    The decrease in systolic blood pressure, diastolic blood pressure, and heart rate signal a state of calmness, which is essential for having a good night sleep. Sedative music, which is characterized by a slow tempo, repetitive rhythm, gentle contours, and strings, is effective in generating anxiolytic responses to aid sleep.

  3. Brainwave entrainment - Wikipedia

    en.wikipedia.org/wiki/Brainwave_entrainment

    Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...

  4. Beat (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Beat_(acoustics)

    In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized.

    A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 30 and 100 Hz, the 40 Hz point being of particular interest. [1] Gamma rhythms are correlated with large-scale brain network activity and cognitive phenomena such as working memory , attention , and perceptual grouping , and can be increased in ...

    Sleep apnea is an under-recognized risk factor for heart failure. Uncontrolled sleep apnea may increase the risk of heart failure by up to 140%. [4] Weight reduction – through physical activity and dietary modification, as obesity is a risk factor for heart failure and left ventricular hypertrophy. Effective weight management has been shown ...

    The response rate to sleep deprivation is generally agreed to be approximately 40-60%. A 2017 meta-analysis of 66 sleep studies with partial or total sleep deprivation in the treatment of depression found that the overall response rate (immediate relief of symptoms) to total sleep deprivation was 50.4% of individuals, and the response rate to partial sleep deprivation was 53.1% [3] In 2009, a ...
