Why Your Body Feels Hot without Fever?
A Young woman named Lucy, who lived in western Canada, never felt an ache or pain in her life. Just as some people are born deaf or blind, she was born without the sense of pain. But you wouldn’t have envied Lucy if you had known her. Her body was a mass of scars and bruises. Because she lacked the warning of danger that pain provides, she does not know, how pain Signals And Warns body she several times suffered serious burns; the smell of scorched flesh was her first inkling of injury.
She was repeatedly sent to hospital for infections of a kind which the rest of us avoid because pain warns us that we are in need of medical care. Lucy also lacked the internal responses to pain which protect the rest of us.
When you suffer an injury your body responds to the “pain alarm” in a number of ways. Blood which ordinarily circulates through your skin and abdominal organs is rerouted to your brain, lungs and muscles; your heart beats faster and your blood pressure rises all preparations for taking action against the source of the pain. Your liver secretes stored up sugar into your blood stream, and this energy providing sugar is rapidly carried to your muscles.
If the injury is in the vicinity of your head, tears probably flow and your nose runs-the body’s method of washing away harmful substances. Chemical changes occur in your blood to make it clot more quickly, so that less blood will be lost. If the pain is from an internal source, an entirely different set of protective responses may be ushered in.
How does Warns Body?
Your blood pressure may drop, and nausea and other unpleasant symptoms may make you want to lie down and curl up an excellent posture for recovery .Pain has yet another kind of usefulness. After a period of excessive exercise which leaves you with painful muscles, the initial soreness fades away; but the abused muscles immediately become painful again if they are exercised before recovery is complete.
This increased sensitivity-known as “hyperglycaemia❞—one of is nature’s most effective ways of protecting us following an injury. Pain is a sense like vision, taste or smell. Pain sensitive nerve endings are distributed through your skin and organs, and when these endings are stimulated you feel pain. Years of research by three scientists-Dr James
D. Hardy of the University of Penn Sylvan Medical School and the U.S. Naval Air Development Centre, and Dr Harold G. Wolff and Miss Helen Good ell of the Cornell University Medical College have shown that the intensity of pain does not depend upon the amount of tissue injury but upon the rate of injury.

Thus if you immerse your body in hot water at 112° Fahrenheit for six hours you will feel only the slightest pain. Yet at the end of the period your skin will be thoroughly cooked. Conversely, a white-hot iron touched to your skin for a fraction of a second may not even produce a burn, yet you may suffer excruciating pain. “Pain is a sort of speedometer which measures the speed with which tissue damage is occurring,
” Dr Hardy says. “It tells you little about the seriousness of your injuries, but it warns you how rapidly injury will proceed if you don’t take action.” The nerve endings which produce pain are distributed through your body in accordance with an intelligible plan. They are relatively less exposed on the palms of your hands and soles of your feet, where minor injuries are frequent and unimportant.
In the region of the groin and neck, where injuries might threaten your life, pain-sensitive nerve endings are closer to the surface. The grey matter of your brain is protected by your skull and lacks pain nerves altogether. But the arteries which transport blood to the brain are richly supplied with them. Thus headaches are not really brain aches; most are aches in the blood vessels of the head.
Dr Hardy and Wolff and Miss Goodell classified pain into three types. One they called “prickling” pain; this reaches your consciousness immediately after your skin is cut, bruised or burnt. It is sharp, and tells you precisely where the injury occurred. A second or two later you feel the “burning” pain; this is duller, lasts longer and spreads vaguely over a larger area.
The third type is “aching” pain; it arises from nerve endings in your internal structures rather than your skin. The pain suffered in real life, however, may be very different from pain produced in laboratory tests. It may be compounded with worry, fear, nausea and other feelings more important to the victim than the actual pain from the injury.
We often suspect that people whom we call “stoical” are less sensitive to pain than other people, but research says this isn’t so. Most people experience pain in about the same degree. Some just make less fuss about it. Dr Hardy, Dr Wolff and Miss Goodell have demonstrated this by means of a pain thermometer called a “dolorimeter,” from the Latin word for pain, dolour. They define each degree measured on the dolorimeter as one “dol.”

A pinprick or other slight pain which you can barely feel is a Haldol pain; an ordinary headache may measure 2 or 3 dollars. The pain during passing of a kidney stone measures 10 dollars; this is the ceiling above which pain does not rise, even though the cause of the pain continues to increase in intensity. The stoical person may stand an 8-dol pain with less screaming or writhing than others who suffer a 2- or 3-dol pain.
Some people as your dentist will assure you react to a 1-dol pain as if they were suffering the tortures of hell. Each of us may react differently, too, at different times. A prize fighter who ignores intense pain in the ring may squeal like a baby in the dentist’s chair. A football player who hurts his ankle at a crucial point in the game may not feel pain until some time later in the game.
In many illnesses pain lasts long after its warning function has been served—and long-lasting pain, even of minor intensity, can change the gentlest and happiest person into an irritable, angry beast or a depressed and cowering whimpered. Distractions are sometimes effective in alleviating pain. paragraph is pending (Primitive medicine men, wearing grotesque masks, use music, dancing and bitter medicines to distract the patient from his pains.)
Work is also a distraction; a backache or headache which you ignore on the job all day may seem excruciating when you have nothing to do in the evening except think about your suffering. You can find relief from pain by reading or by watching television. For this reason volunteers who bring entertainment or other distractions into hospitals are helping to alleviate pain as well as to speed the idle hours.
The Hardy-Wolff-Good ell experiments show that simple pain relievers such as aspirin act primarily by increasing the amount of nerve stimulation needed to produce pain. A headache which is producing a 2-do pain may disappear after you take aspirin. But a 4-do headache will not be reduced to 2 dollars by aspirin. In fact aspirin will not affect a 4-do pain.
Nor will increasing the dosage help. One or two aspirins at a time are as effective as five or six-and far safer. Mental expectation of pain relief has much the same effect as chemical pain relievers such as aspirin. Dr Hardy and Wolff have compared the effect of aspirin with the effect of fake pills which the patient thinks are aspirin.
They report that about half the pain- relieving effect is produced by the aspirin itself and the other half by the patient’s confident expectation that the tablet will relieve him. Nerve-cutting operations are sometimes performed to quiet pains which yield to no other treatment.
There is danger, how- ever, that nerve cutting won’t work, because sometimes the source of the pain isn’t where it seems to be. To avoid being fooled, the surgeon paralyses a nerve temporarily with injections before cut- ting it. If the pain disappears he knows that he has located the right nerve. Such surgery, however, is used only as a last resort. Our aches and pains, like the sights we see and the sounds we hear, are useful possessions. For this reason, among others, it is wise to grin and bear them.
