Drinking coffee for a long time may have some adverse effects on the body, and these effects are related to the caffeine in coffee to some extent. Here's a detailed analysis of the possible adverse effects of long-term coffee drinking, as well as answers on whether it can cause hand shaking:

Adverse effects of long-term coffee drinking

Sleep disorders: Caffeine has the effect of stimulating nerves, and long-term intake may cause the brain nerves to be in a state of continuous excitation, which in turn can cause sleep disorders, such as difficulty falling asleep, shallow sleep, or dreaminess. Obesity: Many people like to add sugar or milk to their coffee, and drinking sweetened coffee for a long time may lead to excessive calorie intake, which can induce obesity. Gastrointestinal discomfort: Coffee has a certain irritation, and long-term drinking may stimulate gastric acid secretion, affect the normal movement of the gastrointestinal tract, and even cause gastrointestinal spasms, causing stomach bloating, nausea, belching and other uncomfortable symptoms. Increased heart rate: Caffeine stimulates the sympathetic nervous system and increases adrenaline secretion, which increases myocardial contractility and increases heart rate. In the long term, it can adversely affect heart health. Interfere with calcium absorption: The oxalic acid in coffee may combine with calcium to form insoluble complexes, hindering the normal absorption of calcium in the intestines, and long-term consumption may lead to bone problems such as osteoporosis. Bad mood: Excessive caffeine intake may stimulate the nervous system and make people in a state of tension for a long time, which in turn can cause anxiety, irritability and other bad emotions.

The relationship between hand tremors and long-term coffee drinking

Drinking too much coffee over a long period of time does have the potential to cause hand tremors. This is mainly due to the stimulating effect of caffeine on the central nervous system, which increases neuronal activity, and some sensitive individuals may experience symptoms of hand tremors. In addition, caffeine can also increase the production of adrenaline, a stress hormone that can also trigger hand tremors. In addition, caffeine has a diuretic effect and may cause imbalances in water and electrolytes in the body, especially the loss of potassium ions, and low potassium levels may also cause muscle twitching and tremors, including hand tremors.

How to avoid adverse effects

Drink in moderation: Controlling your coffee intake is key. It is recommended that the daily intake of caffeine should not exceed 4 mg (about the equivalent of 0 cups of standard coffee). Avoid added sugar and too much milk: To reduce your calorie intake, opt for black coffee or coffee with a small amount of milk. Pay attention to the time you drink: Avoid drinking coffee before bedtime to avoid affecting the quality of sleep. Individual differences: Everyone has a different tolerance to caffeine, so adjust your coffee intake according to your body condition and reactions.

In conclusion, long-term excessive coffee consumption may have adverse effects on the body, including sleep disturbances, obesity, gastrointestinal upset, increased heart rate, interference with calcium absorption, and bad mood. Hand tremors are also a symptom that can be triggered by long-term excessive coffee consumption. To avoid these adverse effects, it is advisable to drink coffee in moderation and pay attention to when and how you drink it.
