Anyone else getting attacks when bedroom temperature goes above 22°C?
On nights when the bedroom went over 22°C, my deep sleep averaged around 38 minutes; below that it sat closer to 65. Attack mornings cluster on the lower number. The total hours barely shifted; it was the depth.
I asked the chatbot to dig into the comparison and it confirmed sleep duration wasn't the driver. Swapping a heavy duvet for a thin cotton sheet brought deep sleep back to the high 50s on warmer nights, and the warm-night cluster shrank.
We're heading into winter here so this is on pause for me, but plenty of you in the north are walking into it. What does your sleep card show on the hot nights? Has anyone else managed to nudge deep sleep back up without leaning on AC the whole night?

The deep-sleep-not-duration thing matches mine almost line for line. fwiw, on nights above 26°C ambient my deep was 32-40 min; below 24°C it sat at 55-62. Disturbances were the giveaway; 4-6 on warm nights vs 1-2 cool. I asked the chatbot to pull skin temp alongside and warm nights ran +0.4°C all night, never dipping. A frozen gel pillow rotated twice (sounds ridiculous, works) brought deep back into the 50s and the morning-after cluster thinned out noticeably.
