Summary

Squatting significantly raises blood pressure (BP), especially in hypertensive individuals. This posture is linked to a higher incidence of stroke, particularly hemorrhagic stroke, suggesting avoidance for at-risk populations.

Area of Science:

  • Cardiology
  • Neurology
  • Public Health

Background:

  • Squatting is a common toilet posture in India.
  • Elevated blood pressure is a major risk factor for stroke.

Purpose of the Study:

  • To investigate the effect of squatting on blood pressure.
  • To explore the association between squatting posture and stroke occurrence.

Main Methods:

  • Measured blood pressure changes in healthy volunteers and hypertensive patients during squatting.
  • Analyzed stroke onset data (time, place, posture, activity) in stroke patients.

Main Results:

  • Squatting caused a significant rise in systolic blood pressure (SBP) in healthy individuals and a greater rise in both SBP and diastolic blood pressure (DBP) in hypertensive patients.
  • Over a third of stroke patients experienced stroke onset in toilets, with 36% occurring during squatting, and more than half of hemorrhagic strokes happened in this position.

Conclusions:

  • Squatting significantly increases blood pressure, particularly in hypertensive individuals.
  • The squatting posture is associated with stroke occurrence, especially hemorrhagic strokes.
  • Hypertensive individuals and those at risk of stroke should avoid squatting; physicians should consider squatting BP during monitoring.
