Alcohol use disorder can vary in severity. Alcohol dependence can impact stress and other disorders in many ways. [70] For example, stress-related disorders such as anxiety and PTSD are known to increase risk of alcohol use disorder (AUD), and they are often co-morbid. Mental disorders that pair with AUD can impacts the brain in many ways.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.
Stress appears to play a role in hypertension, and may further predispose people to other conditions associated with hypertension. [48] Stress may precipitate abuse of drugs and/or alcohol. [5] Stress may also contribute to aging and chronic diseases in aging, such as depression and metabolic disorders. [49]
It causes a distinctive set of symptoms including aches and pains, rapid heartbeat, elevated blood pressure, sweating, palpitations, anxiety, headache, paleness, and a drop in blood glucose. If sympathetic activity is elevated for an extended time, it can cause weight loss and other stress-related body changes.
Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness. It can also cause mucosal erosions and superficial hemorrhages in patients who are critically ill, or in those who are under extreme physiologic stress, causing blood ...
Similarly, the process of allostasis becomes less efficient at managing the body's resources when the body endures increased levels of unhealthy stress due to wear and tear on the body and the brain. [16] An increase in allostatic load can impair and reduce neuroplasticity as stress causes the brain to age quicker. This is because with more ...
Cellular stress response is the wide range of molecular changes that cells undergo in response to environmental stressors, including extremes of temperature, exposure to toxins, and mechanical damage. Cellular stress responses can also be caused by some viral infections. [1]
