Similar Assertions

People with chronic insomnia show reduced low-frequency heart rate variability during sleep deprivation compared to those without insomnia. This finding is from the abstract summary - full study details were not available

79%

Both people with chronic insomnia and healthy sleepers experience increased parasympathetic activity at night during sleep deprivation. 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.

75%

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
