Regular bedtimes better for young minds

If your children are throwing temper tantrums because sleep seems unappealing, consider that it may be OK to let them stay up a little longer, as long as bedtime happens around the same time every night.

A new study suggests that consistency of young children's bedtime is associated with positive performance on a variety of intellectual tests. The study was published in the Journal of Epidemiology and Community Health.

"If the child prefers to go to sleep a little bit later, but it’s done regularly, that’s still OK for them, according to the evidence," said Amanda Sacker, professor in the Department of Epidemiology and Public Health at University College London. FULL POST

Choir singers’ hearts beat as one

Singing together can be an emotional experience.  As churchgoers, choir singers or sports fans raise their voices as one, they feel connected.

Turns out, that connection may have a physiological foundation. A small study suggests people who sing together have synchronized heartbeats.

Singers often inhale and exhale at similar times. When your heartbeat is connected to your breathing pattern, it’s called respiratory sinus arrhythmia, or RSA. RSA can have a soothing effect on the cardiovascular system. For instance, past studies have shown guided breathing – like what’s done in yoga – can be beneficial for high blood pressure problems.

“If this is correct, singing would probably have the same effect,” said Bjorn Vickhoff, a professional singer/songwriter-turned-neuroscientist at the University of Gothenburg in Sweden.
