My third night of testing fell on the evening before a big deadline, so my mind was nudging around what I needed to do the next day. (Image credit: Getty/FreshSplash) Night 3 Within about 10 minutes I was asleep again – and had a vivid dream about shooting stars. I did wake up in the middle of the night, but instead of using my trusty 4 7 8 sleep method, I jumped back into this video. I didn’t make it through more than 20 minutes before yanking out my Airpods and falling asleep. By the time bedtime rolled around I was looking forward to taking another dive into this sleep meditation and focusing my mind on stars, not work.Įven though I felt wired earlier in the evening, the combination of my usual bedtime routine and this guided sleep meditation soon took effect. Last night’s relaxing vibe stayed with me through the morning, but by the afternoon my growing to-do list was ramping up my stress levels. I vaguely remember taking my Airpods out of my ears before falling asleep, feeling relaxed and quiet of mind. I got about 35-ish minutes into the hour-long video before my eyes started to feel super-heavy. While this type of language isn’t for everyone, I’m kinda used to it after 11 years’ of yoga classes and endless guided sleep meditations. However I have to admit to a little eye-rolling when Jason said “you are the child of stars”. The big focus in the beginning is on letting go of your thoughts and to simply be in this sleep meditation, feeling safe, warm and quiet. Anyone who says “you are about to take a journey into the depths of relaxation” has my vote, and I could soon feel my body relaxing shoulders dropping, face softening. Investigators say that future research will focus on determining the contributions of each of these mechanisms of sleep apnea toward its effect on disruption of spatial memory.My day was really busy, so the chance to ditch my worries and focus instead on visualizing the night sky was a novelty. Second, sleep apnea creates numerous small arousals that interrupt sleep continuity. Sleep apnea is thought to have two main detrimental effects: First, it creates numerous repetitive dips in the blood’s oxygen levels. Sleep apnea is a common condition affecting four percent of Americans overall and as many as 25 percent of middle-aged men. Varga says that this suggests that sleepiness or lack of attention were not reasons for the decline in spatial memory, as indicated by the maze performance after experiencing sleep apnea in REM sleep. However, when REM sleep was disrupted by sleep apnea, there was not only no improvement from baseline testing, but, in fact, subjects took four percent longer to complete the maze tests.Įqually important, when sleep apnea occurred in REM sleep, subjects did not experience delayed reaction times on a separate test to measure attention, called a psychomotor vigilance test.ĭr. When sleep was aided by therapeutic CPAP all night, researchers observed a 30 percent overnight improvement in maze completion time from their baseline examinations. CPAP was maintained at the therapeutic level during all other stages of sleep. On the other night, their use of CPAP was reduced during REM sleep, thus allowing sleep apnea to occur. Then, during one night’s sleep, subjects used their therapeutic CPAP as they normally would at home. They used a joystick to navigate through one of two unique, computer-generated 3D spatial mazes. Subjects were first given a baseline examination using the video games before any observation of their sleep patterns.
