Night sleepiness in two groups of student volunteers who stayed awake for one night was assessed at standardized time (22:00, 01:00, 04:00, 07:00) by the Stanford Sleepiness Scale (SSS). One group (N=21) chewed the chewing gum from midnight until the end of the experiment in the morning, while the other group (N=43) was not chewing at all. The results show that both groups at the initial assess...

AIM To determine whether levels of daytime physical activity are associated with sleep duration and night waking in children assessed using accelerometry, and if these associations change over time. METHODS 24-hour accelerometry data were obtained from 234 children at 3, 5 and 7 years of age for at least 5 days at each time. Sleep duration was estimated using the Sadeh algorithm. Time spent i...

This study examined the impact of eating during simulated night shift on performance and subjective complaints. Subjects were randomized to eating at night (n=5; 23.2 ± 5.5 y) or not eating at night (n=5; 26.2 ± 6.4 y). All participants were given one sleep opportunity of 8 h (22:00 h-06:00 h) before transitioning to the night shift protocol. During the four days of simulated night shift partic...

We started the vaccination rollout with intense activity, preparing to use a whole pack of Pfizer-BioNtech vaccine (1170 doses) within 3.5 days delivery, short notice about when it would arrive. Late on December evening our GPs worked through lists older patients, ringing offer appointments precious sixth dose in each vial that had just been sanctioned. Anxiety kept some us awake night before ...
