Is insomnia more of a physiological phenomenon or a psychological one?

Nobel laureate Michael YOUNG points out that genetic changes can lead to insomnia on the WLA Forum. "Different forms of insomnia may require different forms of treatment."

"Dietary proteins can suppress sensory responsiveness to promote deeper sleep." Though strongly influenced by genetics, deeper sleep requiring stronger sensory suppression can be consolidated by proteinaceous diets.
