Is it OK to Reboil Water?

Have you ever wondered if it’s okay to reboil water and drink it like many of us do with our tea kettles?

Reboiling water refers to the practice of boiling it, allow it to cool below the boiling point, and then boiling it again. Have you ever wondered what happens to water chemistry when you reboil water? Is it still safe to drink?

If you have perfectly pure distilled deionized water, nothing will happen if you reboil it. However, most of us use ordinary tap or well water, which contains dissolved gases and minerals. The chemistry of the water changes when you boil it because boiling drives off the volatile compounds and dissolved gases. There are many cases in which this is desirable. However, if you boil the water too long or reboil it, you risk concentrating certain undesirable chemicals that may be in your water. Examples of chemicals that become more concentrated include nitrates, arsenic, and fluoride.

There is a concern that reboiled water may lead a person to develop cancer. This risk is not unfounded, but it is small. While the boiled water is fine, increasing the concentration of toxic substances may put you at risk for certain illnesses, including cancer. For example, excessive intake of nitrates has been linked to methemoglobinemia (elevated level of a certain type of hemoglobin in red blood cells, which can cause tissue hypoxia, or shortage of oxygen, which can lead to serious health conditions) and certain types of cancer. Arsenic exposure may produce symptoms of arsenic toxicity, and has been associated with some forms of cancer. Even “healthy” minerals may become concentrated to dangerous levels. For example, excessive intake of calcium salt, commonly found in drinking water and mineral water, can lead to kidney stones, hardening of the arteries, arthritis, and gallstones.

The bottom line is that generally boiling water, allowing it to cool and then reboiling it does not present much of a health risk. So, if you keep water in a tea kettle, add water when the level gets low, and you aren’t likely to endanger your health. It’s best if you don’t let water boil completely down, which concentrates minerals and contaminants (not to mention possibly ruining your tea kettle). If you reboil water, it’s better to do it once or at most twice, rather than make it your standard practice. Pregnant women and persons at risk for certain illnesses may wish to avoid reboiling water rather than risk concentrating hazardous chemicals in the water.

Tea anyone?

Top 10 Reasons to Start Walking, By Wendy Bumgardner | Reviewed by Richard N. Fogoros, MD

Why should you start walking? Walking for 30 to 60 minutes each day is one of the best things you can do for your body, mind, and spirit. Here are great reasons to lace up your sneakers and get started.

Walkers Live Longer

The Honolulu Heart Study of 8,000 men found that walking just two miles a day cut the risk of death almost in half. The walkers’ risk of death was especially lower from cancer. Other studies have had similar findings – if you keep walking, you improve your chances of a longer and healthier life.

Walking Helps Prevent Weight Gain

If you add just 2,000 more steps a day to your regular activities, you may never gain another pound. So says research by Dr. James O. Hill of the Center for Human Nutrition at the University of Colorado Health Sciences Center. To lose weight, add in more steps.

You Can Walk off Weight

Exercise such as walking is an important part of any weight loss program. You must still watch how much you eat in order to lose weight. But walking helps you build healthy lean muscle, lose inches of fat, and pump up your metabolism. Of long-term successful weight losers, almost all maintain a program of walking or other exercises.

Walking Reduces Risk of Cancer

Study after study has shown that walking and exercise reduce your risk of breast cancer and colon cancer. Walking is also good for those undergoing cancer treatment, improving their chances of recovery and survival.

Walking Reduces Risk of Heart Disease and Stroke

Heart disease and stroke are among the top killers of both men and women. You can cut your risk of both in half by walking for 30-60 minutes a day. Get your blood moving.

Walking Reduces Diabetes Risk

Get out and walk for 30 minutes a day as your minimum daily requirement for health and to prevent Type 2 diabetes. A study by the Graduate School of Public Health, University of Pittsburgh, discovered that walking for 30 minutes a day cut diabetes risks for overweight as well as non-overweight men and women. Walking also helps maintain blood sugar balance for those with diabetes.


Walking Boosts Your Brain Power

A study of people over 60 funded by the National Council on Aging, published in the July 29, 1999 issue of Nature, found that walking 45 minutes a day at 16-minute mile pace increased the thinking skills of those over 60. The participants started at 15 minutes of walking and built up their time and speed. The result was that the same people were mentally sharper after taking up this walking program.

Walking Improves Mood and Relieves Stress

Walking and other exercise leads to the release of the body’s natural happy drugs – endorphins. Most people notice an improvement in mood. A November 9, 1999 study published in the Annals of Behavioral Medicine showed that university students who walked and did other easy to moderate exercise regularly had lower stress levels than couch potatoes or those who exercised strenuously.

Walking Can Prevent Erectile Dysfunction

What better reason for men to take a brisk two-mile walk each day – a reduced risk of impotence from mid-life onward.

It’s Easy to Get Started


All you need is a pair of comfortable shoes and to get yourself out the door or onto the treadmill. You can reap the benefits of walking from doing several shorter walks or one longer walk during the day.

So, get out there and start moving. Even a short walk is better than none. It’s easy and it’s really good for you!
