Two Sleep Processes Explained
- Sleep is regulated by homeostatic drive and circadian rhythm working together.
- Mismatch between these causes sleep problems like insomnia or excessive sleepiness.
Light's Impact on Circadian Rhythm
- Circadian rhythm is governed by light input affecting the brain's suprachiasmatic nucleus.
- Evening light exposure delays circadian timing, disrupting sleep onset and wake time.
Chemicals Driving Sleepiness
- Adenosine builds up during wakefulness to promote sleepiness; napping reduces levels, making falling asleep harder at night.
- Melatonin production is suppressed by light, delaying sleep onset.
