Around 180 million Americans contend with tension and migraine headaches, making them the top two nervous system disorders in the country, according to a new study that looked at 36 unique neurological health conditions that affect more than half the U.S. population.

If you’re battling tension headaches, you may be surprised to learn that stress isn't the only cause. Poor posture, neck strain, arthritis (in the neck or shoulders), sleep apnea, and TMJ (temporomandibular jaw disorder) are all possible triggers.

That's why it’s so important to talk to your primary care physician about your tension headaches and find out the root cause.

In addition, practice muscle relaxation through meditation, deep breathing, massage, and the use of heat.

For migraine headaches, there are several medications that can prevent or stop attacks — but they’re often contraindicated for anyone with cardiovascular concerns. These meds include triptans (such as pills, shots, nasal sprays, and dissolving tablets) and what are called gepants.

Some medications come in nasal sprays or oral doses, and work within a couple of hours to ease symptoms. Others work to prevent the onset of migraine altogether.

Botox shots every 12 weeks are also effective migraine blockers for many people. And nerve stimulation devices (transcutaneous supraorbital nerve stimulation, external vagal nerve stimulation, and distal transcutaneous electrical stimulation) can be helpful as well.

You can also keep a headache diary to spot triggers, adopt a healthy sleep routine, exercise regularly, and try meditation.
