JAKARTA - Coffee is a drink used as a sleep loss that is quite effective. Many people who do various daily activities have to drink coffee so they are not sleepy and stay focused.

However, there are also some people who will remain sleepy even though they have consumed coffee. This can happen because of several reasons, quoted from News Medical, on Thursday, February 6, 2025.

The caffeine content in coffee that helps a person not feel sleepy. However, regular caffeine consumption can lead to tolerance for its content and reduce the impact to prevent drowsiness.

This happens because the body is used to consuming certain amounts of caffeine. The body already has a high tolerance for caffeine, so it is immune and does not have an impact on removing drowsiness like in most people.

Drinking coffee with high sugar levels or consuming it more than once will cause fatigue. This happens because sugar is a simple carbohydrate, which has a high glycemic index.

Foods with a high glycemic index will increase the amino acid triptofan. These compounds will enter the brain and be converted into serotonin and melatonin, which is a hormone that affects drowsiness.

The cafe contained in coffee will increase the frequency of urinating. The amount of wasteful fluid when urinating can interfere with the balance of water levels and the body's normal function, causing dehydration.

When the body loses a lot of water, the blood will move slower so that oxygen circulates less. This causes the body to become tired and drowsiness to stay present, even though you have been drinking coffee.
