X. 3D AudioMagic™ Natural Sleep program during and after pregnancy

Studied: 3D AudioMagic™ Natural Sleep program during and after pregnancy
Conducted by: Kathy Lee, R.N., Ph.D., University of California at San Francisco
Funded by: National Institute of Health (NIH)

This study conducted on pregnant women found that after the birth of their babies, those women who used a specific series of AudioMagic™ adult Natural Sleep programs in combination with Cognitive Behavioral Training for Insomnia (CBT-I) materials slept nearly one hour longer than the control group.

I would be remiss, however, in leaving out that during their third trimester of pregnancy, the women using the adult sleep programs with CBT-I slept no better than those who did not. 

It would appear that sleeping late in pregnancy is a challenge for many women, for which there is still not a good solution. However, given that the AudioMagic™ Natural Sleep programs and CBT-I materials performed so splendidly at improving sleep during the critical postpartum period (when many women are inclined to experience a degree of depression) the apparent failing of the programs to help improve sleep in the third trimester is assumed to be the result of two factors:

  • the women not yet having enough experience using the programs
  • a general trend among pregnant women of less sleep disturbance in the third trimester than postpartum

There is evidence of both of these factors (particularly well-documented in the case of the latter: Lee et al, 1992, Goyal et al 2002). The evidence of the former comes from the above-mentioned Air Force study, in which the subjects reported that it had taken them approximately 4-6 weeks to feel they had learned or been adequately “trained” in the program (Alsten et al. 1999).

Based on the recommendations of childbirth class instructors and other pregnancy sleep experts we reduced the length of program use in the study to 4 weeks, in order to make it more acceptable to first-time pregnant mothers who are generally already overwhelmed with things to do. Based on the postpartum results this condensed period of program use seems effective, but perhaps an extended period of program use during the pregnancy would provide more adequate results during the pre-delivery time period.

In addition, the effect of program use may become more evident if those women who are at highest risk for prenatal sleep disturbance can first be identified.

The most significant objective improvement noted from the study was the previously mentioned additional hour (55 minutes, to be precise) in total sleep at night (postpartum). But that wasn't the only noted result or benefit.

The quality of that sleep was improved as well, with fewer awakenings, lower Wake After Sleep Onset (WASO) percentage, and less time to get to sleep initially and after awakening for nursing. This last factor, the time it takes to fall asleep, is known as Sleep Onset Latency (SOL) and it is a noteworthy finding in this study as it is considered the most relevant screening question in relation to the risk for postpartum depression (Goyal et al. 2007).

One additional objective improvement found was better napping during the day, which increased the overall sleep quantity in a 24-hour period to 81 minutes.

Several subjective measures improved as well, notable decreases both in reported levels of fatigue and perceived stress in the morning, and improvements in adjustment.

The report on this study states: "We consider an extra hour of consolidated sleep during the postpartum period with this population to be a significant clinical success and worthy of pursuing to develop a commercially viable product to assist postpartum and potentially pregnant women in obtaining the sleep they need and deserve to better care for the needs of their infant.”
