Hypothesis
Sleep has evolved to protect animals from parasitic infection.
Conclusion
Mammalian species that sleep longer are better protected from parasitic infections due to enhanced immune system investment.
Supporting Evidence
- Longer sleep durations are associated with higher white blood cell counts.
- Mammals that sleep more have fewer parasites.
- Increased sleep correlates with enhanced immune system investment.
Takeaway
Animals that sleep more can fight off germs better, which helps them stay healthy.
Methodology
Comparative analyses of mammalian sleep, immune system parameters, and parasitism were conducted.
Potential Biases
Potential overestimation of sleep durations in captive animals compared to wild settings.
Limitations
The study relies on data from published literature, which may not fully represent wild sleeping behaviors.
Participant Demographics
Data were collected from 26 different mammalian species.
