The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...
Traffic noise has several negative effects, including increased risk for coronary artery disease, with night-time exposure to noise possibly more harmful than day-time exposure. [2] It has also been shown to increase blood pressure in individuals within the surrounding residential areas, with railways causing the greatest cardiovascular effects.
One early study into neurochemical influences on sleep and memory was conducted with cats and demonstrated that sleep deprivation increased brain protein synthesis. There is evidence that these altered levels of proteins could increase the excitability of the central nervous system, thus increasing the susceptibility of the brain to other ...
This will eliminate external information and sensory distractions such as white noise and other information presented in an environment. Finally, it is important to make consuming a pleasant and relaxed experience. [32] This will help diminish the stress, overwhelming feeling, and experience of sensory overload.
Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. Sleep apnea impacts brain in ways that may ...
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
Irregular sleep schedules can cause negative impacts on learning, memory, and performance. The dual process theory determines that certain types of memory depend on specific sleep states, like REM and NREM (Non-Rem) states. REM sleep deprivation can reduce sleep-induced improvement such as visual perception, thus influencing how one learns.
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 ...
