Caffeine is the main ingredient in coffee and has a refreshing effect. Caffeine can stimulate the central nervous system, improve attention and concentration, and enable people to restore energy in a short period of time. Long-term and excessive intake of caffeine may lead to insomnia, anxiety, palpitations and other adverse effects. Caffeine may also affect calcium absorption and increase the risk of bone loss. The elderly need to be especially vigilant.

2. Impact on the digestive system: Drinking coffee on an empty stomach requires more caution

The caffeine and acid in coffee can irritate the gastric mucosa. Long-term and excessive drinking may lead to stomach diseases such as stomach pain and gastric ulcers. Especially drinking coffee on an empty stomach can more easily aggravate the irritation to the stomach. Coffee may also affect intestinal function, leading to constipation or diarrhea. People with digestive system diseases should drink coffee with caution.

3. Impact on cardiovascular health: Excessive drinking increases the risk

Studies have shown that excessive coffee consumption may increase the risk of cardiovascular disease. The caffeine in coffee can increase blood pressure and speed up heart rate, which may aggravate the condition for people who already have cardiovascular disease. Long-term and excessive intake of caffeine may also affect blood lipid metabolism and increase the risk of arteriosclerosis and thrombosis. Patients with cardiovascular disease should try to avoid or reduce drinking coffee.

4. Impact on sleep quality: causes of shallow sleep and insomnia

The caffeine in coffee has a stimulating effect, which will stimulate the nervous system and affect the quality of sleep. For ordinary people, drinking coffee at night may make it difficult to fall asleep or cause shallow sleep; for people who are prone to insomnia, drinking coffee may induce or aggravate insomnia symptoms. It is recommended to avoid drinking coffee at night, especially within a few hours before bedtime.

5. Affecting nutrient absorption: Affecting mineral absorption and metabolism

The caffeine and acid in coffee may affect the body's absorption of minerals, such as calcium and iron. Long-term and excessive drinking of coffee may affect bone health and hemoglobin synthesis. Caffeine may also interfere with the metabolism of other nutrients, which is not conducive to physical health. It is recommended that everyone pay attention to a balanced diet and drink coffee in moderation.

Although coffee has some harmful effects on the body, you can still enjoy its benefits if you drink it in moderation. The key is to control the amount and time of drinking, as well as consider your personal physical condition. When choosing a drink, we should look at the pros and cons of coffee rationally, make appropriate decisions based on our own circumstances, and maintain good work and rest and eating habits, which are the key to maintaining good health.
