How long does coffee last and its effects

Coffee is a widely loved drink that not only refreshes the mind but also has many other benefits. However, many people are not clear about the effects and duration of drinking coffee. This article will focus on the duration of coffee and explore the effects of drinking coffee on the body and brain.

1. How long does caffeine stay in the body?

First we need to understand how long caffeine stays in the body. Typically, a regular cup of coffee (about 240 ml) contains about 95 mg to 200 mg of caffeine. These values ​​may vary depending on individual differences.

It takes about 15 to 30 minutes from ingestion to start feeling the effects, and the peak concentration gradually increases until about 60 minutes later. After that, the concentration gradually decreases over the next few hours.

Generally speaking, the longest time that caffeine stays in the blood is 4-6 hours, and the half-life is about 3-5 hours. This means that if you have a cup of coffee in the afternoon, you may still feel the effects of caffeine in the evening.

2. Effects of coffee on the body

Drinking coffee can bring many physical benefits. First, caffeine can stimulate the central nervous system, improving alertness and concentration. This is why many people drink a cup of coffee first thing in the morning.

Additionally, studies have shown that moderate caffeine intake can also increase metabolic rate and promote fat oxidation, which means that drinking coffee can help reduce fat accumulation and may help with weight management.

Another benefit is its ability to improve athletic performance. Studies have found that, in moderate doses, consuming moderate amounts of caffeine can improve endurance and strength, and reduce perceived exertion.

3. Effects of coffee on brain function

In addition to its positive effects on the body, coffee also has some effects on brain function. First, caffeine can improve attention and concentration. Studies have shown that moderate caffeine intake can improve cognitive performance and reduce distraction.

Caffeine can also improve memory and learning abilities. One study found that after consuming moderate amounts of caffeine, participants performed better on memory tests and learned new information faster.

However, it should be noted that excessive intake of caffeine may cause side effects such as anxiety, restlessness and insomnia. Everyone has different tolerance to caffeine, so please control your intake according to your physical condition.

4. Prolonging the effect: How to make the effect last longer

If you want to make the effects of a cup of coffee last longer, the following tips may help:

- Choose coffee beans or powder with a higher concentration and better quality.

- Try to avoid drinking coffee on an empty stomach before meals, as an empty stomach will accelerate the absorption of caffeine.

- Try to avoid drinking coffee in the evening to avoid affecting your sleep quality.

- Avoid excessive caffeine intake to avoid side effects.

in conclusion

In summary, drinking coffee can bring many benefits, and the duration of its effects is related to individual differences. Understanding the effects of coffee on the body and brain can help us better utilize its benefits. However, remember to consume it in moderation and reasonably control the intake according to your own physical condition to avoid unnecessary side effects.
