Introduction:
Sleep is an integral element of health that impacts physical, mental health and well-being. Ensuring sufficient sound sleep is, therefore, critical for maintaining and nourishing one's health. Both the quantitative and qualitative attributes of sleep matter for one's health. Any discrepancies or irregularities in sleep could translate into several health conditions and ailments. Disrupted sleep hampers various biological processes and bodily activities.
What Is Insomnia?
Insomnia is a routinely reported state where one may encounter trouble sleeping. The inability to sleep peacefully and uninterruptedly, even after trying hard for hours at night, is a critical medical scenario that mandates medical assistance. It is a distressing and bothersome medical state where one longs for sleep but cannot attain it. It could be presented as interrupted sleep, where one often wakes up amidst sleep and remains awake for longer. Insomnia hampers and downturns one quality of life. It could deteriorate their productivity by making them inactive and sleepy all day.
The human body has a definite and discrete sleep-wake cycle, otherwise called the circadian rhythm, which keeps one awake and alert during the daytime, typically lasting for 16 hours, while rendering sleepiness during the nighttime, lasting eight hours. The sleep-wake cycle awakens one in the morning. It puts them into sleepiness at night, ensuring that the body sleeps sufficiently and soundly, leaving it fresh and energetic throughout the day. The sleep-wake cycle also modulates and balances the workload over several vital organs like kidneys.
Circadian rhythm disorder is the umbrella term for any disruption or derangement in the sleep-wake cycle. Insomnia is perceived as one of these disorders. Insomnia necessitates prompt medical attention to restore the sleep-wake cycle. In the absence of medical therapy, insomnia could hamper several vital functions, instigating other systemic illnesses and ailments.
Can Lack of Sleep Cause Kidney Problems?
Insomnia could bring out several alarming comorbidities. Earlier, several mental disorders like anxiety, stress, and depression were perceived to be triggered by insomnia in the long run. However, later, with advancements in research and studies, several study reports came out that underscored the propensity for kidney diseases in insomnia patients. Insomnia could invoke kidney diseases and could even deteriorate the recovery and survival prospects. The exact mechanism by which insomnia gravitates toward kidney disease is not yet thoroughly appreciated or pinned down. However, several hypotheses are put forward to elaborate on and underscore how insomnia and kidney disease share a definite connection or association.
How Does Insomnia Raise the Risk of Kidney Disease and Death?
-
Mitigated Melatonin Proportions: Qualitatively and quantitatively, insufficient sleep could deteriorate and hamper kidney functions and cellular activities. With insomnia, the kidney's functional attributes decline and palliate. It is mainly invoked by disruptions and derangements in certain hormonal liberations and functions. Melatonin is one such bodily hormone (a chemical messenger that can act at specific target points) liberated by the pineal gland. It largely pilots the sleep-wake cycle and elicits protective shielding over the kidney functions. Melatonin safeguards the functional attributes of the kidneys and augments their functionalities.
-
Enhanced Cortisol Liberation: Insomnia could upscale the stress hormone (cortisol) level. Overstated cortisol proportions could, in turn, gear up the blood pressure. Enhanced blood pressure (hypertension) could directly harm the kidney cells and deteriorate and palliate their cellular functions. This eventually gives rise to kidney diseases. Chronic kidney disease (CKD) is one such kidney problem that chronic insomnia could bring forth. In chronic kidney disease, the kidney’s functional depletion progresses gradually and steadily and is often inflicted by harm to the kidney cells over an extended period. Hypertension invoked by insomnia is, therefore, another triggering factor that could choke the kidney’s blood flow and impair its functions. As CKD progresses into advanced stages, it could further palliate and downturn melatonin liberation, which worsens and aggravates sleeplessness or insomnia.
-
Through Oxidative Stress: Insomnia augments and upturns the generation of free radicals, reactive oxygen entities that could invoke harm to cells through a process called oxidative stress. Through reactive oxidative stress, insomnia brings out harm and dysfunction in the kidney cells. Free radical-mediated harm to kidney cells is another critical integrant that could pave the way for kidney diseases.
-
Deranged Glucose Metabolism: Insomnia can also invoke errors and discrepancies in various metabolic processes, which could bring out metabolic issues and associated ailments. Insomnia could derange glucose metabolism and pull off an escalation in blood sugar proportions. Diabetes (inflicted by overstated blood sugar proportion) is one such ailment that is instigated by disruptions in glucose metabolism.
Apart from enhancing the inclination for kidney disease, insomnia also inflames and augments the risk of death. Several studies have deeply explored and figured out that CKD with insomnia could pose an appreciable threat to one’s life than CKD alone. Insomnia-invoked kidney disease elicits a stronger and greater potential to endanger life.
Which Kidney Diseases Could Insomnia Bring Out?
Below are a few of the kidney diseases that insomnia could bring forth:
-
Chronic kidney disease.
-
Glomerulonephritis (kidney disease that is invoked by harm to the kidney's blood filtering unit called glomerulus).
-
Hypertensive nephrosclerosis (kidney harm inflicted by overstated blood pressure over a longer period).
-
Diabetic nephropathy (kidney harm inflicted by long-standing diabetes).
Conclusion:
Insomnia is a commonly encountered sleep disorder that has the potential to invoke other health crises. Insomnia could raise the risk of kidney disease and death when left with no medical intervention over a prolonged period. This underscores the relevance of adequate sleep in maintaining one’s health and wellness. In case one encounters trouble sleeping or sleeplessness, get medical guidance so the factor that prompted insomnia can be addressed and strategies can be adopted to combat it.
The alliance between melatonin and CKD is bidirectional, so CKD and insomnia worsen. Hemodialysis (waste and toxins from the blood are removed and eliminated with machinery support) and kidney transplantation (seeding and grafting the donor’s kidney to substitute the nonfunctional kidney of the patient) are advocated for malfunctioning or non-functioning kidneys. Treatment of insomnia in CKD calls for a multidisciplinary approach where both CKD and insomnia need to be tackled to derive and pull out the best treatment outcome and thereby mitigate the mortality rate.
