Effects on the Body

  • Adenosine, a neurotransmitter that promotes sleep and inhibits alertness, is the target of caffeine's activity. Caffeine boosts the levels of other neurotransmitters like dopamine and norepinephrine by blocking adenosine, which can result in an increase in alertness, energy, and mood.
  • Additionally, caffeine can impact the body's metabolism and thermogenesis, which is the process through which the body produces heat. It can also raise heart rate, blood pressure, and respiration. The heightened energy and focus that caffeine is known for may result from these side effects.
