Oh I see. So the hypothesis is “In a healthy animal, stress is a highly-informative signal that inhibits risk-taking. Sleep ensures the stress system continues to inhibit risk taking appropriately.”
Makes sense. It’s consistent with sleep deprivation raising the level of cortisol and the brain developing a tolerance to high levels of certain hormones.

Yes, that’s a rough stretch of the idea. Of course, the real details are likely complicated.
It’s worth noting that Orexin does stimulate the hypothalamic-pituitary-adrenal (HPA) axis, which controls cortisol release.
