What's robbing you of sleep? It may not be the caffeine, but might be your wine

* Drinking coffee or tea just before bed does not affect quality of sleep of people with insomnia, a new study has found.

*The study found that nicotine and alcohol, however, did disrupt sleep, with a pre-bed cigarette taking 42 minutes off total duration of sleep for study participants.

Drinking coffee or tea just before bed does not affect quality of sleep, a new study has found.

U.S. researchers from Florida Atlantic University and Harvard Medical School monitored 785 people for a total of 5,164 days and nights, recording how much caffeine, alcohol, and nicotine they consumed.

The team then compared their consumption to results from sleep diaries and wrist sensors which recorded the participants' sleep duration, sleep efficiency, and how quickly they woke up after drifting off.

The study found that while nicotine and alcohol did disrupt sleep - with a pre-bed cigarette taking 42 minutes off total duration of sleep for insomniacs (a person who is regularly unable to sleep) - caffeine seemed to have no effect.

Normally a glass or two of wine at dinner will not have a detrimental effect on sleep. but it's best to give yourself several hours prior to bedtime to metabolize it out.
