Inactivity
Another trigger of nocturnal foot cramps can be inactivity. This cause is more common in those people who are physically inactive or often sit for an extended period of time at school or work. Without movements, blood flow cannot circulate properly to your feet and make them more susceptible to cramps. Having a poor posture would also cause nerve compression and increase the risk. Even your position when sleeping might affect nerve problems and blood circulation. Therefore, make sure to lead an active lifestyle and adjust your posture if necessary. [2]
