Even though humans sleep away about one-third of their lives, sleep science is relatively new. But the latest results show that sex trumps sport as a sleep aid.
These are just some of the results presented at the annual convention of the German Sleep Society (DGSM) in Kassel, where 1,500 scientists recently gathered to discuss factors contributing to healthy sleep.
“Earlier, people thought that sleeping disorders were the result of other diseases. Today, we know that it’s the opposite and many diseases get worse or exist because the patient sleeps poorly,” says Geert Mayer, head of the DGSM. “Cardiological and circulatory problems are often precipitated by unsound sleep lasting for a longer period. We’ve also established a significant connection between sleeping disorders and diseases like dementia or Parkinson’s.”
One study found that 69 percent of Parkinson’s patients have had sleeping disorders in the past, which often start in childhood.
“About 40 percent of all small children have sleeping disorders. They usually disappear over time, but it’s not unusual for older children to suffer from daytime sleepiness. About one-third of pre-teens and teens are affected,” said Alfred Wiater, the head of a pediatrics clinic in Cologne.
Wiater recommends reducing a child’s media consumption to promote sleep. He says exhaustion in children is no small matter.
“Most children with sleeping disorders have some kind of mental disturbances, like fears, depression or hyperactivity,” he said.
“There are no hard and fast rules. Not even a rule of thumb,” Mayer said. “We often get old people who want their eight hours of sleep. But their body doesn’t need that much. Others complain that they only feel well rested after nine hours of sleep, which is also completely normal.”
To ensure sleep is recuperative, researchers recommend a healthy diet and plenty of exercise, but it is best to take things easy before bedtime.
“Exercise and other stimuli sends out hormones that keep the body awake internally,” Mayer said.
Though there is one exception to the rule — sex.
“We suspect there are positive benefits because the body gets stimuli, but then relaxes,” Mayer said.
A fire caused by a burst gas pipe yesterday spread to several homes and sent a fireball soaring into the sky outside Malaysia’s largest city, injuring more than 100 people. The towering inferno near a gas station in Putra Heights outside Kuala Lumpur was visible for kilometers and lasted for several hours. It happened during a public holiday as Muslims, who are the majority in Malaysia, celebrate the second day of Eid al-Fitr. National oil company Petronas said the fire started at one of its gas pipelines at 8:10am and the affected pipeline was later isolated. Disaster management officials said shutting the

US Vice President J.D. Vance on Friday accused Denmark of not having done enough to protect Greenland, when he visited the strategically placed and resource-rich Danish territory coveted by US President Donald Trump. Vance made his comment during a trip to the Pituffik Space Base in northwestern Greenland, a visit viewed by Copenhagen and Nuuk as a provocation. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told a news conference. “You have under-invested in the people of Greenland, and you have under-invested in the security architecture of this
Japan unveiled a plan on Thursday to evacuate around 120,000 residents and tourists from its southern islets near Taiwan within six days in the event of an “emergency”. The plan was put together as “the security situation surrounding our nation grows severe” and with an “emergency” in mind, the government’s crisis management office said. Exactly what that emergency might be was left unspecified in the plan but it envisages the evacuation of around 120,000 people in five Japanese islets close to Taiwan. China claims Taiwan as part of its territory and has stepped up military pressure in recent years, including
