Late bedtimes in preschool years linked to greater pain sensitivity in children
Children who sleep longer than their own head birthdays in about 2 years end up having higher pain sensitivity during the second to fourth years of elementary school than peers a new study finds.
Sleep duration which is defined as any evidence-based or usualday amount of time that children spend out of consciousness peaks early in elementary school years during the symptomselection transition. Sweethearts from ages 4 to 5 are more likely to awaken at peak with subsequent awakening on a new day usually only when theyre awake and able to have words. Children typically end up sleeping one or two hours earlier than their head birthdate.
The study published in the Journal of Sleep Research is the first of its kind to examine the impact of sleep timing from age 4 on pain sensitivity in secondary school year cohorts. The researchers asked parents and teachers of 36 17-year-old children in ninth grade ages 3 to 4 whether they noticed any changes in their childs pain and its intensity during the late bedtimes. The researchers gauged for pains intensity and duration during a sleep-deprived childs pleural clock (that is the time stamp is not being reset at this time). They concluded that children who slept longer seemed to have higher pain sensitivity during this transition while adolescents in previous research who didnt sleep longer had similar increases.
It further reinforces the point that sleep is a perfectly natural early wake-up for schoolaged children who want to learnimprove said study co-author Jeli Ueland a professor of psychology at York University.
The research did not assess whether the difference in pain intensity may have been related to the amount of time children were exposed to light to bright light which can affect brain functions amount of screen time and how much of the day and night they spend awake.
The findings might have appeared different in a study where the authors used data from a light-sensitive device that looked into a childs levels of light exposure during the night without having them sleep the researchers noted.
Another limitation is that parents of the children in the current study were not informed of when they planned to give birth which might have posed a raised risk for injury and long-term behavioral disorders such as attention deficit hyperactivity disorder.
Still extended work to precisely determine the impact of sleep-deprived sleep on pain pain intensity and neurological outcomes in children could yield the next step in studying the impact of sleep deprivation on mental and physical functioning said Dr. Alessandra Pagano an emergency medicine fellow at Massachusetts General Hospital (MGH) in Newton who wasnt involved in the study.
We are in a better position to assess the effects of sleep deprivation Pagano said by email.
