It is interesting to observe that some people fall asleep very easily, but some find it very difficult and need sleeping pills. Even the same person may fall asleep very easily at some times in his life but find it very difficult at other times. Why is this?

There are two sets of forces acting against each other which affect sleep onset One group of forces includes good sleep hygiene, falling asleep at the right time of the biological clock, and, of course, being sleepy. The other group of forces includes poor sleep hygiene, trying to fall asleep at the wrong time of the biological clock, being unable to handle stress effectively, and, of course, having a genetic makeup that is of poor quality for sleeping. It is important to increase those forces that facilitate sleep onset and to decrease those that oppose it.

Genetic make-up. Studies of identical twins show that much of our ability to sleep is coded in our genes. Identical twins, who have the same genes, have similar sleep patterns even if they live apart in different environments for years. Some people are born good sleepers and they can sleep at any time of the day and, in fact, anywhere. My wife is a good sleeper, and she could sleep easily at any time no matter what shift duty she was on when she was working as a nurse in the general hospital. My two daughters have different abilities to fall asleep. Melissa is more like me, whereas Melinda sleeps easily, very much like her mother. But for those of us who are not so lucky and have poor quality genes for sleep, we have to improve those factors that facilitate sleep onset so as to tip the balance in favour of the forces that bring about sleep.

Sleep hygiene. This is the most important force in facilitating sleep onset As discussed in chapter 15, Sleep Hygiene, caffeine is the number one enemy; absolutely no coffee or tea. The bedroom is reserved for sleep and sex and no other activities. Leave the clock under the bed, but set the alarm to the same time every morning, even on Sundays and public holidays. A regular waking up time in the morning is an important Zeitgeber for entraining our circadian rhythm to the 24 hour clock. Daytime exercises are good, as they increase the amounts of NREM sleep.

When there is no clear cause for the condition, patients suffering from chronic pain are sometimes referred to a psychiatrist for his opinion. When these patients really unburden themselves they often disclose that they are preoccupied in thinking about some wrong they have done in the past. Over the years they have thought about it a great deal, and in thinking about it in this way, the wrong becomes greatly magnified. They have never told anyone about it. “This is something that I always thought I would bring with me to the grave.” And all the time there has been the thought, “Of course I shall be punished for it.” In the first place the pain may have arisen from some quite trivial cause; but once the pain is there, it soon becomes fixed. Only

half-consciously he thinks, “This is what I have been expecting; I knew it had to come; I am glad it has come at last and I shall get it over.” In a sense he is glad of the pain. By suffering the pain he will ease his conscience of the thing that he has done, and his mind will be at rest again.

On the one hand a patient in this situation wants to get rid of the pain because it hurts him, but on the other hand he wants to keep it, as it expiates his feeling of guilt. The pain lingers on, unrelieved by the various medicines he is given. Expiation never seems complete, so it continues until brought to light and worked through in psychotherapy.

“I wish I were back home with my own people. People I can understand. I’m not at home here. They say nasty things. Rude things. Call me “Old bastard”. But they seem to like me. I can’t understand. I’m not a bastard. I hate it. They laugh. It spoils my life. I wish I could go back to my own country.”

Local idiom and local slang are always confusing to the newcomer. His brain cannot integrate conflicting messages. They seem to like him, but still call him a bastard. Far from being a matter of vilification, ‘old bastard’ is a term of endearment in the Australian vernacular.

I remember, some years ago, the cool reception I received when I addressed the head nurse of an American hospital as ‘sister’. In Australian hospitals the word carries strong overtones of respect, while in America it is a term of familiarity.

In matters as simple as this, the misunderstanding can be rectified by simple explanation. But without such explanation, the individual lives in an atmosphere of uncertainty which can form a background for the development of stress.

If we are secure enough in ourselves these misinterpretations lose their ill effect. We can stand by, and assume there was something in the conversation which we did not understand correctly.
