In a study of 92
primary / elementary school aged children, Mr Coussens measured more than 30 different sleep parameters, such as
muscle movements,
breathing, eye activity and changes in the brain's processing.
• widespread effects on circulation,
muscles and sugar metabolism • raised heart rate • increased heart output • increased rate and depth of
breathing • increased metabolic rate • increased force of muscular contraction • delayed muscular fatigue • reduced blood flow to bladder (muscular walls relax and sphincters contract) • reduced blood flow to intestines • increased blood pressure • increased sugar (glucose) in the blood • increased break - down of glucose for energy *, especially in
muscle cells • increased free fatty acids in the blood * • more oxidation of fatty acids to produce energy * • more ATP (the cells»
primary energy compound) produced * • blood vessels constrict
