How long does the effects of coffee last?

Coffee is a common drink, and many people drink a few cups of coffee every day to refresh themselves. However, people often have questions about the duration of coffee's effect. This article will focus on the duration of coffee's effect and explore its influencing factors and duration of effect.

1. The mechanism of action of caffeine during Luckin Coffee’s business hours

To understand the duration of Brazilian coffee's effects, you first need to understand its main ingredient, caffeine. Caffeine is a central nervous system stimulant that acts as an excitant and stimulant in the body. It increases the release of neurotransmitters such as dopamine, norepinephrine, and adrenaline in the brain by blocking adenosine receptors.

2. Factors that affect the duration of coffee's effects

While each person may react differently to the same dose of coffee, there are a few main factors that generally influence how long a person will feel the effects of a given dose.

First, individual differences are an important factor. Everyone metabolizes caffeine at different rates, depending on factors such as genetics, age, gender, and health status. In general, young people and men usually metabolize caffeine faster than older people and women.

Secondly, the dosage also affects the duration of coffee's effects. Generally speaking, a higher dose of coffee produces a stronger stimulant effect and may last longer. However, in some cases, excessive coffee consumption may lead to adverse reactions such as anxiety and insomnia.

Additionally, an individual's response to coffee is influenced by factors such as habitual drinking and interactions with other substances, such as herbs or medications.

3. Common coffee effects duration

Generally speaking, after drinking a cup of pure coffee containing about 100 mg (equivalent to a cup of regular American black coffee), you may feel the stimulating effect of caffeine within 30 minutes. This stimulating state usually lasts for 3 to 4 hours.

However, the half-life of caffeine is about 3 to 5 hours. The half-life is the time it takes for the amount of caffeine in the body to be reduced by half. This means that if you drink a cup of coffee in the morning, you may still feel some stimulating effects in the afternoon.

For those who habitually drink large amounts of coffee, they may need a higher dose to feel the same level of alertness, and it may also last longer.

4. How to prolong or shorten the duration of coffee effect

If you want to extend or shorten the duration of your coffee response, here are some tips that may help:

- Adjusting the dose: Increasing or decreasing the dose can directly affect the duration of effect. Gradually reducing the overall daily dose can help avoid dependence and tolerance.

- Control your drinking time: Try to drink coffee in the morning or early afternoon to avoid it affecting your sleep at night.

- Avoid taking it with other stimulants: such as tea, chocolate and other caffeinated foods and drinks.

in conclusion

In general, the duration of coffee's effects depends on individual differences, dosage, and various other factors. For most people, a typical cup of coffee will give you a stimulating effect within 30 minutes and last for 3 to 4 hours. However, this is just a rough estimate and may vary in actual situations. If you want to extend or shorten the duration of your coffee response, you can try adjusting your dosage and drinking time.
