Cortex-wide variation of neuronal cellular energy levels depending on the sleep-wake states

The brain is assumed to exert homeostatic functions to always keep the cellular energy status constant, this has not been proven. Researchers discovered that cortical neuronal intracellular concentrations of ATP, the major cellular energy metabolite, greatly decreased during REM sleep, despite a simultaneous increase in cerebral hemodynamics for energy supply, compared with waking in mice. These indicate that cerebral energy metabolism may not always meet neuronal energy demands. Source

Weighted blankets can decrease insomnia severity

Weighted blankets are a safe and effective intervention in the treatment of insomnia, according to researchers who found that insomnia patients with psychiatric disorders experienced reduced insomnia severity, improved sleep and less daytime sleepiness when sleeping with a weighted chain blanket.
