Caffeine consumption in moderation is generally safe and may have health benefits, but excessive intake can lead to increased blood pressure.

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%.

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

Caffeine should be consumed with caution; it's best to limit intake to about three cups a day and avoid it 10 to 12 hours before bedtime, depending on individual sensitivity.

Expectations can significantly influence the effects of stimulants like caffeine, as shown in studies where students reported heightened effects based on their beliefs about the substance they consumed.

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

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

Caffeine acts as an adenosine antagonist, preventing sleepiness and enhancing alertness, but the timing and amount of caffeine consumed are crucial for optimizing sleep.

Caffeine is the only psychoactive stimulant that we readily give to our children, which raises concerns about its impact on their sleep.
