Sleepless Nights = Worse Fights
We know that hunger can leave us susceptible to poorly-handled arguments with a partner. So, too, can insufficient sleep. Researchers have found that following nights of poor sleep (less than 7 hours), couples experience more conflict and more difficulty resolving conflict amicably. Sleep deprived partners may have a harder time bringing patience, humor and kindness to those heated moments that every couple faces, as compared to better rested partners.
