Harvard Fatigue Laboratory (1927–1947) was a research centre designed to investigate the physiological, sociological and psychological impacts of fatigue caused by daily activities, and those on the conditions that industry workers faced at the time.
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection).
Woman experiencing stress. Employees who work overtime hours experience numerous mental, physical, and social effects. In a landmark study, the World Health Organization and the International Labour Organization estimated that over 745,000 people died from ischemic heart disease or stroke in 2016 as a result of having worked 55 hours or more per week.

Current: The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed , high voltage is an indirect risk for producing higher currents. Duration: The longer the shock duration, the more likely it is lethal—safety switches may limit time of current flow.
Perseverative cognition also focuses on the effects that worrying over anticipated events have on the physical body and mind. [2] This could suggest that obsessive worrying over past events or the future could lead to physical issues. There are some physical evidences of the effects of perseverative cognition, as noted in an analysis article. [7]
The largest contribution to the allostatic load is the effect of stress on the brain. Allostasis is the system which helps to achieve homeostasis. [18] Homeostasis is the regulation of physiological processes, whereby systems in the body respond to the state of the body and to the external environment. [18]
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] ...
Endothelin functions through activation of two G protein-coupled receptors, endothelin A and endothelin B receptor (ETA and ETB, respectively). [2] These two subtypes of endothelin receptor are distinguished in the laboratory by the order of their affinity for the three endothelin peptides: the ETA receptor is selective for ET-1, whereas the ETB receptor has the same affinity for all three ET ...
