[00:00:00]A 2024 study brought healthy women into hospital and tested two things separately. Fragmented sleep and low estrogen. Fragmented sleep alone caused more attention lapses and slower reaction times.

[00:00:15]Even when total sleep time stayed the same.

[00:00:18]Low estrogen worsened attention. When both were present, the effects added up.

[00:00:25]A double whammy as they say.

[00:00:28]That's why broken sleep during perimenopause hits your brain differently than broken sleep at other times in your life.
