The Century of Celestial Superflares: A Phenomenon Worth Watching

Stars similar to the Sun produce a gigantic outburst of radiation on average about once every hundred years per star. Such superflares release more energy than a trillion hydrogen bombs and make all previously recorded solar flares pale in comparison. This estimate is based on an inventory of 56450 sun-like stars. It shows that previous

Optimal Timing: How Exercise Schedules Impact Your Health

The​ University‌ of ⁣Sydney researchers found that people with obesity who engage‌ in most⁢ of their​ daily physical activity‍ in the evening experience the greatest health benefits. This conclusion was drawn after studying the habits of 30,000⁣ individuals over an ⁢8-year period. The researchers used ⁢wearable device data to track the participants’ physical activity patterns.At any time of the day, whether it’s morning, afternoon, or evening, the ⁢researchers found that those who engaged in ⁢the ‌majority of‍ their aerobic moderate to vigorous physical activity ​had⁤ the‌ lowest⁣ risk of premature death and death from‍ cardiovascular disease. The time between ‌6pm and ​midnight seemed​ to be the⁤ most beneficial for this kind of ​physical ‍activity.

The frequency ⁣of moderate to vigorous physical activity in​ the evening, measured in short bouts of three minutes or more, was found to be more important than⁢ the​ total amount⁣ of physical activity done daily.

The study was conducted by researchers from⁣ the University’s Charles Perkins Centre.The findings were published in the journal Diabetes Care today.

Dr. ⁣Angelo Sabag,⁤ a Lecturer ​in Exercise Physiology at the University of Sydney, stated‍ that around two in three Australians have excess weight or obesity due to various societal factors. ⁢This increases their risk of⁢ major cardiovascular⁢ conditions‍ such as heart attacks, stroke, and premature death.

Dr. Sabag also mentioned that while exercise is not‌ the only solution⁤ to the obesity crisis, ⁤the‌ research suggests that⁢ people ⁢who can schedule their physical activity at specific times of the day may ‍be able to reduce ⁣some of ⁢these health risks.

Prior smaller‌ clinical trials have shown similar results.the type of ⁢physical activity, whether ​it was structured exercise ‌or not. Instead, we ‌specifically⁣ looked at ⁢continuous aerobic MVPA in bouts of 3 minutes or more. Previous research has suggested a strong connection⁣ between this type ‍of activity, glucose control, and reduced risk of cardiovascular disease compared to shorter, non-aerobic ⁣bouts.” Joint‌ first author Dr. Matthew Ahmadi emphasized.Dr Ahmadi, a National Heart ‌Foundation⁣ postdoctoral research fellow ‌at the Charles Perkins Centre, University of ⁢Sydney, explained that the activities tracked in the study ranged from power walking to climbing​ stairs,​ as well as structured exercises like running, ‍occupational labor, or even vigorous house cleaning. The study’s ⁤findings, although observational, ​support the original hypothesis based on previous research. This hypothesis suggests that‌ individuals⁣ with diabetes or obesity, who already have⁣ glucose intolerance in the late⁣ evening,‌ may be able​ to reduce‍ some of that intolerance and its associated effects.complications, from exercising⁣ in the evening.

The scientists utilized information from UK Biobank and included 29,836 adults over⁣ the age of 40 who ⁣were living with ‌obesity, ‍among ⁢whom 2,995 individuals‍ were also dealing ‌with Type⁣ 2 diabetes.

The participants were divided into morning, afternoon, or evening MVPA⁣ groups ​based ⁤on the time when they primarily ⁣engaged ⁢in their aerobic MVPA, which was measured by a wrist accelerometer worn continuously for 24 hours a day over a period of 7 days at ‍the beginning ‍of​ the study.

The researchers then connected health information (obtained ⁣from the National Health Services and National Records of Scotland) to ​track⁣ the health ⁢progress of the participants for 7 years.Over a span of 9⁢ years,⁢ researchers documented 1,425 deaths, 3,980 cardiovascular events, and 2,162‍ microvascular dysfunction events. In⁢ order to minimize ​bias, the researchers took into account factors such as age, gender, smoking, ⁢alcohol consumption, ‌fruit and vegetable intake, sedentary⁢ behavior, physical activity, education, medication usage, and sleep duration.​ They also ⁤excluded individuals with existing cardiovascular disease‍ and cancer. The researchers believe that the ​length⁢ of the study and additional sensitivity analysis enhance the validity of their⁢ results. However, due to the observational nature of the study, they ‌are⁢ unable to establish causation.This article discusses the importance of considering ​potential reverse causation, which is‌ the idea that some participants may have lower aerobic MVPA ‍levels due​ to an underlying or undiagnosed ⁤disease. Professor Emmanuel Stamatakis, ​the Director of the Mackenzie Wearables Research Hub at the Charles ⁤Perkins Centre and senior author⁤ on the paper, emphasizes the significance of the sophistication of studies in the wearables field, as they provide ​valuable insights into the most beneficial activity patterns for health. Wearable device-captured data allows researchers and ⁤practitioners to examine physical ​activity patterns in great detail, marking an exciting time ⁣in this field.Professor Stamatakis stated that the research could​ have​ a significant impact ⁣on healthcare ‍by translating findings into advice. ⁢He also mentioned the need for ⁤further research to establish causal links, but suggested​ that the timing of ⁣physical‌ activity could⁤ be crucial in managing obesity ⁢and Type 2 diabetes, as well as preventive healthcare in general. The study‍ was documented ‍in the journal by⁣ Angelo Sabag ‌et ​al.The title of the article is “Association of Moderate to Vigorous⁢ Physical Activity with Mortality, Cardiovascular Disease, and Microvascular Disease in Adults with Obesity”.⁤ The ⁤article was ‌published in Diabetes Care in 2024 with a DOI of ‍10.2337/dc23-2448.
