It's no secret that a lack of sleep can make a person cranky. One study has shown that the threshold for lack of sleep we can get away with is much lower than we thought: one night.

A study by the University of California found that if one member of a couple failed to get a good night's sleep for even one night, they were more likely to fight:
The results showed that even for those who were good sleepers, just a single night's poor sleep was associated with increased relationship conflict the next day and only one partner in the couple had to to have a bad night's sleep for the their relationship to suffer the next day.
The best part is that the inverse of this trend means if you focus on getting plenty of rest, it helps couples get along, which leads to getting more restful sleep. We've always known sleep is important, realising how sensitive we are to instability can help keep couples focused.
