Study Says Coffee May Not Give You The Boost You Think It Does
PHILADELPHIA (CBS) -- Many among us rely on coffee to keep us awake. Some people don't even necessarily enjoy the taste, or the pungent aroma. They just want to keep their eyes open to get through the day while they're tired.
Well, according to new research, that coffee that you drink in the morning, may not being helping you stay awake at all.
A new study from the Sleep Research Society, and the American Academy of Sleep Medicine, found that after three nights of poor sleep, caffeine has "little to no benefit."
That's bad news for those of you who catch a few hours of sleep each night and rely on a cup of coffee to help you function. We all know someone who we can't speak to until they've had their cup.
Researchers tested the impact of coffee by restriction subjects to only five hours of sleep for five straight days. Compared to those who were given a placebo, researchers found that caffeine helped provide a boost for the first two days, but for the remaining three, it wasn't there.
So, if drinking coffee doesn't provide you a boost after a couple days, is it worth drinking?
A review published by the International Agency for Research on Cancer classified drinking very hot beverages as "probably carcinogenic to humans."
