Migraine and Sleep: How They Can Affect Each Other

Sleep and migraine have a complicated relationship. Poor or irregular sleep may contribute to migraine attacks, while migraine pain and associated symptoms can make it more difficult to sleep.

Understanding this connection may help you identify patterns, improve your sleep routine and provide useful information during a medical consultation.

Can poor sleep trigger migraine?

Some people notice that migraine attacks are more likely after a late night, interrupted sleep or a change to their usual routine. Both insufficient sleep and sleeping substantially longer than usual may be associated with attacks.

It is not always possible to identify one specific trigger. Sleep changes may combine with stress, missed meals, dehydration, hormonal changes or other factors to increase the likelihood of migraine symptoms.

How migraine can disrupt sleep

Head pain, nausea and sensitivity to light or sound can make falling asleep difficult. An attack may also wake you during the night or leave you feeling tired and unrefreshed the following day.

Some people experience fatigue, brain fog or mood changes before or after the main headache phase. Although sleep may sometimes provide relief, it does not always leave the person feeling fully recovered.

Common sleep patterns associated with migraine

• Difficulty falling asleep
• Waking repeatedly during the night
• Sleeping later than usual on weekends
• Changing sleep times due to shift work or travel
• Waking with a headache
• Feeling tired despite spending enough time in bed
• Using caffeine to compensate for poor sleep
• Taking long or late daytime naps

Can sleeping longer on weekends cause an attack?

A significant change to your normal sleep schedule may be a trigger for some people. Staying up late and sleeping much longer the following morning can alter the body’s usual sleep-wake rhythm.

This does not mean you must follow an inflexible schedule. Aim for reasonably consistent sleeping and waking times, including on weekends, while still allowing for individual sleep needs.

Sleep habits that may help

Improving sleep habits cannot prevent every migraine attack, but a consistent routine may reduce one source of disruption.

• Go to bed and wake at similar times each day
• Create a calm wind-down routine before bed
• Reduce bright screens and stimulating activities late at night
• Keep the bedroom dark, quiet and comfortable
• Avoid large meals immediately before bed
• Limit caffeine later in the day
• Avoid relying on alcohol to help you sleep
• Keep daytime naps short and avoid napping late in the evening

What if you regularly wake with a headache?

Morning headaches can have several possible explanations. These may include migraine, teeth grinding, poor-quality sleep, medication overuse or a sleep-related breathing problem such as sleep apnoea.

Regular morning headaches should be discussed with your GP. Further assessment may be necessary, particularly if you snore heavily, wake gasping, experience breathing pauses during sleep or feel excessively sleepy during the day.

Keep a combined sleep and migraine diary

Recording sleep and migraine symptoms together may help reveal connections between them. Consider tracking:

• Your bedtime and waking time
• How long it took you to fall asleep
• How often you woke during the night
• How refreshed you felt the following morning
• The timing and duration of migraine symptoms
• Pain severity and associated symptoms
• Caffeine, alcohol, meals and hydration
• Medicines taken
• Changes in stress, exercise or routine

Bringing this information to an appointment can help your healthcare professional understand how frequently attacks occur and whether sleep changes appear to be part of the pattern.

When should you seek medical advice?

Speak with a doctor if migraine or poor sleep regularly affects your work, concentration, driving or daily activities. Medical advice is also important if your headaches are becoming more frequent, feel different from your usual migraine or no longer respond to your established management plan.
