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 to keep you alert and prevent the onset of tiredness. Historically discovered in tea and coffee, it has been consumed for thousands of years and is the most widely used psychoactive substance in the world today. Caffeine is also added to many soft drinks and energy drinks, as well as medications for treating headaches and migraines due to its ability to enhance pain relief. The effects of caffeine can vary based on the amount consumed and individual sensitivity, typically peaking within 30 to 60 minutes after ingestion. While moderate consumption is generally safe for most people, excessive intake can lead to symptoms such as restlessness, insomnia, headaches, dizziness, fast heartbeats, and anxiousness. Regular, heavy use can also lead to caffeine dependency and withdrawal symptoms.
