Coffee has been very popular in recent years. It is not only the favorite drink of young people, but also the refreshing effect of coffee is welcomed by many people. Now many young people are addicted to coffee, but constant drinking will also bring some effects to us, especially for some female friends, long-term drinking of coffee will have a great impact on their body. . 1. Nervous tension The reason why coffee has a good refreshing effect is that it contains a large amount of caffeine, which can excite the nervous system and greatly improve our work efficiency. However, if we drink too much caffeine, it will cause excitement of the nerve center and lead to insomnia or nervous tension. Therefore, experts remind you not to drink any caffeinated beverages within four hours before going to bed at night, so as not to seriously affect your sleep at night. In addition, excessive coffee intake may cause tinnitus, hyperfunction of the heart, increased pulse rate and uneven pulse beats, which are all hazards of excessive coffee drinking. 2. Drinking too much coffee in daily life may aggravate the condition of patients with high blood pressure and heart disease. This is definitely not alarmist. Patients with heart disease and other diseases should not drink coffee. In addition, for patients suffering from hypertension, arteriosclerosis, etc., coffee should be resolutely avoided. Because long-term or excessive drinking of coffee is likely to cause cardiovascular disease, especially for patients who already have high blood pressure. Drinking in large quantities will make your condition more serious. This is because caffeine can increase blood pressure, and the emotional tension caused by caffeine stimulating the central nervous system will lead to a multiplying effect on the risk factor. Experts remind that each person's daily caffeine intake must be controlled within 200 mg, which is no more than three cups. 3. Some middle-aged and elderly women with osteoporosis should not drink excessive coffee in their daily lives. Women of this age group are prone to calcium deficiency. If they drink excessive coffee at this time, it will inevitably lead to more serious calcium loss. Especially for some postmenopausal women, they need ten times the amount of calcium every day. If they drink coffee for a long time at this time, it will easily cause bone loss, and it will also have a great adverse effect on the preservation of bone mass, and may even lead to osteoporosis. Therefore, in addition to drinking less or no coffee in daily life, these women should also pay attention to eating more foods rich in calcium, such as seafood, soy products, etc. Through the above introduction, we should also understand some of the effects that long-term coffee drinking brings to us. But then again, drinking some coffee appropriately is also helpful to our body, because coffee contains enough caffeine to promote blood circulation. However, women should avoid excessive coffee during menstruation, otherwise it is easy to cause lower abdominal pain during menstruation. |
