Stress

The Big Picture

Most of these speakers refuse to treat stress as simply harmful. Stress scientist Elissa Epel tells Andrew Huberman that a healthy stress response is something to welcome: we mount a response, we recover, and no harm is done [3]. Cardiologist Dr. Tara Narula tells Mel Robbins that stress itself isn't bad and that some stress pushes us to grow, but that there's a tipping point where it becomes harmful [5]. Harvard physician Dr. Aditi Nerurkar puts it plainly: "The goal of life is not to live a life with zero stress. It is in fact biologically impossible." [6] Stanford psychologist Alia Crum gives the reason stress exists at all: "we stress because we care" [1].

The trouble the speakers describe is a response that does not end. Epel says the modern problem is that we keep the response running long after the event has passed, by replaying it mentally [3]. Narula says modern humans trigger it all day long over bills, school problems, difficult bosses and bad news, and it often stays on [5]. Bruce Lipton, on The School of Greatness, compares it to Cold War air-raid drills and says today's stress never gives the all clear [8]. Alongside that runs a second theme: what you believe about stress changes what it does to you [1][4][9].

Where the Experts Agree

• The stress response is a survival mechanism. Epel says that survival response is the reason we're still here [3]. Narula describes escaping a lion: heart rate, blood pressure and breathing rise while digestion, reproduction and growth shut down, and then the response turns off [5]. Lipton says stress hormones prepare the body to flee, like our ancestors running from a saber-tooth tiger [8].
• The harm comes when it stays on. Narula says the signal of a problem is when the response doesn't shut off, and that chronic low-grade stress is the bigger concern [5]. Huberman says the key is being able to turn it off, and his rule of thumb is that once stress prevents good sleep, it has moved from acute to chronic [2]. Epel says, "Our thoughts are the most common form of stress." [3]
• Mindset changes the response. Kelly McGonigal describes a study in which those with very stressful lives who strongly believed stress was harmful had a 43% higher risk of dying from any cause over the next decade [4]. Huberman cites Crum's research: people taught that adrenaline sharpens thinking perform better, and people taught that stress harms cognition perform worse [9]. Crum and Huberman agree that stressing about stress amplifies it [1].
• Stress is a mismatch of demands and resources. Epel says it describes moments when we feel overwhelmed because the demands seem greater than our resources [3]. Marc Brackett defines stress as too many demands and not enough resources [7].
• Stress can be put to use. Crum's third step is to utilize the stress response to achieve a goal rather than spending energy trying to get rid of it [1]. Huberman calls stress the most powerful smart drug there is, in the form of fear of failure and looming deadlines [2].

Where They Differ

They differ on whether stress should be sorted into good and bad. Epel says "stress" has to be broken down into good and bad stress and into acute and chronic stress [3]. Nerurkar separates unhealthy, maladaptive stress from healthy, manageable stress that drives you forward [6]. McGonigal, asked by Howes how to tell good stress from bad stress, says there's no such thing, and warns that labeling hardship as "bad stress" can lead to harsh conclusions about yourself [4].

They also differ on how far mindset goes. Huberman argues that consuming information that frames stress as growth-promoting changes what your own stress does to you [9]. McGonigal is careful not to oversimplify her own work into the idea that stress isn't bad unless you believe it is; she calls stress a paradox and says we rarely get to choose it [4]. Brackett points to a limit of another kind: deep breaths won't fix stress if your plate is simply too full, so you either accept it or delegate [7].

The accounts of the body pull in different directions too. Lipton says behavior divides into growth and protection, "You cannot do both at the same time," and that under stress the immune system is switched off and we become less intelligent [8]. Huberman says stress narrows visual attention, which helps parse time more finely and process information faster, almost like a superpower [1]. His episode on stress tools is described as explaining why short bursts help immunity, and he says people often get sick on vacation because the adrenaline response crashes and immunity crashes with it [2].

Practical Takeaways

• Follow Crum's three steps: acknowledge the stress and own it, welcome it because it points to something you care about, and utilize it toward that goal [1].
• Watch for the signs Narula lists that the response has not shut off: clenched muscles, shallow breathing, a faster heart rate and a mind that keeps cycling [5].
• Use sleep as a marker: Huberman says once stress prevents good sleep, it has moved from acute to chronic [2].
• Try Nerurkar's test: think back to how you were in 2016 or 2019 and ask whether your sleep, socializing, productivity, mood, energy or body have changed [6].
• Name the feeling precisely before choosing a response, since Brackett separates stress from anxiety, pressure, fear and overwhelm [7].
• If your plate is simply too full, accept it or delegate [7].
• Notice when the stress is coming from replaying an event in your mind after it has passed; Epel says the first step is awareness of how our minds work [3].
