Is coffee addictive? The cause of coffee addiction

A colleague who used to work together went backstage to make a cup of coffee every hour or two, and she showed an unstoppable expression after every sip. She also wants to quit and doesn't want to be as addicted as smoking, but she can't help it. Coffee, which makes people want to give up, but also reluctant to give up, now finally know why it has so much magic.

Drinking coffee can be refreshing, coffee also contains high-content polyphenols, antioxidant function, but drinking coffee can be addictive? How to deal with it if you become addicted.

Generally addictive drugs, such as amphetamine, cocaine, morphine and nicotine, trigger the activity of the nucleus accumbens. Niehlig's experiment found that when the concentration of caffeine was increased to 5 mg / kg, the nucleus accumbens did not show any activity. However, when the concentration was increased to 10 mg / kg, the activity of the ipsilateral nerve increased significantly, but at this concentration, every part of the brain was quite excited. Therefore, caffeine has no specific effect on the nucleus accumbens. Other abuse can cause addictive drugs to specifically affect the nucleus accumbens at low concentrations. So caffeine is not addictive.

Although pharmacology proves that drinking two or three cups of coffee a day is not addictive. But many people will say, "I just can't stop drinking coffee!"this is a psychological effect. Drinking coffee has become a habit, and drinking one or two cups of coffee a day can often cheer you up and make you feel good, because coffee is really a brain stimulant.

But the metabolism of coffee slows with age. When you are young, drinking two or three cups of coffee will not affect sleep, but in your first to fifty years of age, drinking one cup after 05:00 in the afternoon may cause insomnia and cause your kidneys to urinate. Getting up at night to go to the toilet will also affect the quality of sleep.

Drinking coffee has become a habit. If you want to change it for a while, there will be addictive changes, and you will feel headache, irritability or laziness. If you really want to reduce or stop drinking coffee, it's best to take your time and mix caffeinated and decaffeinated coffee from more to less, and eventually to decaffeinated coffee (decaf). A cup of decaf contains only three milligrams of caffeine.

So often when we say that coffee is addictive, have we ever thought that we can't control our habits?
