35 minutes of walking a day reduces the risk of stroke

28.09.2018

Even a small amount of physical activity - such as walking for at least four hours a week or swimming two to three hours a week - helps reduce the risk of stroke.

The study by scientists from the University of Gothenburg (Sweden) involved 925 people who had a stroke. The average age of the subjects is 73 years. 80% had a "mild" stroke. To determine participants' physical activity, they were asked how much they moved or exercised in their spare time prior to their stroke.

Light physical activity was defined as walking at least four hours per week. Moderate physical activity - like swimming, brisk walking or running two to three hours a week. 52% of people noted that they were physically inactive before the stroke.

Importantly, participants reported being physically active after their stroke, which may have affected memory. Therefore, the results of the study may have small "errors".

The researchers found that people who exercised on a light or moderate "mode" predominantly suffered a "mild" stroke, while a moderate or severe stroke affected less active people. Of the 481 people who moved little, 354 - 73% - experienced a "moderate" stroke. Of the 384 people who were engaged in light physical activity, 330 people, or 85%, had the same stroke strength as the previous ones. And 53 out of 59 people who led a "moderately" active lifestyle, accounting for 89%.

The authors of the study noted that the difference in physical activity did not explain the large difference in stroke severity. They also added that the study does not prove that physical activity reduces stroke severity; it only reveals some relationships.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Parents lose years of sleep when their baby is born 30.01.2024

The birth of a child is a period of change, full of joy and challenges, and has a significant impact on the lives of parents. They are forced to adapt to a new role, devoting themselves entirely to caring for the baby. However, according to a study by scientists from the University of Warwick, this leads to significant sleep loss for parents.

There is no doubt that the birth of a child is a wonderful event, but it is also a challenge for parents that can affect their health and well-being. Research of this kind helps to recognize the importance of support and care for new parents so that they can successfully cope with the challenges of parenthood.

Scientists tracked 4600 married couples for seven years and concluded that parents lose up to six years of healthy sleep after the birth of a child.

In the first year after the birth of a child, mothers lose an average of one hour of healthy sleep daily, and for fathers this amount is 15 minutes. Over time, losses in mothers decrease to 20 minutes, while in fathers they remain stable.
