Is HIIT Good for Depression During Perimenopause?
Perimenopause depression is hormonally driven and difficult. HIIT can trigger powerful mood-lifting effects, but timing and dosage matter. Here is what to know before you start.
Depression in Perimenopause Has a Hormonal Root
Depression is one of the most significant but least discussed aspects of perimenopause. Women with no previous history of depression can find themselves experiencing persistent low mood, emotional numbness, and loss of interest in things they used to enjoy. This is directly tied to fluctuating and declining estrogen, which disrupts serotonin and dopamine regulation. It is a physiological event, not a personal failing. Exercise, particularly vigorous exercise like high-intensity interval training, is one of the most evidence-backed interventions available for depression, and it works through overlapping but complementary mechanisms to antidepressants.
Why HIIT Is Effective for Depression
High-intensity interval training triggers a large release of endorphins, brain-derived neurotrophic factor (BDNF), and dopamine. BDNF is sometimes called the brain's growth hormone. It promotes the growth of new neurons in the hippocampus, a region that physically shrinks with chronic depression. Research shows that just 20 to 30 minutes of high-intensity exercise produces BDNF levels comparable to those achieved with antidepressant medication. The effect builds over time with regular practice, and many women report that their emotional resilience, their ability to bounce back from difficult moments, improves noticeably after several weeks of consistent HIIT.
The Caveat: HIIT Can Backfire if You Are Depleted
There is an important nuance here. If your depression is severe, if you are deeply exhausted, sleeping poorly, and barely functioning, launching into intense exercise can raise cortisol and make things temporarily worse. HIIT is best suited to women who are experiencing low to moderate depressive symptoms and have some baseline energy. If you are in a more severe episode, gentler movement like walking or yoga may be a better starting point. The goal is to build up to HIIT as your energy and mood improve, not to force yourself through sessions that leave you feeling worse.
How to Structure HIIT for Mood Benefits
You do not need long sessions. Research suggests that 20 to 25 minutes of true HIIT, meaning intervals where your heart rate reaches 80 to 90 percent of maximum, is sufficient to trigger the neurochemical effects that benefit mood. Two to three sessions per week is optimal. More than that risks overtaxing the adrenal system, which is already under stress during perimenopause. Workouts can include cycling, bodyweight circuits, rowing, or any format you enjoy. Recovery days are not optional; they are where adaptation and mood stabilisation actually happen.
Combining HIIT with Other Depression Strategies
HIIT works best as part of a broader approach. Sleep quality has a profound effect on depression, and the good news is that regular vigorous exercise improves sleep. Reducing alcohol, which is a depressant and disrupts sleep architecture, is another high-impact change. Social connection is also protective against depression, so group fitness classes can be particularly valuable. If your low mood has persisted for more than two weeks and is affecting your ability to function, please speak to your GP. Hormone therapy, talking therapies, and medication all have strong evidence for perimenopausal depression.
Tracking Progress Over Time
The effects of exercise on depression are cumulative and take time to build. You may not notice a dramatic shift after a single session, though many women do feel a short-term lift. The sustained benefits emerge after several weeks of consistent training. Keeping a simple log of your mood and energy levels can help you see patterns that are hard to notice day to day. Looking back over a few weeks and seeing that your low periods are less frequent or less intense is meaningful evidence that what you are doing is working.
