Sleep is regulated by your circadian rhythm, or body clock, located in the brain.睡眠由脑内的昼夜节律或生理时钟所管理。The body clock responds to light cues, ramping up production of the hormone melatonin at night and switching it off when it senses light.生理时钟对光信号有所反应，在夜晚会...

Sleep is an altered physiological state characterized by a unique state of consciousness, decreased sensory awareness, and lower reactivity to stimuli.
The Science Behind Sleep Syncing Ourcircadian rhythm is primarily regulated by a group of nerve cells in the hypothalamus, called the suprachiasmatic nucleus (SCN). The SCN receives input from the retina, which detects light and dark cycles in our environment, and sends signals to other parts of...
Human sleep is regulated by light in two fundamental ways: The light-dark (LD) cycle entrains a circadian clock that in turn regulates sleep timing, and light per se can acutely inhibit sleep. Throughout evolution, these sleep regulatory systems became highly sensitive to the effects of light...
This is the deepest phase of NREM sleep and the most beneficial to overall wellbeing as, during this phase the body works on rejuvenation. Stage three of NREM sleep is characterised by slower breathing and heartbeat leading to a lower blood pressure. The heart provides more blood to relaxed ...
