Coffee keep you alert! Caffeine, the most commonly consumed psychoactive drug in the world, is a stimulant. There are many studies showing that ingesting caffeine helps workers perform better, especially if they're working when their circadian clocks say that they should be sleeping.
Coffee eases the pain of working at a desk. There's a reason why computer programmers are so wired: Consuming caffeine has been found to ease pain in the neck, shoulders, forearms, and wrists that are often experienced by those of us who are chained to our keyboards.
Coffee is a social lubricant. Researchers found that employees who take coffee breaks together are more productive.
The best time for a coffee is around 2 p.m. The UK's National Health Service thinks energy levels are at their lowest at about 2:16 pm. The amount of time it takes for coffee to kick in depends on a number of factors -- including age, weight, gender and caffeine tolerance level --but 15 to 30 minutes is a pretty good window. Pro tip: Supercharge your rejuvenation with a caffeine nap. A cup of coffee followed by a 15-minute snoooze. By the time you wake up, the drug should be kicking in.
