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:
“That big gun in your hand makes you look grown up—you think! I’ll bet you spend hours posing in front of a mirror holding it, trying to look tough!... You scum!”
—Richard Brooks (1912–1992)
“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)
