In a review of everything currently known about the topic, researchers recently developed a scientific model of how contemplative practices of various kinds may encourage better physical and psychological health. Published in Psychological Review, one of the flagship academic journals of the American Psychological Association, this new model advances our understanding of the adverse effects of stress and what can be done to combat it.

The researchers note there are four primary stress-related states we all experience: (1) acute stress (example: arguing with a spouse), (2) moderate threat (example: working), (3) rest (example: watching TV), and (4) deep rest (the least studied of the four, but most beneficial). Although many believe that rest is our baseline, default state, the scientists in this article suggest that, in the United States (and, by extension, in other developed countries), most adults now spend most of their daytime hours in moderate threat arousal, which drains of us of the restorative energy we need to function at our best. In fact, considerable research conducted over many decades demonstrates that this level of chronic stress contributes to various physical and psychological health problems ranging from heart disease to immune suppression, from chronic pain to depression. Individuals from marginalized groups seem particularly likely to experience this degree of toxic stress, helping to explain some of the health inequities we observe in certain groups such as people of color and individuals with poor economic resources.

Whereas acute stress and moderate threat cause sympathetic nervous system activity, deep rest is characterized by the dominance of the parasympathetic nervous system. The parasympathetic nervous system basically calms us. The researchers in the Psychological Review article further speculate that deep rest may be uniquely restorative at a cellular level. In this way – though there are surely limits – deep rest may be physically and psychologically “healing.”

Although there may be several activities that promote deep rest and enhance the body’s restorative capacity, most emphasized in the article is how contemplative practices may play a unique role. As noted by the authors, “contemplative practices are mind-body exercises that are intentionally practiced to work toward inner well-being, psychological flourishing, and deep connection with self, the world, or a higher power.” Examples of such practices include deep prayer, chanting, meditation, yoga, Tai Chi, and Qigong.

To achieve deep rest, the researchers suggest that individuals must feel safe, and that contemplative practices provide unique opportunities for doing so, for several reasons. First, contemplative practices typically are conducted in safe spaces. Examples include intentionally secluded spaces, a harmonious environment, or a natural setting. A sensory component may further cue feelings of safety, such as when essential oils or incense are used. A tactical dimension of the practices may enhance their effects as well. For instance, slowly and rhythmically advancing prayer beads through one’s fingers may promote a sense of absorption through sensations of touch. Second, contemplative practices can be performed in a socially safe environment, including trusted teachers and fellow practitioners. Engaging in a practice in unison with others may evoke a sense of group belonging and sense of awe, adding to the benefits. Finally, contemplative practices may work to create a sense of safety through reduction of distressing thoughts, increase of bodily awareness, improved attentional capacity, and strengthened skills of emotional regulation. In these ways, contemplative practices may be particularly meaningful for those who often lack safety, especially those on the margins of society.

Most contemplative practices also encourage slowed and/or regulated breathing, either intentionally or as a result of the calming practice, providing another mechanism for achieving deep rest. In one study, for example, participants told to repeat prayers of either Ave Maria or a yoga mantra slowed their breathing rate to 6 breaths per minute, a rate other research has found to be linked with positive health outcomes. In fact, there is growing research evidence that long-term contemplative practice may change our baseline stress state and make it easier to slip into deep rest as well as deep, nonrapid, eye movement sleep, the stage of sleep that most restores us physically and psychologically.

In many locations in the world where chronic stress is highest, religious involvement is dropping, perhaps contributing to the increase in disorders we’re also observing in those places. Perhaps as a result, many individuals are trying contemplative practices on their own, implementing practices into their lives with the hope they will nurture higher well-being. This new model integrating what is known about contemplative practices, stress, and the body’s restorative capacity further validates the benefits of such practices, whether they occur within a community or whether they are practiced individually. For the average person, all of this may serve as a reminder that taking time to intentionally and deeply connect with one’s self, the world, or a higher power may be one of the most powerful things we can do to manage stress and attain holistic health.
