Heat activates the parasympathetic nervous system through thermoreceptors in the skin. It signals to the body that it is safe, warm, and not under threat.

For women in perimenopause, this can feel counterintuitive given hot flushes. But the kind of warmth we are talking about is gentle and chosen, not the internal heat of a flush.

Hot flushes are the body attempting to cool down. Using a warm heat pack on your hands or feet, rather than your core, can actually help regulate this response for some women.

Experiment gently. If warmth makes flushes worse for you, the breathwork or grounding practices will serve you better.

There is significant research on the psychological and physiological effects of holding a warm cup. Holding warmth activates similar pathways to feeling socially connected and safe.

If you have a warm drink available, make one now. Hold it in both hands for a moment before you drink. Notice what that feels like.

If you have access to a bath or warm shower, try this: spend the first two minutes simply feeling the warmth on your skin without doing anything else.

No productivity. No planning. No scrolling. Just the sensation of warmth and water.

Place a heat pack, warm towel, or hot water bottle on your lower back, belly, or feet. These areas have high concentrations of thermoreceptors and respond quickly.

Rest with it for five to ten minutes. Let the warmth be the whole thing.

The most powerful use of heat is as a transition ritual. Use it deliberately to mark the end of the working day. A warm drink. A brief shower. A heat pack while sitting quietly.

The nervous system learns from repetition. Over time, the ritual itself begins to signal the shift, even before the warmth arrives.
