It was like she had jet lag, she says, without changing time zones. It’s not that Lewis doesn’t appreciate the merits of a good night’s sleep. She does. But when you’re trying to map what’s happening in a slumbering human’s brain, you end up making some sacrifices. “It’s this great irony of sleep research,” she says. “You’re constrained by when people sleep.”

The kind of words we choose to use can literary change our brain. A single word has enormous power to influence the expression of genes that regulate emotional and physical stress.

Researchers have discovered that when we use positive words like peace, love, and loving-kindness, we modify our brain functions by generally increasing cognitive reasoning and strengthening areas around our frontal lobes. Therefore, utilizing positive words more frequently than negative words can actually activate the motivation centers of the brain, prompting them into action.
