For neuroscientist Sara Lazar, a form of meditation called open awareness is as fundamental to her day as breathing.

“I just become aware that I am aware, with no particular thing that I focus on,” explains Lazar, an associate researcher in the psychiatry department at Massachusetts General Hospital and assistant professor of psychology at Harvard Medical School. “This sort of practice helps me become more aware of the subtle thoughts and emotions that briefly flit by, that we usually ignore but are quite useful to tune into.”

But meditation doesn’t just change your perspective in the moment. Some studies show certain types of meditation offer an array of benefits, from easing chronic pain and stress and lowering high blood pressure to help relieve anxiety and depression. And, as Lazar’s research has shown, meditation can actually change the structure and connectivity of brain areas that help us cope with fear and anxiety.

“It’s become really clear that all of our experiences shape our brain in one way or another,” Lazar says. “A lot of people talk about meditation being a mental exercise. Just as you build your physical muscles, you can build your calm muscles. Meditation is a very effective way of training those muscles.”

What counts as meditation?

More than you might have believed. An intriguing if somewhat perplexing aspect of meditation is that it encompasses a broad range of practices. “It’s clear what is not meditation, but there’s less consensus on what it is,” Lazar says.

Open awareness, Lazar’s go-to meditation, joins other forms, including focused awareness, slow deep breathing, guided meditation, and mantra meditation, along with many variations. At their core, Lazar says, is an awareness of the moment, noticing what you’re experiencing and nonjudgmentally disengaging from intrusive thoughts that might interfere with your ability to attend to this task.

Meditation can also involve sitting with eyes closed and paying attention to your body and any sensations that are present. A regular meditation practice typically involves slowing down, breathing, and observing inner experience.

“Meditation can involve flickering candles, breath awareness, or mantras — all of these things,” Lazar says. “But there’s definitely an element of focusing and regulating your attention.”

A close look at how meditation alters the brain

Small MRI imaging studies have zeroed in meditation’s effects on the amygdala, an almond-shaped structure deep within the brain that processes fear and anxiety as well as other emotions.

Lazar and her colleagues have spent many years laying the groundwork to show how practicing mindfulness-based stress reduction (MBSR) alters the amygdala after only about two months. The MBSR practice in this research consisted of weekly group meetings and daily home mindfulness practices, including sitting meditation and yoga.

What has their research found?

One key study involved 26 people with high levels of perceived stress. After an eight-week regimen of MBSR, brain scans showed the density of their amygdalae decreased, and these brain changes correlated to lower reported stress levels.

Building on this, Lazar and colleagues designed a study that focused on 26 people diagnosed with generalized anxiety, a disorder marked by excessive, ongoing, and often illogical anxiety levels. The researchers randomized participants to either practice MBSR or receive stress management education. These participants were compared to 26 healthy participants.

In this first-of-its-kind research, participants were shown a series of images with angry or neutral facial expressions while their brain activity was gauged using functional MRI imaging. At the beginning of the study, anxiety patients showed higher levels of amygdala activation in response to neutral faces than healthy participants. This suggests a stronger fear response to a nonthreatening situation.

But after eight weeks of MBSR, MRI imaging showed increased connections between the amygdala and the prefrontal cortex, a brain area crucial to emotional regulation. The amygdalae in participants with generalized anxiety no longer displayed a fear response to neutral faces. These participants also reported their symptoms had improved.

“It seems meditation helps to down-regulate the amygdala in response to things it perceives to be threatening,” Lazar says.

How can meditation benefits help us in daily life?

Lazar believes training your brain to stop and notice your thoughts in a slightly detached way can calm you amidst the muddle of work deadlines, family friction, or distressing news.

“That’s one of the biggest translations” of meditation to everyday benefits, she says. “The person or situation that is stressing you out won’t go away, but you can watch your reactivity to the situation in a mindful, detached way, which shifts your relationship to it.”

“It’s not indifference,” she adds. “It’s sort of like a bubble bursting — you realize you don’t need to keep going on this loop. Once you see that, it totally shifts your relationship to that reaction bubbling through your brain.”

Want to try meditation — or expand your practice?

Haven’t tried meditating? To get started, Lazar recommends the Three-Minute Breathing Space Meditation. This offers a quick taste of meditation, walking you through three pared-down but distinct steps. “It’s simple, fast, and anyone can do it,” she says.

Simple ways to expand this basic approach are:

• adding minutes, just as you might for exercise
• meditating outdoors
• pausing to notice how you feel after you meditate.

“Or try either doing a longer session or short hits throughout the day, such as a three-minute breathing break four to five times a day,” Lazar suggests.

Another way to enhance your practice is to use ordinary, repetitive moments throughout the day — such as reaching for a doorknob — as a cue to pause for five seconds and notice the sensation of your hand on the knob.

“As you walk from your office to your car, for instance, instead of thinking of all the things you have to do, you can be mindful while you’re walking,” Lazar says. “Feel the sunshine and the pavement under your feet. There are simple ways to work meditation into each day.”

Looking for gifts to give or donate this year? Climate-conscious gifts come in many guises. They may directly support our environment, for example, or aim to reduce fossil fuel use and electronic, textile, and food waste. Or they might offer enjoyable, creative ways to connect, reuse, and recycle — and possibly even regift.

