Calcium has been considered good for our bones, but it might also be good for good night's sleep, a research has said.
It has showed that sleep depends on activity of calcium inside neurons.
Study has also revealed that a mechanism regulated by calcium ions is responsible for controlling sleep duration.
Research, published in ‘Neuron’ journal, contributes to treatment of sleep disorders like sleep apnea and insomania and other associated neuro-degenerative diseases.
Over a life time the amount of sleep needed gets gradually reduced, in both animals and humans.
Sleep allows the body to recover from the effects of daily life, such as removing waste products from the brain and restoring the immune system, and may use the time to process experiences and lay down long-term memories.
"Although sleep is a fundamental physiologic function, its mechanism is still a mystery," said author Hiroki Ueda from the University of Tokyo in Japan.
Team developed a computational model of sleep and identified seven genes responsible for causing mice to stay awake or fall asleep.
Research group then tested their forecasts against 21 different genetically modified mouse types.
Out of the 21, seven exhibited important changes in sleep duration.
In addition, the research group also showed that the inflow of calcium ions into neurons is required for mice to fall asleep and that pumping calcium ions out of neurons is required for mice to wake up.
