THERMAL HOMEOSTASIS

This text explores the process of thermoregulation in homeostasis, focusing on heat production and loss. Topics include the control center in the hypothalamus, effectors, body temperature disturbances, and the effects of heat and cold applications. It also discusses different constitutional types and their predispositions to certain health issues.

Presentation Transcript

  1. THERMAL HOMEOSTASIS HEAT PRODUCTION = HEAT LOSS Chemical heat reg. physical heat reg. • Homeotherms are very sensitive to thermal stimuli • Thermal regulaton takes precedence over metabolic processes • By influencing temp. reg. control in the hypothalamus > alterative effect

  2. THERMOREGULATION “Set point” 37C/98.6F Actual value Control centre hypothalamus Effectors – Vasoconstriction/dilation, adrenal medulla, thyroid, skeletal muscles, Sweatglands, pilomotor Receptors in skin & hypothalamus BODY TEMP DISTURBANCE IN STEADY STATE

  3. TEMPERATURES • Cold <18C • Cool 19-22C • Tepid 23-31C (non-therapeutic) • Indifferent 32-35C (skin temp. – start with this for rising temp baths) • Warm 36-38C • Hot 39-42C • Very hot 43-46C

  4. SHORT COLD APPLICATIONS • 1ary blood vessel contraction • 2ndary dilation both above via neurological vasomotor activity • Fall in blood temp. • Reduction in heart rate – can last 30 mins • 1ary sedation, 2ndary stim. of metabolism • Analgesia – esp. by rapid reduction of skin temp. • Reduces nerve conduction velocity • Reduces inflammation • Reduces oedema

  5. Short/Long cold

  6. HEAT & OVERHEATING • Increases body core temp. • Increases heart rate and cardiac output • Increases O2 demand • Increases metabolism • Reduces pain • Reduces muscle tension • Increases filtration, diffusion & phagocytosis

  7. Short/Long Hot

  8. Localised long hot by blitzguss

  9. Lymphatic Constitution.

  10. Predisposition to exudative processes, catarrh, rheumatism, disorders of the mucous membranes and skin. • Swollen glands indicate levels of toxic load. • Blood and bodily fluids can be thin. • Often states of dis-ease manifest and progress due to a stifled and congested lymphatic system.

  11. Lymphatic types commonly DO NOT LIKE COLD WATER APPLICATIONS BUT NEED THEM! • Short cold increases blood and lymphatic circulation and metabolism, generating warmth to the extemities • Increases detox processes

  12. Haematogenic Constitution

  13. Predisposition towards blood disorders, digestive system problems and slow metabolism. • Common disorders include cold extremities, digestive tract imbalances, venous blood stagnations, anaemias, high blood lipids, lithic formation and auto intoxications

  14. Blood and body fluids tend to be thick – often from nitrogenous and uric acid wastes. • Short hot applications thin blood, modestly improve blood circulation and metabolism. • Best administered by bath for hydrostatic pressure effect to encourage venous return and lymph flow.

  15. Biliary Constitution

  16. Predisposition towards gastrointestinal, liver, gall bladder and pancreatic problems. • Common symptoms include digestive tract problems, blood sugar fluctuations and increased lipid levels. • Blood and body fluids hold the middle ground.

  17. Assess constitutional leanings between haematogenic and lymphatic types • Application of packs to strategic areas where indicated • Haysack • Cold sock • Castor oil with wet heat • Washings • Arm & leg baths
