To detect differences in the robustness of disruption strains to environmental stress we measured the growth rate of each strain in each of fifteen stressful environments (Materials and Methods) (figure 2).
Several studies have shown that stressful social and material conditions account for a large proportion of mental distress.
In this stressful context, intracellular material is degraded and the resulting breakdown products are released into the cytoplasm to be used by cell metabolism [ 4].
The authors emphasize the role of 'daily stressors' (stressful social and material conditions, ongoing adversity, or ecological stressors [ 50]), which directly and indirectly, influence the mental health.
The decreased impact of traumatic events on health outcomes and the larger magnitude of perceived needs on health outcomes is an added support for the negative influence of stressful social and material conditions on conflict-affected populations.
The negative effect of traumatic events on mental health and level of functioning in war-affected populations are well documented. 1 2 The role of stressful social and material conditions, besides the direct exposure to war-related traumatic events, has gained attention in recent years.
Interestingly, we observed relatively higher variance in the more stressful temperature (25°C, electronic supplementary material, table S1).
Additionally, many students found it stressful to be tested on new material on the same day.
Other items demonstrating significant negative associations with QOL included age, female gender, earthquake related material loss, number of stressful life events and number of reported physical illnesses.
Losing all that material and creativity is very stressful".
