Getting your kid to bed at night is one of the most difficult things that you'll ever have to do. Most kids are so full of energy that they will tire you out before they are halfway through their store of energy. An easy way to encourage them to get into bed is to give in and allow some iPad screen time. However, it is really not a good idea.

Researchers at Arizona State University carried out a study with 547 kids between the ages of 7—9. Their parents tracked how much screen time the kids were allowed along with their sleeping habits. They also had the kids wear wristwatches that could help researchers keep track of how long the kids were sleeping.

The study found that kids who are not allowed screen time before bed slept 23 more minutes every week and also went to sleep about 34 minutes earlier than their iPad—using peers. Although that might not seem like that much more time, quality of sleep is very important in children's development.

The 2018 National Youth Risk Behavior Survey concludes that good—quality sleep can influence a child's life in many ways, including affecting grades. Students with an "A" average slept for 30 or more minutes per night than those with a "D" or "F" average. Of course, getting to sleep on time and sleeping enough help contribute to improved performance in school.

As hard as it is, it's really important not to give in and hand over an iPad to a child who is about to go to bed. Just like it's important for adults to go to sleep without any e—devices, it's more important for kids. The one comforting thought is that finally they will kick this habit, and soon you will have to worry about waking them up as teenagers.

After numerous warnings over the years, you thought coffee probably had a negative effect on your health? Perhaps the drink is not so bad after all.

The new study, conducted by the National Cancer Institute (NCI), has been published and suggests that coffee does not have a harmful effect on your health. Researchers suggest, based on data examined, older adults who drink a lot of coffee, have a lower risk of death when compared to their non-drinking coffee peers.

The team of researchers conducting the study analyzed data on 400,000 U.S. men and women, aged 50 to 71 years; the individuals had participated in the NIH-AARP Diet and Health Study. This study started in 1995﹣1996 and was tracked until the day a participant passed away, or Dec. 31, 2008.

According to a press release on the report, researchers shared that coffee drinkers are “less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was not seen for cancer.”

Results indicated participants that drank three or more cups of java a day reduced their risk of death by 10percent. Based on the findings that both caffeinated and non-caffeinated coffee found similar results, researchers are thinking caffeine is not the protective ingredient(原料), although which ingredient in coffee might be, they are not sure.

Researchers indicate that despite these observational findings，they caution it is not clear whether or not drinking coffee actually extends life expectancy.

“Coffee is one of the most widely consumed drinks in America，but the association between coffee consumption and risk of death has been unclear. We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes,” said Neal Freedman, Ph. D. , Division of Cancer Epidemiology and Genetics, NCI.

“Although we cannot infer a relationship between coffee drinking and lower risk of death, we believe these results do provide some comfort that coffee drinking does not adversely affect health,” Freedman said.

Dr. Cheryl Williams, a registered dietician, told ABC News, “Overall, more research needs to be done to truly understand the compounds in coffee and their biological activity and effect on health,” said Williams.

We all do little things to boost the way we feel and think throughout the day. Something as simple as taking a walk or eating a piece of chocolate can brighten your mood almost instantly, thanks to certain chemical reactions that occur in the brain. 【小题1】If you're going through something complex, you need a more permanent practice.
