Caffeine is a common ingredient in us, what are its advantages and disadvantages

Caffeine is a natural stimulant found in foods such as tea, coffee, and cocoa that can improve fatigue resistance and is loved by office workers. Everything has two sides, so what are the advantages and disadvantages of caffeine?


The advantages of caffeine

1. Caffeine can clear your mind

Caffeine blocks the brain's ability to receive adenosine, which keeps the brain awake, help you focus and reduces fatigue.


2. Caffeinated shampoos can prevent hair thinning and hair loss

Caffeine affects the hair and scalp in two ways: by increasing blood circulation to the scalp, and by preventing the production of 5-alpha-reductase, which can lead to hair loss. The caffeine kicks in after just 2 minutes of contact with the scalp. It should be noted that this effect requires caffeine to directly contact the scalp, and drinking coffee does not have a similar effect. 


3. Caffeine boosts stamina, perseverance, and endurance

Athletes often use caffeine to enhance their performance. Studies have shown that caffeine can enhance muscle activity, especially in the upper extremity muscles.


4. Caffeine boosts metabolism

With 200mg of caffeine, your metabolic rate will increase by 7% in the next 3 hours, which means that the rate of fat burning will be greatly increased.


5. Caffeine is an Antioxidant

Antioxidants are perhaps the greatest health benefits of coffee and tea, and caffeine doubles the effects of antioxidant phenolics.
