This blog post is a quick response to the recent discussion conducted by Professor of Medicine and Chief of Gastroenterology at Eastern Virginia Medical School, Dr. David Johnson, in which he talks about the many effects that sleep deprivation can have on your health and wellbeing.
The Professor states that sleep deprivation has a profound effect on several disease states including stroke, obesity, diabetes and memory loss. Epidemiologic studies suggest that less than 6 hours of sleep a night increases the risk of stroke by 4 times, obesity risk increases due to an associated increase in ghrelin, reducing satiety and increasing hunger, and diabetes risk increases because of increases in insulin resistance.
He also alludes to the effects sleep deprivation can have on Osteoporosis, he notes that bone mineral density is lower in sleep deprived animals with changes in bone marrow also evident within 3 months of sleep deprivation. He also states there is a 48% increase in early cardiac death and an overall 4 fold increase in general mortality!
If you’re not getting enough sleep, particularly when training, then these reasons should be good enough justification to adjust that sleeping routine!
