Morning Headaches: Dehydration, Sleep Apnea, Caffeine Withdrawal, Tension, Migraine, and Medical Conditions

Common Causes of Waking Up with a Headache

1. Dehydration: Insufficient water before bed; fluid loss during sleep via sweat/breathing.

2. Sleep-Disordered Breathing: Sleep apnea or chronic snoring disrupts sleep, causes poor oxygenation and muscle tension.

3. Caffeine Withdrawal: Sudden reduction in caffeine dilates blood vessels, causing headaches.

4. Tension-Type Headache: Most common; mild-moderate pressure around head. Stress, anxiety, sleep disturbances contribute.

5. Migraine: Severe throbbing pain with nausea, vomiting, light/sound sensitivity. Some experience morning migraines.

6. Underlying Medical Conditions: Hypertension, thyroid issues, sinus infections. Persistent/severe headaches need professional evaluation.

Keep a headache journal tracking pattern, severity, and triggers (food, sleep, stress) to aid diagnosis and treatment.
