|STOCKHOLM jordan 6 wheat 2017 , Aug. 27 (Xinhua) -- When children enter their teens they need more sleep, but that can be hard to combine with busy school schedules.
At Smedhagsskolan, a lower and middle school north of Stockholm, students get to sleep in every day, and this has improved their performance, Swedish public television broadcaster SVT reported Sunday.
Feeling good improves school performance and getting a good night's sleep is especially important for teenagers who need about nine hours of sleep a night. But because the biological clock changes as children enter puberty jordan 6 wheat , many of them go to bed later in the evening. As a result, they have a harder time getting up in time for school.
According to psychiatrist Anders Hansen, many teenagers prefer to sleep from midnight to about nine in the morning.
"The fact that the circadian rhythm changes combined with a need for more sleep causes many to have a hard time getting up in the morning," Dr. Hansen told SVT Vetenskap, a science program.
At Smedhagsskolan they solved the problem by letting students sleep in. Ten years ago they started letting students start at 9 a.m., instead of an hour earlier.
"Student performance has gone up and if they come to class on time they learn more air jordan 6 alternate for sale , and then the results go up," Lolitha Nilsson, principal at Smedhagsskolan, told SVT.
According to Dr. Hansen, there is a strong connection between getting a good night's sleep and learning.
"Sleep is extremely important for physical and psychological well-being. If you look at the brain you can see that there is a transfer from the short-term memory to the long-term memory during the night. This is often called consolidation. That is why sleep is extremely important for learning," he said.
Physical activity is also a factor that affects school performance. At Smedhagsskolan students who are early risers can participate in a physical activity at school instead of sleeping in.
"The school also offers students different activities in the morning such as boxing For Sale Mens Air Jordan 6 Wheat Golden Harvest 384664-705 , basketball, jogging and soccer that help the students get a good start to the day before school starts," Ms. Nilsson said.

Chinese students at Hunan University have invented a system to increase the electricity generation of small and medium-sized hydropower stations during dry seasons.
"Traditional hydroelectric power stations have a fixed water flow requirement cheap air jordan 6 wheat mens , which means electricity outputs drop dramatically during the dry season," said Lyu Mingsheng, one of the students.
The invention fixes the current situation where power output is directly proportional to river flow, allowing small and medium-sized hydropower plants to maintain output throughout all seasons, according to Lyu.
Improving generating capacity is expected to reduce the number of hydropower plants needed in the future, therefore lessening their effect on the environment.
"The new technology will transform the dam construction in China air jordan 6 retro wheat mens , making it more environment-friendly," he said.
Lyu cited official figures published in 2013 which stated China had more than 45,000 hydropower stations in rural areas, with the total installed capacity exceeding 65 million kilowatt (kW).
If the new system was applied to all of these stations, the total installed capacity would increase by 19.5 million kW, almost equivalent to the output of the Three Gorges Dam which is 22.4 million kW air jordan 6 wheat mens online , Lyu added.
The core technology has received 10 national patents and several companies have signed cooperation agreements with Lyu's team.
