Look Up From Your Screen
One of the best things about being in the emergency services is the freedom we enjoy from a traditional office setting. Increasingly, though, our mobile devices are infiltrating our space and chewing up our time and attention. We can be sitting in the cab of an emergency vehicle anywhere, but still be tethered by our phone and tablets, unless we make a conscious choice not to be ruled by techno-diversions.
As a member of the healthcare world, why not set an example to others and choose to heed the advice of experts to look up from the screens to which we all seem addicted? Here are three good reasons:

Melatonin: the body's natural sleep-promoting hormone
Prescriptions for short periods are considered safe, but there is little research into the long-term effectsIn daylight hours there is so little melatonin in the bloodstream that it is barely detectable. But when the sun goes down, the eyes sense the failing light, and part of the hippocampus signals the pineal gland, a pea-sized lump of tissue near the centre of the brain, to ramp up production of the sleep-promoting hormone. Levels of melatonin rise sharply from 9pm, inducing feelings of sleepiness, and remain high until the following morning.Much of the research on prescribing melatonin for children with sleep problems ...

Is My Teenager Depressed or Just Moody? 8 Questions to Consider Before Getting Help
Teenagers are supposed to be moody, right? One moment they are happy and laughing about a silly Youtube video and the next they are slamming their door to their room and crying into their pillow. You tell yourself “Its just hormones,” and try to brush it off. Chances are you are right. Most teenagers do fluctuate in mood to some extent and that is normal. I have a friend who even nicknamed her teen the “Threen-ager” because her daughter resorted to teen meltdowns when she didn’t get her way.
But how do you know if your teen is just moody or if he or she is depressed or even anxious? Knowing the difference coul...

The Scientific Secrets to Preventing Jet Lag
Traveling abroad can be exhilarating. But sometimes it’s easy to discount the crippling jet leg that can set in after traversing multiple time zones—leaving you exhausted, disoriented and possibly causing you to miss out on your vacation.
Jet lag is “something that can ruin a vacation or plague athletes and musicians or have a businessman or woman not perform at their peak,” explains Charmane Eastman, a professor in the Department of Behavioral Sciences and the founding director of the Biological Rhythms Research Laboratory at Rush University Medical Center in Chicago.

Type 2 diabetes-associated variants of the MT2 melatonin receptor affect distinct modes of signaling
Melatonin is produced during the night and regulates sleep and circadian rhythms. Loss-of-function variants in MTNR1B, which encodes the melatonin receptor MT2, a G protein–coupled receptor (GPCR), are associated with an increased risk of type 2 diabetes (T2D). To identify specific T2D-associated signaling pathway(s), we profiled the signaling output of 40 MT2 variants by monitoring spontaneous (ligand-independent) and melatonin-induced activation of multiple signaling effectors. Genetic association analysis showed that defects in the melatonin-induced activation of Gαi1 and Gαz proteins and in spontaneou...
