Sleep Disorders: When Poor Sleep Becomes a Medical Problem

Everyone has a bad night of sleep occasionally. But when "occasionally" becomes "most nights," and when poor sleep starts affecting how you function during the day, something has shifted from a nuisance to a medical problem.

Sleep disorders are remarkably common and remarkably undertreated. About 70 million Americans have a chronic sleep disorder, and many never seek treatment — either because they've normalized poor sleep or because they don't realize effective treatments exist beyond sleeping pills.

When Poor Sleep Is More Than a Bad Habit

There's a difference between poor sleep hygiene (scrolling your phone until midnight, then wondering why you can't fall asleep) and a sleep disorder. Here's how to tell:

It might be a sleep disorder if:

• You can't fall asleep within 30 minutes despite being tired and having a reasonable bedtime routine — consistently, not just occasionally
• You wake up multiple times during the night and can't get back to sleep
• You wake up hours before your alarm and lie there unable to return to sleep
• You sleep 7-8 hours but wake feeling unrefreshed, as if you didn't sleep at all
• You're excessively sleepy during the day despite what should be adequate sleep time
• Your bed partner reports loud snoring, gasping, or pauses in your breathing
• You have restless, uncomfortable sensations in your legs that worsen at night

It's probably a habit issue if:

• Your sleep improves dramatically on vacation or when stressors resolve
• You're simply not giving yourself enough time to sleep (in bed for 5-6 hours and wondering why you're tired)
• Screen time, caffeine, or alcohol use is clearly driving the problem

Many people have elements of both — a sleep disorder made worse by poor habits. Addressing both is ideal.

Common Sleep Disorders

Insomnia

The most common sleep disorder. Insomnia is defined as difficulty falling asleep, staying asleep, or waking too early, along with daytime impairment, occurring at least three nights per week for at least three months (for chronic insomnia).

Insomnia frequently coexists with other conditions — anxiety, depression, chronic pain, menopause, and medications can all drive or worsen insomnia. Treating the underlying condition often helps, but sometimes insomnia becomes self-sustaining even after the trigger is addressed.

Obstructive Sleep Apnea

More common than most people realize, especially in Florida's older population. Sleep apnea causes repeated partial or complete airway collapse during sleep, leading to drops in oxygen, fragmented sleep, and cardiovascular stress.

Classic signs: loud snoring, witnessed breathing pauses, gasping or choking during sleep, morning headaches, excessive daytime sleepiness, and difficulty concentrating.

Risk factors include obesity, male sex, age over 50, large neck circumference, and craniofacial anatomy. But thin, young women can have sleep apnea too — it's underdiagnosed in populations that don't fit the stereotype.

Sleep apnea requires a sleep study for diagnosis (now often done at home rather than in a sleep lab) and is typically treated with CPAP, oral appliances, or in some cases surgery or weight loss.

Restless Legs Syndrome

An uncomfortable urge to move the legs, typically worse in the evening and at rest. It can make falling asleep extremely difficult. RLS is often associated with iron deficiency, kidney disease, neuropathy, and pregnancy. Treatment depends on the underlying cause but may include iron supplementation, dopaminergic medications, or gabapentin.

Circadian Rhythm Disorders

Your internal clock is misaligned with your desired sleep schedule. Common in shift workers, people with irregular schedules, and some individuals whose natural rhythm skews very early (advanced sleep phase) or very late (delayed sleep phase). Treatment involves strategic light exposure, melatonin timing, and schedule adjustments.

Treatment Options That Actually Work

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is the first-line treatment for chronic insomnia — recommended before medication by every major sleep medicine guideline. It's more effective than sleeping pills for long-term insomnia management, and the results persist after treatment ends (unlike medication, which only works while you take it).

CBT-I typically involves:

• Sleep restriction — counterintuitively, spending less time in bed to increase sleep drive and consolidate sleep
• Stimulus control — rebuilding the association between bed and sleep (not bed and anxiety about sleep)
• Cognitive restructuring — addressing the anxious thoughts about sleep that perpetuate insomnia
• Sleep hygiene optimization — the behavioral basics
• Relaxation training — specific techniques to reduce physiological arousal at bedtime

CBT-I can be delivered in person, via telehealth, or through structured digital programs. It typically takes 4-8 sessions.

Medication Options

When medication is appropriate — either while CBT-I is taking effect or for insomnia that doesn't fully respond to behavioral treatment — several options exist:

Melatonin and melatonin agonists: Melatonin is most useful for circadian rhythm issues (jet lag, shift work, delayed sleep phase) rather than general insomnia. Low doses (0.5-3 mg) taken 1-2 hours before desired bedtime work better than the high doses (10+ mg) many people take. Ramelteon is a prescription melatonin receptor agonist with a more consistent effect.

Trazodone: An older antidepressant commonly used at low doses for sleep. It's not habit-forming and can be helpful for sleep maintenance. Side effects can include morning grogginess and, rarely, priapism in men.

Gabapentin: Useful when insomnia coexists with pain, anxiety, or restless legs. Promotes deeper sleep stages.

Hydroxyzine: An antihistamine with anti-anxiety properties. Can help with sleep-onset insomnia, especially when anxiety is a component. No dependence risk.

Prescription sleep medications (zolpidem, eszopiclone, suvorexant): These are effective but are generally best used short-term or intermittently. Zolpidem (Ambien) in particular carries risks of complex sleep behaviors and next-day impairment. Suvorexant (Belsomra) and lemborexant (Dayvigo), the orexin receptor antagonists, represent a newer approach with a different mechanism and may be appropriate for some patients.

Benzodiazepines: Generally avoided for chronic insomnia due to dependence risk, tolerance, and negative effects on sleep architecture. They may suppress deep sleep and REM sleep, meaning you sleep but the quality is reduced.

What About Over-the-Counter Options?

Diphenhydramine (Benadryl) and doxylamine (Unisom): Common OTC sleep aids. They work short-term but shouldn't be used regularly. They cause next-day drowsiness, cognitive impairment, and are on the Beers list of medications to avoid in older adults due to anticholinergic effects.

Magnesium: Some evidence for mild sleep benefit, particularly magnesium glycinate. Generally well-tolerated and worth trying, but unlikely to resolve significant insomnia on its own.

CBD: Evidence is limited and inconsistent for sleep. Some people find it helpful; the research hasn't caught up to the marketing.

Florida-Specific Sleep Considerations

Florida presents some unique sleep challenges:

• Heat and humidity: Even with air conditioning, Florida's climate can affect sleep quality. Bedroom temperature between 65-68 degrees Fahrenheit is optimal for sleep.
• Seasonal population shifts: Snowbirds and seasonal residents face circadian disruption from travel and schedule changes.
• Hurricane season: The anxiety and disruption of storm preparation and aftermath significantly impacts sleep for many Floridians.
• Shift work: Florida's tourism, healthcare, and service industries employ large numbers of shift workers, a population particularly vulnerable to sleep disorders.
• Aging population: Sleep architecture changes with age, and Florida's older demographic means a higher prevalence of sleep disorders including sleep apnea and insomnia.

When to Talk to a Provider

If poor sleep is affecting your daytime function — your concentration, mood, energy, work performance, or safety — for more than a few weeks, it's time to address it. If your bed partner reports significant snoring or breathing pauses, sleep apnea should be evaluated regardless of how you feel.

Sleep is not a luxury. It's a biological necessity that affects virtually every aspect of health — immune function, cardiovascular health, weight management, mental health, pain perception, and cognitive performance. Treating sleep disorders is treating your overall health.
