Sleep Concern

I am sleepy during the day

Persistent daytime sleepiness that interferes with focus, energy, and safety.

Overview

Daytime sleepiness is more than the ordinary afternoon dip — it is a persistent, hard-to-resist urge to sleep that intrudes on your waking hours regardless of how much time you spent in bed the night before. It can surface as nodding off in meetings, fighting to keep your eyes open behind the wheel, or a fog that never quite lifts. When sleepiness becomes a feature of your days rather than an occasional visitor, it is a signal that something — quantity, quality, or an underlying disorder — is not being met.

Common Causes

Chronic insufficient sleep — the most common cause, where accumulated sleep debt quietly builds night after night.
Undiagnosed or undertreated sleep apnea, which fragments sleep silently and leaves the brain starved of restorative rest.
Circadian rhythm misalignment, such as shift work, jet lag, or a delayed sleep phase that pits your schedule against your biology.
Sleep quality disrupted by frequent micro-arousals, restless legs, or periodic limb movements.
Underlying sleep disorders including narcolepsy or idiopathic hypersomnia, where the brain's regulation of sleep and wakefulness is itself affected.

What You May Be Experiencing

An irresistible urge to sleep during sedentary or low-stimulation moments — meetings, reading, or driving.
Needing long naps or multiple caffeinated drinks just to stay functional.
Difficulty concentrating, slow thinking, or memory lapses during the day.
Irritability or low mood linked to poor daytime alertness.
Sleep that 'should be enough' on paper but leaves you struggling to stay awake by mid-afternoon.

Dr. Morse's Approach

Dr. Morse treats daytime sleepiness as a symptom that demands an explanation, not a problem to push through with caffeine. Her first question is always 'why' — is the sleep enough, is it restorative, and is the wake system working as it should? She pairs a careful clinical history with objective tools — sleep diaries, actigraphy, and formal sleep studies when indicated — to separate insufficient sleep from a true sleep disorder. The distinction matters, because the right answer is very different for someone who needs more sleep than for someone whose sleep is being quietly interrupted by apnea or whose wakefulness regulation is impaired. She is deliberate about not normalizing sleepiness that is affecting safety, work, or quality of life.

Treatment Options

Behavioral

Sleep diary and actigraphy to reveal hidden sleep debt; protected, consistent sleep-wake scheduling to restore a healthy rhythm.

Lifestyle

Strategic napping, managed caffeine timing, bright morning light, and protecting a full 7–9 hour sleep opportunity every night.

Medical

Diagnostic sleep study when apnea, narcolepsy, or another sleep disorder is suspected, followed by targeted, evidence-based therapy for the identified cause.

Your Night-time Routine

A practical, step-by-step wind-down built around this concern's specific drivers. Follow it consistently for two to three weeks — rhythm, not perfection, is what resets sleep.

1
On waking
Get bright outdoor light within 30 minutes of waking — it anchors your circadian alerting signal for the day.
2
2:00 PM
Last caffeine — later caffeine fragments sleep and deepens the next day's sleepiness.
3
8:00 PM
Wind-down begins; dim the lights and step away from screens so melatonin can rise.
4
9:30 PM
Protect a consistent 7–9 hour sleep window at the same time every night — sleep debt is the most common cause of daytime sleepiness.
5
10:00 PM
Lights out. If you snore, wake unrefreshed, or have been told you pause in your sleep, raise it with a clinician — sleep apnea is a hidden driver of daytime drowsiness.

When to Seek Help

Daytime sleepiness that persists despite a full, consistent sleep schedule, or that occurs with loud snoring, witnessed breathing pauses, falling asleep at inappropriate times, or any near-miss while driving, should be evaluated promptly. Sudden-onset severe sleepiness, sleep attacks, or sleep paralysis warrant urgent specialist assessment for narcolepsy or related disorders. Never ignore sleepiness behind the wheel — it is a safety issue, not an inconvenience.
