| Sleep reactivity is the trait-like degree to which stress exposure disrupts sleep, resulting in difficulty falling and staying asleep | The vertical line represents the standard error |
|---|---|
| On the other hand, cold exposure does not affect sleep stages, though the use of beddings and clothing during sleep is critical in supporting thermoregulation and sleep in cold exposure | These effects of the thermal environment on sleep stages are strongly linked to thermoregulation, which affects the mechanism regulating sleep |

| Sleep patterns and mortality among elderly patients in a geriatric hospital | However, cold exposure affects cardiac autonomic response during sleep without affecting sleep stages and subjective sensations |
Given that insomniacs with high sleep reactivity tend to present with severe insomnia phenotypes, patient sleep reactivity may inform triaging to different levels of treatment.
| Centers for Disease Control and Prevention | With the development of cost-effective assessment of sleep reactivity, we can now identify individuals at risk of future insomnia, shift-work disorder and mental illness, thus identifying a target population for preventive intervention |
|---|---|
| In semi-nude subjects, sleep stages are more affected by cold exposure than heat exposure | Sleep reactivity is most pathologically and clinically pertinent when in excess, such that high sleep reactivity predicts risk for future insomnia disorder, with early evidence suggesting high sleep reactivity corresponds to severe insomnia phenotypes sleep onset insomnia and short sleep insomnia |
