisol peak, rather than disrupting the evening wind-down when cortisol should be falling. HIIT within three hours of bedtime can impair sleep quality, and poor sleep is one of the biggest drivers of next-day anxiety. Aim for morning or early afternoon sessions and allow yourself an evening routine that prioritises rest and recovery.
A Practical Starting Protocol
If you are new to HIIT or have been managing anxiety, start with two sessions per week of 20 minutes each. A basic structure might be 30 seconds of effort at 80 percent of maximum followed by 60 to 90 seconds of easy movement, repeated eight to ten times. Prioritise formats you enjoy: cycling, bodyweight circuits, rowing, or aerobics-style cardio all qualify. Add a third session after four weeks if the first two are leaving you feeling better rather than worse. Never sacrifice sleep or recovery for extra training sessions.
Supporting HIIT with Broader Anxiety Care
HIIT is a useful tool but anxiety during perimenopause deserves a multi-pronged approach. Reducing caffeine and alcohol, both of which directly amplify anxiety, is highly effective. Magnesium glycinate is often recommended for its calming effects and is commonly low in perimenopausal women. If anxiety is significantly affecting your daily life, your GP can discuss whether hormone therapy, beta-blockers, SSRIs, or talking therapies like CBT might be appropriate. HIIT works best as one piece of a broader strategy rather than a standalone solution.
