Whether or not to drink coffee without paying attention to time is harmful to health.
Coffee contains caffeine, which excites the sympathetic nerves after entering the body, thus eliminating drowsiness, improving blood circulation, and the body also feels warm and does not feel tired, so it has a "refreshing" effect. However, when the sympathetic nerve is stimulated and excited, it has a negative effect on appetite, that is, appetite will be reduced, so drinking coffee before a meal will not want to eat. In addition, due to the stimulation of the stomach and the increase of gastric juice secretion, stimulating the empty stomach is disadvantageous to patients such as gastric ulcers. This can be said to be the negative effect of coffee. But drinking after a meal is helpful to digestion because the secretion of gastric juice will increase. Therefore, there is absolutely no problem with drinking after a meal.
In addition, some people think that adding some milk to drink can ease its irritating effect, but how much of a small amount of milk can neutralize caffeine, unless it is half milk and half coffee, mixed with coffee milk or milk coffee, may have some effect. For example, coffee and milk for breakfast, because there is more milk than coffee, although it is drunk on an empty stomach, it still has the effect of relieving gastric juice. Ideally, drink after a meal, which is beneficial but harmless.
As a result of allergic parasympathetic nerve excitation caused by asthma or allergic rhinitis, if it can promote sympathetic nerve excitement, inhibit parasympathetic nerve, it will help to prevent the attack. Especially serious allergic patients, some mild incentives can cause physical discomfort, coupled with psychological fear of allergies, often out of control.
Therefore, it is recommended to make use of the advantages of caffeine to drink a cup of coffee in advance when allergies and asthma are about to occur (the patient feels it), which is quite preventive. In addition to the excitatory effects of caffeine, patients who have "already had coffee" on sense of security are less likely to attack. Of course, as the saying goes, "going too far is not as good as it is". No matter how good it is, we have to "enough is enough".
Otherwise, regardless of drinking before and after meals, excessive caffeine will lead to hyperpalpitation (the heart beats violently), and even side effects such as trance, unstable walking center and so on. Watch out! Excessive consumption of caffeinated drinks can easily lead to kidney stones. In principle, two to three cups of coffee a day is appropriate. If you drink four or five cups, most people will feel sick, so be careful. In principle, no more than three cups a day is best for any kind of irritating drink.
