Sleep health: Understanding fatigue, dehydration, and hypnic jerks

sleep hygiene hypnic jerks sleep apnea nocturnal dehydration sleep quality

Common sleep-related phenomena and their underlying causes are being highlighted by health experts. Persistent fatigue may not be caused by a lack of sleep duration, but rather by poor sleep quality. Potential causes include sleep apnea—characterized by snoring and gasping for air—iron deficiency, or hypothyroidism. Additionally, certain medications like antihistamines and antidepressants can contribute to daytime sleepiness.

Morning thirst and dry mouth are often the result of natural fluid loss during the night. The body loses between 0.5 and 1 liter of fluid through respiration and skin evaporation while sleeping. Factors such as mouth breathing, warm room temperatures, and alcohol consumption can exacerbate this nocturnal dehydration.

Many people also experience hypnic jerks, which are involuntary muscle twitches occurring during the transition from wakefulness to sleep. Often felt as a sensation of falling, these jerks are considered harmless and are experienced by approximately 70 percent of the population. They may occur more frequently due to stress, caffeine, or extreme fatigue.
