Proper sleep is of great essence for the health of the human body as it is almost the same as breathing, digestion or immunity. It is of vital importance for immune development, brain maturation, body growth, hormonal stimulation, cell reconstruction, and as well as for cognitive functions and mood.
Sleep deficiency which includes less than 6 hours of sleep per night can substantially affect the overall health and elevates the risk of the occurrence of many ailments.
Lack of sleep can cause the following diseases:
Cardiovascular illnesses like stroke, myocardial infarction, and angina pectoris can be as well as triggered by sleep deficiency. As per a 2017 study by Qiao He and Peng Zhang of China Medical University (Shenyang, China), shortage of sleep and insomnia are strongly related to the increased risk of cardiovascular diseases. The results of this study were obtained via a meta-analysis of scientific data from previously conducted studies. Namely, the researchers discovered that in people having issues with falling asleep the risk of a cardiovascular event is increased by 27%, if the sleep is not restorative, then the risk is increased by 18% and by 11% when there are various complications of sleep. Have in mind that there was no connection with early waking up and an occurrence of a cardiovascular disease.
Obesity and diabetes
Sleep deprivation can increase the free fatty acids in the body and affect the rate of the metabolism and the ability of insulin to regulate blood sugar as per a scientific study performed by Josiane Broussard of the Diabetes and Obesity Research Institute of the Cedars-Sinai Medical Center in Los Angeles, USA. Researchers from the Department of Medicine at the University of Chicago and At the University of Wisconsin (USA) have also confirmed this fact. People who lack sleep are at higher risk of obesity and diabetes or if they are already suffering from them sleep deprivation will worsen their conditions.
Health conditions like inflammatory bowel disease (IBD) or ulcerative colitis and Crohn’s disease can develop due to sleep shortage. As per a conducted study by Ashwin Ananthakishnan and Hamed Khalili, Department of Gastroenterology, Massachusetts General Hospital (US) sleep deprivation can trigger inflammatory reactions that can lead to the occurrence of these two diseases,
Sleep deprivation affects millions of people, namely in France 54% of the population have sleeping issues as per a conducted survey by the French National Institute of Sleep and Vigilance (INSV). This sleeping disorder is closely related to a higher risk of developing and precipitating the signs of Alzheimer’s disease.
This was further on analyzed in a study by Adam Spira of the Mental Health Department of the Johns Hopkins Bloomberg School of Public Health (USA) and Alyssa Gamaldo of the National Institutes of Health (USA). People suffering from Alzheimer have elevated levels of beta-amyloid protein which is accountable for memory loss and lack of communication between neurons. In this study were involved 70 participants in the age range of 53 to 91 years old, and those people who did not have proper sleep had an increase in beta-amyloid protein. Conclusively, we can state that sleep deprivation can cause and speedup the Alzheimer’s disease.
Sleep greatly influences the function of the body and a person’s mood, and as per latest research sleeping disorders are related to a high risk of suicide. In fact, one of the main risk factors for suicidal behavior is sleep, particularly in the older population.
In a comprehensive study which involved 14,456 adult participants over 65 years old in a period of 10 years lack of sleep increased the risk of suicide, no matter of the existence of depressive disorders. This study was carried out by Rebecca Bernert, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine (California, USA) and Carolyn Turvey, Department of Psychiatry, University of Iowa Psychiatry (United States).
In order to prevent suicidal behaviors elderly should have a proper night sleep.
