Toronto: Good quality of eight to nine hours sleep every night, clubbed with other healthy lifestyle behaviours, can reduce the negative consequences of stress in kids, suggests new research.
Getting a good night’s sleep might buffer the impact of stress on kids’ cortisol level, which is a hormone produced in the adrenal gland to regulate the body’s metabolic, cardiovascular and immune systems.
While short-term exposure to cortisol prepares the body for the “fight or flight” response, long-term exposure to cortisol can put people at risk for health problems, like heart diseases, weight gain and depression.
“It is important that parents educate their kids at an early age about the importance of consistent and healthy sleep habits,” said lead author of the study Jinshia Ly from Concordia University in Montreal, Canada.
For the study, the research team recruited 220 kids aged eight to 18 years old. The participants gave saliva samples from which their cortisol levels were measured.
The kids and their parents also answered questions about stress, sleep habits and bedtime routines.
The researchers found that poorer sleep quality, regardless of how long kids spent sleeping, promoted the negative effects of stress on their cortisol levels.
Sleeping throughout the night without waking up, feeling rested in the morning, and absence of sleep problems, such as nightmares, apnea and snoring, are examples of a better quality sleep,” Ly noted.
The study was published in the journal Psychoneuroendocrinology.
They call her the “young miracle.” A baby who was admitted to an Ebola treatment center just six days after birth has now recovered from the virus.
Congo’s health ministry calls the baby the youngest survivor in what is now the world’s second-deadliest Ebola outbreak.
The ministry late Thursday tweeted a photo of the infant, swaddled and with her tiny mouth open in yawn or squall, surrounded by caregivers who watched over her 24 hours a day for weeks.
The baby’s mother, who had Ebola, died in childbirth, the ministry said.
The infant was discharged Wednesday from the treatment center in Beni. “She went home in the arms of her father and her aunt,” the ministry said.
Experts have reported high numbers of children with Ebola in this outbreak, which Congo’s health ministry says has 515 cases, 467 of them confirmed, including 255 confirmed deaths.
The tiny survivor is named Benedicte. In video footage shared by UNICEF, she is shown in an isolated treatment area, cradled in the arms of health workers in protective gear or cuddled by Ebola survivors, called “nounous,” who can go without certain gear such as masks. The survivors are crucial with their reassuring presence, the health ministry said.
“This is my first child,” her father, Thomas, said. “I truly don’t want to lose her. She is my hope.” He gazed at his baby daughter through the clear protective plastic.
Children now account for more than one-third of all cases in this outbreak, UNICEF said earlier this week. One in 10 Ebola cases is in a child under 5 years old, it said, and children who contract the hemorrhagic fever are at greater risk of dying than adults.
While Ebola typically infects adults, as they are most likely to be exposed to the lethal virus, children have been known in some instances to catch the disease when they act as caregivers.
Few cases of Ebola in babies have historically been reported, but experts suspect transmission might happen via breast milk or close contact with infected parents. Ebola is typically spread by infected bodily fluids.
The World Health Organization also has noted that health centers have been identified as a source of Ebola transmission in this outbreak, with injections of medications “a notable cause.”
So far, more than 400 children have been left orphaned or unaccompanied in this outbreak as patients can spend weeks in treatment centers, UNICEF said. A kindergarten has opened next to one treatment center in Beni “to assist the youngest children whose parents are isolated” there, it said.
Health experts have said this Ebola outbreak, the 10th in Congo, is like no other as they face the threat of attack from armed groups and resistance from a wary population in a region that had never faced an Ebola outbreak before. Tracking suspected contacts of Ebola victims remains a challenge in areas controlled by rebels.
