The main reason coffee wakes us up is the caffeine contained in it. Caffeine stimulates the central nervous system, causing various physiological reactions.source: pixabay
First, caffeine blocks adenosine receptors in the brain by acting as a competitive inhibitor of adenosine. Adenosine is a brain signaling molecule related to sleep and rest, and when caffeine blocks it, fatigue is reduced and it helps you stay awake.

Second, caffeine promotes the secretion of epinephrine and norepinephrine in the adrenal glands. This increases heart rate, raises blood pressure, and encourages the body's energy consumption to breathe energy into the body.출처: pixabay
In addition, caffeine accelerates the process of removing toxic substances by promoting the activation of enzymes in the liver. This improves liver function and helps prevent harmful substances from accumulating in the body.Lastly, caffeine stimulates the central nervous system, improving cognitive performance and memory, and speeding up the body's response. This temporarily helps you think faster and focus clearly.
In conclusion, the reason why I wake up when I drink coffee is mainly because of the action of caffeine.
Caffeine stimulates the central nervous system, reducing fatigue and inspiring energy. However, excessive caffeine consumption can cause side effects such as sleep disorders and anxiety, so it's important to maintain an appropriate amount. Therefore, it's better to keep an appropriate intake and take care of your health when drinking coffee.
