New problem linked to ‘jet lag’

Disrupting the internal clock of mice can confuse the animals’ immune systems

Many processes in the body naturally turn on or off with a near-clocklike precision. Sleeping and changes in body temperature, mood and metabolism — the process of turning food into energy — all follow a cycle. This cycle repeats on a near-daily, or circadian, schedule. It’s driven by a master internal “clock,” a clump of brain cells that serve as a timekeeper. Now scientists have found that a confused clock may impair a person’s immune system, a collection of cells that fight infection and d...
