People are always biased against caffeine, but in fact, moderate consumption of caffeine will bring many benefits to the human body. Caffeine is naturally found in our daily diet, such as tea, coffee and chocolate, which is a natural stimulant, painkiller, and has a magical effect on hair loss. Today, let me take a look at the five benefits of caffeine.

1 caffeine can clear your head

This is probably the main reason why people drink coffee. Caffeine prevents the brain from receiving adenosine monophosphate, which keeps the brain awake, helps you concentrate and reduces fatigue.

There is evidence that regular caffeine intake can prevent dementia (including Alzheimer's).

2 caffeinated shampoo can prevent hair thinning and hair loss

The problem of hair loss affects not only men, but also millions of women. But if you regularly use caffeinated shampoo, thinning and hair loss will be significantly improved.

Caffeine affects hair and scalp in two ways: one is to increase blood circulation in the scalp, and the other is to avoid the production of 5-α-reductase, which may lead to hair loss. Just touch the scalp for 2 minutes and caffeine will begin to take effect. It should be noted that this effect requires caffeine to touch the scalp directly, and drinking coffee does not have a similar effect.

Caffeine can enhance physical strength, perseverance and endurance

Athletes often use caffeine to improve their exercise. Studies have shown that caffeine can enhance muscle activity, especially upper limb muscles.

At the same time, caffeine can also improve muscle endurance, especially in long-distance running and cycling, can greatly improve the time and effectiveness of training.

4 caffeine promotes metabolism

If you take 200mg caffeine, your metabolic rate will increase by 7% over the next three hours, which means a significant increase in the rate of fat burning. Similarly, caffeine can help relieve pain because it can accelerate the effect of other painkillers.

Caffeine is an antioxidant

Antioxidants may be the greatest health benefits of coffee and tea, while caffeine doubles the efficacy of antioxidant phenols. Studies have shown that people who drink two or more cups of coffee a day have a 14% lower overall death rate than those who do not drink coffee.

The pros and cons of drinking coffee: close contact with coffee caffeine can stimulate the central nervous system and muscles, so it can cheer up, enhance thinking ability, and restore muscle fatigue. Acting on the cardiovascular system, it can improve heart function, dilate blood vessels and promote blood circulation. For the gastrointestinal system, it can help digestion and help decompose fat.
