Consisting of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication ...
Low doses of alcohol (one 360.0 ml (13 imp fl oz; 12 US fl oz) beer) are sleep-promoting by increasing total sleep time and reducing awakenings during the night.The sleep-promoting benefits of alcohol dissipate at moderate and higher doses of alcohol (two 12 oz. beers and three 12 oz. beers, respectively).

We'd even go so far as to say it's better than Coke straight from the can or bottle (and that's even including Mexican Coke). You've probably heard other people wax poetic about the merits of ...
The drink has also aroused criticism for its use of caffeine, which can cause physical dependence (caffeine dependence), [23] and can reduce sleep quality. [24] Many soft drinks in North America are sweetened mostly or entirely with high-fructose corn syrup (HFCS), rather than white sugar.
Sleep efficiency (SE) is the ratio between the time a person spends asleep, and the total time dedicated to sleep (i.e. both sleeping and attempting to fall asleep or fall back asleep). It is given as a percentage. [1] SE of 80% or more is considered normal/healthy with most young healthy adults displaying SE above 90%.
