We may be riding an economic roller coaster, but one fact is certain: the weather is cold. And who wouldn't like to save a few bucks on heating bills this winter? When it comes to winterizing your home, the fundamentals still apply:

• Inspect the attic for proper insulation. Check.

• Inspect the furnace and replace the filter. Check.

• Replace batteries in smoke and carbon monoxide detectors. Check.

• Clean out the gutters. Check.

• Check for air leaks around windows or doors. Pause.

There's an opportunity to do more with winterizing windows and doors, because leaky windows or doors can be symptomatic of larger issues. Take a closer look and determine if proper caulking, more insulation (or weather stripping if it's a door) or a full replacement is in order. A properly installed and maintained window or door is key to proper performance to help seal out air and moisture. Consider energy-efficient replacement windows and doors.

Healthy home No matter where you live, the onset of winter brings the likelihood of spending more time inside. Many elements can contribute to the health and safety of a home-windows being one of them.

What's a homeowner to do? How can you maintain your own healthy home? For starters, try these concepts developed by design experts Amy Ellison Ostberg and Michelle Roberts - the 7 Design Principles for Healthy Homes:

1. Keep it dry
2. Keep it clean
3. Keep it ventilated
4. Keep it safe
5. Keep it free of contaminants
6. Keep it well-maintained
7. Keep it pest-free

Windows allow natural light and fresh air into the home and provide protection from the elements. Windows can also play a major role in the health of a home. Look for products that help minimize certain indoor airborne allergens. Such windows feature optional blinds, shades or decorative panels between panes of glass to help eliminate dust and dirt accumulation usually rampant on common window treatments.

Hunker down and help your immunity So this winter, don't let being inside get you down. Flu and cold germs can run rampant in cold weather. Stay warm and help maintain your health by exercising, getting fresh air, washing your hands frequently, drinking adequate amounts of water and allowing yourself plenty of rest. After all, a healthy home also includes occupants that feel their best.
