While I normally do not address the topic of shoveling snow until January, considering recent weather events, I thought it might be valuable to present it sooner. Much has been written about the dangers of snow shoveling for your heart. However, while not fatal, low back pain is the most common injury sustained while shoveling snow. Heart attacks are also more common following wet and heavy snow.

Snow shoveling can place excessive stress on the structures of the spine. When overloaded and overstressed, these structures fail to support the spine properly. The lower back is at great risk of injury when bending forward, twisting, lifting a load, and lifting a load with a long lever. When all these factors are combined simultaneously, as in snow shoveling, the lower back is destined to fail. Low back pain from muscle strain or a herniated disc is very common following excessive snow shoveling.

Snow Shoveling as a Form of Exercise:

• GOOD - For the Young and Healthy – studies show that snow shoveling for 15 minutes is considered moderate physical activity and extreme and vigorous physical activity when performed more than 15 minutes even for young healthy college students.
• BAD – For the Older and Unfit – research clearly shows that there is a significant increase in heart attacks among snow shovelers. If you have any risk factors or medical condition and do not exercise regularly consult your physician.
• Cold Weather – makes this activity even more difficult and physically stressful. Cold air makes breathing more labored and difficult and cold temps create added strain on the body.

People at High Risk of Illness Due to Snow Shoveling:

• History of Heart Attack
• History of Heart Disease
• History of High Blood Pressure or High Cholesterol
• Smokers
• Inactive & Sedentary Lifestyle
• Overweight
• Elderly

10 TIPS FOR SAFE SNOW SHOVELING:

1. MEDICAL CLEARANCE: If you have any medical condition or risk factors consult your physician.
2. PAIN: Stop immediately if you experience any pain. Especially in the chest, left arm, jaw, face, neck, or lower back.
3. ERGONOMICS: Choose a snow shovel that is right for you:
   1. An ergonomic shovel with a curved handle allows you to keep your back straighter or arched when shoveling
   1. An ergonomic shovel with a shorter or adjustable handle length allows you to keep your back straighter and knees bent when shoveling. The right handle length allows you to arch your back 10 degrees with your knees slightly bent when the shovel is on the ground.
   1. A plastic shovel blade is lighter than a metal one and will be better for your spine.
   1. A smaller blade is better than a larger blade. It may take longer but will stress your back less.
4. PUSH: When possible, push the snow. Do not lift it. Lifting is much more stressful on the spine. You can find shovels that are ergonomically designed just for pushing snow.
5. WARM – UP: Be sure your muscles are warm before you start to shovel. Cold and tight muscles are more likely to strain than warm, relaxed muscles. Layer and consider compression shirts or tights can help prevent cold and tight muscles.
6. LEVERAGE: When you grip your shovel, spread your hands at least 12 inches apart. This will improve your leverage and reduce strain on your lower back.
7. TECHNIQUE: Shoveling technique is very important. The American Academy of Orthopaedic Surgeons recommends:
   • Squat with your legs apart, knees bent and back straight.
   • Lift with your legs. Do not bend at the waist.
   • Scoop small amounts of snow into the shovel and walk when you want to dump it.
   • Do not hold the filled shovel with outstretched arms.
   • If snow is deep, remove in piecemeal, a few inches at a time.
   • Rest and repeat as necessary.
   • Move your feet and do not twist your back as you shovel or dump. Never throw snow over your shoulder
8. CAUTION: Be cautious shoveling wet snow. One full shovel can weigh 25 pounds.
   • Shovel wet snow slowly in piecemeal.
9. PACE YOURSELF: Take frequent breaks and stretch your back in the opposite direction of shoveling. For example: 1. Lean backwards and extend your lower back. 2. Pinch your shoulder blades together.
10. TECHNOLOGY:
    • Snow Blower - Use a self-propelled snow blower. It will put much less stress on your lower back than shoveling snow if used correctly. For example, push the blower with your legs and keep your back straight or arched and knees bent.
    • Ergonomic Shovels:
    • 2 Handle Shovels: ErgieShovel or Snow Joe Shovelution
      • Push Shovels: Garant Yukon or Garant Sleigh Shovel
    • Snow Melting Alternatives:

There is little doubt that the workplace has been redefined since the pandemic as many employees continue to work from home. Sitting for many hours at a workstation that may not be optimal has also changed the way we define workplace health and safety. It may be more important than ever to pay close attention to designing an ergonomic workstation, changing position, and stretching regularly to prevent injury.

