What this trial studies
This study examines the impact of sleep deprivation on the health of women across different phases of their menstrual cycle. It focuses on healthy young women who do not use hormonal contraceptives, aiming to fill the knowledge gap regarding how hormonal fluctuations influence responses to sleep deprivation. Participants will experience both sleep and wake conditions to assess the effects on brain health and metabolism. The study is particularly interested in the role of estrogen, a hormone that may protect against neurodegenerative conditions.
Why it matters
Potential benefit: If successful, this study could lead to improved health strategies for women working night shifts, potentially reducing risks associated with sleep deprivation.
How similar studies have gone: While studies have explored sleep deprivation and its effects on health, this specific focus on women’s hormonal cycles is relatively novel and has not been extensively tested.
