Obesity rates are much higher among those who sleep for less than six hours a night, in part because sleep deprivation interferes with how the brain and body use energy.
First, your brain is temporarily taken over by the promise of reward. At the sight of that strawberry cheesecake, your brain launches a neurotransmitter called dopamine from the middle of your brain into areas of the brain that control your attention, motivation, and action. Those little dopamine messengers tell your brain, “Must get cheesecake NOW, or suffer a fate worse than death.
The stress response is more than a basic survival instinct. It is built into how humans operate, how we relate to one another, and how we navigate our place in the world. When you understand this, the stress response is no longer something to be feared.
Studies of brain activation confirm that as soon as you give participants permission to express a thought they were trying to suppress, that thought becomes less primed and less likely to intrude into conscious awareness. Paradoxically, permission to think a thought reduces the likelihood of thinking it.
It’s forgiveness, not guilt, that increases accountability. Researchers have found that taking a self-compassionate point of view on a personal failure makes people more likely to take personal responsibility for the failure than when they take a self-critical point of view.
Even in circumstances of great suffering, human beings have a natural capacity to find hope, exert choice, and make meaning. This is why in our own lives, the most common effects of stress include strength, growth, and resilience.
I will” and “I won’t” power are the two sides of self-control, but they alone don’t constitute willpower. To say no when you need to say no, and yes when you need to say yes, you need a third power: the ability to remember what you really want.
A tired operator and an energized monitor create a problematic imbalance in the mind. As the monitor searches for forbidden content, it continuously brings to mind what it is searching for. Neuroscientists have shown that the brain is constantly processing the forbidden content just outside of conscious awareness. The result: You become primed to think, feel, or do whatever you are trying to avoid.
Desire is the brain’s strategy for action. As we’ve seen, it can be both a threat to self-control and a source of willpower. When dopamine points us to temptation, we must distinguish wanting from happiness. But we can also recruit dopamine and the promise of reward to motivate ourselves and others. In the end, desire is neither good nor bad – what matters is where we let it point us, and whether we have the wisdom to know when to follow.
It used to puzzle me: Why do companies advertise during such depressing programming? Do they really want viewers to associate their products with the horror stories that fill the nightly news? And who is going to be in the mood for a department store sale after hearing about a brutal murder or the threat of a terrorist attack? It turns out I might be, and you might be, too, thanks to a psychological phenomenon called terror management.
We may try to push thoughts out of our minds, but the body gets the message anyway. And just as trying to suppress sad and self-critical thoughts makes depression worse, studies show that thought suppression increases the symptoms of serious anxiety disorders such as post-traumatic stress disorder and obsessive-compulsive disorder.
Your Body Was Born to Resist Cheesecake.
Restores nervous system balance Processes and integrates the experience Helps the brain learn and grow Even though your body is calming down, you still feel mentally charged. You replay or analyze the experience in your mind, or want to talk to others about it. A mix of emotions are usually present, along with a desire to make sense of what happened.
It turns out that people with a stress-is-enhancing mindset are more likely to be optimists, but the correlation is small. In addition to optimism, two other personality traits seem to be associated with a more positive view of stress: mindfulness and the ability to tolerate uncertainty.
To say no when you need to say no, and yes when you need to say yes, you need a third power: the ability to remember what you really want.
When you stop trying to control unwanted thoughts and emotions, they stop controlling you.
When adults are randomly assigned to reduce their daily step count, 88 percent become more depressed. Within one week of becoming more sedentary, they report a 31 percent decline in life satisfaction. The average daily step count required to induce feelings of anxiety and depression and decrease satisfaction with life is 5,649. The typical American takes 4,774 steps per day. Across the globe, the average is 4,961.
We are used to believing that we need to change everything about our lives first, and then we will be happy, or healthy, or whatever it is we think we want to experience. The science of mindsets says we have it backward. Changing our minds can be a catalyst for all the other changes we want to make in our lives.
Stress may be a natural byproduct of pursuing difficult but important goals, but that doesn’t mean every stressful moment is rich in meaning. And yet even when the stress we’re under doesn’t seem inherently meaningful, it can trigger the desire to find meaning – if not in this moment, then in the broader context of our lives.
When you exercise, you provide a low-dose jolt to the brain’s reward centers.
