Introduction

Do your work or leisure activities require a helmet or goggles? If they fit too tightly, you may be setting yourself up for a headache.

Any head wear that puts continuous pressure on your forehead or scalp can lead to what's known as an external compression headache. Common culprits include tight hats, helmets, headbands and goggles.

With most external compression headaches, the solution is as obvious as the cause. Simply remove the head wear causing the pressure.

Signs and symptoms

The pain of external compression headaches is often described as constant pressure. It hurts most where the object is pressing on your head. As long as the head wear is in place, the pain may get progressively worse.

Causes

External compression headaches are caused by any type of head wear that places pressure on the head — including tight hats, helmets, headbands and goggles. Researchers don't know why some people are more sensitive than others to this type of pressure.

Risk factors

External compression headaches can affect anyone who uses head wear. The headaches are more common among people who have migraines. They affect more women than men — possibly because migraines are more common in women.

When to seek medical advice

External compression headaches don't pose any medical concerns. Consult your doctor if the headache lingers or gets worse after removing the head wear.

Complications

External compression headaches aren't associated with any complications.

Treatment

Remove the head wear that's causing the pressure. Further treatment is rarely needed.

Prevention

To prevent external compression headaches, skip the head wear. If head wear is unavoidable, make sure it fits properly and is positioned carefully. Try various styles and sizes as you look for the most comfortable options.
