Sleep patterns are affected by behavioral and emotional disorders, and aspects of emotional and cognitive well-being are influenced by sleep patterns. [21] Scientists have examined the effects of deficient sleep patterns on emotion regulation in individuals diagnosed with mental disorders ( e.g. depression and anxiety ), [ 22 ] borderline ...
Sleeping Girl, Domenico Fetti, c. 1615 . Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain sensory activity is inhibited. . During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environm
This is particularly apparent in the right hemisphere. In non-sleep-deprived people involved in verbal learning and arithmetic tasks, the anterior cingulate cortex and the right prefrontal cortex are active. Following sleep deprivation, there is increased activation of the left inferior frontal gyrus and the bilateral parietal lobes. This ...
Sleep plays a role in emotion regulation, although stress and worry can also interfere with sleep. Studies have shown that sleep, specifically REM sleep , down-regulates reactivity of the amygdala , a brain structure known to be involved in the processing of emotions, in response to previous emotional experiences.

Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity, and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep, [1] and reduced interactions with surroundings. [2]
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal, particularly from negative sources such as anger, anxiety, or fear. [2] Relaxation is a form of mild ecstasy coming from the frontal lobe of the brain in which the backward cortex sends signals to the frontal cortex via a mild sedative.
People seem to experience a positive mood when they have a clean slate, have had a good night sleep, and feel no sense of stress in their life. There have been many studies done on the effect of positive emotion on the cognitive mind and there is speculation that positive mood can affect our minds in good or bad ways.
