You can study the psychology of fear until the cows come home; it’s not going to do much to keep your heebie-jeebies under control when you’re about to jump into a gap in six-foot-thick sea ice.
I shuffle closer to the edge of the five-by-five foot hole that’s been chainsawed into the ice. I have no real reason to be jumping into the frozen-over Hudson Bay. I’ve come up here for a totally different reason—to do a story about igloo building for a men’s magazine. But the trip’s organizers added a couple of extra days onto my itinerary so that I could get a taste for the local Inuit culture—riding on a dogsled, eating raw caribou meat — oh, and going scuba diving under the sea ice. Care to give it a try, Mr. Wise?
I couldn’t say no. Stunts like this are basically what I do for a living. I’m a magazine writer specializing in experiential adventures like skydiving, surfing, and survival training. Along the way, I developed an interest in the psychology of intense pressure and wrote a book on it. So though the idea of scuba diving under ice scares the crap out of me, that’s all the more reason I should do it.
And it does scare the crap out of me. Immersion in 32 degree water sounds bad enough, but to be trapped under six feet of ice as well? There’s a section of my book about how deadly that kind of thing can be. If a diver panics, the instinctive response is to rip away anything that blocks the airway – in this case, the regulator. In an enclosed space far from the surface, there may be no chance to recover from that mistake. Ironically, just knowing that the possibility exists makes it more likely to happen. “Well, let’s see how it goes,” I tell the organizers.
The AP just reported a story that vividly illustrates the incredible capacity of the human brain and body to perform under intense pressure. A Kansas man named Nick Harris was driving his 8-year-old daughter to school last week when he saw a car back up and run over a neighbor’s 6-year-old daughter. “I didn’t even think. I ran over there as fast as I could, grabbed the rear end of the car and lifted and pushed as hard as I could to get the tire off the child,” Harris said.
If you’ve been unusually stressed out in 2009, here’s something else to fret about: Anxiety is not only an unpleasant emotional condition, it’s physically harmful. Chronic elevation of the stress hormone cortisol weakens the immune system, disrupts the memory, and damages the cardiovascular system. Thanks to anxiety your life will not only be more miserable, but shorter.
That’s the case for most of us, at any rate. But a recent study carried out by researchers at King’s College London found out that among people suffering depression, those who suffer from anxiety as well actually have a longer life expectancy. “‘One of the main messages from this research is that a little anxiety may be good for you,” observed team leader Dr Robert Stewart.
In terms of the relationship between mortality and anxiety with depression as a risk factor, the research suggests that help-seeking behaviour may explain the pattern of outcomes. People with depression may not seek help or may fail to receive help when they do seek it, whereas the opposite may be true for people with anxiety.
To put it another way, anxiety can do you a lot of good when there really is something for you to be anxious about. Which is, I suppose, why evolution has bequeathed us with anxiety in the first place. Whatever its downsides, anxiety focuses our attention and motivates us to take action. If you’ve got a serious medical issue, and depression is demotivating you from doing anything about it, then a case of gnawing nerves is just what you need.
