​How Staying Up Late Might Be Tanking Your Mood

If you’ve made a habit of staying up too late and sleeping in every morning, you might be at a greater risk for depression, especially if you have type-2 diabetes, according to a new study presented at the Endocrine Society’s annual meeting in Orlando.

Researchers surveyed nearly 500 people suffering from diabetes in Chicago and Thailand. They included vastly different geographic areas in the study because sleep cycles vary by location. In both groups, night owls—or people who preferred to stay up late—reported experiencing more symptoms of depression than those who fell asleep earlier, regardless of their age, sex, or sleep quality (Having trouble snoozing peacefully?

Could the Club Drug Ketamine Treat Depression?

People have long used club drug Ketamine to get high at parties, but a growing body of research suggests it may also be an effective way to treat depression.

One of the first studies to explore this idea was a 2006 study in which 18 treatment-resistant depressed patients were randomly selected receive either a single intravenous dose of ketamine or a placebo. The study, funded by the National Institutes of Mental Health, found that depression symptoms improved in a single day for 71 percent of the patients given ketamine. Another small study (with 16 patients total) in the 2010 issue of the Archives of General Psychiatry reported that those who had treatment-resistant bipolar disorder experienced relief from depression-related symptoms in as little as 40 minutes after being given ketamine — much faster than most anti-depressants. And in 2016, an animal study published in Nature found that one of the by-products of ketamine, something called a metabolite, remained in the body of mice for days after the drug was taken, which might explain how ketamine works so quickly and why it can provide relief for up to a week.

5 Surprising Reasons You’re Suddenly Broke

You’ve learned from experience that shopping for food on an empty stomach is a bad idea. (Nothing like handing empty bags of chips to the cashier.)

But buying clothes when you’re hungry is even worse for your wallet, finds recent research from the Proceedings of the National Academy of Sciences.

Feeling hungry fires up your brain’s “acquisition” system, the study authors say. Think of it as your “I need something” reflex: Even though the thing you need is food, that reflex makes you more likely to spend money on non-food items, the study shows