Since 1894 Labor Day has been designated as the national holiday that pays tribute to the contributions and achievements of American workers. Research supports the notion that healthier employees are happier and more productive. When employers encourage healthy behavior and safety at work, they benefit in many ways. For example, in addition to improving job satisfaction and productivity, healthy employees save money by using less sick time, worker’s compensation benefits and health benefits. For example, according to the Centers for Disease Control and Prevention, approximately 75 percent of employers” health care costs are related to chronic medical problems such as obesity, diabetes, high blood pressure, and high cholesterol. De-conditioned, overweight employees are more likely to suffer from these preventable conditions and are at greater risk for injury. Employers, please consider using this holiday as an opportunity to start a health promotion program at your workplace…have a health fair, offer healthy snacks, encourage walking, smoking cessation, exercising at lunch, and offer fitness club stipends.  

Lower back pain, one of the costliest illnesses to employers, is one example of a problem which can be prevented with a good health and safety program. It is widely accepted in the medical community that the best treatment for lower back pain (LBP) is prevention. Keeping fit, (flexible and strong), practicing good posture, and using proper body mechanics are essential in the prevention of LBP. At our clinic, significant time and effort is spent emphasizing the importance of these concepts to our patients, employees, and the businesses we work with through industrial medicine programs. A comprehensive approach can produce significant reductions in LBP injuries through an onsite safety program which promotes education, wellness, body mechanics, lifting techniques, postural and stretching exercises and ergonomics. 

Prevention of Lower Back Pain

1. Maintain Fitness Level

As little as 10 extra pounds puts great stress on your lower back. It also makes it more difficult to maintain good posture. Eat well, exercise regularly and don’t smoke. Smokers have a much higher incidence of LBP and failure from lower back surgery.

2. Practice Good Posture & Body Mechanics

Good posture is critical for a healthy back. When sitting, standing or walking maintain a slight arch in your lower back, keep shoulders back, and head over your shoulders. In sitting, use a towel roll or small pillow in the small of the back. Also, consider sitting on a physio ball, which promotes proper posture for part of the day.

 Perform postural exercises throughout the day. Most of the day we sit, stand, and reaching forward and bend our spine. These exercises are designed to stretch your back in the opposite direction of flexion. Please perform slowly, hold for 3-5 seconds and repeat 6 times each 6 times per day.

Chin Tuck: Tuck your chin back to bring your head over shoulders.

Shoulder Blade Pinch: Pinch your shoulder blades together.

Standing Extension: While standing, put your hands behind back and extend lower back 10-20 degrees.

Good Body Mechanics and ergonomics are also important in the prevention of LBP. When lifting, think twice. Think about the weight, shape and size of the object. Think about where the object is going and the surface resistance of the floor. Does it require two people to lift? Can I safely lift that high or bend that low?

When bending to lift an object think about safety:

Proper Lifting Technique:

• Spread Legs Apart Shoulder Width
• Bend at the Knees and Limit Forward Bending the Spine
• Arch Lower Back Slightly
• Get and Maintain a Firm Grip
• Contract and Hold Abdominal (stomach) Muscles
• Lift With Legs (not back)
• Do Not Pivot or Rotate Spine With Load (use feet and step turn)
• Lift Slowly and Carefully (don’t hurry)
• Take Time to Perform Back Extension Stretches After the Lift
• Remember, Pushing is Better Than Pulling a Heavy Load

Visit your doctor regularly and listen to your body.
