Navy SEALs and Coffee

Did you know that Navy SEALs have studied coffee?

Yes, they found that 16.667 ounces is the perfect amount.

When humans are acutely exposed to multiple stressors, cognitive performance is substantially degraded. Few practical strategies are available to sustain performance under such conditions.

Objective: This study examined whether moderate doses of caffeine would reduce adverse effects of sleep deprivation and exposure to severe environmental and operational stress on cognitive performance.

When cognitive performance is critical and must be maintained during exposure to severe stress, administration of caffeine may provide a significant advantage.

A dose of 200 mg appears to be optimal under such conditions.
