Write an essay on "Sleep"

A. The necessity for sleep is obvious, for thereby man gives rest to his tired brain, restores the vigour of this body, and fits himself once more for the labours of the coming day. It is a gentle consoler, often having the power to drive away the sorrows of the wretched and banish the pain of those who lie in torture upon a bed of sickness. Though universally beloved as a great blessing, it is a mysterious thing. In moments of thoughtfulness, it is impossible to reflect without surprise that man resigns himself to sleep so carelessly and cheerfully. He enters a state of oblivion from which he may never awake, and deliberately loses consciousness of his surroundings, though knowing that he is deaf to any danger that may approach. Most pitiable is the condition of those who are unable to sleep, whether the inability comes from physical pain which will not allow the body to rest, or from sorrow or remorse which banishes from the mind its natural healer. Pain indeed is one of the most common causes of sleeplessness. Excessive fatigue, or idleness, also will often cause long and dreary nights, and only those who have suffered thus, can realise with what intense impatience the coming of the dawn is awaited. The injuries that sleeplessness is responsible for, are many and far-reaching in their effects. When mind and body cannot rest, they cannot recuperate or restore their shattered energies. They grow feebler and feebler, until at length the mind ceases to perform its functions and the man becomes mad. The body is not so quickly affected, but continuous absence of sleep will gradually take away and finally destroy its power. A healthy man does not suffer from this evil. It is necessary, therefore, to keep body and mind sound and healthy. They should both be made to work, the harder the better, so long as they are not subjected to over-fatigue. Only wholesome food should be eaten, and that in moderation. Rational amusements should be cultivated, which will chase away worry and trouble and prevent unnecessary brooding. Vice and over- indulgence in any form should be avoided, and all important is the maintenance of regular habits.
