Sleep > Circadian Rhythms
Circadian Rhythms
Internal clocks guide when you sleep, when you wake up, and when you get hungry.
BrainFacts/SfN
What on Earth is Sleep?
Sleep is a reversable state of low mobility and reduced responsiveness to external stimuli.
BrainFacts/SfN
Circadian Rhythm: The Clock that Keeps on Ticking
Our body’s natural sleep-wake rhythm, or circadian rhythm, helps us stay healthy and function throughout our daily lives.
BrainFacts/SfN
Light and the Brain
Light influences the brain more than you can imagine.
BrainFacts/SfN
Night Owl Chronotypes in a Morning Lark World
The modern world has changed when we sleep — but our work and school schedules have failed to keep pace.
BrainFacts/SfN
Retinal Ganglion Cells
Retinal ganglion cells are the conduit between the eyes and the brain.
BrainFacts/SfN
Are People Really "Morning Larks" or "Night Owls"?
Our sleep schedules aren’t simply personal preferences — they’re innate, biological predispositions that affect our physical and mental health.
BrainFacts/SfN
Why Do Adolescents Go to Sleep Late?
Teens’ nocturnal lifestyles are more than a personal preference — dramatic hormonal changes during puberty alter the brain circuits that regulate sleep.
BrainFacts/SfN
Resetting the Brain's Clock
Jet lag, irregular sleep schedules, and exposure to artificial light throw our internal clocks out of whack. When that happens, our health suffers.
BrainFacts/SfN
Syncing the Body's Clock
Sun-seeking brain cells keep the sleep cycle in balance.
