Dr. Whitaker's Guide to Healthy Living

Improve your sleep
Many of us neglect a very important health process: sleep. Americans spend 20 percent less time sleeping than we did a century ago, and yet our lives have only gotten more hectic. Lack of sleep affects many body processes, from mental clarity and mood to physical energy and immune function.

To enhance your ability to sleep, develop a bedtime routine. Go to bed and get up at the same time every day, and avoid alcohol, caffeine, and strenuous exercise several hours before bed. Keep your room quiet and dark and the temperature even.

Kill bacteria and viruses all day long
The air you breathe is doing more than keeping you alive — it's giving a free ride to bacteria, viruses, toxic chemicals, dust and molds. The Sun Pure Air Purifier gets rid of these pollutants so your family breathes the purest, healthiest air possible. UV light kills the bacteria and viruses that make you ill. A hospital-grade HEPA filter removes 95.5 percent of allergens down to .3 microns (a human hair is more than three times wider!), and an activated carbon filter eliminates odors and gases. Super quiet and efficient, it also has an unconditional two-year warranty.

Remove harmful substances found in your water system
When you pour yourself a glass of water you may be ingesting more harmful contaminants than you'd care to know about. That's why you should filter all the water you drink. In addition to having a filter at the kitchen sink, you may also want an easy-to-use, portable filter. The AQUASPACE Water Carafe, using NASA filtration technology, removes 45 volatile organic compounds without taking out the essential minerals your body needs. The filter works for an entire year, filtering up to 500 gallons of water and weighs just over a pound, making it easy to take and use anywhere.
