For today’s edition of Dear Mark, I’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re all piecing things together based on limited data—which, I suppose, is the fundamental human experience.
Let’s go:Read More
Anxiety is normal. It’s something we all have experience with—to one degree or another. Most people are anxious about something that hangs over them and follows them around like a personal rain cloud. Then there’s the deeper but still familiar anxiety many of us carry. The anxiety about our self-worth. The anxiety of performance, of social situations. This type can grip us in an uncomfortable, but hopefully not chronic, way. But not all anxiety is run-of-the-mill—or manageable. People with Generalized Anxiety Disorder, for instance, might have trouble leaving the house, ordering a coffee from Starbucks, going to work. Anxious thoughts cycling through their brains often keep them up at night. When untreated, people with this level of anxiety can end up living in a state of perpetual fear. The conventional approach is to take anti-anxiety meds, which can be genuinely life-saving for some people. Nonetheless, these can come with downsides that vary depending on an individual’s dosage and reactions—and the nature of the particular medication itself. Some meds result in few side effects, but others’ effects can be heavy. For instance, there are the benzodiazepines, highly-addictive tranquilizers with the potential for abuse. They make driving unsafe. They lower productivity. They sedate you. When necessary for the severity of the condition, these side effects may be worth it. In other cases, a person might have more space to experiment and want to explore a different route. In some cases, people choose to try natural anxiety aids. These are supplements, nutrients, and herbs that have been designed across millennia by nature (and maybe some input from green-thumbed healers). They might not always be enough for something as serious as a clinical anxiety disorder (please talk to your doctor before making any adjustment or addition to your medication), but at least some may be important complements to a prescribed regimen. For those who want or need an alternative strategy for anxiety beyond meditative practices and general good health, these natural remedies may be worth a try. First, the NUTRIENTS…. These are basic vitamins, minerals, and amino acids that your body needs to work. They are non-negotiable. You don’t have to get them through supplements—in fact, that should be a last resort after food—and I wouldn’t expect “drug-level” effects, but you do need to get them. 1. Long Chained Omega-3 Fatty Acids Some human evolution experts maintain that the human brain wouldn’t be the human brain without steady and early access to coastal food resources—fish and shellfish rich in long chain omega-3s. If the long-chained omega-3s found in fatty fish and other sea creatures made our brains what they are today, it’s safe to assume that our brains work better when we eat them today. And if we’re talking about anxiety, that appears to be the case: Studies in substance abusers find that supplementing with enough fish oil (and, yes, here’s what I use regularly) to raise serum levels of the long chain omega-3 fatty acid EPA reduces anxiety, while increases in DHA (the other long … Continue reading “10 Natural Anxiety Remedies”Read More
The burgeoning CBD oil scene has made finding a product easier than ever, but it’s also made choosing a product harder. If you recall my post from years ago on decision fatigue, you’ll know what I’m talking about: the paralysis of too many choices…. I know my readership, and I know you’re the type of people who will wonder about optimizing their CBD ingestion. This stuff isn’t cheap, and it’s perfectly rational to want to get your money’s worth.
While the compound itself—cannabidiol, or CBD—doesn’t change from product to product, the way it’s administered does.
(Just a reminder that we’re talking here about CBD oil, a.k.a. “hemp extract,” a legal form of cannabis with extremely low levels of psychoactive THC: there’s no “high” with CBD oil, but CBD oil does contain cannabidiol, a component with big physiological impacts for health. Read more on those impacts here. Likewise, “hemp oil” is different from CBD oil; hemp oil isn’t made from the full plant and doesn’t contain substantive CBD content. For the purpose of this article, I’m covering CBD oil only.)
