Seasoned travelers have a saying -- "Pack your bags, then take out half."

This refers to the fact that most of us bring much more than we need on our trips. Now, even more travelers are echoing that line, especially, since so many airline providers are charging passengers a fee for checking luggage. However, if you are one of those people who cannot decide which half to leave at home here are some recommendations to help you carry your baggage safely.

According to the U.S. Consumer Products Safety Commission, In 2007, more than 50,000 people were treated in hospital emergency rooms, doctors' offices, clinics and other medical settings for injuries related to luggage.

Packing light may prevent injuries such as:

• Strains, pulls and tears: Any of these can occur while carrying a heavy suitcase for an extended period of time.
• Lifting and holding a bag incorrectly or lifting luggage from baggage claim carousels, overhead or under-seat compartments. The chances of these injuries are even greater when a person has been sitting still for a long period of time (as when on a plane) or when the luggage is over-packed and especially heavy.

"Using proper lifting techniques can ensure that your trip isn't cut short by an injury," says William R. Marshall, M.D., an orthopaedic surgeon in Fort Walton Beach, Florida. "Even a relatively minor injury, such as a muscle pull, to the back, neck or shoulders can be quite painful in the short term and end up ruining your vacation."

Consider these following strategies to prevent injuries when lifting and carrying luggage:

Pack lightly. When possible, pack items in a few smaller bags instead of one large luggage piece. It is better -– and may prevent muscle sprains and strains -- to carry a lighter bag in each hand rather than one heavy bag in one hand or over one shoulder.

Bend at the knees. As with any heavy lifting, you should bend at the knees and lift luggage with your leg muscles -- not your back and waist -- and avoid twisting and rotating your spine. Stand alongside your suitcase, bend at your knees, then grasp the handle and straighten up. Also, try to carry luggage as close to your body as possible.

Be careful lifting. When placing luggage in an overhead compartment, first lift it onto the top of the seat. Then, with the hands situated on the left and right sides of the suitcase, lift it up. If your luggage has wheels, make sure the wheel-side is set in the compartment first. Once wheels are inside, put one hand atop the luggage and push it to the back of the compartment. To remove the luggage, reverse this process.

Check your backpack. If using a backpack, make sure it has two padded and adjustable shoulder straps. Choose one with several compartments to secure various-sized
