DIABETES AND SLEEP: CLOSELY LINKED

There is a correlation between sleep and diabetes through sleep disorders such as insomnia, hypersomnia syndrome, restless legs, or disorders apnea syndrome ... can be the effects of diabetes or have effects on him. Poor sleep hangs over glycemic control increases the risk of developing diabetes and may aggravate existing diabetes.

The vital function of sleep
Sleep is vital for the body. It is necessary for recovery from physical, intellectual and psychological. Among other functions, sleep contributes:

  • mechanisms of cognition and memory
  • the elimination of toxins
  • to replenish energy reserves of nerve and muscle cells
  • and especially the regulation of metabolic functions (glucose, appetite ...) which explains its link with diabetes.


Circadian rhythms
Each person has biological rhythms that regulate the activity of our body. Among these rhythms, circadian rhythms characterize our lifestyle over 24 hours with alternating phase of sleep at night and sleep during the day. This internal clock is part of our biological heritage and may vary slightly from one individual to another. However, it is synchronized by the main time markers that are daylight and social activity. Despite this, some people tend to get up later or earlier. But one thing is for sure, these rhythms are essential to the balance of the body and repeated disturbances (sleep disorders, night work, work day with no light, staggered schedules ...) have an impact on health .
Major sleep disorders
Sleep well, regularly 8h per night on average , is needed by the body and makes a good recovery. If some need 9h 6h and others only to feel like (large and small sleepers), a sleep time beyond or below 10h 5h is a warning signal and can hide a sleep disorder .

Major sleep disorders are:

  • insomnia (sleep too short): difficulty falling asleep, poor sleep, multiple awakenings during the night or early morning
  • hypersomnia (sleeping too long): regular sleep or catch up (on weekends, holidays ...), daytime somnolence (excessive tendency to fall asleep in situations of everyday life)
  • Restless legs syndrome : discomfort in the legs that require stand
  • Obstructive sleep apnea syndrome : repeated cessation of breathing during sleep


Links between sleep and diabetes

Effects of sleep on diabetes

Sleep disorders can have an effect on diabetes, overweight and obesity. Studies show that reduced sleep causes a dysregulation of glucose metabolism (50% decrease in the action of insulin, 30% reduction of the amount of insulin produced), tennis favor the onset of diabetes or the exacerbation of existing diabetes.

During sleep, fat cells secrete a hormone (leptin) that goes to sleep feeling hungry. The day the stomach, he secretes another hormone (ghrelin) that facilitates food intake. The decrease in sleep time cause people to eat more, which increases the risk of obesity.

Effects of diabetes on sleep
Diabetes can be a cause of impaired sleep. Some insomnia are indeed related to impaired glycemic control (especially in case of hypoglycemia at night , common in type 1 diabetes). Rapid changes in glucose levels during the night causing nighttime awakenings , insomnia factors.

People with diabetes are also bigger consumers of sleeping pills and hypnotics .

Some complications of diabetes such as frequent urination (polyuria), musculoskeletal pain (which require to get up several times at night) may also be the cause of insomnia . The restless legs can result from nerve damage (neuropathy) associated with diabetes. The diabetic retinopathy can she, impair the vision of light and push the diabetic person underexposure with an effect on circadian rhythms .

Food and sleep
Some foods are more challenging and promote wakefulness such as proteins, while others promote sleep like carbohydrates. We therefore avoid eating meat in large quantities in the evening, but we allow a dessert or a sweet drink (tea, for example) that promotes sleep and prevents hungry at bedtime. diabetes and sleep are interrelated . No wonder they share the same lifestyle and dietary measures: limit alcohol, eat healthy, regular physical activity ... By improving one, it helps balance the other and vice versa .
