It’s time for cold and flu season, when it seems everyone you know is suddenly sneezing, sniffling or worse, when a chill is in the air. It’s almost as if the cold and flu germs come with the first blast of winter. People get more colds, flu and Covid-19 when it’s cold outside.

A new study may have found the biological reason why we get more respiratory illnesses in winter. The immune response in the nose is damaged by the cold air. The rhinologist said that this is the first time that they have an explanation for one factor of our innate immune response that appears to be limited by colder temperatures.

There is a professor of otolaryngology and head and neck surgery at the school. She was not involved in the new study.

According to a study published Tuesday in The Journal of Allergy and Clinical Immunology, reducing the temperature inside the nose by as little as 9 degrees Fahrenheit (5 degrees Celsius) kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils.

Do you think the holiday food coma is true?

Many people do. A mainstay on the dinner table at this time of year, turkey contains tryptophan, which is widely believed to be responsible for the uncontrollable yawns and sudden snoozes common after huge family feasts.

To get the amount of tryptophan required to cause a food coma, he said, we’d have to eat about 8. One pound of turkey meat is recommended by the US Department of Agriculture.

Tryptophan from turkey is unlikely to enter the brain and make us sleepy, so you can’t blame the gobbler on your table alone. It’s important to remember all the delicious side dishes surrounding the center piece of turkey, such as sweet potato pie, casseroles and yummy desserts, because overeating in general is a major culprit for the fatigue one feels after eating. These tasty dishes have a high amount of sugars.

Environmentalists say that plant-based milk is better for the planet than dairy-based milk. The world record for milk production by a Holstein is held by Selz-Pralle Aftershock 3918, a cow in Wisconsin.

According to a widely quoted 2018 meta-analysis of studies on the issue, worldwide demands on natural resources to feed and water dairy cows remain enormous.

According to an analysis of the 2018 study by the Global Change Data Lab and the University of Oxford in the United Kingdom, the dairy industry uses 10 times as much land as soy, oat, almond or rice milk production.

The analysis found that dairy creates three times as many greenhouse gas emissions. Methane, a greenhouse gas 80 times more powerful than carbon dioxide in warming the planet in the span of 20 years, is generated by gas and solid waste from ruminating animals.

Milk is a critical source of nutrition in some parts of the world. That could make the question of which milk is best for the planet more complicated for you and your children.

Americans are failing in their quest for adequate slumber, leading to deficits that can impact health, according to a new study. Americans ages 20 and older were collected by the National Health and Nutrition Examination Survey.

According to the study, almost 30% of respondents had trouble falling or staying asleep and 27% were very sleepy during the day.

One in 10 adults had a sleep debt of two hours or more, and over 30% of adults had an hour of sleep debt.

According to the US Centers of Disease Control and Prevention, adults over the age of 18 need at least 7 hours of sleep a night to be healthy. Sleep debt, along with irregular sleep duration, has been linked to an increased risk of heart disease, dementia, and mood disorders. A large and representative sample was examined in the study.

A quarter of the population complained of being sleepy during the day.
