A study published in the journal Nutrients suggests that women who drink coffee may reduce their risk of sleep disorders.
Researchers in the Netherlands conducted a study to investigate whether coffee consumption negatively affects sleep quality, shortens sleep duration, and causes sleep disorders in older adults.
In the study, scientists utilized data from a long-term aging project involving residents of Amsterdam from 2018 to 2019. Volunteers were asked to complete a questionnaire regarding their sleep health parameters, daily coffee consumption habits, and the presence of sleep disorders.
The results indicated that the relationship between caffeine consumption and sleep in older adults significantly varies by gender. Notably, older women who do not consume caffeine have a higher risk of sleep disorders compared to those who do. This pattern was not observed in men.

Overall, the study shows that sleep quality and caffeine consumption have a gender-specific relationship. Older women who abstain from caffeine tend to have shorter, more irregular sleep compared to those who consume it. The researchers also found no connection between increased caffeine consumption and poor sleep quality.
However, these findings somewhat contradict previous studies. A study conducted in Europe indicated that individuals with high coffee consumption tend to have shorter sleep durations. The authors of the new research believe that the discrepancy lies in how caffeine intake is assessed.
In addition to its effects on sleep, experts also discovered that caffeine may help reduce the risk of type 2 diabetes, cardiovascular diseases, and mortality from various causes.
