Improve physical performance
Caffeine has also been shown to have enhanced performance effects on body performance.
Caffeine stimulates the release of adrenaline, a hormone that increases heart rate, enhances metabolism, and helps the body obtain stored fat for energy.
These effects can improve physical performance, increase endurance and strengthen muscle strength and strength, making caffeine drinks a popular choice for athletes and fitness enthusiasts.
Increased metabolism
Caffeine has been found to increase the metabolic rate, which is the rate at which the body burns calories.
Studies have shown that caffeine can increase resting metabolic rates and enhance fat oxidation, which can help weight loss and weight management efforts.
However, it is important to note that the effects of caffeine on metabolism may vary and may be moderate, while other factors such as diet and exercise play a more important role in overall weight management.

Antioxidants are compounds that help neutralize harmful free radicals in the body, they are unstable molecules that can damage cells and cause a variety of health problems, including heart disease, cancer and neurodegenerative diseases, including chronic diseases.
Antioxidants in caffeine drinks, such as green acid in coffee and catechins in tea, are associated with potential health benefits and may contribute to the body’s overall antioxidant state.

For example, regular coffee consumption is associated with lower risk of developmental disease such as Parkinson’s disease, type 2 diabetes, liver disease and certain types of cancer.
However, more research is needed to fully understand the relationship between caffeine intake and disease risk, and individual factors such as genetics, overall diet and lifestyle also play an important role in disease development.
It is worth noting that individual responses to caffeine may vary, and excessive caffeine consumption can lead to negative effects such as increased heart rate, anxiety, insomnia, and digestive problems.
It is important to consume caffeine drinks in moderation and consider personal tolerance and health.
