Surprising Findings
Fasting glucose and lipids didn’t change — but glucose tolerance did.
Most people think blood sugar problems show up in fasting tests, but this study found normal fasting levels even in stressed rats. The damage only showed up when sugar was introduced — revealing a hidden metabolic dysfunction.
Practical Takeaways
Do moderate aerobic exercise (like swimming or brisk walking) 5 days a week to build resilience against stress-related blood sugar problems.

Exercise can change how your body handles stress by rewiring the system that controls cortisol, the stress hormone.
Stressing out male rats every day for 12 weeks made their stress hormone levels more than double, showing the stress method really works.
Stressing out male lab rats for a long time makes their bodies worse at handling sugar, even though their resting blood sugar stays the same.
If male lab rats swim for an hour, five days a week for three months, they can swim much longer by the end — up to 2.7 times longer — which means their stamina and heart-lung fitness really improved.
Swimming helps lower stress hormone levels in stressed-out male rats, which might mean exercise can calm an overactive stress system.
