Amazing Fact! Your Genes Determine Your Quality of Sleep

"Our study suggests that many of the genes important for sleep in animal models may also influence sleep in humans and opens the door to better understanding of the function and regulation of sleep," Dashti added.

Experiencing problems like insomnia or hypersomnia could be genetic, say researchers who identified 76 new gene regions associated with the time a person sleeps.

It is well known that regularly getting adequate sleep — 7 to 8 hours per night — is important for health, and both insufficient sleep — 6 or fewer hours — and excessive sleep — 9 hours or more — have been linked to significant health problems.

Family studies have suggested that 10 to 40 per cent of variation in sleep duration may be inherited, and previous genetic studies have associated variants in two gene regions with the sleep duration.

The study from the Massachusetts General Hospital (MGH) in Boston, US, analysed genetic data from more than 446,000 participants, who self-reported the amount of sleep they typically received.

The study identified 78 gene regions — including the two previously identified — as associated with sleep duration.

While carrying a single gene variant influenced the average amount of sleep by only a minute, participants carrying the largest number of duration-increasing variants reported an average of 22 more minutes of sleep, compared with those with the fewest.

This was comparable to other well-recognised factors that influenced sleep duration.

“While we spend about a third of our life asleep, we have little knowledge of the specific genes and pathways that regulate the amount of sleep people get,” said Hassan Saeed Dashti from MGH.

“Our study suggests that many of the genes important for sleep in animal models may also influence sleep in humans and opens the door to better understanding of the function and regulation of sleep,” Dashti added.

The study, published in Nature Communications journal, also found shared genetic links between both short and long sleep duration.

It also found factors such as higher levels of body fat, depression symptoms and fewer years of schooling, implying negative effects from both too little and too much sleep.

While short sleep duration was genetically linked with insomnia and smoking, long sleep duration was linked with ailments such as schizophrenia, Type-2 diabetes and coronary artery disease. (IANS)

East African Countries Set to Ban Skin-Lightening Products Containing Hydroquinone

If bans are not backed by enforcement, they will have little effect on the use of the high demand skin-lightening products, despite the risk to health

East African countries are set to ban skin-lightening products that contain hydroquinone, a medical agent linked to health problems when used in high concentrations. The East African Legislative Assembly last week passed a resolution calling for a region-wide ban on the manufacturing and importation of products containing hydroquinone.

At a beauty parlor in Arusha, 52-year-old Rose Mselle has been using skin-bleaching products since she was a teenager. She says women like her want to be beautiful. “And in the process of looking for beauty, or for our skin color to shine, we use things that we shouldn’t,” she added.

At a nearby market, 32-year-old clothing vendor Janet Jonijosefu used skin-lightening products that contain hydroquinone, a medical agent used to treat dark spots, for years. She stopped after her skin became fragile.

She said the beauty products containing hydroquinone badly affected her skin. She started developing patches on her face. She went to the doctor and was advised to stop using products containing hydroquinone and instead use aloe vera.

Skin-lightening products often use high concentrations of hydroquinone, which can cause skin problems or become toxic when mixed with other bleaching chemicals.

Ghana, Ivory Coast, Kenya, Nigeria, Rwanda, and South Africa ban or regulate the agent in cosmetics. Tanzania bars imports. The East African Legislative Assembly last week passed a resolution on a region-wide ban of hydroquinone’s manufacture and importation.

Suzan Nakawuki, a member of the regional assembly from Uganda, noted that hydroquinone is not only used by women but also men. “We have seen men bleaching seriously even more than women,” she said. “But it’s becoming a problem. If we don’t regulate it, it is going to become very problematic.”

When used medically, hydroquinone can be an effective treatment for skin discoloration. Some East African lawmakers spoke out against a blanket ban. Aden Abdikadir, a lawmaker from Kenya, said he is concerned a blanket ban will cause “serious trade disruption” for cosmetics.

If signed by heads of state, the ban becomes law in all six East African Community states, which include Burundi, Kenya, Rwanda, South Sudan, Tanzania and Uganda.

Critics point out bans on hydroquinone have failed to stop smuggled products from being sold openly. Cosmetics labeled as having hydroquinone are on display at shops in Arusha.
