Sleep-Deprived? Cut the Coffee and Take the Stairs Instead
A new study of 18 sleep-deprived women compared different interventions and measured their alertness and energy. The study found that climbing stairs was more energizing than a low dose of caffeine.
The subjects in the study were all physically active, healthy college-aged women with a history of chronic sleep deprivation. A 10 minute bout of stair walking at a moderate intensity gave the women increased feelings of energy and alertness, while low doses of caffeine were less effective.
