Fire, a natural phenomenon man has learned to control, plays a significant role in human health. Nature has designed the human system to eat cooked food. It is essential that, except for some greens which are ideally eaten raw, we cook all our food over fire properly and consume when they are freshly cooked. Stale food is prone to infection and should be avoided at all costs. Fire, besides being the principal agent of cooking, helps preserve human health by the warmth it offers to protect us from cold weather and the light that it emits to keep darkness away at night. Fire is also the most common sterilizing agent known to man and a phenomenon like no other that aids human comfort. The brightness of the light from fire invariably lifts a person’s spirits, aiding in mental health.
