Lack of sleep can have serious consequences on our health. It has been associated with increased risk of various complications, highlighting the significance of addressing sleep deprivation for overall well-being. 

According to Centers for Disease Control and Prevention (CDC, 2020), if you consistently sleep for less than 7 hours per night, it will become more difficult to control your diabetes. Insufficient sleep can cause the following problems:
  • increase insulin resistance, making it harder for your body to regulate blood sugar levels.
  • increase your appetite and reduce the feeling of fullness after meals, leading to overeating. It can make you more inclined to choose unhealthy, high-carbohydrate, and sugary foods.
  • It can hinder weight loss efforts by making it more challenging to shed excess pounds.
  • It can raise blood pressure and significantly increase the risk of a heart attack.
  • It can weaken your immune system, making it less effective at fighting off infections.
  • It can also increase the likelihood of experiencing depression and anxiety. (CDC, 2020).
