A study found that certain parenting behaviors, such as cosleeping and giving food to children after waking, can lead to sleep disturbances later in childhood. These behaviors were associated with bad dreams, short total sleep time, and delays in falling asleep.
A Université de Montréal study found that parents' bedtime behavior has a direct impact on children's sleep patterns. Giving children food or drink after they wake can cause bad dreams, short sleep time, and delays in falling back asleep. Staying with children at the beginning of sleep appears protective against these issues.
Excessive daytime sleepiness in children is linked to increased symptoms of anxiety and depression later in life. Parents' reports of their child's sleep patterns also show a correlation with emotional and behavioral difficulties.
Infants who slept less than 12 hours per day had a higher risk of being overweight at age 3 than those who slept 12 hours or more. The study also found that restricting sleep changes hormone levels, stimulating hunger and increasing weight gain.
Sleep problems are extremely common in children with ADHD, associated with poorer child psychosocial quality of life and caregiver mental health. The prevalence of mild to moderate sleep problems was found to be significant, with difficulties falling asleep and resisting bedtime being common symptoms.
Research highlights the long-term consequences of childhood sleep disorders on mental health, including emotional and behavioral changes. Experts stress the need for better recognition and treatment of sleep disorders in children to prevent future problems.
Infants and toddlers who sleep less than 12 hours a day are twice as likely to become overweight by age 3. High levels of television viewing combined with less sleep elevates the risk, especially when children watch TV for two or more hours a day.

The study found that short-wavelength blue light induced significant effects on circadian rhythms, melatonin secretion, and alertness in both patients.
A new study published in JAMA found that the sedative drug dexmedetomidine improves intensive care sleep quality and reduces instances of coma and delirium compared to lorazepam. The study showed that dexmedetomidine resulted in 30% fewer patients experiencing coma and an average of four more coma-free days.
A study suggests that honey is more effective than over-the-counter cough medicines in relieving children's coughs and improving sleep during colds. Honey was found to yield the greatest improvement compared to no treatment or dextromethorphan, an over-the-counter medication commonly used for children's coughs.
A study found that buckwheat honey provided better relief of nighttime cough and sleep difficulty in children than no treatment or dextromethorphan, a common cough suppressant. The study showed honey reduced the severity, frequency, and bothersome nature of nighttime cough from upper respiratory infections.
Individuals with current or past insomnia are more likely to report a family history of the sleep disorder than those who have never had it. The study also found that subjects with a family history of insomnia endorsed higher scores on measures of insomnia severity and anxiety symptomatology.
A study of 10 postmenopausal women found that lower estradiol levels and higher luteinizing hormone (LH) levels correlated with poor sleep quality. Higher body temperature before and during sleep also contributed to poorer sleep efficiency and increased LH levels.
