<P>PROBLEM TO BE SOLVED: To provide a sleep meter and sleep condition determination method that enables the observation of sleep conditions in an easy way. <P>SOLUTION: The sleep meter includes a frequency analysis means to analyze and extract the frequency components of δ, α, σ and β waves of brain waves detected from a living body, and a sleep conditions determination means to determine the sleep conditions per prescribed time block from the contents and content ratios of the frequency components of δ, α, σ and β waves of brain waves. The sleep condition determination method includes the step of analyzing the frequencies of brain waves detected from the living body and extract the frequency components of δ, α, σ and β waves thereof, and another step of determining sleep conditions per prescribed time block from the contents and content ratios of δ, α, σ and β waves of the brain waves. <P>COPYRIGHT: (C)2009,JPO&INPIT |
