Forbes’s publication identifying coffee’s sweet spot for stress reduction and mood improvement has immediate productivity implications because the same two-to-three cup daily dose that lowers stress also delivers the optimal cognitive enhancement for sustained knowledge work.

For productivity-focused professionals, the sweet spot finding provides the definitive daily target that replaces the uncertainty of should I drink more or less with the precision of two to three cups, or equivalent, consumed between 9 AM and 2 PM, is the evidence-backed optimum that balances every health and performance dimension that thirty-seven briefings of research have evaluated.