“Our purchases and choices impact our climate and planet,” notes Dr. Wynne Armand, a physician and associate director of the Massachusetts General Hospital Center for the Environment and Health. Small steps like these do help, she says, even when the complex issues of climate change leading to health-compromising pollution, extreme weather, and a stressed planet feel so large and overwhelming.

“Unquestionably, we need bold, strong leaders to seek policy changes that address these problems at a systems level. But, as individuals we can make a difference through small steps,” says Dr. Armand. “Our choices help drive cultural and market shifts that hopefully push our neighbors, businesses, and policy leaders in the right direction.”

Four climate-conscious principles for gifting

• Channel the 5 Rs. Refuse, reduce, reuse, repurpose, and only then recycle. Say no to excess. Comic sections from print newspapers or beautiful images from last year’s calendars or magazines make great envelopes and gift wrap. If you’re choosing clothes, consider buying upcycled clothing or at resale shops, as appropriate.
• Beware of greenwashing. Eco-consciousness is big business, and the benefits of what you buy may be questionable. If you have a small lawn that needs infrequent maintenance, says Dr. Armand, keeping a trusty (albeit gas-fueled) mower could be a better choice for the planet than buying an electric mower, when factoring in upstream costs of natural resources and the carbon footprint required to manufacture and ship the new — and toss out the not-so-old. (Alternatively, maybe it’s time to replant that lawn with wildflowers and vegetables?)
• Skip what’s not needed. A new backpack crafted from water bottles? Another sweater to add to a closetful? If there’s no apparent need, think twice about purchases.
• Double down on experiences and connection. Think concert tickets, museum passes, or energetic options like rock-climbing gym passes and outdoor skills classes. “Gifts of experience are great, especially for people who already have all they need. If you buy for two or try a skills swap you also get to enjoy that time together,” says Dr. Armand.

25 climate-conscious gifts

Below are 25 suggestions for climate-conscious giving intended to work with many budgets.

Small but mighty climate-conscious gifts

1. Soft, warm sweaters, thick socks, or puffer vests can help people turn down the heat, saving energy resources and money.

2. Rechargeable batteries reduce materials and packaging waste.

3. An electric kettle, induction hot plate, or toaster oven can help limit indoor pollutants from gas stoves.

4. Perfectly Good Food: A Totally Achievable Zero Waste Approach to Home Cooking aims to pare back food waste and is available online.

5. Shop local artisans and craft fairs rather than buying online.

6. Plants brighten any room and help scrub the air: choose easy-care varieties, such as succulents, colorful coleus, and some herbs.

7. Protect the natural world: birds, bees, and other insects could use your help. Consider a small bird feeder that attaches to a window, a bee house, gardening tools, or seeds for a pollinator garden of colorful flowers.

8. Donate to national or worldwide climate or environmental organizations, local green spaces, and local conservation groups.

9. Gift green bonds for companies that support renewable energy — do your research, though, because greenwashing can be an issue.

10. Secret gifter-giftee swaps with large groups save sanity and throttle back waste.

Bigger splurges on climate-conscious gifts

11. When appliances reach the end of useful life, consider replacing gas stoves, water heaters, washers, dryers, and similar items with electric versions.

12. Plan a week of nearby tours and events with friends or family instead of flights and faraway travel.

13. Gift clothes and tools to enjoy the natural world: for example, warm, waterproof clothing and hiking boots, cross-country skis or skates, good binoculars for bird-watching.

14. Composters (or a weekly composting service subscription) recycle food scraps and organic waste into soil-enriching “black gold.”

15. Electric bikes may be a boon if they reduce reliance on vehicles using fossil fuels.

16. Help fund energy-efficient heat pumps or renewable solar energy.

17. Substantial donations and sustaining donor gifts to climate-conscious organizations can help in many ways.

No-cost climate-conscious gifts

18. Offer to gather information on big-ticket items in the big splurges section, including state and federal rebates and 0% loans for heat pumps, energy-efficient furnaces, solar panels, and energy-efficient appliances.

19. Teach a skill one-on-one, such as home repair, skating, chess, training for a mud run, knitting, cooking, orienteering, or gardening, or organize skills swaps with friends.

20. Gift the human power needed to replant portions of a lawn with vegetables or pollinator plants, or make a rain garden (note: automatic download) to help divert storm water.

21. Combine a no-cost reminder of the environmental benefits of no-mow May and leave the leaves campaigns with an offer to help peel back these layers come spring.

22. Friends often want to gift one another — costly generosity that can prompt last-minute candle-buying. As an alternative, gather a small group of friends for a clothing, accessories, and candle swap of new, never-took-the-price-tag-off, nearly new, and well-loved items.

23. Offer a DIY nature or bird walk for two. Try the free Pl@ntnet and Merlin apps if you can’t tell a pin oak from a petunia or a robin from a California condor.

24. If you buy for a ton of people, buy in bulk and figure out how to parcel it out in more sustainable packaging.

25. Make dinner, fudge, or another treat with friends — not completely free, but always a great way to gather your community.
