Melatonin levels rise dramatically in the evening, and the hormone works to relax your body and mind, preparing you to fall asleep.
The study found that 70 percent of participants experienced a reduction in cortisol after exposure to binaural beats. Too-high cortisol levels are associated with insomnia, as well as more time spent in light sleep, rather than deep sleep. Cortisol levels rise and fall in connection to circadian rhythms-cortisol levels rise to their peak levels first thing in the morning, just in time for you to be active for the day. The study found that 68 percent of participants had increases to DHEA after using binaural beats. Particularly significant for sleep is that DHEA works to suppress cortisol, a hormone that stimulates alertness and provokes stress at elevated levels.
DHEA is critical to immune function and disease protection. DHEA functions as a kind of master hormone, helping to produce other hormones in the body on an as-needed basis.
