Catalysts grown in phosphorus-containing media showed improved onset of activity, increased current density and higher selectivity for water formation.
In contrast, another study found higher carbohydrate meals consumed in the evening may help improve sleep onset but are best consumed four hours before bedtime.
The sour bolus was shown to improve the onset of the oral swallow.
14 Future research is warranted to examine potential risk factors of late bedtime such as daytime napping and how to improve sleep onset time among children with disabilities.
In the study of Lee et al., the addition of 30 mg ketamine in a volume of 30 mL ropivacaine 0.5% did not improve the onset and duration of brachial plexus block because of a low dose of ketamine; however, there was a relatively high incidence of adverse effects [ 22].
Using a counter-balanced within-subjects design, the music was not significantly better than the tones or control conditions in improving sleep onset latency, sleep efficiency, wake time after sleep onset, or percent slow wave sleep, as determined by objective physiological criteria.
Studies on adults have reached generally similar results, showing that an increase in physical activity improves sleep onset and increases sleep duration, particularly in people who have trouble sleeping.
Lai and his co-workers previously proposed that the activity of the doped carbon catalysts was found to be dependent on the graphitic nitrogen content, while the pyridinic nitrogen content improved the onset potential for ORR [30].
Bibliotherapy improved sleep onset latency and sleep efficiency more than did waiting.
In the objective studies, eszopiclone significantly improved sleep onset, TST, and WASO in both populations (p < 0.05) compared to placebo.
