If you are cold and no fever....get yourself an Afghan or blanket and put on a warm shirt and get yourself warmed up. If your feet are cold, put on socks.
There are a lot of bugs going around. Drink a glass of Orange juice followed by a cup of warm tea, with or without honey. Be sure to get some vitamin D to boost your immune system, chicken soup, and a little sandwich or salad and fresh fruit, if possible.
If you are hungry, eat. If you are homeless, find a soup kitchen, get shelter and put on extra clothes until you get warmed. Actively seek a refuge from the cold.
Sometimes we get chills as our body begins to fight an illness. So buff up your ability to fight off bugs. Wash your hands befor you eat, and after using the restroom. Don’t eat anything you suspect is not healthy! Serve in that soup kitchen, make sure the food is good. And the kitchen is almost always the warmest room. At home, boil some water, add some steam......
