Next week (or next month, depending on how this week goes), make another 30-minute change. This week, try going to bed 30 minutes earlier every night and waking up 30 minutes earlier every morning.

If you don't think you can do it (but want to), start with slow, incremental changes in your sleep cycle. In addition to using less fat for energy than early birds (and favoring carbohydrates over fat), night owls also were more insulin resistant – a risk factor for both type 2 diabetes and cardiovascular disease.Īre you an early bird or a night owl? If you're a night owl, consider becoming an early bird (or at least and earlier bird) for the reasons this study suggest.

They also had participants performed aerobic fitness tests to assess energy use. In arriving at their findings, researchers evaluated adults from each sleep-wake cycle who ate the same calorie- and nutrition-controlled diet, and fasted overnight, for one week. Research published in Experimental Physiology suggests differences in the wake-sleep cycles between early birds and night owls affect metabolism and energy storage early birds have a greater tendency to use fat as energy, both at rest and during exercise. In this weekly series, LiveScience examines the psychology and sociology of opposite human behaviors and personality types. Specifically, night owls are more likely to suffer from one or both conditions compared to early birds. For an early bird type, a 9 pm bedtime may be the norm, and rising at 5 am without an alarm clock feels relatively effortless. Your sleeping pattern affects your risk of developing two major health issues: type 2 diabetes and heart disease. Early birds, or those who tend to wake early and go to bed early, are people who naturally feel sleepy earlier in the evening and naturally wake early in the morning.
