## What Is Caffeine and How Do Coffee Calculators Work?
### Caffeine Definition
Caffeine is a natural stimulant found in coffee beans, tea leaves, cacao pods, and kola nuts. It works by blocking adenosine receptors in the brain, which helps you feel more alert and awake.
### Coffee Calculator Functions
Coffee and caffeine calculators help you:
- Calculate optimal caffeine intake based on your weight and sensitivity
- Determine the best time to consume caffeine for maximum benefits
- Track your daily caffeine consumption across different beverages
- Plan your coffee consumption to avoid sleep disruption
### How Caffeine Affects Your Body
- **Stimulates the central nervous system**: Increases alertness and reduces fatigue
- **Improves cognitive performance**: Enhances focus, memory, and reaction time
- **Boosts physical performance**: Increases endurance and reduces perceived exertion
- **Affects sleep**: Can disrupt sleep if consumed too late in the day
- **Increases heart rate and blood pressure**: Temporary cardiovascular effects
### Caffeine Half-Life
Caffeine has a half-life of approximately 5-6 hours, meaning:
- After 5-6 hours: 50% of caffeine remains in your system
