Due, no doubt to wrong life, man's senses are comparatively dulled. In all cases of fasting the senses become more acute. So invariable and distinctive is this that Hygienists have long regarded it as more or less certain evidence that the patient is fasting. Professor Morgulis says that "the acuity of the senses is increased by fasting" and that at the end of his thirty-one days abstinence from food "Levanzin could see twice as far as he did at the beginning of the fast."

The acuteness of perception is most marked in fasting cases. Many users of glasses are enabled to discard their glasses and see as well as ever without them. I have had one complete recovery from complete blindness in one eye while fasting. Invariably the eyes become clear and bright.

There are occasional fasters in whom, towards the end of a very prolonged fast, vision grows dim and coordination of their eyes is impaired. They see double, see spots floating before their eyes, and are unable to read. This is a temporary weakness that disappears after the fast is broken. I have never seen any permanent injury follow in these relatively rare cases, but have seen distinct and permanent improvement in vision follow. People who, before the fast were unable to get along without glasses, have been able to discontinue their use, after recovering from this temporary weakness.

The sense of touch is invariably sharpened. It is not easy to determine the state of the sense of taste during the fast, but the patient invariably discovers that his sense of taste is more acute and discriminating following the fast than before the fast.

The improvement in the sense of hearing is, commonly, even more marked than that of the other special senses. No doubt part of this improvement in the sense of hearing results from the clearing of catarrhal conditions in the ears and eustachian tubes. Part of it is the result of the general rise in nervous condition. Although no one makes the claim that all deaf and near-deaf individuals can regain their hearing by fasting, it is, nonetheless, a fact that many deaf people have so regained their hearing. I had one patient who had been completely deaf in one ear for twenty-five years who regained her hearing in thirty days of fasting and was able to hear her watch tick at arm's length with her formerly deaf ear. It should be understood that spectacular results, such as the recovery of sight by the blind and recovery of hearing by the deaf are not to be expected as a regular result of physiologic rest.

The sense of smell is invariably sharpened, often as a result of the disappearance of nasal catarrh, but even in those cases where there is no catarrh of the nose, the sense of smell becomes very acute. Indeed, its acuteness is often so marked as to be a source of discomfort due to the fact that the faster smells disagreeable odors in his environment that were not detected before the fast. On the other hand he derives added pleasure from smelling agreeable odors.

The following is from a letter from John W. Armstrong which was published in the Yorkshire (England) Evening Post, January 16, 1933, and illustrates not merely the heightened acuteness of the sense of smell produced by fasting, but also the strength and endurance an animal may have after fourteen days without food.

"Shortly before the war a discussion between Russian professors of medicine and a body of physical culturists resulted in an acid test being made of the respective fitness and sensitivities of well-fed and "starving" (?) bodies. Wolves were chosen for this test, 36 animals being kept in a pit where a stream of fresh running water was diverted to run through and a similar number of the untamed creatures placed in a second pit and fed every day on fresh raw meat and water.

"For 36 hours the unfed wolves were restless and snappy, then, appearing to accept the inevitable, the pack grew quiet and lazy. Until the tenth day they proved the assertions of the Naturopaths that the body never feeds so calmly and easily as when feeding upon its own tissues, by sleeping most of the time. Towards the 14th day they began to grow fierce and super active, having lost all their flesh (the healthy flesh formed of natural food in the wilds in outdoor creatures melts readily and quickly under the internal heat engendered by the process of fasting--thrice as quickly as flesh formed from civilized cooked and prepared food).

"The wolves had reached that stage where fasting is approaching its end and natural hunger is setting in, a stage at which food must be given.

"Released on the 15th day with a herd of deer many miles beyond them and to windward of both packs the unfed pack took scent first, set up the chase and when overtaken by fleet motor-cars, had caught up with their prey and dined off the killed deer, leaving nothing but the bones.

"I leave the reader to judge what this proves, but would add, in passing, the findings of many experienced observers that fasting invariably restores, if conducted long enough, the sense of sight, hearing, smell, taste and touch, and also the gift of speech when lost as in seizures, shock, etc."

I do not agree that fasting will invariably restore sight, hearing, smell, etc., but that it frequently does so is not a matter of doubt.

There can be no doubt that all of man's special senses are more or less dulled or weakened by civilized life and by his "disease" and degeneracy. In fasting, without the recorded exception of a single case, the senses are remarkably improved. Indeed, so distinctive a sign is this that we look upon it as evidence that our patient is fasting. I have seen hearing restored on a fast. Catarrhal deafness of long standing, where there are no adhesions in the eustachian tube, is always improved or overcome. Hearing in those who consider their hearing normal becomes so acute that sounds that ordinarily are never heard are noticed often to the extent that the faster is annoyed by them. People who have been deaf for years are enabled to hear the ticking of a watch and low sounds that before was impossible. I have seen the senses of taste and smell, which had long been paralyzed, restored to their normal condition while fasting. The sense of smell becomes so acute that the faster is often annoyed by odors in his daily environment that he never before knew existed. People who have worn glasses for years and who could not read without them are frequently enabled by a fast to discard their glasses and find their sight to be as good as ever. The eyes also become clear and bright. The sense of touch becomes very acute.

The weakening and deadening of man's sense perceptions is due chiefly to depleted vitality and the accumulation in the tissues of excess food and retained waste matter. The fast by cleaning out the excesses and wastes and eliminating them from the system and also by permitting nervous recuperation, removes the causes of dulled senses.
