Even if someone claims they can drink coffee in the evening and still sleep well, studies show that caffeine can still negatively affect deep sleep quality.

If you consume caffeine before noon, it can improve your sleep quality significantly.

People often don't realize the true impact of caffeine on their sleep, even if they feel immune to its effects.

Caffeine can disrupt sleep quality, so it's important to time caffeine intake appropriately to avoid negative effects on sleep.

Caffeine consumption can lead to a dependency cycle, where individuals feel the need to consume more to counteract poor sleep quality, and it is a sleep disruptor, with just one dose in the evening decreasing deep sleep by 20%.

Taking caffeine too early can mask sleepiness and lead to increased adenosine buildup, potentially causing a cycle of needing more caffeine throughout the day.

If you've been using caffeine regularly, you might be masking the quality of your sleep, leading to a false sense of being well-rested after caffeine consumption.

The more caffeine you consume, the more dependent you become, which can lead to poorer sleep quality.

Delaying caffeine intake by 90 to 120 minutes after waking can help offset afternoon crashes and improve nighttime sleep quality.