Let’s look at the forms of available CBD oil….Read More
Have you tried hemp oil? After almost a century of being outlawed, hemp—a form of cannabis with extremely low levels of psychoactive THC—is now legal in the United States. This is big news for people interested in the therapeutic effects of cannabidiol (or CBD) because—while hemp doesn’t contain enough THC, the compound that provides the “high” of cannabis, or any other psychoactive compounds—it does contain cannabidiol (CBD). For years, all anyone talked about when they talked about cannabis was the THC content. Breeders focused on driving THC levels as high as possible and ignored the other compounds. Even pharmaceutical companies interested in the medical applications of cannabis focused on the THC, producing synthetic THC-only drugs that performed poorly compared to the real thing. It turns out that all the other components of cannabis matter, too, and foremost among them is CBD. CBD doesn’t get you high, but it does have big physiological impacts. These days, researchers are exploring CBD as a treatment for epilepsy, anxiety, and insomnia. They’ve uncovered potential anti-inflammatory, anxiolytic, and immunomodulatory properties. And now that it’s quasi legal, hundreds of CBD-rich hemp oil products are appearing on the market. What are the purported benefits of using CBD-rich hemp oil, and what does the evidence say? Although CBD research is growing, it’s still understudied and I expect I’ll have to update this post in the near future with more information. But for now, here’s a rundown of what the research says. 1) Hemp Oil For Anxiety Reduction Anxiety can be crippling. I don’t have generalized social anxiety, but I, like anyone else, know what it feels like to be anxious about something. It happens to everyone. Now imagine feeling that all the time, particularly when it matters most—around other people. The average person doesn’t consider the import and impact of anxiety on a person’s well-being. If CBD can reduce anxiety, that might just be its most important feature. Does it? Before a simulated public speaking event, people with generalized social anxiety disorder were either given 600 mg of CBD or a placebo. Those who received CBD reported less anxiety, reduced cognitive impairment, and more comfort while giving the speech. Seeing as how people without social anxiety disorder claim public speaking as their biggest fear, that CBD helped people with social anxiety disorder give a speech is a huge effect. This appears to be legit. A placebo-controlled trial is nothing to sniff at. 2) Hemp Oil For Sleep A 2017 review provides a nice summary of the effects of CBD on sleep: In insomnia patients, 160 mg/day of CBD increased sleep time and reduced the number of arousals (not that kind) during the night. Lower doses are linked to increased arousals and greater wakefulness. High dose CBD improved sleep; adding THC reduced slow wave sleep. In preliminary research with Parkinson’s patients, CBD reduced REM-related behavioral disorder—which is when you basically act out your dreams as they’re happening. More recently, a large case series (big bunch of case studies done at … Continue reading “5 Hemp Oil Benefits For Health and Wellness”Read More
I know we missed Valentine’s Day, but I’ve always said love cannot be contained. Besides: People are always going on dates. People are always searching for new ways to break out of the regular mold, which is completely understandable. Dates are try-outs. You’re spending time with another person to determine how they fit into your life. Unconventional dates that branch out from “dinner, movie, drinks” into more adventurous, creative realms provide excellent feedback for making that determination.
Dates are also a way for established couples to keep things fresh and exciting, to keep the relationship moving. There’s no better way than to try something new.
As it happens, most work for friends, too.
Now, some of these dates are silly or out-of-left field. Some are more serious. And one is a Primal Costanza date—what not to do. But regardless, they are all worth exploring. And—as always—I’d love to hear what you’d add.Read More
In today’s edition of Dear Mark, I’m talking about pregnenolone, the “master hormone.” Most of the hormones we talk about, like testosterone, estrogen, and cortisol, all have pregnenolone as their precursor hormone. What can happen when pregnenolone goes too low? Can taking pregnenolone solve any problems? Is menopause actually a pregnenolone deficiency?
Let’s find out….Read More
A few months ago, I explored the benefits and applications of cold therapy. Today, I’m going to talk about the benefits and applications of heat therapy—one of the most ubiquitous and ancestral therapies in the history of humankind. You name a culture and—as long as they didn’t live in perpetual tropical heat—they probably had some form of heat therapy. Native Americans had the sweat lodge, those of Central America the temazcal. The Romans had the thermae, which they picked up and refined from the Greeks. Other famous traditions include Finnish saunas, Russian banyas, Turkish hammams, Japanese sentó (or the natural spring-fed onsen), and the Korean jjimjilbang. People really like the heat.Read More
It’s about that time: the start of the school year. Bleary-eyed kids everywhere are dragged from bed, thrown into clothing, handed an energy bar and glass of juice, and shuttled off to spend hours sitting at a desk. They come home, do hours of homework, squeeze in some screen time, squeeze some vaguely edible goo into their mouths, update their Facebook status, post a few Instagram pics, and climb into bed by 10 PM sharp, Snapchatting their way to the land of Nod. Then it starts all over again.
I’m exaggerating, a bit. Things aren’t this bad—childhood Facebook usage is actually down! But too many children aren’t getting enough sleep.
It’s been a long time since I published the Definitive Guide to Fish Oils.
Oh sure, here and there I’ve cited some research supporting the beneficial effects of fish fat, but it almost goes without saying that omega-3s are important. Everyone knows it. Even the most curmudgeonly, conventional wisdom-spouting, statin script-writing, lifestyle modification-ignoring doc will tell you to take fish oil. And research in the last few years has not only continually confirmed the health advantages but illuminated new applications—and new physiological explanations—for their essential function in the body.
But what are those benefits, exactly? Why should we be eating fatty fish or, barring access to high quality edible marine life, taking fish oil supplements?Read More
You can “hack” a lot of your health, diet, and lifestyle. You can cook the entire week’s meals ahead of time, buy high-quality prepackaged foods and ready-to-cook meals, cover your nutritional bases with smart supplementation. You can condense your training time by choosing the right exercises and upping the intensity to a sufficient level. You can fast-track your stamina in a fraction of the time with sprints and intervals.
But you can’t hack sleep. There are no shortcuts to sleep. You can’t escape the need for 7-8 hours (perhaps 4-5 if you’re genetically gifted). The human body needs those hours. The human brain needs those hours to pick up trash and clean up around the cranium. And it needs to arrive at them naturally.
Yet, we try to hack it just the same, with terrible results.Read More
