How to cure the flu/common cold and not get it at the first place

I am very sensitive to cold weather. Years of experience in many different places, hot and cold, and experience observing and talking with others, has led me to the conclusion that you can prevent common cold and flu almost completely if you stay warm. If you are wearing no winter clothes (insulation) and are dressed in a t-shirt and shorts/skirt, you will catch a cold/flu if exposed for about 60 minutes when the outside air temperature is 20C (this  is approximate; people who are very sensitive to cold will get sick at 22C, while the tough ones will get sick below 15C). You will also NEVER catch a cold with the same dress if the outside air temperature is 25C or above. Ambient air temperature and body insulation are the important factors for catching a cold/flu.

Note that for me, catching the cold is same as the flu; they have the same symptoms [runny nose, sore throat, headache, fever]. Diseases are defined by symptoms, not by what causes them. Causes after all are theories-and theories come and go. 

I don't believe that the flu virus or any viruses exist and the whole science of virology is a big scam, and must be buried just like we buried bloodletting and lobotomy.

Main observation: In warm countries ( >30C temperature) or in summer (>30C) you never catch the flu. I have flown from cold weather with a terrible flu to a warm country, and the flu was gone in 24 hours after arrival into the warm country. By warm I mean really warm, >30C temperature.

Staying warm is the surest way to avoid getting the flu. As the air temperature drops below 20C, you need more and more winter clothing (insulation) and heat the ambient air.

Even if you are bundled up in all your winter clothes, if you are breathing cold air, you will catch a cold. Inhalation and exhalation of cold air is like convection loss of heat-it takes away a lot of heat from your body by the sheer amount of air you inhale and exhale every minute. The solution is to at least moderately heat up the air around you. This is the reason when people go climbing high mountains they heat up their tents at night-because even though they have the best winter clothes on, it is not sufficient, and the air with is breathed needs to be warm as well.

Another solution is to cover up your head completely when sleeping in cold air, and leave only a very tiny hole for replenishing the oxygen/air. You inhale mostly the air you exhale, so it is somewhat suffocating, but you don't get the flu, because exhaled air is warm. The suffocating feeling is a tradeoff to getting the flu-I myself can't sleep like this because I need to breathe more oxygen and can't recycle so much CO2 in exhalation. But I know many who do this successfully. I believe the homeless folk in Toronto or New York also survive the winters using this technique.

A good way to get some heat if it is not possible to heat up the room is to drink hot beverages-hot tea, hot coffee, etc. In the very cold Argentine Patagonia people keep drinking hot mate every few hours, which keeps them warm. Ingesting a hot liquid gives you a lot of heat in calories, and is a very efficient and cheap way to stay warm if heating the surroundings is not possible. Drinking hot liquids helps in avoiding the flu at the first place; and if you do get the flu, it will help it cure faster.

A common way people will catch a cold, without realizing it, is from excessive exposure to cold water-e.g. by washing dishes, or by drinking ice cold water. This can happen in the summer or the winter-and avoiding contact with cold water will reduce your chances of catching a cold/flu.

If you keep moving outside even in heavy snow you don't get the flu. Exercise and movement prevents it-probably because body is warmed up and the cold air doesn't reach lungs, only in nose. If you stay still in snow you will get flu.

Flu is not contagious. If you are warm, it doesn't matter if everyone around you has the cold. This has huge ramifications for children, who sometimes are forced to miss school because of the bad conclusion that the flu is contagious. The recommendation to wash your hands, not come in contact with people who have flu etc. are useless.

If you are in a temperature below 20C and are not dressed to keep warm, you will catch a cold, even if you are in the summer. This happens to people all the time when the air conditioning (A/C) is too high. The solution there is to always carry some sweater or winter clothing in buildings which run the A/C too high. It is not contracted from other people having the flu-flu is an intrinsic process, due to exposure of respiratory lining and tract to cold air.

The symptoms and the suffering is considerably reduced if you remember to always stay warm even after contracting the flu/cold.

Lemons, gingers, etc. are remedies which are proposed as solutions for alleviating the symptoms of the flu. My experience is that none of these work. The best solution seems to be temperature control, firstly to prevent you from falling ill with the flu, and also to cure it fast.

Taking a pain killer like ibuprofen and sore throat reliever does help in reducing the severity of the symptoms.

Yearly flu shots are bad science, they do not work, from my own personal experience many years ago of getting them for 6 years in a row  and still coming down with the flu. You will get the flu even if you get a flu shot if you are exposed to cold weather. Here are details on why flu shots don't work. Avoid getting yearly flu shots.
