New Observations on Coffee Intake and Mental Health
Researchers from Hangzhou Normal University have identified a link between how much coffee people drink and their risk of depression and anxiety disorders. The study suggests that a daily intake of two to three glasses of coffee may support better mental health. The findings were published in a peer‑reviewed journal focusing on clinical psychology and psychiatry.
During the study, more than 152,800 adults completed online assessments about their mental health and attitudes toward coffee. Among respondents, 81% reported drinking coffee. Within that group, 41% consumed two to three cups a day, 28% drank a single cup, and the remainder consumed more than three cups.
Analyses showed that the lowest risk of depression and anxiety appeared among those who drank two to three cups daily. Consuming more than six cups per day was associated with a sharp rise in the likelihood of developing depressive and anxiety disorders. Interestingly, two to three cups of instant coffee per day were linked to a reduced risk of depression, although they did not significantly impact anxiety.
Researchers noted that the mental health benefits persisted when coffee was enjoyed with milk, sugar, or other flavorings.
In their own words, the researchers stated that moderate coffee consumption—specifically two to three cups of ground coffee, café au lait, or unsweetened coffee—was associated with a lower risk of both depression and anxiety. They also suggested that moderate coffee intake could align with healthier lifestyle choices that support prevention and treatment of these conditions in the general population. Acknowledging the broader context, they added that this pattern might reflect a broader personal lifestyle rather than a simple dosage effect.
Prior investigations in the field have examined beverages that may influence metabolic rate and weight management, contributing to the ongoing discussion about how daily drinks intersect with overall health.
Note: The study emphasizes associations rather than definitive causation and calls for further research to clarify underlying mechanisms and potential confounding factors. (Source: Psychiatry Research)
