According to a measuring method or a control method of life activity, a life object is illuminated with an electromagnetic wave including a wavelength in a designated waveband, and a characteristic in a local area of the life object is detected, or a life activity thereof is controlled. This "local area" is an area constituted by one or more cells. The "designated waveband" is defined based on any one of the following phenomena: [1] transition energy between a ground state of a vibration mode newly occurring between atoms in a constituent molecule of a cell membrane and a plurality of excited states [2] transition energy between vibration modes occurring between specific atoms in a molecule corresponding to the activity of the life object or the change thereof and [3] a specific chemical shift value in Nuclear Magnetic Resonance.根據生命活力測量方法或控制方法,以包括指定波帶中的波長之電磁波照射生命體,及測定該生命體的局部區域中之特性,或者控制其生命活力。此“局部區域”為由一或更多個細胞所構成之區域。該“指定波帶”係依據下面現象的任一個所界定:[1]重新出現在細胞膜之組成分子中的原子之間的振動模式之基態與複數個激發態之間的躍遷能;[2]出現在對應於該生命體的該活力或其該變化之分子中的特定原子之間的振動模式之間的躍遷能;以及[3]核磁共振中的特定化學位移值。
