The effects of nighttime napping on sleep, sleep inertia, and performance during simulated 16 h night work: a pilot study

OBJECTIVES This study aimed to elucidate the effects of two naps taken at night on morning waking state and performance. METHODS The participants were 12 women. The experiment was performed in a laboratory over 2 days (16:00-09:00). In this crossover comparative study, three experimental nap conditions were used (naps from 22:30 to 00:00 and from 02:30 to 03:00 (22:30-NAP), 00:30 to 02:00 and...

Original Contribution Daytime Napping, Nighttime Sleeping, and Parkinson Disease

Preliminary evidence suggests that daytime sleepiness may predate clinical diagnosis of Parkinson disease. The authors examined daytime napping and nighttime sleeping durations, reported in 1996–1997 by 220,934 US NIH-AARP Diet and Health Study participants, in relation to Parkinson disease diagnoses at 3 clinical stages: established (cases diagnosed before 1995, n 1⁄4 267), recent (1995–1999, ...

Napping and Less Disturbed Nighttime Sleep Associated with Reduced Carotid Intima-Media Thickness in Elderly Alzheimer Caregivers

This study tested the hypothesis that disturbed or very short or long sleep durations are associated with subclinical atherosclerosis, as measured by carotid intima-media thickness (CIMT), in a sample of community-dwelling elderly spousal caregivers. Participants were 126 spousal caregivers of a person with Alzheimer’s disease who underwent in-home sleep assessment by wrist actigraphy for 72 co...
