Sick from Winter Season?

What illnesses have you been experiencing  this winter season? I really hate winter especially the month of January and February. In winter season we usually get cold, cough, fever, or headache! It gives additional stress and troubles. Today I have got an headache, cough and cold, so I must take a medicine to get rid of it, see it's additional expense! Now My hubby seems has a flu, he is experiencing cough and cold, and it's obviously due to the winter season (climate changes). Here in southeast even it's winter time the degree has changed everyday, if it is cold or coldest today it will drop down to warm; warm to cold, cold to warm, warm to coldest, it's just crazy (lol), so I would say it is very difficult to adjust in a winter time. And due to this climate (winter degree) changes it could cause  people to easily get sick. I am one of those people (lol). Me, as an Asian it's really difficult for me to adjust the weather in United States especially in Winter Season, everywhere is COLD (ha ha). Well, I am pretty sure even the Americans who were originally born here have not even been adjusted from the weather (lol)!
