Alcohol and caffeine together have a surprising effect on sleep: study

A study conducted by researchers from the University of Washington and the University of California, Berkeley found that the combination of caffeine and alcohol actually offsets the negative impacts that each substance has on sleep quantity and quality.
On average, caffeine consumption reduced sleep quantity by 10 minutes per cup consumed the previous day, while alcohol consumption led to a 4% decline in sleep quality.
However, the researchers caution that this offsetting effect is only short-term and may contribute to a cycle of self-medication with alcohol and caffeine to mitigate sleep issues, which in turn perpetuates negative sleep patterns.
