It's Common to Get Headaches After Napping

If you sometimes wake up from a nap with a pounding headache, you're not alone. Many people experience headaches after napping, especially longer naps. The good news is understanding the cause can help you prevent post-nap headaches.

Headache Triggers During and After Naps

Several factors during and after napping may contribute to headaches including:

  • Sleeping in an uncomfortable position that strains the neck or shoulders
  • Experiencing a sudden drop in stress hormones when you wake up
  • Dehydration or low blood sugar while sleeping
  • Sleep disorders like sleep apnea or REM sleep changes

You May Be More Prone to Headaches

If you already deal with headaches or migraines frequently, you may be more susceptible to headaches during or after naps. Any disruption in normal sleep cycles can be a trigger.

How Nap Length Affects Headaches

The length of your nap can impact your likelihood of waking up with a headache. Longer naps of 60-90 minutes appear most closely linked to headaches upon waking.

Short Power Naps Don't Disrupt Sleep Cycles

A short power nap of just 15-20 minutes allows you to recharge without going into deeper stages of sleep. You are less likely to wake up groggy or with a headache from short catnaps.

Long Naps Lead to Sleep Inertia and Headaches

Sleeping longer disrupts your sleep architecture. Waking up suddenly from slow-wave or REM sleep leaves you confused, foggy, and prone to headaches due to sleep inertia.

Improving Sleep Habits to Prevent Headaches

Adjusting some of your sleep habits and nap routines can help minimize headaches whether you regularly deal with migraines or get them sporadically after napping.

Watch Nap Duration and Timing

Limit naps to 15-20 minutes, and avoid napping too late in the day which can make it harder to fall asleep at night. Creating an ideal nap sanctuary can also help with comfort and headache prevention.

Stay Hydrated and Time Snacks Strategically

Dehydration and blood sugar changes commonly trigger headaches. Drink water before and after napping, and if napping longer have a small protein-based snack beforehand.

When to See a Doctor About Post-Nap Headaches

Occasional headaches after napping usually aren't concerning. But if you regularly deal with severe or persistent headaches related to sleep, it’s important to talk to your doctor to rule out underlying conditions.

Sleep Apnea Can Cause Headaches

Sleep apnea, involving breathing interruptions that disturb sleep, is closely tied to morning/waking headaches even after just a nap. An evaluation for sleep apnea may be recommended.

Evaluate Medications and Sleep Disorders

Certain medications and health issues can impact sleep cycles and architecture. A sleep study may help diagnose conditions like narcolepsy or REM sleep behavior disorder that could contribute to sleep-related headaches.

Making positive sleep hygiene changes is wise, but recurring severe headaches always warrant medical advice to explore other potential causes.

FAQs

Why do longer naps cause more headaches?

Long naps over 60-90 minutes disrupt normal sleep cycles, often causing you to wake up during slow-wave or REM sleep. This sleep inertia where you feel groggy and confused can trigger bad headaches.

Can sleep apnea cause headaches after naps?

Yes, sleep apnea increases the risk of headaches with sleep disturbances. The breathing interruptions of sleep apnea negatively impact sleep quality and architecture, making headaches upon waking more likely.

Is napping bad if you get migraines?

For those prone to migraines, any sleep disruption can trigger an attack. Keep naps short and experiment to see if timing naps differently helps. Check with your neurologist for personalized advice if migraines persist despite sleep modifications.

Should you nap if you woke up with a headache?

It's generally best to avoid napping if you woke up with a severe headache after a previous nap. Light activity, hydration, or a snack may help more in the short term. See a doctor if frequent headaches keep occurring with sleep.
