The Scientific Reason You Need To Hug Someone Today
Start writing a post

Sure, hugs make us feel all warm and fuzzy inside, but it turns out they can also reduce stress, lower blood pressure and decrease our risk of getting sick. Not only does a tight squeeze make us feel good, but it can also have significant health benefits!

With cold and flu season upon us, most people have started to prepare: getting flu shots and consuming enough vitamin C can work wonders, but what about getting in our daily dose of hugs? In a 2014 study by Carnegie Mellon University, people who were hugged more frequently in the days leading up to the study were significantly less likely to catch a cold after having been exposed to the virus.

Why does this happen, though? Well turns out it's mostly due to our little friend, oxytocin. Oxytocin does amazing things for our bodies. It is the same chemical released during childbirth and breastfeeding that bonds mothers with their children. Pressure receptors in our skin respond to the sensation of a hug and activate the vagus nerve. This leads to a release of oxytocin in our bodies and in turn has an array of health benefits. However, this same pathway doesn't occur with flimsy hugs. (You know, the ones you give to your parent's friends you just met or your distant relatives you haven't seen in 10 years.) Those flimsy air hugs won't provide you with nearly the same number of health benefits as a big bear hug will!

If you're hurt, you're in luck! In addition to increased immune functioning, high oxytocin levels also lead to faster healing of wounds and less pain. Hugging releases endorphins, which block the pain pathways to the brain, working as a natural pain killer.

Feeling stressed? Stress can lead to high blood pressure and increased heart rates. Luckily, there's a pretty quick fix as oxytocin also helps lead to lower blood pressure and heart rates! According to a study at the University of North Carolina, women who received more hugs during the study had higher oxytocin levels, lower blood pressure, and lower heart rates. Oxytocin also leads to a reduction in cortisol levels (the stress hormone) in the body.

Not only does oxytocin make us healthier, but it makes us feel pretty dang good, too. Oxytocin triggers the release of dopamine and serotonin (pleasure hormones) in the body, making us feel happy and reducing anxiety and depression. A 2010 study found that animals treated with an oxytocin inhibitor produced more signs of depressive behavior than those who were not.

It's also never too early to start hugging. According to Huffington Post, there may be a link between how frequently babies are hugged and how they manage stress as adults.

While it may seem like hugs are a cure-all treatment, there is a stipulation and it may come as a blow to the "Free Hugs" campaign. According to neurophysiologist Jürgen Sandkühler, what is most important to consider when giving and receiving hugs is whether or not you trust the other person. If the hug comes from a stranger, or is unwanted by either party, oxytocin is not released. In fact, another hormone, cortisol, is released instead, causing an increase in stress due to our perceived violation of distance-keeping behaviors.

All in all, as long as the hug is tight and comes from someone we care about, oxytocin will keep doing it's job. In addition to oxytocin creating mini-miracles in our bodies, psychologically, hugging is extremely beneficial. It makes us feel safe, loved and comfortable while reducing our anxiety and giving us confidence. Hugging is a way of showing our social support for our loved ones, which has benefits of it's own as well. In short, hugs are really freakin' cool, so make sure to take care of yourself this season and get on hugging!

Today is Bisexuality Day and I'm more than ready to give all the bisexuals some love by breaking the stigma. I see you, I hear you, I appreciate you.

Bisexuliaty is a sexual orientation where people can form attraction and/or relationships to more than one gender. More than half of the LGBTQ+ community identifies as bisexual but it comes with a ton of bias, discrimination, and violence. And, honestly, bisexuals tend to be forgotten becuase bi-erasure wants to hold onto biphobia to question the existence and legitimacy of bisexuality.

There isn't one person the coronavirus (COVID-19) pandemic hasn't affected. While COVID-19 is risking everyone's physical health, it's also destroying the world's economy and personal finances, weakening mental health, wreaking havoc on education... and, well, the list goes on.

Among the many things being impacted is love.

A Couple's Wedding In Peru Was Postponed By COVID-19, But A Lifetime Of Love Is Worth The Wait

"We'd prefer to wait and have the wedding that both of us have always thought of."

During their first semester at Instituto de Empresa (IE Business School) while working on graduate degrees in Madrid, Spain, soon-to-be-newlyweds Rory and Gigi met when they were placed in a workgroup together — and the rest was history. Now, four years after their relationship began, the couple's fall plans to get married in Perú, where Gigi is originally from, have since been postponed by COVID-19.

Though things haven't always been easy for the pair because of immigration, starting a skincare business together, and now, canceling their dream wedding because of the pandemic, they have always worked together as a team (maybe we should all be in a workgroup with our future spouses).

A Bumble Couple's Wedding Was Canceled By COVID-19, But Nothing Could Come Between This Perfect Match

"The whole purpose of all the stress and time and tears was that we love each other and that was all that mattered."

Shortly after Kaihla's sister made her a dating profile on Bumble (despite her fear of being catfished), she matched with Shanna, and their chemistry was quickly undeniable. So much so that only a month and a half into dating, Shanna told her best friend "I think I'm going to marry her," and eventually, the nonprofit worker and elementary PE teacher duo proved this to be true.

In the fourth episode of a new docuseries called "Pandemic Weddings" by SoulPancake, the couple opens up about how they met, the difficulties of canceling a non-refundable wedding of their dreams (that took a year and a half to plan), as well as the pain of having family members who didn't support their marriage use the pandemic as a convenient excuse not to come.

This fall was my boyfriend and I's two-year anniversary! In the past for special occasions, we've typically gone out for a movie and dinner or just did something fun in general. However, in the year of COVID, we didn't really feel safe doing something like that.

Instead, we wanted to try something new that kept us significantly more socially distanced. Luckily, I found a TikTok trend a few months ago that gave me the perfect idea! The Target TikTok trend blew up all over for couples and friends alike. It seemed like a fun activity for us but also a good way to get each other gifts that we might not have thought about.

If there's one thing everyone's talking about right now, it's voting — in real life, on social media, and yes, even on dating apps.

And rightfully so! Because is there really anything sexier than someone who cares about using their voice to be the change they want to see? In my opinion, no... not much, honestly.
