What dietary recommendation is suggested to improve sleep quality?

Avoiding caffeine 4-6 hours before bed is recommended to improve sleep quality because caffeine is a stimulant that can interfere with the body's natural ability to fall asleep and stay asleep. When consumed, caffeine can increase alertness and delay the onset of sleep, making it harder for individuals to wind down at night. By refraining from caffeine in the hours leading up to bedtime, individuals give their bodies the opportunity to relax, promoting better sleep onset and overall sleep quality. This practice aligns with the body's circadian rhythms and can help ensure a more restful night’s sleep.
