Similar Assertions

During sleep deprivation, people with chronic insomnia don't show as much increase in parasympathetic activity at night compared to healthy people. This finding is from the abstract summary - full study details were not available

96%

Healthy sleepers show stronger sympathetic nervous system activity during sleep deprivation compared to those with chronic insomnia. This finding is from the abstract summary - full study details were not available

76%

Sleep deprivation increases sympathetic nervous system activity, elevating heart rate and vascular resistance, while restorative sleep enhances parasympathetic activity, reducing cardiac output and vascular resistance.
