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.

M_Id_401088_Kids_SleepGetting 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.

Want to prevent frailty when you grow old? If so, then start maintaining good heart health. A new study indicates that low heart disease risks among older people may help them to prevent frailty.

Frailty is a condition associated with decreased physiological reserve and increased vulnerability to adverse health outcomes. The outcomes include falls, fractures, disability, hospitalisation and institutionalization.

The findings, published in the Journal of Gerontology, found that severe frailty was 85 per cent less likely in those with near ideal cardiovascular risk factors.

The study also found that even small reductions in risk factors helped to reduce frailty as well as dementia, chronic pain and other disabling conditions of old age.

“This study indicates that frailty and other age-related diseases could be prevented and significantly reduced in older adults. Getting our heart risk factors under control could lead to much healthier old ages,” said co-author Joao Delgado from the University of Exeter in Britain.

For the study, the researchers analysed data from more than 421,000 people aged between 60-69. The participants were followed up over 10 years.

The researchers analysed six factors that could impact on heart health. They looked at uncontrolled high blood pressure, cholesterol and glucose levels, plus being overweight, doing little physical activity and being a current smoker.

“Individuals with untreated cardiovascular disease or other common chronic diseases appear to age faster and with more frailty,” the researchers said.

“Now our growing body of scientific evidence on ageing shows what we have previously considered as inevitable might be prevented or delayed through earlier and better recognition and treatment of cardiac disease,” they noted. (IANS)
