Hot flashes are one of the most common and distressing symptoms of perimenopause and menopause, affecting up to 80% of women. (Freedman, 2014) These sudden sensations of intense heat can disrupt sleep, trigger anxiety, and impact overall quality of life. While hormonal changes are the primary driver of hot flashes, research suggests that the vagus nerve plays a crucial role in their intensity and frequency.
The Vagus Nerve and Hot Flashes: A Surprising Connection
The vagus nerve, a key component of your parasympathetic nervous system (PNS), is responsible for regulating many bodily functions, including heart rate, digestion, and even your body's inflammatory response. (Porges, 2011) Studies have shown that hot flashes are associated with increased heart rate and decreased vagal activity. (Carpenter et al., 2013) This means that during a hot flash, your "fight-or-flight" sympathetic nervous system takes over, leading to the characteristic symptoms of heat, sweating, and heart palpitations.
Vagal Dysfunction in Menopause
While the vagus nerve plays a role in hot flashes, its influence extends beyond these acute episodes. During menopause, the vagus nerve may become less robust, leading to a greater sensitivity to stress, disruptions in circadian rhythms, sleep difficulties, and other challenges. (Soares et al., 2016) This vagal dysfunction can contribute to a range of menopausal symptoms, including:
- Hot flashes and night sweats: These sudden surges of heat are often accompanied by sweating and heart palpitations, disrupting sleep and daily activities are linked to decreased HRV (Heart rate variability) or low vagal tone.
- Mood swings: The vagus nerve is involved in regulating mood and emotions. Decreased vagal activity can contribute to irritability, anxiety, and depression.
- Heart palpitations: Changes in heart rate and rhythm can be a common experience during menopause, often linked to decreased vagal control.
- Blood pressure fluctuations: The vagus nerve helps regulate blood pressure. Dysfunction can contribute to fluctuations and increase the risk of cardiovascular issues.
Breathing Your Way to Relief: The Power of Breathwork
The good news is that you can harness the power of your breath to calm hot flashes and improve vagal tone. Deep, slow breathing techniques, especially those that emphasize a long exhale, have been shown to stimulate the vagus nerve and promote relaxation. (Gerritsen & Rijken, 2016)
- Paced Respiration: This technique involves breathing at a controlled rate, typically around 6 breaths per minute. Research suggests that paced respiration can help alleviate hot flashes and improve overall well-being during menopause. (Harvard Health Publishing, 2018)
- Cyclic Sighing: This type of breathwork involves taking two inhales followed by a long exhale. Studies have shown that cyclic sighing is particularly effective at improving mood, reducing respiratory rate, and promoting a sense of calm. (Bernardi et al., 2023)
Beyond Hot Flashes: Vagal Tone and Menopausal Health
The benefits of improving vagal tone during menopause extend far beyond just managing hot flashes. A strong vagus nerve can help:
- Reduce inflammation: Vagal modulation of inflammation can act on specific inflammatory molecules to moderate midlife inflammatory processes, which are linked to various health issues. (Matias et al., 2021)
- Improve mood and reduce anxiety: To mitigate the mood instability often experienced during perimenopause, it's crucial to support the vagus nerve. A healthy vagus nerve can counteract the mood-disrupting effects of chronic inflammation, which is strongly linked to depression and anxiety.
- Enhance sleep quality: A well-functioning vagus nerve supports healthy sleep patterns, which are often disrupted during menopause. Stimulating the vagus nerve, by regulating the parasympathetic nervous system, enhance sleep quality and address issues like insomnia by promoting relaxation and improving sleep architecture
- Increase resilience to stress: A strong vagal tone helps you cope with stress more effectively, which is particularly important during the hormonal shifts of menopause. By strengthening your vagal tone, you're not just reacting to stress, but proactively building resilience. This means you can better navigate daily challenges, recover more quickly from stressful events, and experience a greater sense of calm and well-being.

FAQs
Why do hot flashes happen during menopause or perimenopause?
Hot flashes are caused by hormonal fluctuations—particularly declining estrogen—that affect the hypothalamus, the brain’s thermostat. This can trigger sudden heat sensations, sweating, and heart palpitations. Stress and sympathetic nervous system activation can make hot flashes more frequent or intense.
How can breathwork help reduce hot flashes?
Breathwork activates the parasympathetic nervous system and stimulates the vagus nerve, which helps calm the body and reduce sympathetic overactivation. Slow, controlled breathing—especially around 0.1 Hz (6 breaths per minute)—can lower heart rate, steady temperature regulation, and lessen the intensity of hot flashes.
What type of breathwork is most effective for hot flashes?
Resonant breathing or paced breathing at approximately 6 breaths per minute is ideal. Focus on slow inhalations and slightly longer exhalations. Practicing for 5–10 minutes several times a day can improve nervous system balance and reduce the frequency and severity of hot flashes over time.
Can breathwork be used alongside other menopause strategies?
Yes. Breathwork complements lifestyle strategies such as maintaining a balanced diet, staying hydrated, exercising, and managing stress through mindfulness or meditation. Combining approaches maximizes parasympathetic activation and helps stabilize body temperature and hormonal responses.
Tools like Seesaw Health’s Egg biosensor can monitor physiological responses such as heart rate variability (HRV) and stress levels in real time. Tracking your body’s response helps you optimize breathwork, see improvements, and identify triggers that worsen hot flashes.
