Most snoring improves with simple changes like losing weight, sleeping on your side, avoiding alcohol and sedatives at night, clearing nasal congestion, and elevating the head of the bed; a dentist-fitted oral appliance can help, and CPAP is the gold standard if sleep apnea is diagnosed, with surgery reserved for structural causes. Seek medical evaluation promptly if snoring is loud and frequent or there are breathing pauses, gasping, morning headaches, or daytime sleepiness, since these can signal obstructive sleep apnea and affect whether you need a dental device, CPAP, or other treatment. There are several factors to consider; see below for important details that can guide your next steps.

To stop snoring, start with weight loss, side sleeping, avoiding late alcohol and sedatives, quitting smoking, treating nasal congestion, and doing daily throat exercises; if snoring persists, dentist-fitted oral appliances can help, CPAP is best for moderate to severe sleep apnea, and surgery is a later option.

Clinicians tell idiopathic hypersomnia from narcolepsy by patterns of symptoms and sleep studies: hypersomnia usually involves very long night sleep and pronounced sleep inertia with no cataplexy, whereas narcolepsy shows sudden sleep attacks, REM-related hallucinations or paralysis, and cataplexy in type 1. On testing, an overnight polysomnogram followed by an MSLT with mean sleep latency of 8 minutes or less and two or more sleep onset REM periods suggests narcolepsy, and low CSF hypocretin confirms type 1. There are several factors to consider that affect treatment choices, safety, and next steps; see below for key differences, red flags, and exactly which tests to ask about.

There are several factors to consider; see details and next steps below.

Microsleep episodes are involuntary, seconds-long sleep lapses that can happen even with eyes open, showing up as blank stares, head nods, slowed reactions, memory gaps, and automatic behaviors, especially with sleep deprivation, shift work, monotonous tasks, certain medications or alcohol, and sleep disorders like sleep apnea.
