Fatigue
While caffeine can cause insomnia, it can also end up giving you a strong case of fatigue.
This can seem like it goes against the fact that most caffeinated beverages (tea and coffee included) end up giving you a boost of energy, and that is why most people end up choosing them.
Yet, they can also end up giving you the opposite effect, as when caffeine leaves your system, you can end up having rebound fatigue.
Studies have been made to see how caffeine affects people and what the side effects are immediately after, and one such study has shown that rebound fatigue is more than just a theory.
A review of 41 studies has shown that people who participated reported that after they drank energy drinks that contained caffeine, the next day they reported being way more tired than usual.
Consuming caffeine can lead you to be more alert and in a better mood. To ensure that you are not suffering from rebound caffeine, you need to only consume it in moderate doses.
Do not go for several energy drinks and keep your coffee intake in the recommended amounts, while ensuring that if you drink different sources of caffeine, you do not go above the FDA-recommended 400 mg daily!
