Changes in Body Water Caused by Sleep Deprivation in Taeeum and Soyang Types in Sasang Medicine: Prospective Intervention Study

Abstract EN

Background.

There is a negative relationship between sleep deprivation and health.

However, no study has investigated the effect of sleep deprivation on individuals with different body composition.

The aim of this study was to determine the differential effect of sleep deprivation in individuals with different body compositions (fluid) according to Soyang type (SY) and Taeeum type (TE).

Methods.

Sixty-two cognitively normal, middle-aged people with normal sleep patterns were recruited from the local population.

The duration of participants’ sleep was restricted to 4 h/day during the intervention phase.

To examine the physiological changes brought on by sleep deprivation and recovery, 10 ml of venous blood was obtained.

Results.

Total Body Water (TBW) and Extracellular Water (ECW) were significantly different between the groups in the intervention phase.

Physiological parameters also varied from the beginning of the resting phase to the end of the experiment.

Potassium levels changed more in SY than TE individuals.

Conclusion.

Participants responded differently to the same amount of sleep deprivation depending on their Sasang constitution types.

This study indicated that SY individuals were more sensitive to sleep deprivation and were slower to recover from the effects of sleep deprivation than TE individuals.
