People tend to catch more colds in the winter. There are a couple of reasons why.

People gather inside more during the winter. Being closer together makes it easier to catch colds from others. Viruses that cause colds and flu survive better in drier air.

Scientists didn’t know if cold weather helped people get sick. But on December 6, 2022, scientists published new research.

They?explained?that the immune system attacks viruses in the nose. The immune system is?the cells and their responses that help the body fight off infection.?And, they found that this attack works better when it’s warm out.（藍(lán)思值710L）

Cold and flu season happens in the winter. There are multiple reasons why people tend to get sick in the winter. People gather inside more, and being closer together makes it easier to catch colds from others. Viruses survive better in low-humidity indoor air. Humidity is a?measure of the amount of water vapor in the atmosphere, and air with a lot of water vapor in it is known as humid.

Scientists didn’t know if temperature affected how people got sick. But on December 6, 2022, scientists published new research. They explained a previously?unknown?way that the immune system attacks viral intruders inside the nose. The immune system is?the cells and their responses that help the body fight off infection.

The scientists also found that the new immune response works better when it's warm out. （藍(lán)思值950L）

When chilly weather comes around, so do common respiratory infections. These are a type of illness that affect organs used for breathing, such as the nose, throat and lungs.

Viruses survive better in low-humidity indoor air. Humidity is a?measure of the amount of water vapor in the atmosphere, and air with a lot of water vapor in it is known as humid.

Scientists were less certain about whether lower temperatures actually impair human immunity. This is the?ability of a living thing to resist a particular infection by producing and releasing special protective cells.

On December 6, 2022, scientists published research that details a previously unknown way that the immune system attacks viral intruders inside the nose. And they found that it works better when it's warm.（藍(lán)思值1130L）

Chilly weather and common respiratory infections often go hand in hand. A respiratory illness is a type of illness that affects organs used for breathing, such as the nose, throat and lungs.

There are multiple reasons why people tend to get sick in the winter. People gather inside more during the winter, and being closer together makes it easier to catch colds from others. Viruses survive better in low-humidity indoor air. Humidity is a?measure of the amount of water vapor in the atmosphere, so air with a lot of water vapor in it is known as humid.?But there has been less certainty about whether lower temperatures actually impair human immunity, which is the?ability of a living thing to resist a particular infection by producing and releasing special protective cells.

Now, scientists published research on December 6, 2022, that details a previously unknown way that the immune system attacks viral intruders inside the nose. And they found that it works better when it's warm.（藍(lán)思值1190L）
