Why Do I Get Anxiety Before a Hot Flash?

Many women feel a rush of dread, anxiety or panic seconds before a hot flash, and that feeling is usually the flash starting, because the body's alarm response begins shortly before the heat arrives. In a lab study of 11 women by Kronenberg and colleagues, women felt a warning sensation several seconds before each flash, their heart rate rose before the heat began and adrenaline jumped about 150% during flashes. Over 14 years, the Penn Ovarian Aging study found that women with more body-felt anxiety went on to have more hot flashes. The treatments that cut flashes start with hormone therapy, the most effective option, and include the nonhormone options in the Menopause Society's 2023 statement, such as cognitive behavioral therapy (CBT) and clinical hypnosis.

Why do I feel anxious right before a hot flash?

The dread is often the first part of the hot flash. In a 1984 study in Maturitas, Kronenberg and colleagues recorded flashes in 11 postmenopausal women who had them often. The women felt a warning sensation, which the researchers called an aura, several seconds before each flash. Their heart rate climbed shortly before the flash began and peaked 10 to 20 beats a minute higher. The researchers measured adrenaline (epinephrine) in 5 of the women, and it rose about 150% during flashes.

Your body is not making it up. In the same study, what the women felt matched what the instruments recorded, both in when each flash happened and in how strong it was. The researchers said their findings fit the idea that a hot flash comes from a shift in the brain's temperature set point (the temperature your body tries to hold). They also said the adrenaline changes fit the racing heart.

That is one explanation, and the question is still open. The Penn researchers wrote that what causes hot flashes in the body is still poorly understood.

Anxiety and hot flashes are also linked over years, not only seconds. In the Penn Ovarian Aging Cohort, Freeman and Sammel followed 233 women for 14 years, starting before menopause. Women with more somatic anxiety, the kind you feel in your body as a pounding heart or shakiness, had more than three times the odds of moderate to severe hot flashes. Their anxiety scores at one yearly visit predicted flashes at the next. The link held after the researchers removed the questions about flushing and a pounding heart, so the anxiety scores were not picking up the flashes themselves. Worry-type anxiety was not linked to flashes once other factors were taken into account.

If you feel anxious, low or snappy between flashes too, that is a separate problem with its own treatments. Read our guide to the best treatments for perimenopause mood swings and anxiety.

Is it a panic attack or a hot flash?

If heat and sweat follow the dread within seconds and the whole thing fades in a few minutes, that fits a hot flash. The Menopause Society describes a hot flash as a sudden, intense feeling of heat in the upper body, especially the face, neck and chest. Each one usually lasts 1 to 5 minutes and can come with sweating, chills, anxiety and a rapid heartbeat. Night sweats are hot flashes that happen while you sleep.

The racing heart is where the two overlap, which is why they get confused. In the Kronenberg study, heart rate rose 10 to 20 beats a minute with each flash, and the faster heartbeat was followed by widening blood vessels and sweating. The heat and sweat that follow are what set a flash apart.

Mood symptoms can also come from menopause itself. The Menopause Society says mood changes may be tied to big swings in estrogen during perimenopause, although the exact mechanism isn't known.

Bring both the flashes and the anxiety to someone who knows menopause. The Menopause Society says a clinician with menopause expertise can offer special care to women with troublesome symptoms. Tell your clinical team whether the dread arrives with heat or on its own, because the answer changes which treatment fits.

What treatments help hot flashes and the dread before them?

When the dread is the start of a flash, cutting the flashes cuts the dread. The Menopause Society's 2023 nonhormone therapy position statement says hormone therapy remains the most effective treatment for hot flashes and should be considered for women within 10 years of their final period. The table covers hormone therapy and the main nonhormone options.

Our clinical team can prescribe bioidentical estrogen if it fits your health history and goals. To compare forms and routines, read our guide to the best HRT options for perimenopause.

The 2025 review notes that there is little head-to-head data comparing these options. Pick by your symptoms, your health history and how much the flashes disrupt your days. Our guide to the best treatments for hot flashes covers the full list.

What can you do in the moment?

Treat the dread as the flash's opening seconds. In the Kronenberg study, what women felt tracked the flash itself, and the Menopause Society says each flash usually lasts 1 to 5 minutes. When you know the rush is a flash starting and that it will pass in minutes, it can feel less frightening.

The usual tricks do not cut flashes. The 2023 Menopause Society statement does not recommend paced breathing (Level I), or cooling techniques, avoiding triggers, exercise, yoga, mindfulness or relaxation (Level II), as ways to reduce hot flashes. They may feel calming, but the experts who reviewed the trials do not count them as hot flash treatments.

Skip supplements for this. The 2025 review found that evidence for soy, black cohosh, cannabis and probiotics is poor or inconsistent, and said none can be recommended.

CBT and hypnosis are the behavioral approaches with evidence. They used to mean repeated sessions with a specialist, but the 2025 review notes that self-guided versions now exist. The Penn researchers suggested CBT is worth considering for women whose flashes come with body-felt anxiety, because it lowered anxiety sensitivity in a meta-analysis. They noted that studies still need to test whether that lowers flashes.

Fewer hot flashes means fewer of those seconds of dread. Take the quiz to see whether bioidentical estrogen fits your plan, and our clinical team will look at your symptoms and health history.
