Biopsychology - Assignment ExampleAnother reason for peacefulness is that it serves as physiological main(prenominal)tenence. During sleep, muscles and other alter cellular components use the time to repair and regenerate. Another important feature of sleep physiology is the notion of an upcountry clock, or our natural circadian rhythms. Circadian rhythms are observed in almost all life story things. This internal clock serves as regulating when to be active and using energy compared when the organism should be resting to conserve energy. The cycle occurs once per day. In particular, the effect can be seen with the impact of the changing amongst daylight and nighttime. This can be seen by the effects of sleep and light on the secretion of received neurochemicals and hormones such as melatonin. Sleep occurs in distinct phases, which is characterized by a change in brainpower wave activity as well as some physiological changes. There are 2 main phases of sleep non- rapid eye mo vement and rapid eye movement. show 1 is characterized as the light sleep that is predominated by theta waves that lasts amongst 5-10 minutes. The second stage lasts around 20 minutes and sleep spindles begin to form, which are rapid bursts in brain activity. The third stage is characterized by delta waves and is in between light and heavy sleep. Stage four is deep sleep, which is again characterized by an increase in delta waves. Stage 5 is the deepest stage of sleep and this is where REM occurs. REM stands for rapid eye movement. The most vivid conceive of occurs during this stage of sleep because it is the deepest stage of sleep. REM usually occurs between 4 and 5 times throughout the entire night. The mind is extremely active during this period with levels of neurological activity creation similar to that of being awake.

Principally there are two main chemicals, which are mediated in stress responses. Cortisol and norepinephrine release are triggered when a person is experiencing a stressful situation. These chemicals function as a stimulus, which heightens physiological response to handle the incoming threat or danger. Stress has been linked to a multitude of physiological problems. Prolonged stress can melt down to sleep depriva tion and insomnia, which leads to a host of its own physiological problems. Increases in blood pressure and impetus can lead to heart disease and cancers. Stress can also affect the endocrine outline because too much stress leads to over activity in this system, which can lead to certain types of cancers as well as certain types of diabetes. Increased stress can also lead to compromising the resistant system, which can make a person more susceptible to developing infection and illnesses. It has also been shown that stress has a physiological
