The morning blood stress surge in each instances had been in contrast.
“Though the outcomes from this pilot should be interpreted with warning and validated in a bigger pattern, her analysis confirmed that those that had been compelled awake had a morning blood stress surge that was 74% larger than those that awoke naturally — proof of a hyperlink between brief sleep period, compelled awakening and morning blood stress surge,” Kim mentioned in a information launch.
