Drafty windows and poor insulation are common causes for cold bedrooms.
A cold bedroom is an uncomfortable bedroom, though detecting the source of the problem can be difficult. Stop-gap measures such as space heaters, electric blankets and hot water bottles can present fire or scalding hazards and are often cumbersome or ineffective. To keep your bedroom consistently warm, familiarize yourself with the common, underlying reasons for chilliness.
Poor Exposure
Sunlight can often make the difference between a cold bedroom and a warm bedroom. Lack of sunlight during the day can exacerbate other negative conditions, such as dampness, that can lower the temperature in a room at night. Increasing exposure to sunlight is also one of the most cost effective and environmentally friendly ways of heating a room. If you have a choice of rooms, favor bedrooms that have southern exposure to increase the amount of direct sunlight you receive during the day. Prune braches or ivy that may be blocking sunlight from entering your room, and keep windows clean. Lastly, make sure to keep your curtains open during the day.

Draftiness can also be prevented in part by planting trees around your home. Mature trees block wind, which can dramatically reduce draftiness in your home.
Dampness
Dampness in the bedroom not only contributes to coldness, but can also cause other problems such as rot and mildew. If
