How Does Caffeine Work?
Caffeine is a central nervous system stimulant. This means that it speeds up the communication between your brain and your body. It does this by blocking adenosine, a neurotransmitter that makes you feel sleepy. When adenosine is blocked, you feel more alert and awake. Caffeine also increases the release of dopamine and norepinephrine, which further enhances alertness and reduces fatigue.
How Long Does Caffeine Last?
Before asking “why does coffee make me sleepy” consider how much caffeine you consume and how often. The effects of caffeine can last anywhere from 4-6 hours, but it also has a half-life of 5-6 hours. This means that if you consume 200 mg of caffeine (about two cups of coffee), after 5-6 hours, you will still have 100 mg of caffeine in your system. This can have a cumulative effect, leading to increased tolerance and potential dependence.
Why Does Coffee Make You Feel Tired?
So, if caffeine is a stimulant, why does coffee make you feel tired? There are a few reasons. Firstly, everyone’s sensitivity to caffeine varies. While some people can consume large amounts without feeling any negative effects, others may experience jitteriness or anxiety with even small doses. Secondly, caffeine intake can interfere with your sleep if consumed too close to bedtime. And finally, consuming too much caffeine in one sitting can lead to a crash in energy levels once the effects wear off.
Why Does it Mean that Coffee Blocks the Effects of Adenosine?
Caffeine blocks adenosine because it binds to the same adenosine receptors in the brain. This prevents adenosine from binding and causing drowsiness. However, once caffeine wears and is metabolized and cleared from the body, adenosine is able to bind again and cause feelings of sleepiness.
Why Does Coffee Make You Pee?
Caffeine in coffee is a diuretic, it can make you need to pee more often. So if you’re to drink coffee all day long, you may find yourself making more trips to the bathroom than you’d like. This can be especially frustrating if you’re trying to sleep or focus on work. So next time you’re reaching for a cup of Joe, just remember that it might make you tired AND make you have to pee. Drink coffee in moderation and enjoy your cup without having to worry about making too many trips to the bathroom.

Too much sugar in your coffee can also cause headaches, fatigue, and irritability. If you find that you’re experiencing these symptoms after adding sugar to your coffee, it’s best to cut back on the amount of sugar you use or switch to another sweetener.
