psychological stress may cause diseases such as ulcers and high blood pressure
Hans Selye is the psychologist credited with proposing the general adaptation syndrome. This theory describes the body's response to stress as progressing through three stages: alarm, resistance, and exhaustion. It has had a significant impact on understanding the physiological effects of stress.
During the resistance phase of the general adaptation syndrome, there is a high demand for glucose, especially by the nervous system. The hormones GH-RH and CRH increase the levels of GH and ACTH, respectively. Growth hormone mobilizes fat reserves and promotes the catabolism of protein; ACTH increases cortisol, which stimulates both the conversion of glycogen to glucose and the catabolism of fat and protein.
The first psychological response a person might notice in the alarm phase of the general adaptation syndrome is the body's fight-or-flight response, where adrenaline is released to prepare the body to face the perceived threat or stressor. This can lead to heightened awareness, increased heart rate, and a sense of urgency.
Sensory adaptation refers to the decreased response of sensory receptors to a constant stimulus, leading to reduced perception of that stimulus over time. Negative adaptation, on the other hand, involves a decrease in the overall response of a system to a stimulus due to prolonged exposure. While sensory adaptation is specific to sensory receptors, negative adaptation is a more general phenomenon that can occur across various systems in response to prolonged stimulation.
Life expectancy can vary for individuals with Robinow syndrome depending on the severity of their symptoms and associated complications. In general, most individuals with Robinow syndrome have a normal lifespan, but some may experience health issues that can affect their life expectancy. It is important for individuals with Robinow syndrome to receive regular medical monitoring and appropriate care to manage their condition.
General adaptation syndrome is used to describe how someone's body short and long term reaction to stress. This is to see how someone is able to handle their stress.

Dr. Hans Selye was the psychologist who discovered the General Adaptation Syndrome.
General adaptation syndrome, or GAS, is a term used to describe the body's short-term and long-term reactions to stress. There are three stages the alarm reaction, the stage of resistance, and the stage of exhaustion.
The hypothalamus and the sympathetic nervous system are primarily associated with the general adaptation syndrome. The hypothalamus initiates the stress response, while the sympathetic nervous system activates fight-or-flight reactions in response to stress.
