The findings could enable a simpler way to test for sleeping sickness, improving survival rates and reducing devastating side effects.
A new study by researchers at Hasbro Children's Hospital found that children with sleep-disordered breathing (SDB) who are overweight, have short sleep periods, or another sleep disorder like insomnia are more likely to have behavioral problems. The study revealed that SDB severity had a relatively weaker influence on behavioral outcomes.
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.
