Coffee is one of the most consumed beverages in the world, and many choose it to start their day. But does it give us energy, or is it just a temporary effect?
Does coffee give you energy, or is it just a temporary sensation? This question has sparked debate among experts and consumers, especially since millions of people around the world start their day with a cup of this beverage.
The short answer is yes: coffee can give you energy, and this is due to its main active ingredient: caffeine. This substance is a natural stimulant of the central nervous system, and its mechanism of action is well documented.
When you consume caffeine, it blocks the action of a neurotransmitter called adenosine, which is responsible for inducing sleep and fatigue. Blocking it has the opposite effect: it increases neuronal activity and releases substances like dopamine and norepinephrine, which improve alertness, mental focus, and feelings of energy.
In addition to these cognitive benefits, caffeine can also have a physical impact. It stimulates the release of adrenaline, which can boost performance during athletic activities and improve short-term endurance.
The effects of coffee are usually felt 15 to 45 minutes after consumption and can last 3 to 5 hours, although this varies depending on individual tolerance and metabolism.
However, not everything is positive. Some people are more sensitive to caffeine and may experience side effects such as nervousness, rapid heart rate, insomnia, or gastrointestinal discomfort. Therefore, specialists recommend moderating your intake, avoiding more than 400 mg of caffeine per day, which is equivalent to approximately 3 or 4 cups of coffee.
In conclusion, coffee can indeed give you a real energy boost, as long as it’s consumed in moderation. This isn’t just a perception: science supports its effectiveness as a natural stimulant, ideal for staying alert at key times of the day.
