One week of sleep deprivation can alter your genes

Damn it.

Getting fewer than six hours’ sleep per night deactivates genes which play a key role in the body’s constant process of self-repair and replenishment, according to a new study. Our bodies depend on genes to produce a constant supply of proteins which are used to replace or repair damaged tissue, but after a week of sleep deprivation some of these stopped working.

The week of sleep deprivation was found to have altered the function of 711 genes, including some involved in metabolism, inflammation, immunity and stress. Inadequate sleep also interfered with genes which are designed to become more or less active at certain points in the day, by throwing off the body’s 24-hour internal clock.
