They say that there's no sense in crying over spilled milk. But what do they know? Crying can get you another glass of milk if you do it loud enough. Plus, crying may serve a real physiologic purpose, according to a study published recently in Emotion, meaning the journal and not in an Emo-kind of way.

For the study, three researchers from the University of Queensland (Leah S. Sharman, Genevieve A. Dingle, and Eric J. Vanman) and one from Tilberg University (Ad J. J. M. Vingerhoets) recruited 197 female undergraduate students. They said that they choose all women rather than including men because pilot testing of sad videos had revealed that more women than men cried or at least more women revealed that they were crying. This did not account for the men who cried inside or used some bro-language or high fives to hide the crying.

The research team then showed each of the study participants either a video that are supposed to make them feel sad (sad videos) or a video that was not supposed to elicit any emotion (neutral videos) like something from a documentary or a ted talk. Each video lasted for close to 18 minutes. After the video, the researchers noted whether or not each participant had cried while watching the video. Ultimately, 65 participants watched the neutral video, 71 watched the sad video and cried during it, and 61 watched the sad video and did not cry. Presumably, no one cried during the neutral video. But then again, actor Bryce Dallas Howard was able to cry when Conan O'Brien talked about Home Depot in this Conan clip:

Then, each participant underwent a Cold Pressor Stress Test (CPT), which involved placing the participant's left hand, up to the wrist, in cold 0° to 5°C water. Unless you are the Iceman or Killer Frost, this is supposed to be painful. The research team measured how long each participant could stay in this position until pulling her hand out of the water. During the study, the research team continuously measured each participant's heart rate and respiratory rate and periodically measured cortisol levels from saliva samples. Cortisol is a stress-hormone that's produced by the body.

Also, at four points during the study, participants answered questions from the Positive and Negative Affect Scale short form (PANAS). These questions asked the degree to which the participant was experiencing ten different emotions and to rank each on a five-point scale that ranged from a one (very slightly or not at all) to a five (extremely).

When it came to cortisol levels and how long the participants could keep their hands submerged in the cold water, the study ended up finding not much difference between the neutral video watchers, the sad video non-criers, and the sad video criers. So if you are about to dunk yourself in cold water or take a cold shower, it may not help to cry first.

But here's a difference that the study found. Are you ready? Take a deep breath. The difference was breathing rates. While watching the videos, the non-criers tended to have elevations in their breathing rates, whereas, by contrast, the criers tended to maintain their initial breathing rates. In other words, tearing up could have helped participants better control their breathing rates. This provides further evidence that crying may help you better regulate arousal, serving as an emotional release.

Another interesting finding was that right before crying, participants tended to experience decreases in their heart rates, seemingly in anticipation of the crying. Once the crying began, their heart rates then tended to creep back up but not above where their heart rates had been before everything began. This may be further evidence that crying has a beneficial regulatory effect on your physiology.

So perhaps next time you start crying you can tell people that you are regulating your physiology. You've probably heard of people saying that they had a good cry and feel better after they've let the tears flow. It can be important to find reasonable ways to periodically release your emotions. Otherwise, you may end up bottling everything up like a hot air balloon that can explode when you least expect it.

Moreover, crying can be a way of communicating. It's really the only way that babies can express their needs before they learn how to say things like "why you throwing shade on me," or "I'm not Gucci." Crying can help communicate to others that you need more sympathy, comfort, or help. Of course, this can be misused. You don't want to cry every time your order at a restaurant doesn't come out right. And of course, there is the whole concept of crocodile tears: people crying to get something when they don't really mean it.

Crying can also be a way of communicating with yourself. Even when you cry alone, you may be telling yourself about your own state because, like many people, you could be terrible at practicing your own emotions and situation. Tears could be your body's way of saying, "hey, take a break," or "something's not right," or "take care of yourself." Tearing up can then be a way of your body literally crying out to you.

Your body is a complex system. Crying can be complex. Your tears can flow when you are very sad, very angry, or even very happy. Better understanding what causes us to cry and what happens as a result could help us better handle their emotions and stress.

Kombucha may help control blood sugar in Type 2 diabetics: study

A SCOBY may look pretty gross, but new research suggests the bacteria and yeast glob could help Type 2 diabetics lower their blood sugar levels.

The study found participants who consumed 8 ounces of kombucha for four weeks saw their blood sugar levels decrease from 164 to 116 milligrams per deciliter.

Scientists from Georgetown University, the University of Nebraska-Lincoln and the nonprofit MedStar Health reported the findings Tuesday in the Frontiers in Nutrition journal.

Kombucha, a fermented, sweetened black tea drink produced from a symbiotic culture of bacteria and yeast, has long been touted as healthy, based on claims it enhances immunity and energy levels, reduces food cravings and alleviates gut inflammation.

“Some laboratory and rodent studies of kombucha have shown promise, and one small study in people without diabetes showed kombucha lowered blood sugar,” study co-author Dr. Dan Merenstein, a professor at Georgetown’s School of Health, said in a statement.

“But to their knowledge, this is the first clinical trial examining effects of kombucha in people with diabetes,” he continued. “A lot more research needs to be done, but this is very promising.”

In the study, one group drank the kombucha while another downed a placebo beverage.

No one was told which drink they were receiving.

After a two-month period to “wash out” the biological effects of the beverages, the mixtures were swapped between the groups, who were directed to drink their new concoction for four weeks.

The placebo beverage didn’t seem to have any effect on blood sugar levels.

