Others drink coffee and become sober in the world, how can you get sleepy when you drink it?

In recent years, coffee has become a refreshing energy drink for many office workers and examination students. However, some people say that the more they drink coffee, the more sleepy they are, and even today they are on the hot search. So, let's talk about this topic today.

Why is the refreshing "artifact" coffee?

The reason why people are sleepy is because the body's energy source, adenosine triphosphate, is decomposed, and it will release adenosine to bind to the receptors, telling the brain that "Lao Tzu is going to sleep." Caffeine can be structurally similar to adenosine, when it binds to the receptor, adenosine can not transmit the signal of sleepiness, can only follow the caffeine up "hi".

Sleepy with coffee? See which shot you've been shot?

However, caffeine can't knock on everyone's door, there are always a small number of people who will be sleepy after drinking coffee, and there are several reasons for this!

1. Caused by genetic factors

If the CYP1A2, AHR, CYP2C9, and SDORA2A genes are not highly active in your body, then congratulations, you can sleep peacefully after drinking coffee.

2. The timing is not right

The time when caffeine works is about 45 minutes later, and if you are sleepy during these 45 minutes, it is actually normal, not that caffeine has no effect on you.

In addition, if you did not sleep the first night, the next day did not rest to continue to work, at this time tired of the dog, the adenosine in the body has long been "quick to board", therefore, drinking more coffee will not help you.

3. Usually drink too much coffee

If you're one of those types who can't get by without drinking two or three cups of coffee a day, it's likely that your body is intolerant to caffeine.

4. There is sugar in the coffee

Not everyone can accept the bitterness of American pure coffee, after all, life is already bitter enough. So, if you drink a mocha, latte, etc. with milk and sugar added, the same 200Ml coffee, the latter will have a lower caffeine content.

Coupled with a large number of added sugars in this kind of coffee, the speed of metabolism of such sugars is very fast, blood sugar will fluctuate greatly, insulin will be secreted in large quantities, increasing the concentration of tryptophan in the blood, then serotonin in the brain will produce melatonin, resulting in a drowsy feeling.

5. Body dehydration

The diuretic nature of caffeine can dehydrate the body, and the body will feel tired when it is dehydrated.

How to drink coffee correctly?

1. Drink in advance

As we mentioned, caffeine will "work" in about 45 minutes, so if you're sleepy at 2 p.m. every day, drink coffee around a minute. During this time, you can take a break in your body and mind. When caffeine works, the body is less prone to overdraft.

It should be reminded that the half-life of caffeine is 5-7 hours, if you don't want to sleep with your eyes open in the middle of the night, don't drink coffee within 5 hours before bedtime.

2. Drink in moderation

Although drinking coffee can be refreshing and has certain benefits for health, whether it is the general population or special people, it is necessary to drink coffee in moderation. Drink no more than 400ml of coffee per day. Especially pregnant women, it is necessary to control it within 200ml.

3. Drink pure coffee as much as possible

Although the taste of pure coffee is far less than that of mocha, caramel macchiato, cappuccino and other flavored coffees with added sugar and milk, the content of sugar and fat in such coffee is not low, and if you often drink such coffee, it may make you drink more and more fat.

Tips: Children, the elderly, and pregnant women should avoid drinking coffee. In addition, some diseased people should also avoid drinking coffee, such as those with gastroesophageal reflux symptoms, frequent migraines, poor sleep quality, difficulty falling asleep, and people with arrhythmias should avoid drinking.

This coffee is strongly not recommended for you to drink!

Presumably someone has already guessed it, yes! It's one of the most expensive coffees in the world – cat coffee! The price per pound is up to 3000 yuan.

Cat coffee is made from coffee beans in the poop of Indonesian musk cats. And because this musk cat is getting less and less, only 150 grams of coffee beans can be extracted from the excrement of each kilogram of musk cat, which is far from satisfying the businessman's desire to make money.

As a result, many wild musk cats are caught and imprisoned in cages, and more cat feces coffee is obtained by feeding them coffee beans.

These musk cats are timid by nature, and they are suddenly caught and fed non-stop, so that many musk cats suffer from stomach diseases and malnutrition, not only to endure mental torture, but also to bear physical torture. As a result, many musk cats die of a nervous breakdown and hunger strike. Because of its soft fur, it was reduced to raw material for the fur market after death.

These acts of trampling on living beings for their own selfish purposes should not only be condemned by everyone, but also should be resolutely resisted by everyone! Because if there is no buying and selling, there is no harm!
