Sleep deprivation and stress: an inseparable pair

Stress in subjects undergoing sleep deprivation.

Psychological, physiological, and biochemical studies were conducted on 4 healthy young-adult males while they underwent 120 hr. of sleep deprivation. The subjects quickly Formed a group and dealt with this contrived stress in much the same way that groups cope with stressful environments. Although it is concluded that sleep deprivation is stressful, our measurements did not show an adrenocorti...

Thalamus and cortex: inseparable partners in shaping sleep slow waves?

Editor's Note: These short, critical reviews of recent papers in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to summarize the important findings of the paper and provide additional insight and commentary. For more information on the format and purpose of the Journal Club, please see Review of Lemieux et al. Sleep slow waves have gained increasing ...

Energy expenditure during sleep, sleep deprivation and sleep following sleep deprivation in adult humans

Sleep has been proposed to be a physiological adaptation to conserve energy, but little research has examined this proposed function of sleep in humans. We quantified effects of sleep, sleep deprivation and recovery sleep on whole-body total daily energy expenditure (EE) and on EE during the habitual day and nighttime. We also determined effects of sleep stage during baseline and recovery sleep...

Sleep deprivation

Sleep deprivation, sleep apnea and cardiovascular diseases.

Sleep dramatically influences cardiovascular regulation. Changes in sleep duration or quality as seen in sleep disorders may prevent blood pressure to fall during sleep as expected in human physiology. This supports the increased prevalence of hypertension and drug-resistant hypertension in those with sleep loss. Other cardiovascular outcomes i.e. coronary lesions seem to be associated with sle...
