Why I still feel tired after drinking coffee?

For a lot of people, their day usually starts with a cup of coffee. Whether it is steaming hot or iced, just one sip will give them full energy and increase alertness through the following hours of work. However, sometimes drinking coffee can have the opposite effect. If you have ever experienced that and are wondering why coffee makes you tired, this essay will answer for you.

Coffee increase dehydration

Coffee is a diuretic, which means it makes you need to urinate more than usual and may lead to dehydration in some people. When you are in dehydration, you will have a faster heartbeat rate and higher blood pressure. That way, your body is actually doing extra work and you will feel very tired or sluggish very soon. What’s worse, you may probably reach for more coffee to stay energetic, just to get more dehydrated and tired in the end. The only solution is to drink enough water to keep hydrated, around 2.5 to 3.5 liters of water per day.

The adenosine makes you sleepy after the caffeine wears off

Adenosine is a neurotransmitter that causes fatigue. The caffeine just blocks adenosine receptors from receiving adenosine, but it doesn’t stop your body from producing the matter. Therefore, after the effect of the caffeine wears off, you will feel sleepy due to the buildup of adenosine. Some avid coffee drinkers don’t suffer from this experience, they actually get boosted to the normal energy levels. But for most of us, it’s recommended to drink no more than 400 mg of caffeine per day, in other words, around 4 cups of coffee.

Sugary coffee can lead to a sugar crash

Sugar or sugary foods are consumed by your body more quickly than coffee, and it leaves no energy after it is used up. You will experience this energy slump and feel tired and sluggish afterward when you drink coffee-flavored drinks or coffee with syrups, chocolate, whip cream, etc. Of course, coffee may also cause hypoglycemia, and caffeine can disrupt glucose levels. When the level gets too low, you may experience fatigue and sleepiness. But there’s no need to worry about that as long as we are not diagnosed hypoglycemia. Just remember, avoid sugary food as you can, and add a delicious natural cream if you need a sweetener.
