Hypothesis
Does the atonia in REM sleep provide a utility to help restore the mechanobiology and respective diurnal intervertebral disc hydraulic loss?
Conclusion
The study suggests that REM sleep atonia may help in the recovery of intervertebral disc height and hydration.
Supporting Evidence
- REM sleep atonia may allow for better hydration of intervertebral discs.
- Humans lose height during the day due to intervertebral disc compression.
- Infants experience more REM sleep, which may aid in their growth and development.
Takeaway
When we sleep, our muscles relax, which might help our spine recover from the day's wear and tear.
Methodology
The article discusses using polysomnography and recumbent MRI to study intervertebral disc changes during REM sleep.
Limitations
The relationship between REM sleep atonia and intervertebral disc recovery has not been thoroughly investigated.
