“…Scientists [20,21] are investigating the correlations between the heart rate disturbances and GMF, but do not analyse data according to different GMF frequency intervals. Sasonko et al (2018) performed investigation about correlation between RR, QT and PQ intervals with number of atmospheric factors and global GMF [22].…”

“…6). In the evening a tendency of negative correlations was observed in SDelta [0-3.5] Hz band ( (21) = -0.330; = 0.143) and in SAlpha [7][8][9][10][11][12][13][14][15] Hz band ( (21) = -0.338; = 0.134) but significant negative correlations were observed in GMF in SBeta [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]] Hz band and QRS duration ( (21) = -0.441; = 0.045). In summary it can be stated that changes in the QRS duration and GMF are associated with adaptations in the heart's regulatory mechanisms.…”

The aim of this research was to identify the interactions between Earth's local time varying magnetic field and cardiovascular system parameters in women, performing sedentary work, during their workweek. The tasks of research: 1. To examine the relationship between the Earth's local magnetic field and the electrocardiographic parameters of women performing sedentary work, during the workweek. 2. To examine the relationship between the Earth's local magnetic field and arterial blood pressure of women performing sedentary work, during the work week. The methods used: electrocardiographic monitoring and arterial blood pressure measurement. The Earth's magnetic field data was obtained using a magnetometer located in the town of Baisogala. Every female was assessed four times: before and after work on Monday, before and after work on Friday of the same week. Participants of the research: the research group consisted of 21 females who perform sedentary work (average age ± SD-50.1±9.5 years). Conclusions of the research: 1. The most significant correlations between local GMF and ECG and arterial blood pressure parameters were found with the low frequency field, the most often in SDelta [0-3.5] Hz and STheta [3.5-7] Hz bands. 2. The correlations between ECG parameters (RR, JT and QRS intervals ant ST amplitude) during the workweek changed from negative to positive, which appears to be associated with fatigue influence on person sensitivity to local GMF. 3. Systolic and diastolic arterial blood pressure changed in different ways. The correlations between local GMF and diastolic arterial blood pressure were especially pronounced. 4. All ECG and arterial blood pressure parameters showed great variability in correlation with local GMF. It can be associated with changing human sensitivity to GMF due to increasing fatigue.

“…При этом как у отдельных клеток, так и у организма в целом реакция на внешние воздействия зависит не только от их характера и силы, но и от свойств самих биообъектов (7). В период магнитных бурь обостряются хронические заболевания сердечно-сосудистой, центральной нервной систем, нарушается кровоток (8)(9)(10), заметно усиливается секреция адреналина надпочечниками, изменяется состояние вегетативной нервной системы, которая регулирует работу внутренних органов и желез внутренней секреции (11). С изменением геомагнитной активности связана продукция мелатонина (12,13), который участвует в регуляции циркадных ритмов, улучшает работу эндокринной (14), иммунной (15), репродуктивной (16,17) систем.…”

Магнитные бури-одни из важнейших абиотических факторов, воздействующих на биообъекты. Влияние магнитных бурь носит сложный характер и может проявляться в организме на разных уровнях. В период геомагнитной активности увеличивается частота обострений хронических заболеваний, нарушаются функции ряда систем. Сперматозоиды подвергаются действию различных биотических и абиотических факторов как в организме, так и вне его. Однако сообщения о влиянии геомагнитной активности на репродуктивную функцию, в частности на количество и качество спермы, объективно весьма ограничены, а для сельскохозяйственных видов животных подобных сведений в доступной литературе мы не обнаружили. Цель нашей работы заключалась в исследовании взаимосвязи геомагнитной активности с количественными и качественными показателями спермопродукции у быков-производителей голштино-фризской породы (n = 10, АО «Головной центр по воспроизводству сельскохозяйственных животных», Московская обл., 2018 год). Мониторинг К-индекса геомагнитной обстановки проводили по данным Институтаземного магнетизма, ионосферы и распространения радиоволн им. Н.В. Пушкова РАН (г. Москва). Статистический анализ выполняли с помощью программы SPSS v.15.0 с использованием однофакторного дисперсионного анализа (ANOVA) (фактор, влияющего на биологическую полноценность спермы быков-производителей,-К-индекс). Сравнение показателей между группами проводили методом Scheffe-test. Качество сперматозоидов в эякулятах оценивали с использованием световой микроскипии (Nikon Eclipse Ni, «Nikon», Япония) и программного обеспечения Argus-CASA («ArgusSoft», Россия). Полученные в настоящей работе результаты показывают, что магнитная буря достоверно влияет на спермопродукцию у быков-производителей. Статистически значимые различия были установлены по объему эякулята (F = 6,49; p < 0,05) и содержанию непрогрессивно-подвижных сперматозоидов в эякуляте (F = 8,36; p < 0,05). В период магнитной бури (К-индекс  5,0) объем эякулята, полученного от быков-производителей, снижался на 28,2 % (p < 0,001) по сравнению с периодом отсутствия геомагнитных возмущений (К-индекс  1,0). Геомагнитные возмущения привели к снижению активности сперматозоидов на 11.3 % (p < 0,001). Ключевые слова: магнитная буря, быки-производители, сперматозоиды, подвижность сперматозоидов, морфология сперматозоидов, хроматин, яДНК, индекс фрагментация ДНК, CASA.

Introduction NexQuest Natural Frequency Technology ® (NFT ® ), intended to enhance biological function using naturally occurring frequencies, may be a nonpharmacological intervention to improve stress and health. The study purpose was to determine the effectiveness of NFT ® for improving stress, sleep quality, mood, and cognition in adults. Methods Using a double‐blind placebo‐controlled crossover design, participants with high perceived stress ( N = 42, M age = 43.8) were assessed at baseline (BL) and assigned to either the Placebo Watch (PW) or Wellness Watch (WW) condition for 2 weeks, and then 2 weeks in the alternate condition. Participants completed the following self‐report surveys of Perceived Stress Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Index, Food Craving Questionnaire, and Profile of Mood States, as well as the CNS Vital Signs neurocognitive test at BL and following each condition. Results The WW condition had significant improvements in sleep duration and Complex Attention compared to the PW group. Compared to BL, both conditions had significant improvements for perceived stress, food cravings, mood, sleep quality, and several cognitive tests, p 's < .05. Conclusion Despite the placebo effect, NFT ® may be a natural alterative for improving stress and health. Research is needed examining the efficacy of NFT ® in a variety of populations and environments.
