If you’ve noticed that you have more headaches during the summer months, you may be wondering whether the weather is to blame. Some people assume their headaches are due to the heat, but health experts suggest that the heat itself is not likely the culprit. However, summer weather can lead to several things that can trigger headaches in some people. This may be why you experience an uptick in headache symptoms at this time of year.

Here are some factors that can increase the likelihood of having summer headaches:

• Dehydration – When it’s hot outside, your body works harder to stay cool and this can lead to dehydration, especially if you’re not drinking enough water. Even mild dehydration can trigger a headache.
• Humidity – If the air is thick with moisture, it can make it harder for your body to cool down. This stresses your body, which can trigger headaches or make migraines more intense.
• Sunlight – When it’s bright outside, it causes you to squint or strain your eyes, which can lead to tension headaches.
• Sudden weather changes – Shifts in barometric pressure, such as can happen during summer storms or other weather events, may trigger headaches in some people.
• Changes to routines – Aside from the weather, it’s common for people to experience changes to their usual routines during the summer months. Skipping meals, drinking too much alcohol or not getting enough rest are common headache triggers.

So, what can you do to help prevent heat-related headaches?

It’s impossible to completely avoid all headache triggers during the summer, but there are things you can do to make it less likely that a rise in heat and humidity will cause you to experience headache pain. These include:

• Prioritize hydration – One of the best ways to avoid summer headaches is to stay well hydrated. Drink more water than you usually do, especially if you’re spending time outdoors or are sweating. Limit caffeine and alcohol, which can both contribute to dehydration.
• Eat at regular times – Even though you may be busy during the summer, make sure you don’t go too long without food. Doing so can lead to low blood sugar, which can bring on a headache. Pack snacks if you’re going to be out for a while.
• Minimize time in the heat – Try to avoid being out during the hottest part of the day, between 10 a.m. and 4 p.m. Take breaks in the shade or seek air conditioning when possible. Also, wear light loose-fitting clothing, a wide-brimmed hat and sunglasses.
• Keep track of headache triggers – Pay attention to what’s going on when your headaches occur, such as whether you’ve been out in the sun, didn’t sleep well or are off your usual eating schedule. A headache journal can give you clues as to what’s causing your summer headaches.

If you feel a headache coming on, especially if you think it’s triggered by heat and humidity, place a cool washcloth on your forehead or the back of your neck. This may ease symptoms. Many people find that over-the-counter (OTC) pain relievers also provide some relief. But if you get headaches often or your symptoms can’t be managed well with OTC medications or home remedies, ask your doctor for other suggestions for preventing or treating your headache pain.
