Hot-weather headaches
A recent study found that a 5°C increase in temperature raises the risk of a severe headache in the next 24 hours by 7.5%. There are several possible headache causes that come with hot weather. Here are five of them to watch out for:
- Dehydration. It’s hot, you sweat more, you get dehydrated, which can give you a headache. Dehydration can also drain your body of electrolytes. So stay hydrated – water is good, but sports beverages can help replenish electrolytes, especially if you are exercising vigorously.
- Heat exhaustion. A headache may be just one symptom of getting overheated. Watch out for muscle cramps, dizziness, fatigue, and excessive sweating. If you experience these symptoms, go lie down in a cool place and rehydrate gradually. Prevent heat exhaustion by staying well hydrated and watching your activity in the heat.
- Strains. If you’re out playing sports, you can strain muscles in your back, shoulders, or neck, and these can result in headaches later on. They will go away – but you may want a pain reliever to help. Also, bright sun on unprotected eyes can lead to squinting, which can make those eyebrow muscles tired, sore, and achy. Wear a hat and sunglasses.
- Lack of sleep. Days are longer and there’s more light out – you may be getting less sleep, which can make you more susceptible to headaches, especially if you suffer from migraines.
- Air pressure. A drop in air pressure, which comes with a warm front, can be a migraine trigger. Watch the forecast and be prepared!
