Caffeine gives workers more than energy

Caffeine has long been the drug of choice for shift workers looking to stay awake on the job.

But new research finds it could do more than deliver a jolt of energy. Caffeine may help workers perform better and make fewer errors.

Tests show that workers who increased their caffeine had a boost in memory, attention span perception, and reasoning skills.

The study is from the Cochrane Group and focused mainly on workers in their 20's and 30's.

Most were getting their caffeine from coffee, tea or energy drinks.

More research is needed to determine how an increase in caffeine intake would affect older workers.
