This work aims at determining the incidence of circadian daily variations of natural death at a general hospital. METHODS: We have analyzed time of death in 502 individuals with natural death. Statistical analyses have been applied to determine the difference significance between proportions and averages. As a result, we have found out that the occurrence of natural death was similar in different periods of the day. However, values indicate an excess of lethality at 6 a.m. and from noon to 6 p.m.. We have concluded that the observed results suggested that the natural death does not have a circadian pattern, despite the vespertine peak.
