Physics is good for your health, now and in years to come

Yes, physics is good for your health. And that’s not only because it’s good to know that peeing on high power lines is a bad idea. It’s also because, if they wheel you to the hospital, physics is your best friend. Without physics, there’d be no X-rays and no magnetic resonance imaging. There’d be no ultrasound and no spectroscopy, no optical fiber imaging and no laser surgery. There wouldn’t even be centrifuges.
But physics is good for your health in another way – as the resort of sanity.
Human society may have entered a post-factual era, but the laws of nature don’t give a shit. Planet Earth is a crazy place, full with crazy people, getting crazier by the minute. But the universe still expands, atoms still decay, electric currents still take the path of least resistance. Electrons don’t care if you believe in them and supernovae don’t want your money. And that’s the beauty of knowledge discovery: It’s always waiting for you. Stupid policy decisions can limit our collective benefit from science, but the individual benefit is up to each of us.
In recent years I’ve found it impossible to escape the “mindfulness” movement. Its followers preach that focusing on the present moment will ease your mental tension. I don’t know about you, but most days focusing on the present moment is the last thing I want. I’ve done a lot of breaths and most of them were pretty unremarkable – I’d much rather think about something more interesting.
And physics is there for you: Find peace of mind in Hubble images of young nebulae or galaxy clusters billions of light years away. Gauge the importance of human affairs by contemplating the enormous energies released in black hole mergers. Remember how lucky we are that our planet is warmed but not roasted by the Sun, then watch some videos of recent solar eruptions. Reflect on the long history of our own galaxy, seeded by tiny density fluctuations whose imprint we still see today in the cosmic microwave background.
Or stretch your imagination and try to figure out what happens when you fall into a black hole, catch light like Einstein, or meditate over the big questions: Does time exist? Is the future determined? What, if anything, happened before the big bang? And if there are infinitely many copies of you in the multiverse, does that mean you are immortal?
This isn’t to say the here and now doesn’t matter. But if you need to recharge, physics can be a welcome break from human insanity.
And if everything else fails, there’s always the 2nd law of thermodynamics to remind us: All this will pass away (over time, sooner or later).

Is it possible to ponder physics-related questions mindfully?
What Is Mindfulness?
Source: http://greatergood.berkeley.edu/topic/mindfulness/definition
Mindfulness means maintaining a moment-by-moment awareness of our thoughts, feelings, bodily sensations, and surrounding environment.
Mindfulness also involves acceptance, meaning that we pay attention to our thoughts and feelings without judging them—without believing, for instance, that there’s a “right” or “wrong” way to think or feel in a given moment. When we practice mindfulness, our thoughts tune into what we’re sensing in the present moment rather than rehashing the past or imagining the future.
Though it has its roots in Buddhist meditation, a secular practice of mindfulness has entered the American mainstream in recent years, in part through the work of Jon Kabat-Zinn and his Mindfulness-Based Stress Reduction (MBSR) program, which he launched at the University of Massachusetts Medical School in 1979. Since that time, thousands of studies have documented the physical and mental health benefits of mindfulness in general and MBSR in particular, inspiring countless programs to adapt the MBSR model for schools, prisons, hospitals, veterans centers, and beyond.
Why Practice Mindfulness?
Studies have shown that practicing mindfulness, even for just a few weeks, can bring a variety of physical, psychological, and social benefits. Here are some of these benefits, which extend across many different settings:
• Mindfulness is good for our bodies: A seminal study found that, after just eight weeks of training, practicing mindfulness meditation boosts our immune system’s ability to fight off illness.
• Mindfulness is good for our minds: Several studies have found that mindfulness increases positive emotions while reducing negative emotions and stress. Indeed, at least one study suggests it may be as good as antidepressants in fighting depression and preventing relapse.
• Mindfulness changes our brains: Research has found that it increases density of gray matter in brain regions linked to learning, memory, emotion regulation, and empathy.
• Mindfulness helps us focus: Studies suggest that mindfulness helps us tune out distractions and improves our memory and attention skills.
• Mindfulness fosters compassion and altruism: Research suggests mindfulness training makes us more likely to help someone in need and increases activity in neural networks involved in understanding the suffering of others and regulating emotions. Evidence suggests it might boost self-compassion as well.
