Never go to bed angry - study finds evidence for age-old advice

During sleep the brain reorganises the way negative memories are stored, making them harder to reverse, evidence indicates

Never go to bed angry, the old saying goes, or bad feeling will harden into resentment. Now scientists have found evidence to support the idea that negative emotional memories are harder to reverse after a night's sleep.

The study, published in the journal Nature Communications, suggests that during sleep, the brain reorganises the way negative memories are stored, making these associations harder to suppress in the future.
