Children with TVs in their room sleep less

03.09.2008
Middle school children who have a television or computer in their room sleep less during the school year, watch more TV, play more computer games and surf the net more than their peers who don't – reveals joint research conducted by the University of Haifa and Jezreel Valley College.

The research, conducted by Prof. Yael Latzer and Dr. Tamar Shochat of the University of Haifa and Prof. Orna Chishinsky of the Jezreel Valley College, examined 444 middle school pupils with an average age of 14. The children were asked about their sleep habits, their use of computer and television, and their eating habits while watching TV or using the computer.

The study participants reported an average bedtime of 11:04 P.M and wake-up time of 6:45 A.M. On the weekends, the average bedtime was somewhat later – at 1:45 A.M. and wake-up much later – at 11:30 A.M. Those children with TVs or computers in their room went to sleep half an hour later on average but woke up at the same time.

According to the study, middle school pupils watch a daily average of two hours and 40 minutes of TV and use their computer for three hours and 45 minutes. On weekends, they watch half an hour more TV than during the rest of the week and use their computers for four hours. Children with a TV in their room watch an hour more than those without and those with their own computer use it an hour more than their peers.

A fifth of pupils said they ate in front of the TV set on a regular basis, while 70 percent said they did so only occasionally. Only 10% reported never eating in front of the TV. Computers were considered to be a less attractive eating place, with only 10% eating in front of the computer on a regular basis, 40% occasionally, and half never eating there.

According to the researchers, there is a direct connection between exposure to the media and eating in front of the TV or computer; the more a child watches television or uses the computer, the greater the chance he will eat in front of the screen.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
