Stress: Tolerable Today, It Could Kill You Tomorrow

Stress: Tolerable Today, It Could Kill You Tomorrow
The ability to delude yourself may be an important survival tool.

"I work better under pressure." "I need a deadline to crank me up to do my best work." These excuses for adopting stress instead of independent work skills and developing an ability to focus on work at hand may be too much cost for too little benefit.
It's like saying that you can type better with one hand tied behind your back. Or that you perform better at sex when you are impaired with alcohol or drugs. Believe it if you will, but it's still not true. In the final analysis, stress always does more damage than good.
Long term, stress can shorten a "normal" lifetime (dying of natural causes) by three to seven years. It compromises the immune system, meaning that a reduced immune reaction to an attack by viruses or bacteria means a person will get sick. The hormone cortisol is emitted by the adrenal gland to reduce the damaging effects of stress. It's part of our natural "fight or flight" response to danger. But if the stress continues, this strong hormone continues to be pumped into the body. That can result in impaired cognitive performance, thyroid problems (the thyroid prompts the brain to act in many ways, so the brain is affected as well), blood sugar imbalances, higher blood pressure. It can even cause an accumulation of abdominal fat. No one is certain today what effects cortisol exposure can have on the brain, including mood, temper, sleep pattern and personality as each person may react differently to its long term effects.
It is known, through studies, that long term exposure to cortisol causes damage to the human hippocampus, which is very important to learning new things and to memory of what a person has learned.
In a 2010 study by the American Psychological Association, money, work, financial future, family and relationships caused the greatest amount of stress for Americans. Stress itself may be tied to cancer, though the exact linkage is unclear.
Can it cause a broken heart? Takotsubo cardiomyopathy, or "broken heart syndrome," occurs when the bottom part of the heart balloons out, caused when grief or another major stressor floods stress hormones into the heart. Yes, a person can die of a broken heart and the causes are both physical and emotional.
High levels of cortisol in pregnant mothers has been associated with lower IQs in their children, tested at age seven. It has also been associated with autism, though whether stress in mother or baby actually causes autism has not been proven.
One way of avoiding job stress is to have a career in a job expected to be obsolete within a few years. CareerCast.com, in a survey of 200 professions, found bookbinders have the least stress of any in 2011. Firefighters and airline pilots have the most. Another way is to move to a less stressful location. Portfolio.com found Salt Lake City, Utah, the least stressful city among 50 studied in the United States. Detroit took top spot as the most stressful.
This may come as a surprise to some, but not at all to others. Texas A&M International University gave 103 test subjects several stressful tasks, then had them play violent video games. Their stress eased considerably. Best results: Hitman: Blood Money and Call of Duty 2. For those under great stress, virtual violence decreased their bodily reactions to stress.
Militaries handle stress differently. They have their soldiers eat veggies. Military Medicine magazine reported that Yale researchers found eating carrots and potatoes boosted a soldier's cognitive functioning after intensive sessions of survival training. The militaries call it "carbohydrate administration," but it's simply eating complex carbs of any kind. Eating simple carbohydrates like cookies and cake didn't do the trick.
A sudden change of diet can cause stress as well. Going on a restrictive diet quickly (without easing into it) can cause depression or anxiety, according to a study by neuroscientists at the University of Pennsylvania who studied sudden changes of diet with mice that had been fattened up then had their calories severely limited. What is a stressor to a mouse? One method used by the researchers was hanging the mice by their tails for six minutes.
Louisiana State University researchers tried it differently. They caused their test rats to be subjected to random electric shocks to their feet. Then the rats were allowed to self administer intravenous doses of cocaine. As the stress was increased, the rats gave themselves more cocaine. [Anyone who doesn't generalize on that finding is simply not thinking enough. Why do we take so many drugs these days? A more pertinent question might be why do we not teach kids in high school how to cope with stressors in their lives before they resort to possibly harmful alternatives?]
Eating excessively and obsessively is a reaction to constant stress. Researchers at the U.S. National Institutes of Health and Portugal's University of Minho stressed lab rats then allowed them to self access treats. Trained to press a level to receive treats, stressed rats continued to press the level after the stress had stopped and even after they had been fed a meal. The brains of the rats showed shrunken neurons in the dorsomedial striatum, an area of the brain associated with goal directed behaviour, and growth in the dorsolateral striatum, which is related to habitual behaviour. In other words, constant stress caused the rats to habitually overeat.
Do you wonder if overly stressed researchers reduce their stress by conducting experiments on lab rats and mice?
We will conclude this article with an anecdote that has been circulating the internet in recent months.
A young lady confidently walked around the room while explaining stress management to an audience.
With a raised glass of water (everyone knew that she was going to ask the ultimate question, "half empty or half full?"), she fooled them all.
"How heavy is this glass of water?" she inquires with a smile.
Answers called out ranged from 8oz. to 20 oz.
She replied, "The absolute weight doesn't matter. It depends on how long I hold it. If I hold it for a minute, that's not a problem. If I hold it for an hour, I'll have an ache in my right arm. If I hold it for a day, you'll have to call an ambulance. In every case, it's the same weight, but the longer I hold it, the heavier it becomes."
She continued, "And that's the way it is with stress. If we carry our burdens all the time,sooner or later, as the burden becomes increasingly heavy, we won't be able to carry on.
"As with a glass of water, you have to put it down for awhile and rest before holding it again. When we're refreshed. we can carry on with the burden. So, as early in the evening as you can, put all your burdens down. Don't carry them through the evening and into the night.
Pick them up tomorrow. "Whatever burdens you are carrying now, let them down for a moment. Relax, pick them up later after you've rested. Life is short." There may not be so many then and they won't be so heavy.
That's one way we can all learn to cope with stress in our lives.

