Wrinkle-free sheets may seem like a revolutionary convenience, but they may actually be preventing you from getting a good night's rest. Poly-blend cotton sheets that are "wrinkle-free" often have finishes on the fabric that release formaldehyde. The chemical can be an irritant that bothers your throat and eyes. Look for organic, 100 percent cotton sheets instead. If you want them to look pristine without the hassle of chemicals or using an iron, just take them out of the dryer when they are still hot. This will prevent wrinkles from setting.

If you have a backyard pool that uses chlorine to keep it clean, you can reuse the water when it's time to drain the pool to get it ready for the fall and winter months. The first step: Stop using chemicals altogether and wait half a week. This will reduce the pH level of the pool water to a safe and acceptable level. You can rent an electric pump from your pool supply store and attach a hose to it; as it siphons the water, you can use it to water the lawn, plants and other landscaping. Remember, discharging chlorinated water into the drainage of your own property is illegal in most communities, so these simple actions can make a big difference.  

When spending time in an airport, look for beverages in recyclable containers like aluminum cans and plastic bottles when you're thirsty. If you can't find recycling bins, bring your drink with you on the plane. Most airlines now have recycling programs that collect old newspapers, magazines, cans and bottles. They sort and separate in-flight and divert trash away from landfills.
