1. Not feeling rested, no matter how much time you spend in bed. This can be a sign of sleep apnea—obstructed breathing that causes short, repeated awakenings that prevent the transition into deep sleep.


2. Little pains, otherwise known as myalgias, “the malaise you develop when you’re sleep deprived, that sort of achey feeling,” says Colleen Carney, director of the sleep and depression lab at Ryerson University in Toronto. (This is why she thinks delta sleep is essential for her chronic pain patients.)


3. Middle-of-the-night awakenings longer than 20 minutes—this is technically considered insomnia, and often results in over loading on REM sleep at the expense of delta.


4. Forgetfulness—delta sleep is thought to play a role in declarative memory (involving facts or events).


5. Frequent colds, because deep sleep likely helps mediate the immune system. (That’s why you sleep more when you are sick.)
