Among the factors contributing to the high prevalence of type 2 diabetes, obesity, decreased activity, and excessive calorie intake are clear causative factors. Many patients have a significant increase in blood glucose 2 hours after a meal, which is related to the patient’s postprandial inactivity. If after breakfast and dinner, the blood glucose increase is not obvious, only after lunch blood glucose increase is obvious, to consider whether it is related to napping habits. If you sleep immediately after a meal, it slows down the metabolism of blood glucose in the body and the utilization of energy is relatively slow. Therefore, it is recommended to move around for 1 hour after a meal and then take a nap, which may be better for blood glucose control. Those who have the habit of napping, the calorie consumption is certainly less than those who do not nap, the catabolism is low, the result is of course the blood glucose and lipid levels to be higher, and the human body’s self-balancing and self-regulation mechanism has something to do with.
