Those of us who drink coffee daily often wonder what the effect of coffee is on the body and until what time it is recommended to consume it, if it contains caffeine, of course. We all know the effects of caffeine on the body, and although used correctly, it can help us increase energy, when training, studying, or waking up.
It is important to know the right time to drink coffee or not and whether that cup will alter our nightly rest or help us get through everything you have to do during the day. That is why we should know how long the effect of coffee lasts in our body.
Caffeine and its effects on the body
Caffeine is a bitter substance that is found naturally in more than 60 plants, including:
- Coffee beans
- Tea leaves
- Cola nuts, which are used for the flavoring of cola drinks
- Cocoa pods, which are used to make chocolate products
Caffeine has many effects on your body's metabolism. The most relevant are:
- Coffee stimulates the central nervous system, which can make us feel more awake.
- It is a diuretic, which causes the body to get rid of extra water and salt by urinating more.
- It can interfere with the absorption of calcium in the body.
- It increases blood pressure.
How long the effect of caffeine lasts
It takes between 15 and 20 minutes for the body to feel caffeine and its effects. It starts absorbing caffeine as soon as you start drinking coffee, as caffeine can pass very easily through epithelial tissue, such as the lining of the mouth, throat, and stomach. And its peak is noticeable at 30-60 minutes. From there, the amount of caffeine in the blood decreases until it finally disappears, in a time that can range from 2-3 hours up to 6 hours.
Thus, the question of how long the effects of coffee last cannot be answered exactly. We can, however, speak of averages, and these place the duration of the effect of caffeine from a cup of espresso between 2 and 3 hours.
