Study shows mini-doses of caffeine = more energy

A lot of people start their day with a big cup of coffee, hoping that the caffeine will invigorate them. But findings published today in the May issue of the journal SLEEP indicate that there might be a better way to stay awake for long periods. According to the report, low doses of caffeine administered at regular intervals may provide improved pick-me-up benefits. In the new study, the scientists instead tested the effects of administering an hourly, low dose of caffeine equivalent to about two ounces of coffee to one group, while the second group received a placebo. The caffeinated men performed better on cognitive tests than the control individuals did, and dozed off less often. And though they received the same cumulative dose as subjects in previous, single-dose studies, taking many small doses minimized some of the negative side effects that caffeine can have, such as tremors.
