Mental Health Experts Are Quietly Quitting These 5 Habits This Year

Typical New Year's resolutions tend to fall into two categories: quitting something that no longer benefits you or picking up a new habit in the hopes that it will. Popular nutrition and exercise goals are certainly the most common, but there's more to personal growth than physical health.

As neurologist Dale Bredesen, M.D., author of the New York Times bestselling book The End of Alzheimer's, says, "It's surprisingly common to see people come in with cognitive decline and their vitamin D level is 19 or 20 [ng/mL]." 

For reference, a blood level of 30 ng/mL1 is often considered the minimum cutoff for "normal" vitamin D status, but many experts believe a level of at least 50 ng/mL is crucial to keep your body healthy and feel your best.

But why is vitamin D so important? The sunshine vitamin influences not only brain development2 but also everyday brain function3; it even works to protect your brain as you age3. In fact, one meta-analysis4 conducted in 2019 that reviewed 11 studies on a total of 21,784 participants found significant associations between vitamin D deficiency and both dementia and Alzheimer's disease.

Both Bredesen and functional medicine psychiatrist Kat Toups, M.D., agree: The oral microbiome is too often ignored, yet it's essential to healthy brain function. This is because your mouth is the gateway to your body and the beginning of your gastrointestinal tract (and we likely don't have to remind you of the gut-brain connection). 

"[Your mouth] is right next to the brain," Toups says. "And what's in the mouth and nose can travel right up into the brain so easily… It's quite easy for bacteria to track up there."

That's why "I recommend everyone check out your oral microbiome," advises Bredesen. (He suggests using a service like MyPerioPath.) "Do you have P. gingivalis, T. denticola, prevotella intermedia, F. nucleatum? These organisms are being found in the brain; they're being found in the plaques of coronary arteries… These things are impacting us systemically5," he says. 

PSA: Positivity isn't always beneficial. Developmental psychologist Sasha Heinz, Ph.D., who is an expert in behavioral change and positive psychology, says that some self-help books and overly positive slogans can actually backfire. 

"People [think] this self-development work is cheesy or it's about good vibes only," Heinz says during her interview. "That is so untrue." In fact, a positive-only mindset actually won't get you anywhere. That's not to say optimism isn't important—but pessimism does have its benefits as well, as being realistic about what you can and cannot achieve can lead to greater success. 

Here's some good news: Being a people pleaser isn't a permanent trait. What's more, it can manifest from a young age (read: It's not your fault you have trouble saying no). 

As physician and renowned speaker Gabor Maté, M.D., bestselling author of The Myth of Normal, explains, people receive messages in early childhood that in order to be acceptable, they have to be compliant. "They have to suppress their own will, their own needs, their own perspective, and they have to serve others," he says on the show. As a result, they feel uncomfortable saying no as they grow older.

"Nature's agenda is that we should all develop into independent human beings with our own sense of what we want and what we don't want, our own sense of values, our own sense of perspective on the world, our own desires," he shares. "In other words: Nature wants to set a boundary between ourselves and other people's will." 

It's common to express all of your emotions to someone (anyone!) who will listen. But as award-winning psychologist Ethan Kross, Ph.D., explains on the podcast, that's not always the best idea.

"A lot of people intuit that you should just vent your emotions. Don't keep it bottled up inside," he says. And that's true, to some degree: The notion of venting to alleviate stress isn't entirely unfounded.

Plus, it can be beneficial for your relationships."Venting your emotions to someone else can be really good for strengthening the friendship and relational bonds between two people. It feels good to know that there's someone else out there who cares enough about you that they're willing to take the time to listen," he says.

However, when the venting stops, you might be left with no plan to workshop the problem at hand. To prevent this, "You want to do two things," he says. "[First], you want to find someone who does allow you to share a little bit about what you're going through. It is important for you to feel validated, but at a certain point in the conversation, you ideally want the person you're talking to to help broaden your perspective." Essentially, be selective about who you vent to, and make sure you aren't just wallowing together with no plan of action.
