Sirshasan is supposed to increase blood flow to the brain and considered to be beneficial for intellectual function, however mastering these techniques may be difficult.
To see the effect of headstand using a tilt table on heart rate variability (HRV).
A cross-sectional study that was done on 26 healthy volunteers.
HRV was assessed in the supine position and 30° head tilt position for 5 min. HRV recording was done on the power lab (AD Instruments P Ltd, Castle Hill Australia). The tilt table used was Medica Podium, New Delhi, HLT-200.
Paired -test.
All the HRV parameters showed non-significant change except low-frequency parameters which showed significant change during head tilt.
Headstand to a 30° using tilt table cause a decrease in the autonomic activity which is mainly because of decrease in sympathetic activity.
头倒立被认为可增加脑部血液流动，并被认为对智力功能有益，然而掌握这些技巧可能很困难。
观察使用倾斜台进行头倒立对心率变异性（HRV）的影响。
对26名健康志愿者进行的横断面研究。
在仰卧位和30°头倾斜位评估HRV 5分钟。HRV记录在功率实验室（澳大利亚城堡山AD Instruments P有限公司）进行。使用的倾斜台是新德里的Medica Podium，HLT - 200。
配对t检验。
除低频参数在头倾斜期间显示出显著变化外，所有HRV参数均显示无显著变化。
使用倾斜台进行30°头倒立会导致自主神经活动降低，这主要是由于交感神经活动减少所致。
