Summary Introduction

To derive: A hypothesis to explain the effect of ice-cold water on the rate at which our body returns back to its normal temperature and also test this hypothesis.

Introduction: The temperature of body rises when someone comes after a long run. Homeostasis is operating under such circumstances for the regulation of temperature in the body. Hypothalamus of the brain maintains the temperature of the body. Homeostasis is mainly dependent on the negative feedback mechanism. When the temperature of the body rises, the hypothalamus senses the increase and reduces body tempearature by activating cooling mechanisms. For example, the secretion of sweat is a cooling mechanism.
