A researcher proved this in a round about way as he/she was trying to prove lack of sleep won’t kill you. He kept animals awake until they died, then autopsied them. His results stated:
“Another rare disorder, Fatal Familial Insomnia (FFI), is an autosomal dominate disease that is invariably fatal after 6-30 months without sleep. FFI is probably misnamed because Death resulted from multiple organ failure rather than sleep deprivation.”
If by withholding sleep, death resulted from organ failure, then sleep is necessary for the health of our organs without which we die! We are human animals. This research proved most of my observations on sleep over the last 15 years. Sleep is most important for our health and affects all our every day activities.
From our health, family problems, work problems and how we deal with living, all are affected by how well we sleep not by how long.
