Sleeping with the light on at night may seem harmless, but it can actually put your health at risk. Studies have shown that exposure to artificial light at night can disrupt the body’s glucose and cardiovascular regulation, leading to an increased risk of heart disease and diabetes.
The Feinberg School of Medicine conducted a study that found that even one night of sleeping in normal light can lead to disturbances in glucose and cardiovascular regulation, which can become risk factors for diabetes and other metabolic syndromes. The study found that artificial light activates the sympathetic arm and the immune nervous system, which are responsible for fighting external attacks in the body. When these systems are activated, sleep is affected and cardiovascular function is impaired. This can lead to an increased risk of chronic diseases in the body.
Research on obese women found that those who slept with the TV or lights on had a higher risk of obesity than those who slept with the lights off. Another study found that people who slept with lights on at night had increased insulin resistance when examined in the morning. This means that the use of blood glucose to give energy to the body is reduced, or it cannot be used at all. To deal with this situation, the pancreas has to make more insulin, which can lead to an increase in blood sugar levels over time.
In conclusion, it is important to be aware of the potential risks associated with sleeping with the light on at night. To promote a healthy sleep environment, it is recommended to sleep in complete darkness, as this can help to regulate the body’s glucose and cardiovascular regulation, as well as reduce the risk of chronic diseases. Additionally, it is important to note that this habit also have an effect on the mental health, it could lead to insomnia, anxiety, and depression.
