    A new study suggests that caffeine intake
    six
    hours before bed can have a significant and devastating effect on sleep."
    experts have long suspected that caffeine can still disrupt sleep after a long period of time.
    M. Safwan Badr, president of the
    American Academy of Sleep Medicine

    , said
    "
    the study provides objective evidence to support
    's general recommendation that avoiding caffeine in the late afternoon and
    nights is good for sleep.
    ”The results showed that
    400mg
    caffeine (about
    2-3 cups of coffee) was significantly affected by
    400mg of caffeine (about
    2-3 cups of coffee) in the three hours before bed, or even
    6hours before bed. Even after 6

    hours of caffeine intake before bedtime, the total amount of sleep objectively measured was significantly reduced (at least one hour). Subjective reports, however, showed that participants were not aware of the sleep disorder.study was published in the Journal of Clinical Sleep Medicine, published by the American Society of Sleep medicine
    Journal of Clinical Sleep Medicine
    Journal.Dr Christopher Drake
    said

    's drink of a large cup of coffee on the way home from work had the same negative effect on sleep as caffeine intake at bedtime.
    "

    Henry Ford Sleep Disorders and Research Center
    , an associate professor of psychiatry and behavioral neuroscience at Wayne State University in Detroit, Michigan,
    and a director of the Sleep Research Institute. He noted
    "
    people are less likely to notice that caffeine intake in the afternoon can have a devastating effect on sleep at night."
    ”Drake
    team identified
    healthy
    as sleep subjects through physical examination and clinical conversations. Participants were asked to maintain their normal sleep duration. For

    days, they took
    3
    pills a day for
    6
    hours,
    3,
    hours before their scheduled sleep time, and before bedtime.
    3
    pills, one contained
    400
    mg of caffeine and
    2
    as a placebo. Of
    four
    days,
    3
    pills on one day were placebos. Sleep disorders are subjectively measured using standard sleep logs and objectively measured by home sleep monitors.study was the first to investigate the effects of a given dose of caffeine taken at different times before bedtime, the authors said. The results showed that people should generally avoid caffeine

    5 p.m. to ensure a healthy night's sleep.
