#sleep Not surprisingly, there are differences between how men and women sleep. From a purely biological standpoint, “Sex-based factors relate to underlying biologies including hormone production, sleep cycles, and circadian rhythm.”. Gender based difference could be more to do with societal norms and culture. “Studies have found differences in circadian rhythms for men and women. While most circadian rhythms are not exactly 24 hours long, women’s internal clocks are typically a few minutes shorter.
Women often have earlier circadian timing, meaning a tendency to both go to bed and wake up earlier.” We know for women in menopause hormone shifts cause temperature shifts (hot flashes) affecting sleep. As men age they also have hormonal shifts including reduced testosterone which has been shown to reduce sleep quality.
