Children need caring and supportive adults to help them because it is difficult for children to handle this type of stress on their own. [4] Therefore, the stress response may be activated from weeks to months or even years. [4] Prolonged stress leads to adverse effects such as permanent emotional or developmental damage. [4]
Stress proteins can exhibit widely varied functions within a cell- both during normal life processes and in response to stress. For example, studies in Drosophila have indicated that when DNA encoding certain stress proteins exhibit mutation defects, the resulting cells have impaired or lost abilities such as normal mitotic division and ...
In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
Heat shock proteins (HSPs) are a family of proteins produced by cells in response to exposure to stressful conditions. They were first described in relation to heat shock, [1] but are now known to also be expressed during other stresses including exposure to cold, [2] UV light [3] and during wound healing or tissue remodeling.

With strong roots in humanism, low arousal approaches have a philosophy of non-confrontation and 'do no harm'. In situations which may be stressful, responses that reduce levels of physiological arousal and stress are adopted by carers and staff, especially when supporting distressed individuals, who are more likely to perceive situations as stressful or threatening.
Stress activates this axis and produces neuro-biological changes. These chemical changes increase the chances of survival by bringing the physiological system back to homeostasis. [13] The autonomic nervous system controls all automatic functions in the body and contains two subsections within it that aid the response to an acute stress reaction.
The stress induced during exercise results in an increase in the hormones, epinephrine and norepinephrine, which are known for the body's "fight or flight" response. Increased secretion of catecholamines are a hormone response regulated by the sympathoadrenal system (SAS) and the hypothalamic-pituitary-adrenal axis (HPAA). [ 10 ]
Schematic overview of the classes of stresses in plants Neurohormonal response to stress. Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [2]
