Why do colds and flus happen more in the cold weather if the cold temperature does not actually cause colds or flu infections?
The process is not fully understood, but some of the more current thoughts are that the flu prefers and thrives better in the humidity of colder weather (drier absolute humidity) compared to humidity in other seasons. It is thought that it might be only the humidity level differences that link viral flu and cold infections to the fall and winter seasons, but, as has often been cited, perhaps there is also a component of the closer proximity of people to each other indoors in the cold weather which allows for easier direct transmission of the viruses. Scientific studies have ruled out a role of weather temperature differences. It is proven that you don't get colds from being cold.
Other reasons are sometimes given, for example, one thought is that it is the lowered amount of available sunlight in these seasons and shorter length of time periods that people are outside in the sun that result in lower Vitamin D (the "sunshine vitamin") levels. Deficiency of Vitamin D can impact the immune system negatively, but there is not consensus among the medical community on how much impact this actually may or may not have on infection rates.
Another factor that gets discussed is that there may be an effect from lowered amounts of sunlight, especially ultraviolet sunlight, available in those seasons which helps to de-activate the viruses.
You are correct that it is not the cold temperature that gives us colds, but rather the microorganisms that move from person to person during the "cold and flu season" that make us sick with the flu or a common cold.

Did red dawn really happen?
Yes. It's actually a documentary.
How many labors happen in the Disney film Hercules?
There were actually 11 presented in the film.
Why do most floods happen in south America and Mexico?
Not a lot; mainly floods occur when it is raining harshly outside or the temperature is strange and changing from time to time. That's when it floods, because Mexico is usually tropical and nice weather, but sometimes it does flood... - Ashley Quimby
Does Sirius actually punch Lucius in OOTP Harry Potter Movie?
Yes but this does not happen in the book
Does the desert get a lot of tornadoes?
Tornadoes do occur in deserts but they are rare as weather conditions conducive to tornado formation do not happen often in deserts.
What will happen if there was no water and what will be the temperature?
the weather will hot and the temperture will incries
What happen to the pressure in an automobile tire in cold weather?
Pressure drops when the temperature drops.
At what temperature does it have to be for pipes to freeze, and how cold does it have to be for this to happen?
Pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius). This can happen when the weather is consistently below freezing for an extended period of time.
Do thunderstorms happen in cold temperature or warm temperature?
Thunderstorms are most likely to form during warm weather. In simple terms, the heat is their source of energy.
Can a scientist make weather happen?
No, scientists cannot make weather happen. Weather is a complex system influenced by various factors such as temperature, pressure, and moisture in the atmosphere, among others. Scientists can study and predict weather patterns based on these factors, but they cannot control or create weather events.
What causes weather to happen on Earth?
Weather is caused by the atmosphere responding to uneven heating of the Earth by the sun. The uneven heating results in temperature differences. These are what are known as cold fronts, warm fronts and other phenomena.
What statement represent the difference between weather and climate?
Weather refers to short-term atmospheric conditions in a specific place at a specific time, like 'today's temperature and precipitation.' Climate, on the other hand, describes long-term patterns of temperature, precipitation, and other atmospheric conditions in a region over a much larger timescale, like 'average temperature and precipitation over a year.'
In which layer of the atmosphere do weather changes happen?
Weather changes primarily occur in the troposphere, which is the lowest layer of the Earth's atmosphere, extending up to about 10-15 kilometers in altitude. This layer contains most of the Earth's weather systems and is where temperature decreases with altitude.
How cold is going to be today?
It depends on where you happen to be in the world. Local weather-forecast programmes on the TV or radio is the best source on what to expected regarding the likely temperature.
What temperature does dogs live in?
They tend to prefer cool weather just like us. But if you happen to live in a tropical island, like me, always have water handy.
Why is thermometer important for weather prediction?
Thermometers measure temperature. To make their forecasts, metereologists need to observe it as well as other factors such as atmospheric pressure, wind speed, wind direction, humidity and precipitation (rain).
What would happen without thermometers?
Without thermometers, it would be difficult to accurately measure temperature, making it challenging to monitor changes in weather, body temperature, or cooking temperatures. This could lead to issues such as undercooked food, inaccurate health assessments, and limited ability to predict weather patterns accurately.
