What are heat headaches?

Headache is a common disorder of the nervous system, affecting 50-75% of people worldwide each year. The triggers of headaches and migraines can vary from person to person, but headaches can also be a symptom of heat-related conditions.

Heat headaches often occur in hot weather or during physical activities that raise body temperature. It is unlikely that heat headaches are caused by the heat itself. In most cases, the cause is another trigger related to the heat.

Regardless of the rise in temperatures, the causes of headaches are varied and may be a symptom of an underlying health problem. In most cases, however, they are caused by some of our daily habits, such as the foods we eat and the way we eat. Those who are prone to headaches or suffer from them frequently should review their eating habits and eliminate foods that can increase the risk of headaches. In the following article, you will learn which foods are most likely to cause headaches.

What causes heat headaches?

As mentioned earlier, heat-related headaches are not caused by the hot weather itself, but by the way your body reacts to the heat. The most common weather-related triggers of summer headaches and migraines include:

  • Dehydration: when you are exposed to higher temperatures, your body needs more water to compensate for the loss it experiences from sweating (water and electrolytes). Dehydration of the body is thought to trigger headaches because a lack of fluids causes blood vessels to constrict.
  • Heat-related illnesses: Exposure to high temperatures for extended periods of time puts you at risk for heat stroke, one of the precursors to heat exhaustion. Headaches, usually accompanied by dizziness and confusion, are usually one of the first symptoms of heat exhaustion. Heat stroke is often not severe if you can cool down within 30 minutes. If heat stroke does occur, you need to see a doctor.
  • Changes in weather conditions: weather conditions can also cause changes in your serotonin levels. These hormonal fluctuations are a common trigger for migraines, but they can also cause headaches. In addition, research has shown that even a small drop in barometric pressure can trigger migraines or headaches.
  • Sun exposure: In some cases, sun exposure can trigger headaches or migraines, especially in people who suffer from photophobia, a very common condition. Photophobia is a term used to describe an abnormal discomfort of the eyes when exposed to bright light. If left untreated, this discomfort typically leads to headaches or migraines.

The risk of dehydration increases exponentially in summer due to high temperatures, but also if you sweat excessively during exercise. So you should be vigilant and always keep yourself well hydrated by drinking enough water and healthy fluids. In this other article, you will learn what the symptoms of dehydration are and when you should see a doctor to treat them.

Signs of heat headache

Heat or environmental headaches can have different symptoms depending on what is causing them. However, heat headaches usually present with the following symptoms:

  • Mild to moderate pain on both sides of the head.

  • Headache that worsens with activity.

  • Persistent pain that is dull but not throbbing

If your headache is triggered by heat stroke, in addition to the headache, you will also have symptoms of heat stroke, which may include the following:

  • Dizziness

  • Muscle cramps or tightness

  • Nausea

  • Fainting

  • Extreme thirst
  • Weakness or fatigue

  • Rapid but weak pulse

Heat stroke can cause all sorts of symptoms, including palpitations, dehydration, and diarrhea. Continue reading this other article to learn why heat sometimes causes diarrhea and cramps.
