Can summer heat cause migraines?

Yes, the summer heat can trigger migraines in some people. It is thought that summer heat may act as a "trigger" for migraine by increasing blood flow to the head and reducing melatonin levels (a hormone involved in controlling sleep). Heat can also exacerbate existing migraine triggers such as stress, dehydration, or tiredness. Heat is especially a problem if you are living in humid climates, as this can add additional strain and contribute to the development of a migraine attack and heat-related illness.

What are the symptoms of a migraine headache caused by summer weather?

A migraine due to hot weather has several symptoms. It usually starts with a dull ache or throbbing pain on one side of the head, which may then spread to both sides. Accompanying this is nausea and vomiting, sensitivity to light and sound, confusion, difficulty concentrating, fatigue, heat exhaustion symptoms, and severe headaches.

Other symptoms might be a feeling of tightness in the neck or shoulders, dizziness, sweating, and even visual disturbances such as seeing stars or flashes of light.

Due to these symptoms, you can also experience difficulty concentrating, reduced productivity, and mood swings.

In severe cases, it can lead to increased heart rate, heat stroke, rising body temperature, and other heat-related illnesses.

If you suffer from frequent headaches or migraine attacks, contact your doctor.

How do you prevent migraines in hot weather?

You can do several things to prevent summer heat from triggering migraines and treat headaches.

Drink plenty of fluids

Staying hydrated helps reduce the effects of summer heat. Make sure to drink plenty of fluids throughout the day and avoid caffeinated or sugary drinks. Alcoholic drinks are also a no-no. Staying hydrated helps reduce the effects of summer heat and reduces the possibility of a heat headache and heat exhaustion.

Wear loose-fitting clothing

Tight clothing can lead to increased body temperature. Wearing lightweight and breathable clothing helps keep your body cool. Choose bright colors that reflect the sun's rays so you don't absorb too much heat from the summer sun. A wide-brimmed hat is also recommended to protect your face and neck from direct sunlight.

Avoid overheating

Try to stay in cool indoor spaces as much as possible when it's hot out. If you must be outdoors, wear light-colored clothing and a wide-brimmed hat to protect yourself from the sun. Use fans, air conditioners, or open windows to maintain a comfortable room temperature.

Avoid strenuous physical activity

When it's hot outside, opt for more moderate exercise instead to prevent a heat-related headache. When you do want to exercise, make sure you stay hydrated and wear light-colored breathable clothing.

Avoid other migraine triggers

Some summer activities, such as barbecues or swimming in chlorinated pools, may also be potential triggers for migraines. Pay attention to your environment and avoid potential triggers whenever possible.

What should you do if you experience a migraine?

If you experience a heat-induced migraine (summer migraines), you should take immediate action to reduce your symptoms.

  • Taking over-the-counter (OTC) pain relievers such as ibuprofen or aspirin to reduce heat headaches

  • Placing a cold compress on the forehead, temples, and back of the neck for relief

  • Seek medical help if the headache persists for more than two days despite at-home measures

How to Keep your migraine medication cool in the summer?

Migraine injectable medications like Emgality, Aimovig, and Ajovy are temperature-sensitive. They must be kept refrigerated and can quickly degrade in the summer heat. To keep them safe, it is best to store them cool.

You can achieve this by placing your medications in an insulated medication travel cooler from 4AllFamily.
