Caffeine can make you feel more alert and focused, but it can also cause feelings of fatigue if you consume too much. Caffeine affects everyone differently, so it’s important to keep track of how much you’re consuming and how it’s making you feel. Too much caffeine can cause symptoms like jitteriness, difficulty sleeping, and fatigue. Caffeine can also interfere with your body’s natural sleep cycles, making it harder to get a good night’s rest. To avoid these effects, it’s best to limit your caffeine intake and be aware of how it affects you.

Why does caffeine make me sleepy?

Caffeine is a stimulant and can provide an energy boost, but it can also have the opposite effect and make you feel sleepy. This is because caffeine can interfere with your body’s natural sleep cycle. When you consume caffeine, your body releases adrenaline, which can cause alertness, but it also disrupts the production of adenosine, a hormone that helps you feel sleepy. Without enough adenosine, you can become overly alert and have difficulty falling asleep. Additionally, caffeine has a half-life of five to six hours, meaning that it can stay in your system for a long time and continue to affect your sleep.
