GOOD HEALTH 



When a room has to get its air from windows, there 

 is always danger from drafts. Now a draft is like a small 

 wind in a room, that is, we say there is a draft when the 

 air is moving fast enough for us to feel it. If a window 

 is open on each side of the room where you are sitting, 



and if you are be- 

 tween them, you are 

 probably in a draft, 

 and I am afraid you 

 will catch cold. 



It is curious, but 

 true, that it is easier 

 to catch cold in a 

 draft in a room than 

 in the wind out of 

 doors, even when 

 that wind is blowing 

 hard enough to break 

 the branches of trees. 

 The reason is that a draft is very uneven. It cools part 

 of the body at a time, and when this is the case the 

 machinery that regulates body temperature does not 

 work well. It does better when the whole body is warm 

 or the whole body cold than when it is warm in one 

 spot and cold in another. 



Perhaps the best way with windows is to open them 

 at the top. Then the air blows across the upper part of
