“…Regarding the relatively complex executive function of response inhibition, the current study found that accuracy on the GNG task increased significantly with an afternoon nap, regardless of test session. These findings were partly consistent with some studies (Chen et al., 2018; Ru, Chen et al., 2019). For example, Chen et al.…”

“…For example, Chen et al. (2018) found that a midday nap significantly improved accuracy and reaction speed on the GNG task but did not affect the flanker task performance. Although the GNG and flanker tasks are typical tasks assessing inhibition control, they stress action inhibition and attention inhibition, respectively (Diamond, 2013).…”

“…Studies on how an afternoon nap affects alertness and task performance have revealed both positive (Brooks & Lack, 2006; Mantua & Spencer, 2017; Ru, Chen et al., 2019) and few (Chen et al., 2018; Zhang et al., 2009) effects. Several factors may explain these contradictory findings, such as manipulation of a nap (i.e., duration or timing) (Milner & Cote, 2009) and different tasks employed.…”

“…Several factors may explain these contradictory findings, such as manipulation of a nap (i.e., duration or timing) (Milner & Cote, 2009) and different tasks employed. Studies using various cognitive tasks within one study paradigm evidenced no consistent effects of napping on performance across tasks (Chen et al., 2018; Zhang et al., 2009). For example, compared with the no‐nap condition, an afternoon nap benefited performance on sustained attention and response inhibition but not on conflict monitoring (Chen et al., 2018), suggesting that the cognitive domain, which varied in task complexity, might moderate how napping affects task performance.…”

Previous research revealed inconsistent effects of bright light or a short nap at noon on alertness and performance across different tasks. The current study aimed to explore whether the effects of bright light and a short nap at noon on task performance depended on the cognitive domain. Bright light (1,200 lx, 4,000 K at eye level), nap (near darkness) and control (200 lx, 4,000 K at eye level) conditions were performed from 1:00 to 1:40 PM on three non‐consecutive days with a counterbalanced order across participants. After being assigned to one of three conditions, participants underwent two repeated test sessions, each including a psychomotor vigilance task, a go/no‐go task, and a paced visual serial addition task, with an interval of more than 1 h, to assess the persistent effects of napping and bright light. Subjective sleepiness, vitality, self‐control and mood were also measured. Results showed that accuracy on the go/no‐go task and the paced visual serial addition task improved significantly throughout the entire experiment session after napping, whereas reaction speed on the paced visual serial addition task improved time‐dependently in the bright light intervention, with a higher reaction speed in only the first test session. Nearly all subjective states benefited from napping but not from bright light. These findings suggested that the effects of bright light and an afternoon nap on task performance would depend on the cognitive domain. An afternoon nap may elicit more effective and persistent benefits on task performance and subjective states.

“…Daytime nap deprivation is considered sleep loss, particularly for people who are habitual nappers, as daytime naps are frequently included in their total sleep time. in China, most people prefer a brief nap at midday or early afternoon as a practical option to alleviate the post-lunch dip or compensate for insufficient sleep at night ( 17 ). In total, 38.91% of Chinese students nap, with 65% of them napping at least once a week ( 18 , 19 ).…”

Nap deprivation is regarded as a sleep loss for habitual nappers. The beneficial effects of napping and moderate-intensity aerobic exercise on the reduction in planning ability following nighttime sleep deprivation have been proven. However, it is still unknown whether it can improve the performance decline caused by daytime nap deprivation in habitual nappers. Seventy-four healthy adults who had a long-term habit of taking naps were assigned to three interventions after receiving nap deprivation: (1) Control group (no intervention); (2) Nap group (15-min sitting naps); (3) Exercise group (15-min aerobic exercise), in which subjective alertness, mood, fatigue, and task performance in objective alertness (Psychomotor Vigilance Task, PVT) and planning ability (the Tower of London Task) were measured. Results showed that nap deprivation negatively influenced some performance on the psychomotor vigilance (i.e., response times and 10% slowest response time) and planning ability (i.e., planning time). And acute moderate-intensity aerobic exercise improved psychomotor alertness (i.e., response times) and planning ability (i.e., execution accuracy, execution time), a 15-min sitting naps only alleviated subjective fatigue, whereas some performance (i.e., response times) deteriorated when no intervention was used. These findings suggested that acute moderate-intensity aerobic exercise has a better restorative effect on the reduced planning ability and objective alertness due to nap deprivation compared to sitting naps.

Dissociable brainstem functional connectivity changes correlate with objective and subjective vigilance decline after total sleep deprivation in healthy male subjects

The maintenance of vigilance relies on the activation of the cerebral cortex by the arousal system centered on the brainstem. Previous studies have suggested that both objective and subjective vigilance are susceptible to sleep deprivation. This study aims to explore the alterations in brainstem arousal system functional connectivity (FC) and its involvement in these two types of vigilance decline following total sleep deprivation (TSD). Thirty‐seven healthy male subjects underwent two counterbalanced resting‐state fMRI scans, once in rested wakefulness (RW) and once after 36 h of TSD. The pontine tegmental area and caudal midbrain (PTA‐cMidbrain), the core regions of the brainstem arousal system, were chosen as the seeds for FC analysis. The difference in PTA‐cMidbrain FC between RW and TSD conditions was then investigated, as well as its associations with objective vigilance measured by psychomotor vigilance task (PVT) and subjective vigilance measured by Stanford Sleepiness Scale. The sleep‐deprived subjects showed increased PTA‐cMidbrain FC with the thalamus and cerebellum and decreased PTA‐cMidbrain FC with the occipital, parietal, and sensorimotor regions. TSD‐induced increases in PVT reaction time were negatively correlated with altered PTA‐cMidbrain FC in the dorsolateral prefrontal cortex, extrastriate visual cortex, and precuneus. TSD‐induced increases in subjective sleepiness were positively correlated with altered PTA‐cMidbrain FC in default mode regions including the medial prefrontal cortex and precuneus. Our results suggest that different brainstem FC patterns underlie the objective and subjective vigilance declines induced by TSD.
