Martha Lentz had a long career conducting nursing research, always pursuing new research questions. Over her career she conducted studies on topics like sleep cycles, menstruation symptoms, insomnia types, sleep quality, delta sleep, fibromyalgia, nocturnal asthma in children, and more. Her research was funded by sources like the National Institutes of Health and involved collecting data using methods like polysomnography, actigraphy, and symptom diaries. Overall, her research provided new insights into various health conditions and advanced the scientific understanding of topics related to sleep.

15. What does saying I have goodWhat does saying I have good
sleep or poor sleep mean?sleep or poor sleep mean?
Good sleep is what I am used to experiencing
Poor sleep, if different from past experience
Does PSG poor sleep arise from same
mechanism in self-reported good and poor
sleepers?
Are subtle PSG differences making the mis-
match of self-report and PSG sleep quality?
