Sleep is for the weak, right? Wrong, according to science.
A new study has found that missing just one night of sleep can really screw with your body. Time to ditch the caffeine for a kip?
Swedish researchers discovered that one sleepless night can change actual genes which control what your body's cellular biological clocks, reports MailOnline. Changes to these 'clocks' can affect everything from appetite to body temperature.
Scientists took fifteen 'normal-weight' men and let them snooze one night and made them stay awake on another.
The men were kept under strict lab conditions with light levels, food intake and movement all being monitored. Even when the men were kept awake, they still had to stay in bed. Cruel.
After testing tissue samples from the men, researchers were surprised at how quickly lack of sleep could impact on genes.
"It was interesting that the methylation of these genes could be altered so quickly, and that it could occur for these metabolically important clock genes," said Dr. Jonathan Cedernaes.
Scientists were left unsure whether the changes could be easily reset by a few good nights sleep, or whether they were more permanent.
Dr. Cedernaes said: "At least some types of sleep loss or extended wakefulness, as in shift work, could lead to changes in the genome of your tissues that can affect your metabolism for longer periods." Eek.
We may not be scientists, but we reckon y'all deserve a good snooze.
