“…The remaining parameters related to sleep and circadian rhythms were within the range of normality according to previous research (Ortiz-Tudela et al, 2010, 2014; Hirshkowitz et al, 2015), and well balanced between groups: sleep quality, F (2,33) = 0.139, p = 0.87, B 01 = 4.369, and mean amount of sleep per night, both during the week before, F (2,33) = 0.821, p = 0.449, B 01 = 2.028, and the night before the experiment, F (2,33) = 1.02, p = 0.37, B 01 = 2.673 ( Table 1 ).…”

“…This equipment integrates three different devices: a temperature sensor (Thermochron ® iButton DS1921H, Dallas, Maxim) placed on the non-dominant wrist at the level of radial artery for measuring the distal temperature rhythm every 10 min; an actimeter (HOBO ® Pendant G Acceleration Data Logger) placed on the arm for registering the rhythms of motor activity and body position every 30 s, and a luxometer (HObO Pendant Light-Temperature Data Logger) that assessed the amount of light received by the participants every 30 s along the day. Body temperature has shown to be an excellent marker of the circadian status (Kerkhof and Van Dongen, 1996; Van Someren, 2006; Sarabia et al, 2008) and, together with actimetry (Ortiz-Tudela et al, 2010, 2014) it constitutes a reliable method for ambulatory assessment of circadian rhythms and sleep. The participants were instructed to wear them 24 h per day throughout the week except for shower time.…”

Blue-Enriched White Light Enhances Physiological Arousal But Not Behavioral Performance during Simulated Driving at Early Night

Vigilance usually deteriorates over prolonged driving at non-optimal times of day. Exposure to blue-enriched light has shown to enhance arousal, leading to behavioral benefits in some cognitive tasks. However, the cognitive effects of long-wavelength light have been less studied and its effects on driving performance remained to be addressed. We tested the effects of a blue-enriched white light (BWL) and a long-wavelength orange light (OL) vs. a control condition of dim light on subjective, physiological and behavioral measures at 21:45 h. Neurobehavioral tests included the Karolinska Sleepiness Scale and subjective mood scale, recording of distal-proximal temperature gradient (DPG, as index of physiological arousal), accuracy in simulated driving and reaction time in the auditory psychomotor vigilance task. The results showed that BWL decreased the DPG (reflecting enhanced arousal), while it did not improve reaction time or driving performance. Instead, blue light produced larger driving errors than OL, while performance in OL was stable along time on task. These data suggest that physiological arousal induced by light does not necessarily imply cognitive improvement. Indeed, excessive arousal might deteriorate accuracy in complex tasks requiring precision, such as driving.

“…Participants completed the Horne and Ostberg 22,36 questionnaire to assess morningness-eveningness. This questionnaire establishes five behavioral categories: (1) definitively morning-type (score ¼ 70-86), (2) moderately morning-type (score ¼ 59-69), (3) neither type (score ¼ 42-58), (4) moderately evening type (score ¼ 31-41), and (5) definitively evening type (score ¼ [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. For this study, these categories were reduced from five to three: (1) morningtype (score ¼ 59-70), (2) neither type (score ¼ 42-58), and (3) evening type (score ¼ 41-16).…”

“…In this study, ACM devices were used, because they are wearable, generally well‐tolerated, and able to estimate participants' sleep in the home environment [Anders, Iosif, Schwichtenberg, Tang, & Goodlin‐Jones, ; Jean‐Louis, Kripke, Cole, Assmus, & Langer, ]. Furthermore, it has been reported that values obtained with ACM are closer to PSG sleep estimations than actigraphy records [Ortiz‐Tudela, Martinez‐Nicolas, Albares, et al, ; In addition, ACM is considered as more reliable than sleep diaries and is currently widely accepted [Ancoli‐Israel et al, ; Tsuchiyama, Nagayama, Kudo, Kojima, & Yamada, ]. It can thus provide sleep information that may be otherwise not easily available in individuals with ASD and ID.…”

Sleep problems (SP) are recognized as a common comorbid condition in autism spectrum disorder (ASD) and can influence core autism symptoms and mental and physical health. SPs can be lifelong and have been reported that adults on the autistic spectrum with and without intellectual disability (ID) present SPs (longer sleep latency, frequent night awakenings, and circadian rhythm sleep-wake disorders). A prospective, objective sleep study was conducted in 41 adults with ASD (33 AE 6 years old) and ID and 51 typically developing adults (33 AE 5 years old) using ambulatory circadian monitoring (ACM) recording wrist temperature, motor activity, body position, sleep, and light intensity. The findings indicated that individuals with ASD presented sleep difficulties including low sleep efficiency, prolonged sleep latency and increased number and length of night awakenings, together with daily sedentary behavior, and increased nocturnal activity. Furthermore, indications of an advanced sleepwake phase disorder were found in these autistic adults. Examining sleep and markers of the circadian system showed significant differences between adults with ASD and ID and an age-matched, healthy adult population. The sleep disturbances described for this sample of adults with ASD and ID are similar to those of already described for adults with ASD without ID; their relationship with intellectual ability should be further studied. Improving knowledge of sleep patterns in ASD adults with ID might help to designed targeted interventions to improve their functioning and reduce family stress. Autism Research 2019, 12: 66-79.Lay Summary: SPs are very frequent in autism from childhood to adulthood. We recorded sleep with a watch-like device in adults with autism and ID and compared sleep patterns with nonautistic volunteers. Results showed poorer sleep conditions in adults with autism (increased sleep latency and number/length of night awakenings) that resulted in decreased sleep efficiency. Increasing knowledge of the SPs in adults on the autism spectrum will allow to improve their and their families' quality of life.
