Does coffee really wake you up?
According to a new study published in the journal Neuropsychopharmacology, it’s a myth that a cup of coffee is needed to make your brain more alert in the morning. The study of 379 people showed regular coffee drinkers needed a hit of caffeine to bring them up to the same level of alertness as non-coffee drinkers. Researchers deprived each person of coffee for 16 hours before giving the participants either caffeine or a placebo. Each person then underwent a series of tasks to measure their attentiveness, memory and vigilance. We don’t gain any advantage from consuming caffeine.
