Hand warmers are small (mostly disposable) packets which are held in the hand and produce heat on demand to warm cold hands. They are commonly used in outdoor activities such as hiking and skiing to keep extremities warm and assist insulated clothing. Other types of warmers are available to provide soothing heat for muscular or joint aches.
Depending on the type and the source of heat, hand warmers can last between 30 minutes (recrystallisation) to 24 hours (platinum catalyst).
Famous quotes containing the words hand and/or warmer:
“His leanings were strictly lyrical, descriptions of nature and emotions came to him with surprising facility, but on the other hand he had a lot of trouble with routine items, such as, for instance, the opening and closing of doors, or shaking hands when there were numerous characters in a room, and one person or two persons saluted many people.”
—Vladimir Nabokov (1899–1977)
“Sentimentalists ... adopt whatever merit is in good repute, and almost make it hateful with their praise. The warmer their expressions, the colder we feel.... Cure the drunkard, heal the insane, mollify the homicide, civilize the Pawnee, but what lessons can be devised for the debauchee of sentiment?”
—Ralph Waldo Emerson (1803–1882)
