Know the facts about CBD products
The extract from the cannabis plant is the hot new treatment for all kinds of ailments, but don't buy into it just yet.
Cannabidiol (CBD), extracted from the cannabis or hemp plant, has been promoted as the latest miracle cure for everything from aches and pains to anxiety and sleep disorders. There is a good chance you've heard a friend share his or her story about the wonders of CBD.
But is it miraculous — or just a mirage?
"CBD is being used over the counter in a range of ways that is not supported by the science," says Dr. Jordan Tishler, instructor of medicine at Harvard Medical School and president of the Association of Cannabis Specialists. "There is still much we don't know. But aggressive marketing, hype, and word of mouth have made CBD like a drug version of the emperor's new clothes. Everyone says it works, but lab studies suggest that it's really not what people think."
Explaining high blood pressure
Ask the doctor
Q. What causes high blood pressure?
A. My answer is going to start in your back yard; stay with me. You're holding a hose, you turn on the water, and it shoots through the hose and out the nozzle. The water is moving because it's under pressure. Similarly, when your heart beats it creates pressure that enables your blood to "water" your body with the nutrients that are in your blood.
Three things affect the amount of pressure that pushes blood through your body: how forcefully the heart pumps, how much blood there is, and how narrow the smallest blood vessels are. That last one may need some explanation. When you're watering plants, and you want the stream of water to go farther, what do you do? You make the nozzle smaller. Narrowing the opening through which the water flows increases the pressure, and the water then is able to reach the distant flowerbed.
Meditation: There's an app for that
This age-old relaxation method can bring health benefits, and there are many tools to help get you started.
These days it seems like there's an app for almost everything you can do for your health, from tracking your diet and exercise to charting your sleep patterns. So, it's no surprise that there's been a surge in apps to help with meditation, an ancient practice designed to help you focus inward to promote relaxation.
In fact, Apple designated "self-care" — a category that includes meditation, mindfulness, and general wellness — as the 2018 "app trend of the year." This mirrors growing interest in meditation as an overall health strategy, a movement likely driven by a growing body of research showing potential health benefits from the practice.
Answers to the top questions about cannabis extract
Sales of cannabidiol-infused products are expected to top $2 billion by 2021. But is CBD right for you?
Cannabidiol (CBD) is touted as a natural wonder that can help treat symptoms of everything from anxiety to arthritis pain. The plant extract comes from two varieties of cannabis — hemp and marijuana — and is available in creams, tinctures, oils, patches, gummy bears, capsules, and more. You can even add CBD to a latte if you walk into a coffee shop in some cities.
But is CBD safe for older adults? There haven't been a lot of large studies of CBD's safety, but more traditional medicines for pain and anxiety are not free of adverse effects, either. "I think CBD is likely safer than many other treatments people use for pain, insomnia, or anxiety," says Dr. Peter Grinspoon, a primary care physician with Harvard-affiliated Massachusetts General Hospital. Other physicians don't think we know enough about the safety profile of CBD to be sure.
The mental side of recovery
Dealing with the emotional effects from a physical setback can be a challenge. These three strategies can help.
The physical repercussions of a major health issue, like surgery, an injury, or a heart attack, are tough enough without having to also confront the stress, anxiety, and depression that often accompanies it. Yet managing your mental health is just as important as your physical health when it comes to making a full recovery.
"There is no question that your state of mind can dictate how quickly you can return from a physical setback," says Dr. Jeff Huffman, director of the cardiac psychiatry research program at Harvard-affiliated Massachusetts General Hospital.
