Creating Waves of Awareness
Dawn news reported
"Researchers in the Netherlands and UK compared the white blood cell counts of 15 healthy young men under normal and severely sleep-deprived conditions.
The greatest changes were seen in the white blood cells known as granulocytes, which showed a loss of day-night rhythm city, along with increased numbers, particularly at night.
“The granulocytes reacted immediately to the physical stress of sleep loss and directly mirrored the body s stress response,” said Katrin Ackermann, postdoctoral researcher at the Eramus MC University Medical Centre Rotterdam, the Netherlands.
“Future research will reveal the molecular mechanisms behind this immediate stress response and elucidate its role in the development of diseases associated with chronic sleep loss,” said Ackermann, who led the study, according to an Eramus statement.
Previous studies have linked sleep restriction and sleep deprivation with the development of obesity, diabetes and hypertension.
Others have shown that sleep helps sustain the functioning of the immune system, and that chronic sleep loss is a risk factor for immune system impairment"
Do you feel 15 subjects is sufficient to make a broad claim?
I think that such a small number may not be enough,but it is my personal experience that if i have a disturbed sleep and you have to get up a few times in night,it effects mood,makes me edgy.my BP goes slightly up,and my energy level is definitely low.
It seems it all starts with increased white cells in our blood stream. We hope other comments will also help us all to understand the importance of good sleep.
