Less sleep increases risk of getting cold

I’m starting to realize I’m much more efficient when I get a good nights sleep. It’s not that I can’t think and work well when I have to. It’s more along the lines of getting enough sleep allows me to feel good and want to work. The “wanting” to work is key. If it also makes me more healthy and such that’s just a bonus…

They were then quarantined and administered nasal drops containing the common-cold-causing rhinovirus. For five days, the study participants reported any signs and symptoms of illness and had mucus samples collected from their nasal passages for virus cultures.

About 28 days later, they submitted a blood sample that was tested for antibody responses to the virus.

Lower sleep efficiency — percentage of time in bed spent sleeping — was also associated with developing a cold. Participants who spent less than 92 percent of their time in bed asleep were five-and-a-half times more likely to become ill than those whose efficiency was 98 percent or more.
