- Covering your hands with GripRest and donning socks can induce a more rapid onset of sleep.
A clinical study by Kurt Krauchi and Anna Wirz-Justice (Psychiatric University Clinic, Basel, Switzerland) concludes warming of the palms and soles of the feet induces induces a more rapid onset of sleep.
According to the study a process identified as vasodilation occurs as the body attempts to redistribute the body's heat from the core to the extremeties.
Covering the extremeties creates warmth and can fool the body into a sleep receptive mode.
In addition to keeping the hands warm, Grip-Rest can induce relaxation of the forearm muscles, and after a short period of time 'habituation' causes one to lose track of any sensation in their fingers, and whether the fingers are curled or straight. This can occur is as little as five minutes, and is consistant with a relaxation state.
