Here s how coffee temporarily counteracts effect of sleep loss on cognitive function ANI | Updated: Jan 22, 2021 08:22 IST
Washington [US], January 22 (ANI): A new study exploring the impact of repeated sleep loss during a simulated working week has found that consuming caffeinated coffee during the day helps to minimise reductions in attention and cognitive function, compared to decaffeinated coffee.
While this effect occurred in the first three-to-four days of restricted sleep, by the fifth and final day, no difference was seen between caffeinated and decaffeinated coffee drinkers. This, therefore, suggests that the beneficial effects of coffee for people with restricted sleep are temporary.
Study suggests being fat linked with worse heart health even in people who exercise ANI | Updated: Jan 22, 2021 08:31 IST
Sophia Antipolis [France], December 22 (ANI): Physical activity does not undo the negative effects of excess body weight on heart health, suggest the findings of a large study.
The study was published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). One cannot be fat but healthy , said study author Dr Alejandro Lucia of the European University, Madrid, Spain. This was the first nationwide analysis to show that being regularly active is not likely to eliminate the detrimental health effects of excess body fat. Our findings refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight and obesity.
New insights into link between sunlight exposure and kidney damage ANI | Updated: Jan 22, 2021 08:51 IST
Washington [US], January 22 (ANI): A new collaborative study reveals unexpected insights into how skin exposure to ultraviolet (UV) light can worsen clinical symptoms in autoimmune diseases such as lupus.
The study from researchers at the Geisel School of Medicine at Dartmouth and the University of Washington (UW) was published in the Proceedings of the National Academy of Sciences (PNAS),
Lupus, an autoimmune disease that can cause inflammation of the joints, skin, kidneys, blood cells, brain, heart and lungs, is caused when the immune system attacks its own tissue.
Scientists reveal mechanism that causes irritable bowel syndrome ANI | Updated: Jan 19, 2021 10:49 IST
Washington [US], January 19 (ANI): Researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances.
The study, carried out in mice and humans, was published in Nature.
Up to 20 per cent of the world s population suffers from irritable bowel syndrome (IBS), which causes stomach pain or severe discomfort after eating. This affects their quality of life. Gluten-free and other diets can provide some relief, but why this works is a mystery, since the patients are not allergic to the foods in question, nor do they have known conditions such as coeliac disease.
Study links one alcoholic drink in a day to increased risk of atrial fibrillation ANI | Updated: Jan 19, 2021 11:36 IST
Washington [US], January 19 (ANI): A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm.
The study, published in the European Heart Journal found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16% increased risk of atrial fibrillation over an average (median) follow-up time of nearly 14 years.
This means that while four teetotallers in 100 might develop atrial fibrillation over the period of the study, five per 100 might develop the condition if they consumed alcohol starting with slightly more than an alcoholic drink a week and more than 75% of them consumed up to one drink a day [2]. The researchers categorised one alcoholic dri
