What Causes Migraines?
What causes migraines? Experts in the field including those involved in research still have a difficult time explaining what causes migraines. In the past they believed it to be a dilation and constriction of blood vessels in the brain1. However, more recently research has pointed not to blood vessels but to nerves.

Being healthy is an important way of life which is enhanced by exercising, eating right and taking care of your body. Sweating, which generally occurs with exercise, allows the skin (the largest organ of the body) to remove toxins from the body; according to a 2011 study published in the Archives of Environmental and Contamination Toxicology4. We wrote about toxins, specifically mercury, in our previous article and would like to follow it up with this one as one possible way to help remove toxins from the body. Sweating can also occur when one uses a sauna which we will look at further.
