Daytime Functioning
How you function during the daytime is directly linked to how tired you are, and daytime sleepiness is directly related to how much sleep you get. So what is keeping adults from sleeping? Nearly 50% of adults report experiencing one or more symptoms of insomnia at least a few nights a week in the past year. These symptoms include waking up feeling unrefreshed (34%) and being awake a lot during the night (32%). Having difficulty falling asleep and waking up too early are less common, but are still experienced at least a few nights a week by 23% of adults. Nearly 1 in 10 adults (9%) report experiencing pauses in breathing (sleep apnea) at least a few nights a week in the past year. These episodes generally result in sleep fragmentation and subsequent daytime sleepiness. Restless leg syndrome (RLS) - a "creepy crawling" feeling, tingling or other type of leg discomfort that requires movement of the limb to relieve the sensation - was reported by 13% of adults in the survey. This condition leads to difficulty initiating sleep, potentially reducing the total number of hours of sleep one gets.
