What is the effect of caffeine on my body?
When ingesting caffeine from soft drinks, energy drinks or other drinks, the drinker gets a stimulating effect. This invigorating effect is accompanied by a higher heart rate and breathing.
Research has shown that 3-6 milligrams (mg) of caffeine per kilogram (kg) can improve performance during intense exercise. Coffee intake can also improve concentration at work.
When caffeine is taken regularly, the body quickly gets used to it and its effect diminishes. If you drink constantly during the week and not at the weekend, this will possibly result in headaches, fatigue and trembling hands.
Caffeine doesn't have to be bad at all! Only use it in moderation! It is advised not to consume more than 400mg of caffeine per day.
