We always hear about hot flashes, but nobody warns you about the “Cold Flash.”
One minute you’re peeling off layers, and the next, you’re shivering and hunting for a blanket. If you’ve felt like your internal thermostat is broken lately, you aren’t alone—and you’re not “losing it.” This is something many women experience during perimenopause, even if it’s not talked about as often.
What’s actually happening?
It all comes down to a tiny part of your brain called the hypothalamus. Think of it as your body’s command centre for temperature, working to keep you in a comfortable range.
During perimenopause, shifts in estrogen can make the hypothalamus more sensitive. Instead of regulating temperature smoothly, your body can swing more quickly between feeling too warm and too cold. That’s why you might experience a hot flash followed by a sudden chill— it’s
just your body working to rebalance.
3 Simple Ways to Manage the Chills
As a coach and a woman moving through perimenopause, I see this thermostat shift often. Here are a few gentle ways to support your body:
- Wear Moisture-Wicking Layers: If your skin stays damp after a hot flash, the chill can feel much stronger. Breathable, natural fabrics can help you adjust more comfortably.
- Warm Herbal Support: Keep a warm ginger or goji berry tea nearby. It helps stabilize your core temperature more gently than a sudden blast of heat.
- Check Your Stress: Your nervous system and hormones are closely linked. When a chill hits, take a few deep belly breaths. It tells your brain you’re safe and helps settle the temperature swing.
Nutrient Support for Your “Internal Thermostat”
What we eat plays a role in how our body communicates and adapts. To help steady those temperature shifts, consider:
- Magnesium-Rich Foods: Pumpkin seeds, spinach, and almonds can support nervous system balance and help your body stay more at ease.
- Phytoestrogens: Flaxseeds and non-GMO soy can gently mimic estrogen in the body, which may help take the “edge” off those dramatic spikes and drops.
- Healthy Fats: Avocado and walnuts support the production of all hormones, including the ones that tell your brain you’re at a safe temperature.
I always say—your body isn’t trying to make your life difficult; it’s simply communicating in a new way. When we learn to listen, we can begin to support it with more ease.
Simply Salt & Soul
The Salt (The Science): During perimenopause, shifts in estrogen can influence how the hypothalamus regulates body temperature. This can narrow your body’s comfort zone, making you more sensitive to even small changes. As your body adapts, you may move more quickly between feeling warm and cold. Supporting your system with steady meals, hydration, and a calm nervous system can help promote more stable regulation.
The Soul (The Wellness): There’s a moment during a cold flash where it can feel unsettling—like your body is no longer predictable. But this isn’t dysfunction, it’s transition. Instead of resisting it, meet it with warmth: wrap yourself in something soft, sip something warm, slow your breath. These small acts remind your body it’s supported, even in the shift.
