Does Sleeping with Lights On Make You Diabetic?

Over 30 million people worldwide have diabetes and it is the sixth leading cause of death. Diabetes type 2, the most common type, is a chronic condition brought on by insulin resistance. Insulin aids in the movement of blood glucose to cells such as the liver, muscles, fat, and other tissues to be used as fuel. When the body struggles to produce insulin or when the insulin itself is unable to transfer glucose into these cells effectively, insulin resistance develops. As a result, there is an accumulation of glucose in the blood, often known as high blood sugar, which is a defining sign of diabetes. If not handled correctly, this could have adverse effects.

People have grown accustomed to sleeping with light, from street lights outside their bedrooms or from the inside lamps and gadgets. That might not be a great idea. Researchers have found that sleeping in a room with moderate lighting instead of a dimmer light may impact metabolic and cardiovascular health. Even minimal light can adversely affect one’s health when sleeping.

Research suggests that older persons may be at an increased risk for obesity, diabetes, and high blood pressure if they are exposed to light while sleeping. Studies reveals that older persons are more likely to develop obesity, diabetes, and hypertension when sleeping with exposure to any form of light, even low light.

Several researches have shown that when exposed to more light while sleeping, the body enters an awake state which increases heart rate increases not allowing the body to have a good night’s sleep. There is strong evidence that poor sleep is associated with ill health and that light in the bedroom at night is detrimental to sleep and these effects are more pronounced in older people. A complex relationship exists between diabetes and sleep as type 2 diabetics have trouble falling or staying asleep.

After patients slept in a bright room, investigators discovered insulin resistance had developed the following morning. Insulin resistance happens when your muscles, fat, and liver cells don’t respond to insulin well and can’t use the blood’s glucose for energy. For each unit lost of insulin, your pancreas produces more. Your blood sugar level rises with time.

Circadian rhythms are the natural cycles of light and darkness-related changes in the body and mind. Hormone secretion, body temperature, and sleep-wake processes are all regulated by circadian rhythms. Circadian rhythms impact the hormone melatonin, which is in charge of promoting restful sleep. Therefore, when circadian rhythms are off, melatonin production is off, affecting regular sleep cycles. A good night’s sleep is crucial for preventing the onset of diabetes. Studies show that changing and inconsistent sleep habits may increase the risk of type 2 diabetes.

Overexposure to artificial light over time has been linked to a range of illnesses, including type 2 diabetes. Even after accounting for weight, OSA (Obstructive Sleep Apnea) still seems to impact glucose regulation and insulin resistance. Sleep fragmentation brought on by OSA disrupts slow-wave sleep, and the body’s oxygen supply is occasionally cut off. In combination, these outcomes result in decreased glucose metabolism and increased insulin resistance. Numerous studies have shown that short-term sleep apnea therapy lowers blood sugar levels.
