Influence of binaural beats on ideomotoric coordination
Pavlovič, Ondřej ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Name: The effects of binaural beats on sleep quality: a systematic review Aims of the study: The main objective of this study is to present the possibilities of influencing stress and sleep, to determine the effect of binaural beats (BB) stimulation on sleep quality and parameters, and to determine the specifics of effective BB therapy based on the available data. Materials and methods: This systematic review includes scientific articles and clinical studies published in relevant and/or peer-reviewed journals and conference proceedings. Three electronic databases (Web of Science, Scopus, PubMed) were searched for all available sources published from 2000 to January 2023 in English language. The search was conducted using relevant keywords and their combinations. The screening and subsequent process of elimination was based on set of eligibility and inclusion criteria. Results: Total of fourteen studies met the eligibility criteria. BB stimulation increased subjectively perceived sleep quality and reduced mental tension. Objectively, it reduces time of falling asleep, accelerates the onset of deeper sleep stages (N2 and N3) and increases their duration, as well as the total sleep time. The parameters optimal for effective BB stimulation can be laid out as follows: BB in the frequency range of 2 to 4...

Sleep and the consequences of its lack on university students
Soukupová, Barbora ; Thorovská, Alena (advisor) ; Zvírotský, Michal (referee)
This bachelor's thesis is called Sleep and the consequences of its lack on university students. The work is divided into two parts. In the theoretical part are mentioned general characteristics of sleep, history, circadian rhythms, phases and meaning of sleep. Furthermore, attention is also paid to selected sleep disorders, possible causes, and finally the consequences that can occur during sleep deprivation. The practical part is carried out with the help of semi-structured interviews with respondents, followed by an analysis of the interviews, a comparison of individual data and a discussion in which the answers to the research questions are summarized and the results compared with the professional literature. The main goal was to find out the consequences of lack of sleep on university students, when it was found that the most common problems are with attention, memory and mood changes, as well as greater susceptibility to diseases. A partial goal investigated the possible causes that contribute to impaired sleep on university students. The research showed that the most common causes were stress and caffeine. Another partial goal was to find out how the quality of sleep subjectively changes in university students during the exam period. The results pointed to a reduction in sleep time, worsening...

Endocrine and Metabolic Aspects of Various Sleep Disorders

Endocrine and Metabolic Aspects of Various Sleep Disorders MUDr. Zuzana Vimmerová Lattová Abstract: Recent epidemiological and experimental data suggest a negative influence of shortened or disturbed night sleep on glucose tolerance. However, no comparative studies of glucose metabolism have been conducted in clinical sleep disorders. Dysfunction of the HPA axis may play a causative role in some sleep disorders and in other sleep disorders it may be secondary to the sleep disorder. Moreover, dysfunction of the HPA axis is regarded as a possible causative factor for the impaired glucose sensitivity associated with disturbed sleep. However, data on HPA system activity in sleep disorders are sparse and conflicting. We studied 25 obstructive sleep apnea (OSA) patients, 18 restless legs syndrome (RLS) patients, 21 patients with primary insomnia and compared them to 33 healthy controls. We performed oral glucose tolerance test and assessed additional parameters of glucose metabolism. The dynamic response of the HPA system was assessed by the DEX-CRH-test which combines suppression (dexamethasone) and stimulation (CRH) of the stress hormone system. Compared to controls, increased rates of impaired glucose tolerance were found in OSA (OR: 4.9) and RLS (OR: 4.7), but not in primary insomnia. In addition, HbA1c...
