Coffee: Around 8 out of 10 French people drink it regularly. When consumed in moderation, coffee has many health benefits: improving memory, concentration, and mood. But what are its effects on sleep? In this article, Bdreams tells you more!

1. How does coffee affect our body?

Neurons in the human brain produce adenosine throughout the day, which primarily promotes sleep and allows the body to rest and replenish its energy reserves. When you drink coffee, caffeine blocks and acts on adenosine, causing an increase in heart rate and body temperature, helping to keep the body awake.

2. How much coffee can you consume without affecting your sleep?

Caffeine begins to work on average 15 to 30 minutes after ingestion, and its effect lasts from 3 to 6 hours depending on the individual. A morning cup therefore has no impact on the night. The afternoon cup can be more disruptive. But this depends on each individual, particularly their consumption. The effects will be weaker in people who consume it regularly.

Fun Fact: The world record for most cups of coffee in one day is 84 cups! The lethal dose is 100 cups per day.

3. Coffee: Addiction or Just a Habit?

Coffee is also known for its addiction. A cup of coffee at breakfast, an espresso after a meal, the famous " coffee break " at work—there are so many opportunities to drink coffee throughout the day. But caffeine, as we know, stimulates and energizes, and it's sometimes difficult to do without it during the day and evening. This addiction even leads to a vicious circle, as we consume coffee to stay fit and perform, often to compensate for a lack of sleep... which can itself be caused by caffeine. Coffee therefore becomes a disruptive element of restful sleep.
