Människans liv med sömnbesvär och hur människor med sömnbesvär upplever kognitiv beteendeterapi

Sleep disorders are a common health problem in western countries. Every third working age person suffers from sleep deprivation and that often leads to other health problems as well. One can end up in a vicious circle, which can further decrease mood and ability to function. The aim of this thesis is to illustrate how sleep deprivation affects the lives of working age population and to deepen our understanding of life with sleep deprivation. Study questions are: how does sleep deprivation affect a working age person’s life and what kind of experiences do people have about cognitive-behavioural therapy as a treatment to sleep disorders. Theoretical perspective is based on clinical nursing science theories and the humanist view of man, which sees human as an entity. The methodology used is phenomenological approach and data analysis is conducted by using Ricœur’s hermeneutic phenomenological interpretation method. The empirical part is divided into two different sections. The material of the study consists of interviews and surveys done by people who have experienced sleep deprivation or sleep disorders. Two interviewees talked about their lives with sleep disorders and there are 21 surveys conducted on people’s experiences on cognitive-behavioural therapy. The partakers in the two sections are different people. The results show that people with sleep disorders can end up in a vicious circle of sleep deprivation and in worst cases a sleep disorder can take charge of a person’s whole life. Sleep disorder can cause shame and fear of stigma. Nevertheless, someone suffering from a sleep disorder can find strength and solutions to control the difficult situation. This study proves that both nursing staff and other people have little information about difficulties in sleeping and awareness should be improved in clinical nursing. A health-care provider has an essential role in preventing someone ending up in a vicious circle of sleep deprivation and cognitive-behavioural therapy can contribute to good health. Reflection at the end of cognitive-behavioural sleep therapy course helps patients to continue their learning process. When someone is sleep deprived, it means that they have control over the situation, but when someone has a sleep disorder, that person does not have the strength to control the situation.

Sleep and Menopause. Hormone Therapy and Sleep Deprivation

This study evaluated the effect of menopause, hormone therapy (HT) and aging on sleep. Further, the mechanisms behind these effects were examined by studying the associations between sleep and the nocturnal profiles of sleep-related hormones. Crosssectional study protocols were used to evaluate sleep in normal conditions and during recovery from sleep deprivation. The effect of initiation of HT on sleep and sleeprelated hormones was studied in a prospective controlled trial. Young, premenopausal and postmenopausal women were studied, and the methods included polysomnography, 24-h blood sampling, questionnaires and cognitive tests of attention. Postmenopausal women were less satisfied with their sleep quality than premenopausal women, but this was not reflected in sleepiness or attention. The objective sleep quality was mainly similar in pre- and postmenopausal women, but differed from young women. The recovery mechanisms from sleep deprivation were relatively well-preserved after menopause. HT offered no advantage to sleep after sleep deprivation or under normal conditions. The decreased growth hormone (GH) and prolactin (PRL) levels after menopause were reversible with HT. Neither menopause nor HT had any effect on cortisol levels. In premenopausal women, HT had only minor effects on PRL and cortisol levels. The temporal link between GH and slow wave sleep (SWS) was weaker after menopause. PRL levels were temporally associated with sleep stages, and higher levels were seen during SWS and lower during rapid-eye-movement (REM) sleep. Sleep quality after menopause is better determined by age than by menopausal state. Although HT restores the decreased levels of GH and PRL after menopause, it offers no advantage to sleep quality under normal conditions or after sleep deprivation.
