You often hear that coffee can keep you awake at night. Many people intentionally drink coffee so that they can stay up late until midnight, even into the morning to do homework or just to watch football in the early hours of the morning. Yes, the effect of coffee in keeping people awake is believed by many people. For coffee fans and those who like to stay up late, perhaps coffee is very useful. However, for those of you who are not, of course coffee can disturb your sleep. Remember, staying up late too often is also not good for health.

How does coffee keep you awake?

You must know that coffee contains caffeine. Not only coffee contains caffeine, but also in tea, chocolate, and some soft drinks. This caffeine content is what keeps you awake even in the middle of the night. Caffeine is a stimulant drug that acts as an adenosine receptor antagonist. Adenosine is a compound in the body that makes you sleepy. Caffeine blocks the action of adenosine receptors in the body, so it prevents you from feeling drowsy.

Caffeine can start affecting your body as soon as it enters your body. Caffeine enters the bloodstream through the stomach and small intestine and can peak in the bloodstream about 30-60 minutes or even earlier, after consumption. Half of the caffeine entering the body can last for 3-5 hours, the other half can stay in the body for a long time, about 8-14 hours.

Caffeine can interfere with your sleep, making it difficult for you to fall asleep and thus impair your sleep. Caffeine can also make it difficult to get a good night's sleep or stay asleep.


What affects the effects of caffeine on the body?

The effects of caffeine on sleep can vary between individuals. This can be caused by various factors, such as:

Genetic factors: Heredity causes the metabolism of caffeine in the body to vary between individuals. However, research on this topic is still limited.

Age factor: Some studies suggest that the older a person is, the more sensitive a person is to the effects of caffeine.

Caffeine consumption habits: Research shows that caffeine has less of an effect on regular coffee drinkers than in occasional coffee drinkers.

Time consuming: Consuming caffeine near bedtime is likely to have a greater impact on sleep disturbances.

However, recent research shows that the effects of caffeine can occur even if you consume it in the afternoon or evening. Research published in the Journal of Clinical Sleep Medicine shows that drinking coffee 6 hours before bed can reduce total sleep time by up to 1 hour.


What is the maximum coffee consumption limit?

The caffeine content in coffee varies among other coffee products. The caffeine content in coffee depends on many factors, such as the type of beans used and how the coffee is served.

Moderate coffee consumption, i.e. three cups of coffee (250 mg of caffeine) per day, is unlikely to pose a health hazard. However, consuming 6 or more cups of coffee per day can cause excessive caffeine in the body and can be harmful to health. Excessive levels of caffeine in the body can increase heart rate and breathing rate.

For children, on the other hand, moderate coffee drinking can already have a negative impact on nutrition, fearing that coffee could replace nutritious drinks for children, such as milk. Coffee can also cause children to eat less because the caffeine in coffee can act as an appetite suppressant. We recommend that you avoid giving coffee to children.


Reporting from Medical News Today, Prof. Drake, an investigator at the Henry Ford Center for Sleep Disorders and Research, says you should also avoid caffeine after 5 p.m. If you want a good night's sleep.
