Caffeine is a natural stimulant most commonly found in tea, coffee, and cacao plants. It works by stimulating the brain and central nervous system, helping you stay alert and prevent the onset of tiredness.

Normally, adenosine levels build up over the day, making you increasingly more tired and causing you to want to go to sleep. Caffeine helps you stay awake by connecting to adenosine receptors in the brain without activating them. This blocks the effects of adenosine, leading to reduced tiredness.

  • Consuming small amounts of caffeine about an hour before exercise is likely to improve exercise performance.

  • Caffeine may boost metabolism and promote fat loss, but these effects are likely to remain small over the long term.

  • Caffeinated beverages like coffee and tea may reduce the risk of heart disease and type 2 diabetes, although this may depend on the individual.

  • Caffeine may improve mood, decrease the likelihood of depression, stimulate brain function, and protect against Alzheimer’s and Parkinson’s disease.
