Those who get less sleep are more likely to get a cold

Even though just about everyone knows the importance of a good night’s sleep, many people pride themselves on being able to get by on just a few hours of shut-eye.

But new evidence suggests that skipping sleep does a number on your health. People who sleep six hours a night or less are four times more likely to catch a cold than those who snooze for more than seven hours, according to researchers.

This past winter’s cold season was awful here in San Diego. Some upper respiratory stuff lasted over a month for some friends and family. I got my 7.5 hours per night, was exposed to everyone, and did not get it. Do I credit my regular sleep? You betcha.


I’m fascinated by the research that shows that there is a circadian timing element to the effectiveness of vaccines and other drug delivery (flu shot). I wonder if any public health officials are familiar with this research.
