Excessive stress and sleep deprivation can cause cardiovascular issues, such as high blood pressure and heart disease. In a study focusing on the impacts of chronic stress on the heart, it was found that during times of chronic stress, the body hyperactivates the sympathetic nervous system which leads to changes in heart rate variability.

NREM Stage 1 (N1 – light sleep, somnolence, drowsy sleep – 5–10% of total sleep in adults): This is a stage of sleep that usually occurs between sleep and wakefulness, and sometimes occurs between periods of deeper sleep and periods of REM. The muscles are active, and the eyes roll slowly, opening and closing moderately.
Sleep deprivation slows the generation of facial reactions in response to emotional faces. [15] One to two nights of sleep loss in healthy adults is associated with a decrease in the generated intensity of positive moods (i.e. happiness and activation), as well as an increase in the generated intensity of negative moods (i.e. anger, depression ...
Although lyric gives depth and meaning to the music, it also stimulates cognitive processes, making it more difficult to fall asleep. Whereas instrumental music focuses on the melody and rhythm, it allows for relaxation without the distraction of lyrics. Research has given evidence for the use of instrumental music in improving sleep quality. [27]
REM sleep deprivation causes an increase in noradrenaline (which incidentally causes the person sleep deprived to be stressed) due to the neurons in the locus coeruleus producing it not ceasing to do so, which causes an increase in the activity of the Na⁺/K⁺-ATPase pump, which itself activates the intrinsic pathway of apoptosis [41] and ...
Electroencephalography has been used for meditation research.. The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as functional magnetic resonance imaging and electroencephalography, which are able to observe brain physiology and neural activity in living subjects ...
Studies have found that as little as 36 hours of sleep deprivation can cause a performance reduction in tasks requiring these executive functions. [27] Frontal lobe. The processes above illustrate a model of controlled versus automatic behavior that was hypothesized by Shallice et al. (1989), called the supervisory attentional system.
