The Effect of Sleep Extension on Metabolic and Androgen Parameters of Healthy Women with Habitual Short Sleep Duration: Pilot Study
TLDR Increasing sleep by 41 minutes daily for a month showed no significant changes in metabolism or hormone levels in healthy women.
This pilot study investigated the effects of sleep extension on metabolic and androgen parameters in healthy pre-menopausal women with habitual short sleep duration (≤ 6 hours). Ten participants were instructed to increase their sleep by one hour daily for one month, with seven completing the intervention and increasing their sleep by an average of 40.7 ± 14 minutes. Despite this increase, no significant changes were observed in insulin sensitivity, androgens, or leptin levels. The study concludes that further research with larger sample sizes and more controlled designs is necessary to understand the impact of sleep extension on these parameters.
