Work is never complete without a mug of coffee, and sometimes several. This is especially true for people, who work night shifts. In such cases, sometimes even a cup of the strongest coffee does not help., therefore some people prefer to take a nap. New research suggests, that you can really cheer up, only if caffeine and sleep are combined!
The problem with short sleep is that people often feel sleepy after waking up. This can impair their performance for an hour. Drinking a cup of coffee after sleep can help shorten this time, although the stimulating effect of caffeine does not begin to appear until 20-30 minutes after drinking.
Many will say that the problem is solved! You just need to drink coffee after sleep, or not sleep at all, but simply recharge with caffeine. This is exactly what many people do. Instead of taking a short nap, they drink several cups of coffee throughout their shift. However, this can disrupt their sleep once they return home and go to bed.
That is why scientists at the University of South Australia decided the ideal formula of “vigor” so as not to feel tired after a short nap and not have problems falling asleep at home.
The researchers conducted an experiment. At 3:30 in the morning, they gave a group of subjects a dose of 200 mg of caffeine (the equivalent of one to two cups of coffee), immediately after which they went to take a 30-minute nap. They also gave a placebo to a control group and sent participants to sleep. When both groups woke up, experts observed them for 45 minutes after sleeping. Volunteers who drank coffee before bed showed the most significant improvements in performance.
“By drinking coffee before bed, people can get both the benefits of sleep and caffeine,” the authors of the work concluded. “It’s a win-win.”