• Mindfulness enhances relationships: Research suggests mindfulness training makes couples more satisfied with their relationship, makes each partner feel more optimistic and relaxed, and makes them feel more accepting of and closer to one another.
• Mindfulness is good for parents and parents-to-be: Studies suggest it may reduce pregnancy-related anxiety, stress, and depression in expectant parents. Parents who practice mindfulness report being happier with their parenting skills and their relationship with their kids, and their kids were found to have better social skills.
• Mindfulness helps schools: There’s scientific evidence that teaching mindfulness in the classroom reduces behavior problems and aggression among students, and improves their happiness levels and ability to pay attention. Teachers trained in mindfulness also show lower blood pressure, less negative emotion and symptoms of depression, and greater compassion and empathy.
• Mindfulness helps health care professionals cope with stress, connect with their patients, and improve their general quality of life. It also helps mental health professionals by reducing negative emotions and anxiety, and increasing their positive emotions and feelings of self-compassion.
• Mindfulness helps prisons: Evidence suggests mindfulness reduces anger, hostility, and mood disturbances among prisoners by increasing their awareness of their thoughts and emotions, helping with their rehabilitation and reintegration.
• Mindfulness helps veterans: Studies suggest it can reduce the symptoms of Post Traumatic Stress Disorder (PTSD) in the aftermath of war.
• Mindfulness fights obesity: Practicing “mindful eating” encourages healthier eating habits, helps people lose weight, and helps them savor the food they do eat.
How to Cultivate Mindfulness?
Jon Kabat-Zinn emphasizes that although mindfulness can be cultivated through formal meditation, that’s not the only way. “It’s not really about sitting in the full lotus, like pretending you’re a statue in a British museum,” he says in this Greater Good video. “It’s about living your life as if it really mattered, moment by moment by moment by moment.”
Here are a few key components of practicing mindfulness that Kabat-Zinn and others identify:
• Pay close attention to your breathing, especially when you’re feeling intense emotions.
• Notice—really notice—what you’re sensing in a given moment, the sights, sounds, and smells that ordinarily slip by without reaching your conscious awareness.
• Recognize that your thoughts and emotions are fleeting and do not define you, an insight that can free you from negative thought patterns.
• Tune into your body’s physical sensations, from the water hitting your skin in the shower to the way your body rests in your office chair.
To develop these skills in everyday life, you can try these exercises used in Kabat-Zinn’s MBSR program and elsewhere:
• The raisin exercise, where you slowly use all of your senses, one after another, to observe a raisin in great detail, from the way it feels in your hand to the way its taste bursts on your tongue. This exercise is intended to help you focus on the present moment, and can be tried with different foods.
• Walking meditation, where you focus on the movement of your body as you take step after step, your feet touching and leaving the ground—an everyday activity we usually take for granted. This exercise is often practiced walking back and forth along a path 10 paces long, though it can be practiced along most any path.
• Loving-kindness meditation, which the GGSC’s Christine Carter explains in this post, involves extending feelings of compassion toward people, starting with yourself then branching out to someone close to you, then to an acquaintance, then to someone giving you a hard time, then finally to all beings everywhere.
Over the years on Greater Good, we’ve identified successful programs for cultivating mindfulness; here are some highlights.
• Jon Kabat-Zinn’s Mindfulness Based Stress Reduction Program (MBSR), in which students meet for two-to-three hours per week for eight weeks, practicing at home between classes; it has helped tens of thousands of people build mindfulness.
• Mindfulness-Based Cognitive Therapy (MBCT) adapts the MBSR model specifically for people suffering from depression and chronic unhappiness. Developed by Zindel Segal, Mark Williams, and John Teasdale, MBCT combines mindfulness practices with practices from cognitive therapy, and it has been backed up by a great deal of research.
• Megan Cowan, founder of the Mindful Schools program, offers tips for teaching mindfulness to kids in this Greater Good article.
• In another Greater Good article, Margaret Cullen, founder of the SMART-in-Education program, explains how she uses mindfulness to help teachers take care of themselves and keep from burning out.
• Nancy Bardacke’s Mindfulness-Based Childbirth and Parenting (MBCP) program offers mindfulness training to expectant parents; her book Mindful Birthing describes her program and also offers detailed instructions for cultivating mindfulness in everyday life.
