There is so much talk about the heart monitor watch, and heart training these days. It appears you cannot do an effective work out without being bleeped at by a heart monitor watch throughout the session. But what are all these zones about and what do they mean?

Well you first have your Aerobic Zone.

This is the next zone up from your natural resting heart rate. This is the zone that you will start off in. You will need to develop how you perform in this zone before you can move on to the next.

The Anaerobic Zone

In this zone you will not be burning fat so much as using glycogen which is stored in the muscles and is more commonly known as lactic acid.

The Red Line Zone

Many of us will never get our heartbeat to this zone. This zone is usually reserved for the extremely fit amongst us, the top athletes who enter this zone for short periods only, like when they run a race at competition level.

Some other things that can affect your heartbeat are:

Dehydration – this can increase your heart rate by up to 7%.

Heat and humidity can also increase your heartbeat and so can altitude by up to 20%.

Because you cannot see your heart it is very easy to concentrate on how your legs, arms or other parts of your body look. Working on getting your heart performing more effectively can have massive health benefits, and studies have shown that a well exercised heart goes a long way to beating heart disease and problems. So get to know and understand your zones.

Acne struggles can be frustrating, embarrassing and in some cases even depressing. While many people associate acne with teens, the truth is acne can strike both men and women at any age.

In an effort to combat this frustrating condition, there are new methods always being developed, such as the blue light acne therapy.

What is it?

Some people compare blue light therapy to other laser therapy methods. This narrow band of blue light has been used with some success in treating moderate to mild acne. The light is very high intensity and is reported to use no UV lasers or lights.

It is also reported to be pain free. The therapy uses the blue light to kill bacteria which is known to cause acne. One treatment of blue light acne therapy is not usually beneficial.

The patient suffering from acne problems will have to be treated multiple times, and with each treatment costing at least $40.00 the cost can rise quickly into the thousands of dollars. It has also not been proven to be effective in all cases, but merely positive results in some cases.

How Long Does it Take?

These acne therapy procedures are relatively fast and reported to be painless. The light source (blue light) is placed very near the patients face for around 30 minutes.

As soon as the procedure is over the person can resume regular daily activities. The procedure is done with the patient either lying down or sitting so that the patient is most comfortable.

Possible Risks

There are few risks associated with blue light acne therapy, although some cases have reported stinging and burning after treatments, along with some cases reporting swelling and even redness.

In rare cases, there have been reports of an allergic reaction to the solution used before the procedure for photosensitizing. Because this form of acne therapy is fairly new, no long-term side effects have been determined at this point.

While blue light acne therapy may produce positive results with some patients, it has not produced results with all patients. Repeat treatments are necessary, which makes this a costly option for curing acne, especially when there are no guarantees it will work.
