At Last Outdoor Sleepers Can Keep Heads Warm
OUTDOOR sleeping is likely to be more popular with the use of a newly designed electrically heated pad to keep the scalp warm; forâ€”particularly in the damp air and changing temperatures of springâ€”it is sometimes difficult to sleep comfortably without putting the head under the bedclothes. This, of course, defeats the purpose of sleeping outdoors.
To fill this need, the new electric pad is shaped for the head and designed so that the temperature never rises enough to injure the hair. The connection cord is attached to any electric-light socket.
