Practice Reading: Multiple Choice, Single Answer ID: #43395 Melatonin
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Most people think of melatonin as a natural nod-off aid. Experts strongly urge people to consult their doctor or a sleep specialist before taking melatonin, in part because the supplement does not address many underlying health problems that may be disrupting sleep. Instead of a lights-out trigger, melatonin acts more like a dimmer switch, turning the day functions off and switching night functions on. So taking a melatonin supplement is sort of like taking a dose in sunset, tricking your body into feeling like it’s nighttime. It doesn’t put you to sleep as much as it tells the body that it’s time to sleep.
