Sleep Deprivation
Muscle twitches and spasms might occur when you are sleep deprived. The brain communicates with the body through neurotransmitters. These brain chemicals can transmit information to different nerves and help control the contraction of muscles. Sleep deprivation might affect the operation of neurotransmitter receptors. Excess neurotransmitters might accumulate in your brain, which will be later sent to muscle fibers and cause a twitch or spasm. Therefore, it is important to sleep at least 7 to 9 hours per night. If you have any sleep issues, make sure to contact your doctor for proper treatments. [3]
