emotional affect: e.g., anger, fear. [4] Some homeostatic feelings motivate specific behavior aimed at maintaining the body in its ideal state. For example, hunger motivates eating, fatigue motivates resting and hyperthermia motivates stepping into the shade. [5] [6] [7] Sheep respond to hunger, fatigue and hyperthermia by grazing and resting ...
Muscle fatigue is when muscles that were initially generating a normal amount of force, then experience a declining ability to generate force. It can be a result of vigorous exercise , but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction .
Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.
It's not just you: hot weather really does make you lazy and less productive -- and there's a simple scientific explanation for why that is so.
Examples of edema in specific organs: Peripheral edema ("dependent" edema of legs) is extracellular fluid accumulation in the lower extremities caused by the effects of gravity, and occurs when fluid pools in the lower parts of the body, including the feet, legs, or hands.
The human body always works to remain in homeostasis. 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.
Fatigue is a state of tiredness (which is not sleepiness), exhaustion [1] or loss of energy. [2] [3]Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states.

Anti-fatigue matting is recommended and launderable matting is preferred. [ citation needed ] A study investigating the effects of 4 different standing conditions on assembly workers showed that using mats and shoes with in-soles was perceived as more comfortable for the workers than without while standing on hard floors.
