Have you ever wondered what really happens in our body after the first sip of morning coffee? How does caffeine affect our body and well-being? Is this refreshing drink really that effective for increased alertness?
The first morning coffee has a special meaning for many people and is an indispensable ritual to start the day. The smell of freshly brewed coffee and its taste wake us up and fill us with energy. However, its effect on the body does not last only a few moments after ingestion.
Caffeine, which is the main component of coffee, has longer-term effects on our body that take place in the next 6 hours after drinking. During this time, various physiological processes take place that affect our well-being and functioning.
Let's look at the timeline!
0 – 10 minutes
When we drink our first coffee in the morning, caffeine begins to be quickly absorbed and spread throughout the body. During this time, we notice an increase in blood pressure and heart rate. Caffeine also prevents the absorption of dopamine in the brain, which makes us feel more positive and happy. This temporary lift in mood is often what makes us more alert and ready for a new day.
10 – 20 minutes
Caffeine binds to adenosine receptors in the brain, which are responsible for the feeling of fatigue. By doing so, it prevents adenosine from binding to these receptors and consequently reduces the feeling of fatigue. This effect contributes to a feeling of alertness and focus.

The adrenal glands start to work and secrete more adrenaline and other hormones that contribute to the increased feeling of energy. At the same time, caffeine dilates the pupils, which improves our vision.
40 minutes
The body begins to produce more serotonin, a neurotransmitter that plays a key role in mood regulation. This can improve the functioning of neurons in the spinal cord, leading to better coordination and muscle strength.
4 hours
Metabolism is accelerated, which means that energy is used faster. During this time, the breakdown of stored fat in the body also begins, which can help with weight loss.

6 hours
After six hours, most are caffeine already eliminated from the body. Because of this, we may feel an increased need to urinate.
It is important to maintain moderation when consuming coffee, as excessive caffeine can cause side effects such as restlessness, insomnia and increased heart rate. The key is to listen to your body and enjoy coffee as a pleasant experience that fills us with fresh energy for a new day.
