On average, adults tend to sleep between 7 ½ & 8 hours
per evening. While the exact functionality of sleep is unknown, most evidence
points towards the idea that a lack of it can result in a variety of
consequences, including breathing impairments, depression, and heart disease.
In addiction, daytime exhaustion due to lack of rest is often attributed to
impaired occupational and social function, memory deficits, and automobile
accidents.
The consumption of alcohol has been seen to cause sleep
disorders by way of disrupting the duration and sequence of the various sleep
states and altering the amount of total sleep time.
Non-Alcoholic
Following the initial stimulation post consumption, alcohol
ingested around bedtime may work to decrease the amount of time necessary to
fall asleep. Due to its sedating effects, many individuals suffering from
insomnia use alcohol as a way to ensure a quick and easy transition into
dreamland. Unfortunately, studies show that the alcohol consumed within the
last hour before sleep may actually serve in disrupting the end half of the
sleep cycle. As such, those who utilize alcohol as a sleep tool may often
experience fits of daytime sleepiness and fatigue.
Alcoholic
Sleep disturbances that are attributed to alcoholism include
frequent awakenings, a decrease in sleep quality, and a prolonged pre-sleep
period. Hasty consumption reductions in alcoholics may result in alcohol
withdrawal syndrome, including insomnia and fragmented sleeping patterns.
Recovery
Aside from minor improvements following the initial
withdrawal period, sleep patterns in recovering alcoholics run the risk of
never returning to normal. Studies show even abstinent alcoholics to suffer
from poor sleep quality, with increased sleep fragmentation and decreased SWS.
Ipso facto; relapse in severe alcoholics may result in increased SWS and
decrease sleep fragmentation. Though this improvement may work to promote
relapse to a small extent; in time, sleep disruption will once again rear its
ugly little head.
