Jet lag makes hamsters dumb

A new study highlights the perils of shifting time zones

SAN DIEGO — In addition to making you groggy and dazed, jet lag may make you stupid. A study presented November 15 at the annual Society for Neuroscience meeting finds that hamsters suffering extreme, chronic jet lag had about half the normal rate of new neuron birth in a part of the brain. What’s more, these animals showed deficits in learning and memory.

Jet lag poses a serious health threat, said study coauthor Erin Gibson of the University of California, Berkeley. Studies have shown that people with work schedules that require them to frequently change their sleep patterns have higher rates of cardiovascular diseases, diabetes and cancer.
