Buhr et Al

• Additionally, it has been suggested that temperature may be more important than light in determining circadian rhythms.
• Buhr et al. (2010) found that fluctuations in temperature set the timing of cells in the body and caused tissues and organs to become active or inactive. Buhr claimed that information about light levels is transformed into neural messages that set the body’s temperature.
• Body temperature fluctuates on a 24-hour circadian rhythm and even small changes in it can send a powerful signal to our body clocks.
• This shows that circadian rhythms are controlled and affected by several different factors, and suggests that a more holistic approach to research might be preferable
