Hypothalamus

The Temperature Regulator

Whether you're trying to keep from freezing at the North Pole or sweating your way across the Sahara; whether you're in bed or running for the bus — your body temperature, if you're healthy, remains about the same — 37 o C (98.6 F). If the temperature varies a few degrees up or down, it indicates illness and calls for medical treatment.
How does the body maintain this temperature in all seasons and at all places?
The hypothalamus, a tiny bundle of nerve cells in the centre of your brain plays a major role in this remarkable feat. If your body temperature shows signs of rising, the hypothalamus gets your body to sweat. As the sweat evaporates, it cools the body.
If on the other hand your body temperature is dropping, the hypothalamus gets your body's sweat glands to shut down and makes you shiver. Shivering involves the use of various muscles and this produces heat in the body.

Dimdima is the Sanskrit word for ‘drumbeat’. In olden days, victory in battle was heralded by the beat of drums or any important news to be conveyed to the people used to be accompanied with drumbeats.
