+provides an understanding that when they are disrupted there are consequences
Study→night workers engaged in shift work experience
Period of reduced concentration around 6am (circadian trough→ mistakes more likely)
Relationship established between shift work and poor health→shift workers are 3x more likely to develop heart disease than ppl with normal day patterns
Shows real-world economic implications of how to best manage worker productivity
-studies investigating the effects of shift work tend to use correlational methods
Difficult to establish whether desynchronisation of sleep/wake cycle is actually a cause of observed negative effects
Solomon→high divorce rates in shift workers may due to strain of being awake at dif times from their family (unwise to assume it’s a consequence of biological rhythms)
+used to improve medical treatments
Circadian rhythms coordinate a no. Of bodies basic processes(heart rate/digestion)
Led to fiend of chronotherapeutics→medical treatment administered in way that corresponds to a person biological rhythms
Aspirin for treatment for heart attacks should be taken last thing at night→so timing of drug can be released during vulnerable period for heart attacks (early in morning)
-generalisations are difficult to make(small samples in studies used)
Siffre study→small sample of pps(not representative of whole population)
As research has shown that there are individual difference in circadian rhythms
Czeisler et al-individual SWC can vary from 13 to 65 hours
Duffy & Czeisler-
some ppl display a natural preference for going to bed early and rising early(larks)
Some ppl prefer go to bed late and wake up late (owls)
