Only about one-third of respondents were getting enough sleep (1). What people may not be aware of is that not clocking enough hours each night might be putting your health at risk. A recent study published in the Journal of Clinical Endocrinology and Metabolism showed that even a partial night’s rest over a single night induces insulin resistance (2). Nine healthy individuals were studied after a night of normal sleep (up to 8.5 hours) and a night of partial sleep (4 hours duration). In those with only 4 hours of sleep there was a significant decline in glucose disposal suggesting decreased insulin sensitivity (2). Insulin is a key hormone involved in blood glucose control. When insulin is secreted by the pancreas, it allows for glucose to be drawn into your cells to be used for energy. If insulin resistance is present, cells don’t respond to this hormone, so more insulin is needed in order for glucose to get into your cells. It’s when the levels of insulin and glucose build up in the body that it puts individuals at greater risk for disease, especially type II diabetes and heart disease (3). Time to get those Zzzzzzzzzzzzzzzz’s!
