sleep science

Sleep science is the peer-reviewed study of how the human body
and brain behave during sleep — covering sleep stages, circadian
rhythms, sleep disorders, and the biological mechanisms that make
quality sleep essential for health, memory, and performance. Every
article in this category is written using primary research from
institutions including NASA, Harvard Medical School, and the American
Academy of Sleep Medicine (AASM), and reviewed by Dr. Sarah Mitchell,
a Certified Clinical Sleep Health Specialist (CCSH). Whether you want
to understand why 90-minute sleep cycles matter, how REM sleep
consolidates memory, why sleep debt accumulates faster than it
recovers, or what the circadian dip at 1–3 PM means for your nap
schedule — this is your evidence-based resource for understanding
the science behind better sleep.
