What Are Hot Flashes?
A hot flash is a sudden feeling of intense warmth that spreads across your body, especially your face, neck, and chest. It can last from 30 seconds to several minutes, often followed by sweating and sometimes chills. When they happen at night, they're called night sweats and can seriously disrupt your sleep.
Why Do They Happen During Menopause?
As oestrogen levels fluctuate and decline during perimenopause and menopause, your body's internal thermostat (the hypothalamus) becomes more sensitive. Even small changes in body temperature can trigger a hot flash, your body overreacts, dilating blood vessels and triggering sweating to cool down.
How Common Is This?
Hot flashes are the most commonly reported menopause symptom. Research shows that up to 80% of women experience them, and they can last anywhere from a few months to over a decade. Indian women often report them starting in their mid-40s, sometimes earlier.
What You Can Do. Lifestyle Strategies
Immediate relief:
- Keep a small hand fan or cooling towel handy
- Wear light, breathable cotton fabrics (especially at night)
- Keep your bedroom cool, 22°C or lower
- Sip cold water when you feel a flash coming on
Long-term management:
- Regular exercise: even 30 minutes of walking 5 days a week can reduce hot flash frequency
- Stress management: yoga, pranayama, and meditation help regulate the nervous system
- Dietary changes: reduce spicy food, caffeine, and alcohol. Increase soy-based foods (tofu, soy milk) which contain natural phytoestrogens
- Maintain a healthy weight: women with higher BMI tend to experience more severe hot flashes
- Deep breathing techniques: slow, rhythmic breathing (6 breaths per minute) can help calm the nervous system during a flash
What to track: Keep a simple diary of when hot flashes occur, what you were doing, and what you ate. Patterns often emerge that help you avoid triggers.
When to Seek Help
If hot flashes are disrupting your sleep, work, or daily life, that's reason enough to seek guidance. You don't have to "just deal with it." A doctor can help you explore options ranging from lifestyle modifications to medication if needed.
