Sleep Disturbance: Causes, Risks, and Management

When dealing with sleep disturbance, a disruption in normal sleep patterns that can affect mood, energy, and overall health. Also known as insomnia, it often shows up alongside other health issues like anxiety, medication side effects, or chronic illness. Sleep disturbance isn’t just feeling tired; it’s a signal that something in the body’s balance is off.

One big player is corticosteroids, anti‑inflammatory drugs such as dexamethasone that are used for COPD, asthma, and autoimmune conditions. These drugs can raise cortisol levels, which in turn stimulate the brain’s alert center, making it harder to wind down at night. A similar effect comes from antihistamines, medications like Claritin or Allegra that block histamine to relieve allergies. While some antihistamines are labeled “non‑drowsy,” others still cross the blood‑brain barrier and can either cause excessive sleepiness or, paradoxically, disrupt the normal sleep cycle.

Beyond drugs, mental health conditions play a major role. Stress, depression, and anxiety can all trigger a feedback loop: racing thoughts keep you awake, and lack of sleep worsens mood symptoms. Research on brain ischemia shows that reduced blood flow can impair mood regulation, leading to both depression and fragmented sleep. Lifestyle factors such as dehydration also matter; insufficient fluids can irritate the throat and sinuses, prompting frequent awakenings, while proper hydration supports the body’s natural sleep‑wake rhythm.
