Is it unethical to pay cheap wages or are companies doing those workers a favor?
Follow TIMEHealth Having a drink or two is one way to nod off more quickly, but how restful is an alcohol-induced slumber? The latest research, published in Alcoholism: Scientists reviewed 20 studies that included participants who were tested in 38 sleep laboratory experiments.
The volunteers drank varying amounts of alcohol, ranging from a low of one to two drinks, a moderate amount of two to four drinks, to a high of four or more drinks. While some experiments examined the results of only one night of drinking, others extended into several consecutive nights.
Most of the participants were healthy young adults, and none had drinking problems.
That presents a more complicated picture of how alcohol affects sleep, and the trade-off may have implications for understanding how sleep can impact overall health as well.
At all doses studied, alcohol increased deep or so-called slow-wave sleep SWS during the first part of the night. This type of slumber is associated with healing and regeneration of bones, muscles and other tissues, as well as maintaining a strong immune system.
It May Be Affecting Your Memory In contrast, drinking has long been known to reduce REM sleep, the deepest sleep stage in which most dreams occur and during which memories are likely stored and learning occurs.
One or two drinks, for example, can increase slow-wave sleep while not affecting deeper REM sleep.
But more alcohol can cut into the time spent in the REM stage. So that nightcap may be helpful in getting you to doze off, while a wild night of heavy drinking is likely to make you more restless.
