My dear MAM ., you get up easy in the morning? I think you feel cold outside and have nice and warm under the blanket and must be hard to get from warm bed! I remember when I was a child and my parents was farmer in the mountains and so our house had now heater at night and in the winter time we had icy window inside. It was hard but was funny anyway, Was a very old house and the cold come through the windows which were not so tight.
For shower we had a heater for warm water and so get quickly warm Body. At my flat I have in every room heater with warm water and so is inside never below then 20 degree.
Have a nice day and good luck, jup .. jupppppppppppppppppppppppp..
