Tossing and turning all night long not only leaves you sleepy the next day, but it can also increase your likelihood of chronic pain.
A sleep study from Johns Hopkins took 32 women.
Half were forced awake in the middle of the night.
Half slept peacefully.
Researchers found those who woke up during the night were more likely to experience spontaneous pain.
Researchers say this problem can affect health care workers on call, or parents caring for infants.
