= Coffee’s energy-boosting effect (1)
The caffeine in coffee elevates your energy levels.
Caffeine increases alertness and reduces fatigue by increasing dopamine levels and blocking adenosine.
Dopamine is the chemical messenger responsible for the jittery effect of coffee, as it increases your heart rate. It also affects your brain’s reward system, which adds to coffee’s addictive properties.
= Tea’s effect on energy (2)
Though tea is lower in caffeine, it’s rich in L-theanine, a powerful antioxidant that also stimulates your brain. (3)
Unlike caffeine, L-theanine may provide anti-stress effects by increasing your brain’s alpha waves, which help you calm down and relax.
Both coffee and tea increase your energy levels. However, coffee gives you an instant kick, while tea offers a smooth boost.
