Whenever I get sick I head for bed, but apparently I’m doing wrong:

A huge review of the medical literature showed that there is no evidence that bed rest helps you to heal faster from any medical condition. During World War II, American soldiers were drafted and sent to do their basic training at the Great Lakes Naval Training Center. A major epidemic of flu occurred affecting almost all the troops. Half of the soldiers were kept in bed, while the other half stayed in the vigorous exercise of basic training. Both groups required the same amount of time to recover, although those forced to undergo the rigorous demands of basic training complained more.
