Explanation:
Detailed explanation-1: -Brain scans conducted by UC Berkeley researchers showed one sleepless night leads to a shutdown of the medial prefrontal cortex-the part of the brain that helps manage anxiety.
Detailed explanation-2: -The thalamus is also important in sleep because it shuts off incoming signals from the senses, allowing us to rest.
Detailed explanation-3: -Stage 1 of the sleep cycle is the lightest phase of sleep and generally lasts about seven minutes. The sleeper is somewhat alert and can be woken up easily. During this stage, the heartbeat and breathing slow down while muscles begin to relax. The brain produces alpha and theta waves.
