问题     If you’re like many people, you may have decided that you want to spend less time【C1】________at your phone. It’s a good idea: an increasing body of【C2】________suggests that the time we spend on our smartphones is【C3】________with our sleep, self-esteem, relationships, memory, attention spans, creativity, productivity and problem-solving and decision-making【C4】________  .
    【C5】________there is another reason for us to rethink our 【C6】________ with our devices. By chronically raising levels of Cortisol, the body’s main stress hormone, our phones may be【C7】________ our health and shortening our lives.
    Until now, most discussions of phones’ biochemical effects have focused on dopamine, a brain chemical that helps us【C8】________ habits—and addictions. Like slot machines, smartphones and apps are explicitly designed to【C9】________dopamine’s release, with the【C10】________of making our devices difficult to put down. This manipulation of our dopamine systems is【C11】________many experts believe that we are developing behavioral【C12】________to our phones. But our phones’ effects on Cortisol are potentially even more【C13】________ .
    Cortisol is our primary fight-or-flight hormone. Its release triggers【C14】________ changes, such as spikes in blood pressure, heart rate and blood sugar, that help us react to and【C15】________ acute physical threats. These effects can be life-saving if you are actually in physical【C16】________—like, say, you’re being charged by a bull. But our bodies also release Cortisol in response to emotional stressors where an increased heart rate isn’t going to do much good, such as checking your phone to find an angry email from your boss.
    The good news is that if we break this anxiety-driven cycle, we can【C17】________our Cortisol levels, which in turn may both【C18】________our short-term judgment and lower our【C19】________for long-term stress-related health problems. To make your phone less stressful, start by turning 【C20】________ all notifications except for the ones you actually want to receive.