The American Diabetes Association advises that fasting blood sugar levels should be between 80 to 130 milligrams per deciliter.

Participants drank kombucha produced by Craft Kombucha, a commercial manufacturer in the D.C. area.

The study authors noted different brands of kombucha have slightly varying microbial mixtures.

“However, the major bacteria and yeasts are highly reproducible and likely to be functionally similar between brands and batches, which was reassuring for their trial,” said Dr. Robert Hutkins, the study’s senior author.

According to the Centers for Disease Control and Prevention, more than 37 million Americans have diabetes, and 90% to 95% of them have Type 2 diabetes.

Approximately 96 million American adults — more than 1 in 3 — have prediabetes.

“Diabetes itself is the eighth leading cause of death in the US as well as being a major risk factor for heart disease, stroke and kidney failure,” lead study author Dr. Chagai Mendelson said.

Mendelson said further studies are needed to assess kombucha’s effect on diabetes.

“We hope that a much larger trial, using the lessons they learned in this trial, could be undertaken to supply a more definitive answer to the effectiveness of kombucha in reducing blood glucose levels, and hence prevent or help treat Type 2 diabetes,” he added.

Study: Vitamin D Supplements May Help Reduce Risk of Heart Attack in Older People

Fact checked by Sarah Scott

Taking vitamin D supplements may help reduce the risk of major cardiovascular events (like heart attacks) for older adults, according to a new study.

The trial, which was based out of Australia, assessed 21,315 people who ranged from 60 to 84 years old. They randomly gave one group of 10,662 participants one capsule of 60,000 IU vitamin D, while a placebo was given to 10,653 participants.

The supplements and the placebo were taken orally by participants at the beginning of each month for up to 5 years, with the clinical trial starting in 2014 and concluding in 2020.

Researchers excluded people from the trial with a history of hypercalcemia, or high calcium levels, overactive thyroid, or hyperparathyroidism, kidney stones, osteomalacia, or "soft bones," sarcoidosis, which is an inflammatory disease, or who were already taking more than 500 IU per day of vitamin D supplements.

Study author Rachel Neale, PhD, told Health that there have been plenty of observational studies suggesting that the concentration of 25 hodroxy vitamin D [25(OH)D—the molecule that is measured to determine vitamin D status—in the bloodstream is "inversely associated with health outcomes."

The opposite has been examined less.

While the largest clinical trial of its kind, the researchers acknowledge that the study was relatively small, and more work needs to be done to understand the effectiveness of these kinds of supplements, especially in people who are taking statins or other medications to manage cardiovascular disease.

Neale, who also serves as the deputy coordinator of the Population Health Department at QIMR Berghofer Medical Research Institute, noted that the association between vitamin D and cardiovascular health risk may not be causal.

"Randomized controlled trials are needed to determine whether supplementing people with vitamin D would Strengthen health outcomes," she said.

Over the course of the trial, 1,336 of the participants experienced a major cardiovascular event—this was evenly divided between the placebo and vitamin D supplement groups.

The research team found that 6.6% of those in the placebo group and 6% in the supplement group experienced a cardiovascular event during those five years.

Those in the vitamin D supplement group seemed better protected from these heart disease events; this group experienced a rate of major cardiovascular events that was 9% lower compared to what was seen in the placebo group.

This comes out to about 5.8 fewer cardiovascular events per 1,000 participants. The heart attack and coronary rates were 19% and 11% lower, respectively, in the vitamin D group. That being said, the rate of stroke showed no difference between the placebo and supplement groups.

When asked what is known about vitamin D and its impact on heart health, Boback Ziaeian, MD, PhD, an assistant professor of medicine at the David Geffen School of Medicine at UCLA in the Division of Cardiology, told Health that there are many studies out there on vitamin D "that span basic sciences, observational research, and clinical trials."

That being said, it's only very recently that we've started seeing large randomized trials like this one that focus on vitamin D supplements as a mechanism to prevent cardiovascular disease, cancer, and even dementia.

"These trials have all largely been negative for their primary endpoint design. The latest Australian study is the first large study to suggest a possible benefit and that is very uncertain," said Ziaeian, who is unaffiliated with this clinical trial.

Essentially, more needs to be examined here.

Neale said that there are a number of different potential mechanisms inherent in vitamin D that could be beneficial for your heart.

She mentioned that vitamin D "can influence the renin-angiotensin-aldosterone system, which influences blood volume and vascular resistance." She also noted that vitamin D can also lower inflammation and "reduce cardiac remodeling."

"People have hyped Vitamin D for a long time, but blood levels are heavily confounded by other lifestyle factors like how much time someone spends outdoors or not having other chronic diseases," Ziaeian said.

"So, overall, there's no good evidence that supplementing people with vitamin D does anything beneficial for their health unless they cannot produce it, such as patients with severe kidney disease."

Ziaeian said that he doesn't believe they will see a future where vitamin D supplementation will be part of a prescription from your doctor.

"Looking at the literature overall, I think it is very unlikely that they would find many benefits for any vitamin supplementation that for vitamins we normally ingest with normal food intake or that their body produces," he said.

Neale said that "uncertainty in the evidence may not ever be completely resolved." She said this leaves medical providers in a "somewhat difficult position" when it comes to prescribing vitamin D supplements, outside of treating vitamin D deficiency.

"I would emphasize that even if their findings do indicate a real effect of vitamin D, it is not a magic bullet," she said. "Diet and exercise will play a much more important role."
