Headaches have causes.  What’s causing yours?  Here’s a list of several possible reasons that your head hurts:

1.  Poor posture.  Head pain can happen because of poor posture.  But what causes poor posture?  A weak back or bad  habits when sitting and standing.

2.  Certain foods can cause reactions in blood vessels that lead to headaches.

3.  Poking your chin out too far.  That strains your neck muscles and the muscles at the base of your skull.

4.  Being constipated.  A diet that has too much processed foods and not enough fiber can cause constipation.  So can too little water and poor posture.  When your posture collapses it squashes your intestines so stuff cannot move as it should.

5.  Aspirin deficiency.  No, not really.   🙂   There is no such thing as aspirin deficiency.

6.  Losing the natural curves in your lower back and neck.  You are supposed to have a little space behind your waist and behind your neck.  If you don’t, it’s often referred to as ‘military neck’–too straight.

7.  Having too much of a curve in your lower back or neck.  There is a fine line between too much and too little curve in your spine.  What causes too much or too little curve?  Muscles.  Habits.  Car seats.

Since bodies work in logical ways almost everything that causes pain has a cause.  Pain doesn’t happen without a reason.

I wrote this book to help you understand WHY your head hurts and the steps you can take to make it stop hurting.

If you can get rid of the causes of your headaches or migraines there’s a really, really good chance you can get rid of your headaches naturally. 🙂  That’s what this book will help you do–get rid of the causes.
