[10] In a study published in 1972, [11] during puberty, the average tumescence time per night was 159 min; average REM sleep time was 137 min.

Shows convergent validity with other symptom scales such as ESS and Karolinska Sleepiness Scale, [6] prediction of performance after sleep deprivation [4] Discriminative validity: Adequate: Studies do not report AUCs, some mention overlap between sleepiness, physical tiredness, and depression [4] Validity generalization: Good
The ESS generates a numerical score from zero (0) to 24 where a score of ten [10] or higher may indicate that the person should consult a specialist in sleep medicine for further evaluation. [12] [13] [14] Another tool is the Multiple Sleep Latency Test (MSLT), which has been used since the 1970s.

[46] [47] This is true not only of humans, but of many animals dependent on their parents for food. [48]
A number in the 0–9 range is considered to be normal while a number in the 10–24 range indicates that expert medical advice should be sought. [3] For instance, scores of 11–15 are shown to indicate the possibility of mild to moderate sleep apnea, where a score of 16 and above indicates the possibility of severe sleep apnea or narcolepsy.

Additionally, it is recommended that young adults (18–25 years) obtain 7 to 9 hours of sleep and avoid sleep less than 6 hours and more than 11 hours. Adolescent sleep researchers have conducted studies to provide stronger empirical evidence for sleep recommendations.
A new study suggests that sitting for 10.6 hours or more a day is significantly linked to future heart failure and cardiovascular death risk. ... strong associations with increased risk persisted ...
