It's been over two years since the pandemic started, and for many of us, our daily lives have changed in ways we hardly imagined when this decade began. More and more of us are working from home these days, and we're staying at home even when we aren't working. We're more isolated than we used to be, and dealing with a lot more stress and uncertainty. Finding time to take care of our mental health can be a challenge, but it's just as important as ever – and sound has come to play a vital part in that effort, from guided meditation and affirmations to binaural beats and ASMR videos.Two of the most popular and successful forms of sonic therapy are mindful meditation and positive affirmations, and they’ve both come a long way over just the past few years. Mindfulness is the art of being precisely in the moment, without worrying about the past or thinking about the future, or being distracted by anything at all. Completely clearing our thoughts can be tricky, and that’s where guided meditation, which uses sound and music to help lead the way, can help.Studies have shown that the health benefits range from lowering stress and improving our mental well-being to bolstering the immune system and reducing inflammation. Although its roots are thousands of years old, the modern practice of mindful meditation has evolved into high-tech pods and meditation apps you can download for your smartwatch. Some of them can get a little pricey, but if you’re just starting out and want to give it a try, you can find a link to UCLA’s free Mindful app, and a separate list of guided meditation tracks that you can download, on my blog.https://www.uclahealth.org/marc/mindful-meditationsPositive affirmations are another way to help change our mindset, to bolster our self-esteem and sense of optimism. Psychology and even MRI studies have found that they have a positive effect on our behavior and sense of wellness, although they also found that, for people with low self-esteem, affirmations in the future tense work better than the present. So if you find that starting a sentence with “I am” just doesn’t feel right, try saying “I will” instead. I’ve also included a YouTube link on my blog to a morning affirmation video presented by voice artist Prachi Chaube (Prah-chee Chau-bay).https://www.youtube.com/watch?v=WzqFQ9J7YXQBinaural beats are a much more recent discovery when it comes to audio therapy, one that’s still being researched. The idea behind them, though, is fascinating. If you take a pair of headphones and play a sound through them with a slightly different frequency for each ear, your brain blends them together into a new sound that’s the difference between them. So, for example, if the left earphone plays a 300-hertz tone and the right earphone plays a 280-hertz tone, we perceive it as a 20-hertz tone. That’s almost too low for us to hear, but our brains still process it, and different frequencies might resonate with our own neural oscillations to trigger different states of awareness.Listening to that 20-hertz tone, for instance, could cause the brain to enter a beta wave pattern, which can help us feel more awake and alert. A lower binaural beat, such as a 2-hertz tone, might lead to a delta wave pattern, the deepest stage of sleep. Do binaural beats really work? The scientific verdict's still out, but the good news is that studies have shown there's no harm to listening to them, so long as you don't turn the volume up too loud. If you want to try it out for yourself, I've included a video link on my blog. Just make sure you're wearing headphones, or the effect won't work.https://www.youtube.com/watch?v=9TD9SM-5XSkOne of the most recent developments in sound therapy and mental wellness is ASMR: it first emerged as an online phenomenon around 2007 and has become immensely...
