Question

What effect does caffeine have on the sleep cycle

Answer 1

Caffeine elevates heartrate and is a diuretic, during the sleep cycle caffeine cause you to need to pee more often, and an elevated heart rate would cause more restless sleep 

Answer 2

Because caffeine is a stimulant, most people use it after waking up in the morning or to remain alert during the day. While it is important to note that caffeine cannot replace sleep, it can temporarily make us feel more alert by blocking sleep-inducing chemicals in the brain and increasing adrenaline production.
