I just watched an amazing National Geographic special called “Killer Stress: Why Zebras Don’t Get Ulcers”. It’s definitely worth watching if you can find it. The show deals with they physical ramifications of stress on the human body by looking at how animals deal with stress. The program is based on the work of Dr. Robert Sapolsky who is a Professor and researcher at Stanford University. He explains that in nature, stress occurs for a very good reason: to save an animal’s life.
Zebras and Stress
Dr. Sapolsky first takes us through zebras and how they deal with stress. In the wild, zebras get stressed primarily for one reason: a predator, such as a lion, is chasing them because it wants to kill them and eat them. In this case, stress is a good thing, a very good thing. It causes all of the zebra’s resources to be channeled into one thing: keeping the zebra alive. What’s happening internally is that the zebra is temporarily knocked out of homeostatic balance. The definition of homeostasis is: balance or equilibrium, typically between the chemical environment of the body and the external environment. This means that the normal day-to-day functioning of the body stops, and anything that is not immediately pertinent to keeping the zebra alive is abruptly halted. When a lion is chasing you, it’s no time to ovulate! It is a time to run like hell and get away. So the body is flooded with adrenaline and noradrenaline to help the zebra run faster and harder.
But the amazing thing about the zebra is what happens after the chase (if it’s not eaten that is!). It goes back to normal. All of its systems return to a homeostatic balance as if nothing has happened. Now it can ovulate and do all of the things that it needs to do for the majority of the time it’s alive. Only for a very small percentage of a zebra’s life is it actually being chased by a lion. And when it’s not being hunted, it just lets it all go. It doesn’t sit there and dwell on the fact that a lion just chased it to make zebra meat of it. He doesn’t keep talking to his friends about “what a close call” that was and how “he just can’t get over it.” And so the zebra is not living in a state of chronic stress. It is aware of it’s surroundings, but it is not in a state of stress unless an immediate threat exists. There are no “perceived” or future threats that it is stressed over. Seems like a perfectly natural and healthy way to live.
Humans and Stress
It seems that humans have a lot to learn from zebras when it comes to stress management. Unfortunately many people today live in a state of chronic stress, despite the relatively safe environments that most of us live in. We no longer have to run from lions or worry about being crushed by a mammoth. And in the absence of real life threatening situations, we have created ways to stress ourselves. The body cannot differentiate between different types of stresses, so whether our lives are in peril or we are just pissed off because someone cut us off on the freeway and we’re seething and yelling, the body interprets these things the same. And unfortunately for humans, we are not good at letting the stress go and returning to a normal state. We dwell on things. In fact, we dwell on things that have already happened, and we dwell on things that may happen. Dwelling on things is some people’s full time job.
That means that often times humans are in a state of constant stress. And as we’ve learned, when we are stressed, our bodies’ chemical systems are off balance. One of the major systems that suffers is the immune system. And when the immune system is down, we get sick. Tomorrow we’ll talk more about the physical effects of stress on the human body and what can be done.

Farmed salmon would actually not have pink flesh were it not for synthetic astaxanthin being added to their diets. Because they are not roaming the seas and rivers and naturally eating prey with astaxanthin inside them, such as krill, they would not be getting any astaxanthin in their diet in a farmed environment. So salmon farmers add synthetic astaxanthin to their food to get a pink color. In fact these synthetic colorings contribute 15%-25% of the cost of commercially farmed salmon feed. While it is expensive, what consumer would want to eat a white fleshed salmon? But even with synthetic feed, farmed salmon can’t compare to wild salmon in their deep, pink and almost reddish flesh. The next time you are at a fish counter in your local market, take a look at the farmed salmon’s coloring versus the wild salmon’s coloring and you will see the difference.
“Party Omelet” Ingredients:
The FDA has tried in the past to legislate official definitions of various terms such as hypoallergenic or natural, but these regulations were overturned in a court of law. So now any company can use these, and several other terms, on products in any way they see fit.
many fabric softeners contain harsh chemicals and toxic ingredients that can harm you or your family. We all want our clothes to come out of the wash soft and feeling good, so try white vinegar instead. Just add white vinegar to the fabric softener area of your washing machine. There’s nothing harmful or toxic in white vinegar, so it won’t hurt your clothing or your skin. Not only does it soften your clothes, but it also brightens whites and helps to get stains out. And an added benefit is that it cleans the washing machine while you’re doing laundry. You may notice a vinegar scent in the machine after the load is done, but don’t worry, it won’t leave your clothes smelling like vinegar. They’ll just be soft and lovely.
