The latest research has found that when we enter deep sleep, deep sleep brain waves (especially sleep spindles and slow waves) activate the body's parasympathetic nerves, relax the body and mind, and increase the body's insulin sensitivity, prompting cells to absorb more sugar, improving blood sugar control the next day, and helping to maintain blood sugar stability.
In different sleep stages, our hormones will change in different concentrations: when entering deep sleep (that is, the slow-wave sleep period), it is an important stage for the repair of body functions, including the repair of blood sugar regulation function. During this stage, the concentration of adrenaline will decrease. On the contrary, when the quality of sleep is reduced or sleep disorders such as insomnia or sleep apnea occur, the sympathetic nerves will be stimulated and the secretion of adrenaline will be increased, resulting in poor glucose tolerance and increased insulin resistance, leading to an increase in blood sugar.
To put it simply, if you don’t sleep well and have an unbalanced diet, your blood sugar may remain at a high level and increase your risk of type 2 diabetes. The good news is that we can help stabilize blood sugar and prevent diabetes by improving the quality and quantity of sleep, coupled with proper diet and exercise!