Why You Won't Likely Become Senile

"It is a mistake to regard age as a downhill grade toward dissolution. The reverse is true. As one grows older, one climbs with surprising strides."
- George Sand

We come to believe that most people who live long enough will become forgetful, absent minded, even confused about many things. We call it senility.

Isn't senility an inevitable disease for most people? No. It's the most preventable disease we know about. Senility is the direct result of mental inactivity for too long.

Most of us know that our muscles atrophy if they are not used. A person with a broken leg, for example, might find the muscle mass in the healed leg much reduced when the cast (or other device) comes off from what it was before the break. Senility is nothing more than atrophy of the brain.

The brain atrophys when it isn't used enough for problem solving and heavy thinking. Our brains, like the rest of our bodies, are built for heavy work. If they don't get enough work regularly, they lose the potential and strength they once had.

"Use it or lose it" applies as much to the brain as it does to the rest of our bodies.

Heavy brainwork even uses up a fair amount of energy, about 31 percent as much as heavy lifting. But we can think for longer than we can lift heavy weights, so thinking is good exercise.
Watching television is not brain exercise. The brain gets less exercise when we watch TV than it does when we dream.

A working brain solves problems, creates new work or considers the various factors that influence a given situation. Television does that work for us, which is why some programs for adults aim at a mental age of early adolescence. Our brain gets almost no work when we watch television.

Senility can be turned around if caught in time and if the person wants to change. However, it requires considerable dedication and determination for a person who is not used to using his brain to work it heavily for an extended period of time every day. Reading a newspaper is good if the person thinks about each item he reads. Reading books is another excellent form of exercise for the brain.

Nature provides that we can become something more than we ever were before as we age. When our bodies stop performing the way they used to when we were younger, our brain should be able to take over and turn us into a new and magnificent person.

Those who have accomplished this change know how dramatic it is and how much better they feel about themselves while their bodies get achy and creeky.

The biggest hurdle is to persuade a lazy brain to exercise when it has been so comfortably ensconced in lassitude for so long.

But it's worth the mental exercise to avoid becoming a breathing vegetable in a nursing home for the last years of our lives.
