The Hygiene of Tobacco 307 



as far as possible from the eyes and nose. The longer 

 the pipe the better. The custom common in France 

 and Russia of passing the smoke through the nose is 

 very injurious, and frequently destroys the sense of 

 smell. The insidious habit of swallowing the smoke 

 is responsible for the stomach troubles from which 

 many cigarette-smokers suffer. 



To smoke when taking active exercise is bad — bad 

 for the exercise and bad for the smoke. Especially 

 does this apply to cycling. One may smoke a pipe 

 when cycling ; to puff a cigar when scorching is add- 

 ing insult to injury to the cigar ; a cigarette will blow 

 to pieces. Don't smoke when cycling ; one is com- 

 pensated for one's abstention by the rare delight of a 

 pipe at the journey's end. Smoking by soldiers on the 

 march increases the number of men who fall out. It 

 is more than worth while to abstain from smoking for 

 three or four hours in order to enjoy the delectation 

 of the subsequent smoke. 



There is one point that smokers should bear 

 in mind — that over-smoking is a common cause of 

 insomnia. To brain-workers smoking is at first a 

 sedative ; the second pipe acts as a powerful stimu- 

 lant. When used continuously tobacco thus becomes 

 a cerebral irritant, and the centres of the brain are 

 unable to adjust themselves to the condition required 

 for healthy sleep. From this indulgence in tobacco 

 immediately before retiring to rest insomnia frequently 

 arises. Those who smoke hard during the day should, 

 if suffering from insomnia, abstain from tobacco for 

 an hour before going to bed, or at all events curtail 

 their evening's tobacconalian revelry.
