What to Do If You Get a Headache in the Heat? Simple Doctor's Tips

Enjoying the summer weather can be challenging if you're dealing with headaches caused by the heat. Here are some expert recommendations to help you stay healthy and headache-free.

Causes of Heat-Related Headaches

Firstly, elevated temperatures can cause blood vessels to dilate, leading to lower blood pressure and reduced blood flow to tissues. Secondly, sweating to regulate body temperature results in fluid loss, causing dehydration. Dehydration thickens the blood, impairing circulation to the brain and triggering sudden vessel spasms. The cycle of dilation and constriction of blood vessels is a primary cause of headaches. Cold drinks can worsen these spasms. It's noteworthy that even in normal conditions, 50% of people experience headaches. Increased temperatures exacerbate these symptoms.

Symptoms and Diagnosis

Look out for "red flags" that necessitate medical attention:

A headache that disrupts your daily activities.
Increased pain with physical activity or while lying down.
Accompanied by skin rashes, fever, or altered consciousness.
Worsening or changing characteristics of the headache.
Hot weather can either trigger headaches or worsen existing conditions.

Prevention

Maintain a headache diary by tracking:

Location of the pain.
Intensity and severity.
Characteristics of the headache.
Possible triggers, including heat or stuffy environments.
Blood pressure and pulse rate.
Other symptoms like nausea, vomiting, or dizziness.
Often, headaches due to temperature changes don't need medication, especially if triggered by factors like:

Drinking cold beverages.
Prolonged exposure to stuffy environments or direct sunlight.
Simple preventive measures can help manage these headaches:

Stay hydrated by drinking 30-40 ml of water per kg of body weight. Choose room temperature or slightly cool water, and avoid alcohol, carbonated, and sugary drinks.
Avoid stuffy environments. Heatstroke can occur even without direct sun exposure.
Steer clear of strong smells, loud noises, and bright lights.
Wear a light-colored, breathable hat.
Take cool showers and use cold compresses on your head. Foot baths with alternating warm and cold water can also help. Dip your feet for 30 seconds until the water temperature equalizes. Continue for about 10-15 minutes, gradually increasing the temperature difference. Similar to the effects of sports or sauna use, this method helps with vessel tension and relaxation.
If you have high blood pressure, keep your prescribed medications handy as heat can worsen symptoms.

Headaches are a common reason for summer doctor visits. Following these recommendations can help you enjoy the weather without health issues. If headaches persist regardless of the weather, consult a doctor to determine the underlying cause.
