Circadian rhythms of body temperature and activation and the well-being of older women

Area of Science:

• Gerontology
• Chronobiology
• Psychology

Background:

• Understanding circadian rhythms is crucial for assessing well-being in aging populations.
• Previous research suggests links between daily biological rhythms and psychological states.

Purpose of the Study:

• To investigate the relationship between circadian parameters of body temperature and activation and the general well-being of healthy older women.
• To determine if daily fluctuations in temperature and activation rhythms correlate with subjective well-being.

Main Methods:

• 18 healthy women aged 65-80 participated.
• Oral temperature and Activation-Deactivation Adjective Check List (AD ACL) data were collected every 2 hours over 7 days.
• General Well-Being Questionnaire was administered daily.

Main Results:

• Both body temperature and activation exhibited significant circadian periodicities.
• No statistically significant correlations were found between the parameters of these circadian rhythms and the subjects' reported well-being.

Conclusions:

• Circadian rhythms in body temperature and activation are present in healthy older women.
• These specific circadian parameters do not appear to directly influence or correlate with general well-being in this demographic.
