WHAT IS CAFFEINE?
Caffeine is a naturally occurring stimulant that is found in various foods and beverages, including coffee, tea, chocolate, and some soft drinks. It works by blocking the action of adenosine, a neurotransmitter that is responsible for promoting relaxation and sleep, which results in increased alertness and decreased fatigue.
Caffeine is often consumed for its stimulating effects, as it can improve mental alertness, increase energy levels, and enhance physical performance. It has also been studied for its potential benefits in improving cognitive function, memory, and mood.
However, excessive caffeine consumption can lead to side effects such as restlessness, anxiety, insomnia, and increased heart rate. It can also lead to withdrawal symptoms when consumption is abruptly stopped, including headache, fatigue, and irritability.
Individuals who are sensitive to caffeine or who have certain medical conditions, such as anxiety disorders or cardiovascular disease, may need to limit or avoid caffeine consumption altogether. The recommended daily intake of caffeine varies depending on individual factors, such as age and health status, but generally, a moderate intake of caffeine is considered to be safe for most healthy adults.
