What is caffeine really doing in our bodies?
Caffeine is a stimulant found in many foods and beverages, including coffee, tea, chocolate, and energy drinks. It works by blocking the action of adenosine, a chemical that makes us feel tired. When adenosine binds to its receptors in the brain, it causes us to relax and fall asleep. Caffeine blocks this binding process, sending a signal to the brain that we're alert and awake.Caffeine's impact on our bodies can also lead to negative side effects such as jitters, anxiety, and insomnia. Additionally, high levels of caffeine consumption have been linked to increased heart rate, blood pressure, and risk of stroke and other cardiovascular problems.
