According to the report of Life Helper on the Life Channel of Shandong Radio and Television Station: Drugs that are generally addictive, such as amphetamines, cocaine, morphine and nicotine, can trigger the activity of the nucleus accumbens. Nilig's experiment found that when the concentration of caffeine was increased to 5 mg/kg, the nucleus accumbens did not show any activity. However, if it was increased to 10 mg/kg, the activity of the accumbens nerve increased significantly, but at this concentration, every part of the entire brain was quite excited. Therefore, caffeine does not have a specific effect on the nucleus accumbens. Other abused addictive drugs can specifically affect the nucleus accumbens at low concentrations. Therefore, caffeine is not addictive.

Although pharmacological evidence shows that drinking two or three cups of coffee a day will not cause addiction, 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 comfortable, because coffee is indeed a stimulant for the brain nerves. However, the metabolism of coffee will slow down with age. When you are young, drinking two or three cups of coffee will not affect your sleep, but once you reach the age of fifty, if you drink one cup after five o'clock in the afternoon, you may suffer from insomnia, and it will cause the kidneys to urinate more, and you have to get up at night to go to the toilet, which will also affect the quality of sleep.

Disadvantages of coffee:

1. Adding to the chaos when you are nervous

Caffeine helps improve alertness, sensitivity, memory and concentration. But drinking more coffee than you are used to can produce a stimulant effect similar to the same dose, which can cause jitteriness. For people prone to anxiety disorders, caffeine can make symptoms such as sweaty palms, palpitations and tinnitus worse.

2. Aggravate high blood pressure

Because of its analgesic effect, caffeine is often combined with other simple analgesics. However, long-term and large-scale use will only make your condition worse if you already have high blood pressure. Caffeine alone can raise blood pressure, and if emotional tension is added, it will have a dangerous multiplication effect. Therefore, people at risk of high blood pressure should especially avoid drinking caffeinated beverages when they are under great work pressure. Some people who have the habit of drinking coffee all year round think that they are immune to the effects of caffeine, but this is not the case. A study shows that after drinking a cup of coffee, blood pressure can rise for up to 12 hours.

3. Induce osteoporosis

Caffeine itself has a good diuretic effect. If you drink a lot of coffee for a long time, it will easily cause bone loss, which will have an adverse effect on the preservation of bone mass. For women, it may increase the threat of osteoporosis. But the premise is that you don’t have enough calcium in your daily food, or you don’t exercise often, and women after menopause will lose calcium due to lack of estrogen. These conditions plus a lot of caffeine may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still avoid giving up because of fear.
