The researchers looked at men and women sleeping less than or equal 5 hours a night to see if their risk of having hypertension was any higher than men and women getting the recommended 7 hours or more of sleep a night. Among other problems increased hypertension does increase the risk of cardiovascular problems.
Some previous studies have indicated that sleep deprivation is also associated with an increased risk of hypertension. However that research was based on self-reported diagnosis of hypertension, and had no gender-specific analysis.
The University of Warwick led research team looked at data from “The Whitehall II Cohort” which studied volunteers from 20 London-based civil service departments. There were a total of 6,592 participants (4,199 men and 1,567 women). The Warwick team defined hypertension as blood pressure equal to or higher than 140/90 mm Hg or if the subject made regular use of antihypertensive medications.
The researchers found that the those women in the study group who slept less than or equal to 5 hours a night were twice as likely to suffer from hypertension than women who slept for the more recommended seven hours or more a night. The researchers found no difference between men sleeping less than 5 hours and those sleeping 7 hours or more.
Professor Francesco Cappuccio from the University of Warwick’s Warwick Medical School led the research he declared that women sleeping les than 5 hours a night should try to get more sleep as:
“Sustained sleep curtailment, ensuing excessive daytime sleepiness, and the higher cardiovascular risk are causes for concern. Emerging evidence also suggests a potential role for sleep deprivation as a predictor or risk factor for conditions like obesity and diabetes.”

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
