What lifestyle choice can negatively impact sleep quality?

Caffeine intake, especially in the evening, is known to negatively impact sleep quality due to its stimulating effects on the central nervous system. Caffeine is a well-known stimulant that can increase alertness and reduce the ability to fall asleep. When consumed in the hours leading up to bedtime, caffeine can delay the onset of sleep, lower overall sleep duration, and reduce the amount of deep sleep a person experiences. This disruption can manifest in difficulties falling asleep and overall poor sleep quality, leaving one feeling less rested upon waking.

In contrast, regular exercise during the day, maintaining a consistent sleep schedule, and creating a calming bedtime routine each contribute positively to sleep health. Regular exercise can help improve sleep quality and reduce sleep latency, while a consistent sleep schedule helps regulate the body's internal clock, enhancing sleep efficiency. A calming bedtime routine promotes relaxation, making it easier to transition into sleep.
