What happens to your body when you drink your morning coffee?

A study conducted in 2019 on 80 people between the ages of 18 and 22 found that the effects of coffee on your body begin even before you take your first sip. Another study showed that people performed better on tests of analytical reasoning after inhaling the aroma of coffee, but it also showed that there was a "placebo effect" due to the brain's a priori knowledge of coffee's energizing effects. In such a case, Dr. Mike Nilsson argues, "the use of any supplement may have a placebo effect."

However, according to a report in the UK's Guardian newspaper, the really powerful effects of coffee begin 10 minutes after consumption, with caffeine levels in the blood peaking after about 45 minutes.

How does coffee wake you up?

Caffeine is a central nervous system stimulant that can make you more alert and focused. It is associated with adenosine receptors in the body. Adenosine is a naturally occurring organic compound in the body that may help regulate heart rate, blood flow, and sleep-wake cycles. When adenosine binds to these receptors, it triggers a physiological response that leads to decreased activity and often promotes sleepiness and sleep.

The caffeine in coffee, on the other hand, tricks your nerve cells and binds to them instead, thus preventing adenosine from working, which in turn increases the body's alertness, and also allows brain-stimulating neurotransmitters, such as dopamine, to work, which stimulates the body's physical and mental state.

Can coffee prolong life?

In recent years, all studies have confirmed that drinking coffee can bring many health benefits, and a scientific study published on the platform of the European Society of Cardiology (ESC) has shown that drinking more coffee can reduce the risk of death.

This was not a small study, but a large one with about 20,000 participants. The researchers followed the health of the participants for a full 10 years, while their average age was 37.7 years. The study found that participants who drank "at least four cups of coffee a day" had a 64 percent lower risk of death compared to non-coffee drinkers. In the study, the benefits were most pronounced in older adults; participants over 45 years old had a 30 percent lower risk of death for every additional two cups of coffee they drank per day.
