Yes, it should be obvious that caffeine does cause you to not sleep…so the obvious solution? Just don’t drink coffee couple hours before bedtime.

Studies have demonstrated that caffeine disrupts sleep. When caffeine is consumed immediately before bedtime or continuously throughout the day, sleep onset may be delayed, total sleep time reduced, normal stages of sleep altered, and the quality of sleep decreased.

Caffeine’s effects on sleep appear to be determined by a variety of factors including dose, the time between caffeine ingestion and attempted sleep, and individual differences in sensitivity and/or tolerance to caffeine.

Caffeine-induced sleep disturbance is greatest among individuals who are not regular caffeine users. Although there is evidence for some tolerance to the sleep disrupting effects of caffeine, complete tolerance may not occur and thus habitual caffeine consumers are still vulnerable to caffeine-induced sleep problems.

A lot of mis-happenings in the world could have been avoided if it wasn’t for lack of sleep…

People in many high stress professions—such as medicine, law enforcement, or the military—often have to make quick decisions when they’re not well rested. New research confirms what common sense has long held: People don’t do their best thinking when they’re sleep-deprived.

Here’s an interesting site that has various sex positions illustrated using figures. Hilarious! (Not intended for anyone under 18 years of age!)

Check out this REM graph for referencing how REM sleep works.

This is just a simple graph of the typical sleep cycle.I know this data is readily available, but it’s really nice to have it in a large, clean, graph format. Having this information really helps you know specifically when you should wake up, based on how long it takes to fall asleep. It should be noted however, that this chart is based on subjects that were not under the effects of any sleep altering substances, like alcohol.
