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:
“It is impossible, as impossible as to raise the dead, to restore anything that has ever been great or beautiful in architecture. That which I have ... insisted upon as the life of the whole, that spirit which is given only by the hand and eye of the workman, can never be recalled.”
—John Ruskin (1819–1900)
“You waves, though you dance by my feet like children at play,
Though you glow and you glance, though you purr and you dart;
In the Junes that were warmer than these are, the waves were more gay,
When I was a boy with never a crack in my heart.”
—William Butler Yeats (1865–1939)
