During this lightest stage of NREM sleep, a person transitions from being awake to being asleep.
This stage of the process is characterized by a slowing of the heartbeat, breathing, and eye movements.
A person typically spends only 5% of their total sleep time in stage 1, which lasts for a few minutes.
During this time, a person's heart rate slows and their muscles continue to relax. Sleep spindles, which are brief electrical activity spikes, happen as a person's brain waves slow down. Studies show that sleep spindles help with memory consolidation.

In stage 2, sleepers spend about 45% of their total waking hours. This stage typically lasts longer with each cycle, with the first cycle taking around 25 minutes.
