Sleep is an indispensable action and its importance has been related in many proverbs such as “the early bird catches the worm” However, there are few scientific reports on the effects of early rising.
In Mayumi Watanabe’s research review from Department of Medical Informatics, Niigata University published in Natural Science 2013 vol.5 by Scientific Research Publishing(View Original Post, please click here). Her team compared the following four groups: early risers with short sleep (Group E-S); early risers with long sleep (Group E-L); late risers with short sleep (Group L-S); and late risers with long sleep (Group L-L) Then the number and ratio of leukocytes, body temperature, glucose and its associated hormones were studied. Compared with Groups E-S and L-S, Groups E-L and L-L showed lower glucose and cortisol levels, respectively. The results indicated that early rising might affect leukocyte subsets, and adequate duration of sleep could decrease levels of glucose via modification of the autonomic nervous system.Thus early rising with adequate sleep could be expected as anti-aging effects.
Thus, the early bird can actually catch the worm with the effects of anti-aging because early rising might affect leukocyte subsets and adequate duration of sleep and could decrease levels of glucose via modification of the ANS. To maintain adequate sleep duration, going to bed early was needed. In cases in which persons stayed up late, efforts and ingenuity to get additional longer sleep duration were necessary.
