Flu, recovering from a beginning flu

"Having gotten cold and AVOIDING A FLU
To catching a cold it helps to keep thoroughly warm in a warm place indoors and to eat some vitamins. I do not know this so well, I guess that all Finns have likewise their own advices about curing a cold.
When you have catched a cold, it is important that you do not get any exposure to cold anymore. You have to stay in a warm place, wear loose dry woolen socks, warm clothes and a blanket and drink something hot and eat an orange, and if you have been very cold, then eat something that makes you strong, like a meatpie or a warm meal, if you can but at least some bites. The orange or juice should not be cold at all and not the environment either at all.
If you need to ventilate the room, put the cold one to bed under a thick blanket and others ventilate a lot quickly and then let the air get warm before one can get out from the shelter of the blanket. And if one has been very cold or still is, don't ventilate the same room, but shut the door and ventilate other rooms and let the air get warm again before you open the door.
Others serve. If you are only a little cold, you may move like feels good for you. The skin should not be cool anywhere, neither the body or it's parts, but if it is, wear warm woolen clothes as it's shelter, drink hot and eat warm food and if one lies in bed wear a thick blanket and a daytime wide decoration blanket over to prevent cold air from breezing from the gaps in the sides of the blanket. You should not ventilate if you do not need to, and not spend any longer time in cool even if you are only a little bit cold.
The one who has catched a cold should be informed (if you know these things for sure) about the temperature of the environment and about it's changes and about the observations of others about one's skin and body temperatues at different places (legs, feet, hands, arms, forehead) of one's body, but one should not disturb the one who has catched a cold by these things more than once or twice, except always inform about the temperature changes of the environment.
The most important thing is to not to get any cold anymore, because such would bring a worse illness. Listen to what brings you wellbeing and hope when you have catched a cold, and cultivate those options.
The clothes and blankets ahould be dry, loose, warm and quite clean."

"In curing a flu, at least slimy cough, there are the same advices to be diligently followed as in avoiding a flu: warm clothes, warmer than how one caught a cold, don't spend time in cold, espcially not without walking or the like, wrists, feet and near the throat keep protected by warm clothes (long-sleeved shirt, knit or the like, outdoors loose wind-proof coat, warm quite long socks and warm shoes) so that there is no need for coughing but instead one has warm kind of round feeling like in a sofa."
