Someone once described coffee ---- "Nothing happens until you have a cup of coffee." ”
This black fruit native to Ethiopia, along with the development of society, has now become a life drink with the characteristics of the times, and has become one of the three major beverages in the world.
Coffee itself is also evolving, and by changing the way it is made, the taste of coffee can be different to cater to the needs of different groups of people.
You think drinking coffee refreshes your mind, but in fact it's just a "ritualistic" self-suggestion
Some researchers have found that for people who drink coffee for a long time, coffee does not really motivate them to lift their spirits, and drinking coffee is just a ritual.
As early as 2007, the University of Brosto conducted a research survey on this phenomenon and found that people who drink coffee regularly develop tolerance.
They will feel the withdrawal response after waking up in the morning because they have not been stimulated by caffeine for a night, and when they drink coffee, the effect of coffee will alleviate the withdrawal reaction to a certain extent, making them more awake and comfortable.
The problem is that their brains don't produce higher levels of stimulation than normal, and drinking coffee simply gets them "back to normal," even though they have the illusion of being "more awake after drinking coffee."
Is drinking coffee addictive?
Coffee contains caffeine, a neurotransmitter that stimulates the body's nervous system and keeps the body's brain at a highly hyperactive level.
As the literary master Balzac said: "Coffee enters the stomach ... The human brain is aroused as if it were about to usher in a great war. ”
So that's why many people feel that coffee is bitter at first, but soon feel the excitement and joy that coffee brings and can't leave.
Remember these 4 points, you can also drink coffee healthily
When drinking coffee, keeping in mind the following four points, you can avoid this situation and allow yourself to have a healthy body while enjoying coffee.
1. Drinking time
In fact, drinking coffee before going to bed is the most harmful to the body.
The caffeine in coffee will keep the brain in a highly excited state, and when the brain is in a state of excitement, the human body cannot quickly enter the sleep state, so that patients are prone to insomnia.
Drinking coffee after getting up in the morning is better, not only will not affect the patient's sleep, but also wake the patient from sleep, with a better posture to meet the new day, the patient's learning efficiency, work efficiency are of great help.
Second, the state of the body
Drinking coffee on an empty stomach is stronger than the stimulation of drinking coffee on a full stomach, and for some people with a lot of stomach and intestines, it is easy to damage the gastric mucosa, resulting in stomach pain and stomach bloating.
It is recommended that patients drink coffee one hour after meals, which can reduce the irritation of coffee, or when drinking coffee, they can also eat some small snack pads to pad their stomachs, which can also achieve good results.
Third, personal physique
For patients with high blood pressure, drinking coffee will cause vasoconstriction, and after vasoconstriction, the blood pressure in the body will rise significantly, resulting in aggravation of the patient's condition.
Patients with osteoporosis will have calcium loss in the body, and after drinking coffee, there will be a phenomenon of urinary calcium in the body, resulting in secondary loss of calcium, which in turn affects the recovery of the disease.
Fourth, contraindicated drugs
If you take a drug containing iron before drinking coffee, it will affect the efficacy of the drug.
This is because some of the ingredients in coffee can affect the absorption of iron, and coffee should be avoided after taking medications containing iron.
If you are not sure whether the medication you are taking contains iron, you can consult your attending physician and take it under the guidance of a doctor to prevent this from happening.
Can pregnant women and nursing mothers drink coffee?
In fact, as long as you pay attention to the amount of control, pregnant mothers and nursing mothers can drink coffee, and it will not harm the health of mothers and babies, so a large cup of coffee can be drunk to half.
For children, because the child's nervous system is not yet fully developed, it is more sensitive to caffeine, so it is best not to drink coffee.
As for adolescents aged 13-18 years, the daily intake of caffeine should not exceed 100 mg.
