Rutgers researchers found premature infants between 24-27 weeks have a three times higher risk of dying before first birthday due to SIDS and other sleep-related infant deaths. Safe sleep practices, such as putting infants on their back to sleep, can help compensate for this risk.
A new study by UBC sleep expert Wendy Hall found a correlation between thoughts about infant sleep and parental depression. After a sleep intervention, parental depression lifted significantly, with a notable reduction in mothers' (30%) and fathers' (20%) high depression scores.
Research suggests that night shift work impairs the body's ability to repair DNA damage caused by normal cellular processes. Suppression of melatonin, a hormone regulating the internal clock, is thought to be a key factor in this impairment. This may result in higher levels of DNA damage and potentially carcinogenic effects.

The study also identified a 53% increase in fracture risk for medium-term users and a 20% increased risk for long-term users.
Researchers at Brown University have identified genes with epigenetic tags associated with shorter sleep in young adults. The study used a combination of human and worm experiments to discover the connection, finding that knocking out analogous genes in worms affected sleep patterns.
Researchers designed a new technology that uses machine learning to model personal sleep patterns based on recorded sounds made during sleep. This method allows doctors to diagnose patients under normal sleeping conditions, leading to better treatment outcomes.
Researchers found that poor sleep in people with depression and anxiety can make it harder for the brain to modify negative emotional responses. The study used functional MRI to measure brain activity in a specific region, the dorsal anterior cingulate cortex, which was found to work harder in individuals with lower sleep efficiency.
A study of 35 popular phone-based sleep apps found that most help users set sleep-related goals and track their sleep patterns, but few provide general information about sleep or its benefits. The analysis suggests that there is room for improvement in the development of these apps to educate users about the importance of sleep.

The mutation affects up to 1 in 75 people and can be present in families, with relatives sharing similar signs of persistent sleep problems.
A recent study has identified a gene mutation as the cause of delayed sleep phase disorder (DSPD), a common sleep disorder affecting up to 10% of the public. The CRY1 protein plays a crucial role in regulating the circadian clock, and a single-point mutation can lead to prolonged sleep onset times and irregular sleep patterns.
