The same moment, two realities
Her experience
Internal temperature spikes 5-10°F without warning. Skin feels like it's burning from the inside. Can't think, can't focus, needs it to stop now. This isn't preference — it's survival mode.
vs
His experience
It's 64°F. Again. You're wearing a sweater indoors in July. You were comfortable 10 minutes ago before the thermostat changed. You're starting to wonder if you'll ever be warm again.
Why this happens
Hot flashes are caused by the hypothalamus (your body's thermostat) getting false signals due to fluctuating estrogen. Her brain thinks she's overheating even when she's not. The response is real — flushing, sweating, heart racing — even if the room temperature hasn't changed. She's not being dramatic. Her thermoregulation is literally malfunctioning.

1
She controls the thermostat. No commentary.
When a hot flash hits, she needs immediate relief. The lag time between "I'm burning" and thermostat adjustment is already too long. No sighing. No "again?" Just let it happen.
2
He gets personal warming gear. Good stuff.
This isn't a punishment — it's equipment. Invest in quality layers, a heated blanket, maybe a space heater for your office. You're adapting to the environment.
His gear
Fleece, layers, heated blanket
Her gear
Personal fan, cooling towel
3
Zoned sleeping is allowed.
Separate blankets. A fan on her side. A heated mattress pad on his side. The bed can be two climates. This isn't a failure of intimacy — it's engineering for coexistence.
4
The baseline is cooler than he'd like.
It's easier to add warmth than remove it. When you're overheating from the inside, there's no sweater you can take off. Setting the default temp at 68°F (or lower) gives her room to breathe.
5
Acknowledge the absurdity together.
This situation is objectively ridiculous. You're living in a house with two climates and neither of you asked for this. Finding the humor — together — is a survival strategy.

The bigger point
The thermostat isn't really about the thermostat. It's about whether you're willing to be inconvenienced for her comfort — the same way she's been inconvenienced by her own body for months. Wearing a sweater indoors is the smallest thing you can do. Do it without complaint.
