You may not think of it! Caffeine in coffee has these functions

Caffeine can make you clear-headed

This is probably the main reason why people drink coffee. Caffeine can block the brain from accepting adenosine, which keeps the brain awake, helps you concentrate and reduces fatigue. There is evidence that regular caffeine intake can prevent dementia (including Alzheimer's disease).

Caffeinated shampoo can prevent hair thinning and hair loss

Hair loss is not only a problem for men, it also affects millions of women. However, if you regularly use shampoo containing caffeine, the phenomenon of hair thinning and hair loss will be significantly improved.

Caffeine affects the hair and scalp in two ways: first, it increases blood circulation in the scalp, and second, it prevents the production of 5-alpha-reductase, which can cause hair loss. Caffeine only needs to be in contact with the scalp for 2 minutes for it to start taking effect. It should be noted that this effect requires direct contact of caffeine with the scalp, and drinking coffee does not have a similar effect.

Caffeine can enhance physical strength, perseverance and endurance

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

At the same time, caffeine can improve muscle endurance, especially in long-distance running and cycling, which can significantly increase the time and effect of training.

Caffeine boosts metabolism

After taking 150mg 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. Similarly, caffeine can assist in pain relief because it can accelerate the effect of other painkillers.

Caffeine is an antioxidant

Antioxidant properties may be the greatest health benefit of coffee and tea, and caffeine can double the effectiveness of antioxidant phenols.

Everything has its advantages and disadvantages. Although drinking coffee normally will not lead to such serious consequences as death, caffeine itself has many unexpected effects. However, drinking too much coffee can also cause symptoms such as palpitations, chest tightness, anxiety or insomnia.

So, for those who believe that they will die if they don’t drink coffee, this is good news. But please note that although coffee is delicious, don’t drink too much!
