A popular rule states that each person should drink at least eight glassed of water a day to stay healthy and keep a healthy weight. Most people find it hard to achieve, though. A new study finds why it is so. The researchers identified a swallowing mechanism that doesn’t allow us to drink water when we are not thirsty.
For the study, a number of participants were asked to drink a considerable amount of water right after exercising (they were thirsty), and later in the day, when they were not thirsty. In both cases, the researchers asked people how difficult it was for them to swallow liquid.
Study co-author Michael Farrell from the Biomedicine Discovery Institute at Monash University, says: “Here, for the first time, we found effort-full after drinking excess water which meant they were having to overcome some sort of resistance. This was compatible with our notion that the swallowing reflex becomes inhibited once enough water has been drunk.”

Previous studies, published in The Lancet, connected the design of cities and growing epidemics of injuries, such diseases as heart disease, diabetes and cancer. In part three of the series of studies, researchers explain how to implement timely research to build healthier cities, planning and policy to improve the health of people living in cities.
Scientists predict that by 2050, the large cities in the United States of America, China, and India will increase their populations by 33%, 38% and 96%. And these increasing will lead to declines in physical activity, increases in air pollution and higher rates of road death and serious injury.
James F. Sallis, PhD, UC San Diego School of Medicine Distinguished Professor of Family Medicine and Public Health and first author of the paper, said: “Shifting from city infrastructure that encourages the use of automobiles to a design providing safe and easy walking, cycling and public transportation options would reduce traffic injuries, air pollution and physical inactivity.”

Have you ever thought that your health and wellbeing depends on your… thermostat (or on the room temperature it defines, to be more precise)? Scientists prove that it is healthier to maintain cooler temperatures in our houses. Here are 5 ways how room temperature may affect your health backed by numerous studies:
- Sleeping in cooler temperatures may help you lose weight.
- Lower temperatures can reduce respiratory complications.
- Prolonged exposure to high temperature affects organ function.
- Cooler temperatures help sleep well.
- Too high temperatures can stress the heart and lead to heart attack.
