The Claim
Chronic circadian disruption, such as from repeated jet lag or constant light exposure, induces hypercortisolism and blunts acute stress responses in rodents, which is associated with metabolic dysfunction, mood disorders, and accelerated aging, suggesting that circadian misalignment acts as a physiological stressor.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When animals like mice or rats have their sleep-wake cycles messed up for a long time—like from constant light or frequent time zone changes—it messes up their stress hormones, makes them less able to handle sudden stress, and leads to problems like weight gain, mood issues, and aging faster.

What the research says
1 studyStudy: Interaction between circadian rhythms and stress
This study explains how our body’s internal clock controls stress hormones, and when the clock gets messed up—like from jet lag—it can cause too much stress hormone or make the body less able to handle stress, which harms health over time.
