Sleep – not too little, not too much, just the right amount

By Rich Jackson

What are the factors behind the recent increases in the incidence of type 2 diabetes? We know that genes are the underlying cause for determining who is susceptible to developing diabetes and who isn’t, and we know that our genes have not undergone much change in the last 50 years. This tells us that changes in our environment and the way we live are the main forces driving the increase in diabetes. When we think of these environmental and lifestyle changes our thoughts often go to food and activity. We know, however, that chronic stress is a factor, and also pollution. This article released today looked at a group of genes associated with weight gain and diabetes, and found that the effects of these genes on obesity was much stronger in people who had either too little sleep, or who had too much sleep. This fits with a lot of other research findings showing that disrupted sleep, too little sleep or even too much sleep can change your metabolism and appetite. The data is pretty consistent, telling us that 7 – 8 hours of sleep is probably the sweet spot.
