As a hormone testing lab, ZRT understands the importance of a well-balanced endocrine system in maintaining overall health.

Hormone balance is achieved through multiple feedback mechanisms, and when any part of the system is thrown out of whack by forces beyond its control, there is a knock-on effect on the rest of the body systems that are under endocrine control.

Such forces can include extreme or chronic stress, or exposure to environmental toxins that enter the body through the air we breathe or in our diets. Substances in the environment that upset the endocrine system are known as endocrine-disrupting chemicals, or EDCs.

For me, when I watch those swimmers cutting through the water at tremendous speed, I just want to get into a pool and see if I could really try to swim faster myself.

We’ve probably all heard by now that “sitting is the new smoking,” and that our health suffers greatly from inactivity. The human body was meant to be in motion at least for an hour or two a day, and this is known to keep the cardiovascular system tuned up as well as preventing excessive weight gain. But did you know that exercise affects levels of neurotransmitters in the body and can actually help you prevent or overcome disorders such as depression?
