The words
Everyone knows that [good / goodness] sleep is important for our health. Not everyone knows how important it is to sleep in the [darkly / dark] . A new report says sleeping with the light [in / on] could be [bad / badly] for our health. Researchers say turning off the light when we sleep helps to keep [about / away] diabetes and heart disease. Sleeping with the light on could increase the risk [of / to] getting these diseases. The researchers said around 40 per cent of people sleep with some sort [of / off] artificial light. They said even light from a television or alarm clock could [effect / affect] our health. They added that the worst thing to sleep with is a [main / mainly] light. Sleeping in the dark is more difficult for people who live in cities, where there is a lot of outdoor light [on / at] night.

The researchers [are / be] from the Northwestern University Feinberg School of Medicine in Chicago, USA. The lead researcher, Dr Phyllis Zee, is an [export / expert] in sleep medicine. She said it is healthier for [us / them] to turn off all lights when we sleep. Her team conducted a study [to / of] the blood sugar [levels / rebels] of 20 people after nights of sleep. The people who [slept / sleeping] with a light on had higher blood sugar levels the next morning compared to those who slept [on / in] total darkness. Dr Zee said this is because light stimulates brain [active / activity] , which raises blood sugar levels. She said there are three things we can do to [reduce / deduce] the risk of illness: turn off the lights, never sleep with white or blue light; and use a blackout curtain or wear [an / a] eye mask.
