New research from a study conducted at Northwestern University in Chicago has found that a sense of purpose in life could help people sleep better. The study looked at over 800 people ages 60 to 100. Question about sleep quality and motivations in life were the core focus of the study and the researchers discovered that those who felt their lives had more meaning were actually less likely to have sleep apnea and restless leg syndrome along with a higher quality of sleep overall. The new study was published in the journal of Sleep Science and Practice.
