Sleep Deprivation and Insulin Sensitivity
Average sleep levels have dropped
Average sleep in the USA has dropped from 9 hours a night to less than 7 hours per night over the last 100 years: so much for having more leisure time!
This could have an impact on health in the long term as recent research has shown that short term sleep deprivation leads to an inability to regulate insulin as well as people who have a good night’s sleep.
Healthy subjects were restricted to 5 hours sleep a night for a week and glucose tolerance levels were measured throughout the study. Glucose metabolism was impaired as a result of this sleep deprivation (1). This is a factor in early onset of Diabetes.
This is an important finding because it shows that general lifestyle factors have a bearing on overall health and resistance to disease.
Previous studies have also shown that sleep deprivation leads to an increased appetite for carbohydrates, increased blood pressure and increased risk of cardiovascular disease.
Knowing the importance of having a good night’s sleep is one thing, getting it is another. Think about how much you are having, and whether you can have more.

Josh Steels: wheelchair tennis
I started working with James 3 years ago via the TASS programme. When James first met me, physically I was nowhere the best I could be. Since working with James I have seen vast improvements in my fitness and strength which has been put into great use on court. Each session is worked around making sure I am able to get the best quality training as well as catering for my chronic pain and fatigue levels. On top of this James has always been happy to meet at facilities that are best for myself meaning I could fit training sessions in on route to tournaments or camps.
