In recent years, many scientific studies have shown that moderate coffee consumption has a positive effect on cardiovascular health. Studies have found that there is a correlation between moderate coffee intake and a reduced incidence of heart disease and stroke risk. Antioxidant components in coffee, such as chlorogenic acid, can help improve vascular health, reduce inflammatory responses, and reduce the risk of arteriosclerosis.

Potential risks and negative effects of excessive coffee consumption

Although coffee has many health benefits, excessive consumption may have a series of negative effects. First, the stimulating effect of caffeine may lead to increased anxiety and tension.

For people who are chronically sleep deprived, frequent coffee consumption may aggravate insomnia and affect daily life and health.

An accelerated heart rate is another health risk associated with excessive coffee consumption. High caffeine intake can stimulate the heart, causing it to beat faster, leading to symptoms such as palpitations or irregular heartbeats. While most healthy adults can tolerate a certain amount of caffeine, for those with a history of heart disease or high blood pressure, excessive caffeine intake may lead to more serious heart problems.
