The Regulative Effect of Compound Rhodiola on Sleep Breathing Disorder at 5 380m Altitude

Objective To study the regulative effect of compound rhodiola on sleep breathing disorder at high altitude.Methods 16 subjects (age 18～21 years ) who had exposed to 5 380 m altitude for l year from 1 400 m, their sleep construction and change of sleep breath were recorded by CFM 8 polysomnoraphy before and after taking rhodiola capsule (2 #, 2/d ) for 24 days.Results As compared with those before administering medicine the percentage of sleep stages after taking rhodiola for 24 days were significantly decreased both in non rapid eyemovement (nREM) sleep Ⅰ (55.36±1.51 vs 47.97±1.57) and stageⅡ(26.56±0.46 vs 24.26±0.71),but there were significantly increased in the Ⅲ(7.02±0.56 vs 10.46±0.68), Ⅳ(5.81±0.48 vs 9.34±0.49) and the rapid eye movement (REM) sleep(5.25±0.20 va 7.89±0.84),the frequency of sleep apnea(SA,times/hour) and periodic breathing (PB,times/hour) were decreased (8.50±4.63 vs 4.25±2.76, 21.00±9.65 vs 11.75±6.25, P <0.05),and their duration time (seconds) were shorten(16.256±3.06 vs 12.25±2.43, 55.25±9.30 vs 42.00±3.38, P <0.05 or P <0.01).Conclusion It is suggest that rhodiola would improve sleep quality at high altitude.
