Here, with the help of two certified yoga instructors, we explain how to do a headstand safely and correctly, the risks of headstands (including who shouldn’t attempt them), and benefits you may get from incorporating this pose into your practice. In terms of when to do a headstand, Laura Kasperzak, E-RYT 200, registered yoga teacher and CrossFit Level 1 Trainer, suggests that if you’re still learning the move, incorporating it halfway through your yoga practice is a good idea....

When the bacteria in the intestinal tract (i.e., your gut microbiota) lack in volume or diversity, or the wrong types of microorganisms start to flourish, it not only can affect your health, but it can also make healthy weight maintenance more difficult. A probiotic supplement that contains science-backed strains of good bacteria can help maintain or restore a healthy microbial balance to your digestive system.* These supplements deliver certain probiotic strains, such as those from genera Lactobacillus and Bifidobacterium, and when taken regularly, they lay down the good bugs you want in your gut, and over time, your health will thank you for it....

As mbg’s health director, I work with Bland and his team on a regular basis, and I’m always eager to hear his insights on an array of health and well-being topics. So when I first heard him rave about a new “super ingredient” he’s working with, I was immediately intrigued. The star food: Himalayan tartary buckwheat. Where HTB is particularly unique, however, is its resilience and ability to grow amid challenging circumstances....

But caffeine is also a stimulant that influences neurotransmitters such as dopamine—which raises the question: Could ingesting caffeine in the form of coffee, tea, or any other source be a safe way to help alleviate ADHD symptoms, or would it just make things worse? And is combining caffeine with ADHD medication even OK, or is it potentially dangerous? Caffeine predominantly does this by acting as an adenosine receptor antagonist. Caffeine is similar in structure to adenosine, a chemical that binds to receptors in the brain and subsequently slows down the activity of neurons that produce attention-boosting neurotransmitters like dopamine....

Since meeting my husband, I had tried three different types of oral contraceptives. Each one had side effects that put a tremendous strain on our relationship.The first pill made me bleed profusely every time we had sex. The second caused me to become jealous and paranoid. We argued loudly, intensely, emotionally, and often in public. My self-esteem was rock bottom, and I lashed out at any perceived offense. The third option was just the final shovel of dirt on my already well-buried libido....

But how long sex “lasts” for women is a complicated question because it’s mixing together a lot of assumptions about what acts are involved in a sexual encounter, how important orgasms are, and how women’s orgasms actually work. That said, there is no average amount of time a woman “lasts” in bed. While people with penises usually can only have one orgasm (coinciding with ejaculation) per sexual session, people with vulvas have a much shorter refractory period (aka recovery time between orgasms) and can thus have multiple orgasms in a single sexual session....

Of the different omega-3s out there, three are probably the most well-known: EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). Each is a little different and has its own unique roles in the body. Here’s what the latest research and top experts have to say about how much omega-3s to aim for, who might need more than others, and your best options for meeting your needs. Here’s the deal: There is an established daily nutritional requirement (aka adequate intake or “AI”) for ALA, the omega-3 you’ll find in plant sources like flaxseed, chia seeds, soy, and walnuts....
