Sleep
Perimenopause Circadian Anchor
A perimenopause circadian anchor uses fixed wake times, morning light, and dim evenings to steady rhythm when cycles are irregular—limit long weekend lie-ins.
A perimenopause circadian anchor holds the same wake time daily—morning outdoor light within an hour of rising, dim evenings, and meal timing roughly consistent—to steady melatonin when cycles become irregular. Weekend lie-ins over ninety minutes can worsen Sunday night insomnia.
Training midday often beats very late sessions that delay temperature drop.
Common questions
-
Why does a fixed wake time matter if you sleep poorly?
Stable wake time builds sleep pressure for the next night. Sleeping in after rough nights often prolongs insomnia; nap briefly instead if needed.
