How long does the effect of coffee last?

Coffee is a must-have drink for many people in the morning. It can refresh the mind and increase attention and concentration. However, the effect of coffee is not infinite. This article will explore the effect of coffee from different perspectives and explain the reasons.

1. How long does caffeine stay in the body?

First, we need to understand how long caffeine stays in the body. Generally speaking, after consuming a cup of coffee, about 80% to 90% of the caffeine will be absorbed into the blood circulation system. Then, it will be gradually broken down and metabolized in the body.

According to research, the highest concentration is reached within 30 to 60 minutes after ingestion and lasts for several hours. Usually, the residual caffeine in the body can be completely eliminated 4-6 hours after ingestion.

2. The effects of coffee last longer for addicts

However, not everyone experiences the same duration of effects after drinking a small or moderate amount of caffeine (e.g. 50-200 mg) such as a cup or two of afternoon tea. In fact, there is a lot of individual variation.

Some people may be more sensitive to caffeine and feel awake and alert longer after consuming it. Conversely, others may have a lesser reaction to caffeine and its effects may not last as long.

3. Caffeine Metabolism Rate

The differences between individuals are mainly due to different rates of caffeine metabolism. One study found that in some people, there is a gene variant that can affect the activity level of a specific enzyme in the liver (CYP1A2).

This gene variant causes these people to metabolize caffeine faster than other people, so they typically experience a shorter but more intense stimulant effect from the same dose of coffee, but return to normal quickly.

4. Individual habits and tolerance

In addition, the duration of coffee's effects may also be affected by the individual's habituation and tolerance to long-term coffee drinking. Long-term coffee drinkers may need larger doses to achieve the same effect, and their response to caffeine may also be diminished.

This is because the body gradually adapts to caffeine and adjusts its metabolism and clearance rate. As a result, they may take longer to feel the stimulating effects, and the effects may not last as long.

5. Other influencing factors

Finally, there are other factors that can affect how long coffee stays in the body and how long it lasts. For example, a person’s weight, age, health, and what foods they consume at the same time can all have an impact on how well coffee tastes.

In summary, in most cases, the stimulating effects of one or two cups of normal strength coffee (about 100-200 mg) can usually last for about 4-6 hours. However, keep in mind that everyone has different levels of sensitivity and tolerance to caffeine.

in conclusion

This article explores the question of how long coffee's effects last and what factors influence them. Caffeine stays in the body for about 4-6 hours, but this varies greatly from person to person.

Genetics, personal habits and tolerance all play a role in how long coffee lasts. Other factors such as weight, age and health may also modify the effects of coffee.

Finally, remember to drink coffee in moderation and adjust your intake to your needs to fully enjoy its stimulating effects.
