Although until now researchers have not been able to definitively state that lack of sleep directly causes type 2 diabetes, recent studies have shown further evidence that lack of sleep is associated with serious health complications. Even if someone maintains a healthy diet, the risk of developing type 2 diabetes may still be high if lack of sleep remains a habit. Unfortunately, the importance of sleep is often overlooked by many people, even though good sleep patterns also play a significant role in maintaining health.

Diabetes type 2 is a chronic condition that occurs when the body cannot produce enough insulin hormone or cannot use insulin effectively. Insulin plays a role in regulating the movement of blood sugar into the body's cells to produce energy. Insufficient insulin can cause an increase in blood sugar levels, which can eventually lead to type 2 diabetes over time.

A study was conducted involving 247,000 individuals collected between 2006 and 2010 for the UK Biobank, a comprehensive biomedical database. The study aimed to investigate the relationship between poor sleep quality, dietary patterns, and the development of type 2 diabetes. The results found no association between a healthy eating pattern and a decrease in the risk of type 2 diabetes in participants who slept less than six hours per day. These findings emphasize that maintaining health involves more than just diet and exercise. Sleep, healthy eating patterns, and exercise together form an important foundation for body health and fitness.

Apart from type 2 diabetes, lack of sleep quality can also result in daytime functional disturbances that potentially decrease academic performance, cause conflicts and errors in the workplace, or present difficulties in mental health. Various diseases such as cardiovascular disease, diabetes, obesity, and central nervous system disorders have been associated with lack of sleep quality.

In this world, only about 1 to 2% of the population is genetically capable of functioning with less sleep. On the contrary, every person requires an adequate amount of sleep every day. Considering the importance of sleep for overall health, it is highly recommended for every individual to establish and adhere to their own healthy sleep routine.
