Yard Work and Gardening is Physical Activity

by Normand Richard, Certified Exercise Physiologist

Spring has finally sprung, which for most of us means it’s time to get outside and get those gardens in tip top shape! If you find it hard to get motivated you’ll be happy to know that things like digging, raking, hauling and pruning all support you leading a healthy active lifestyle.
There is sometimes a misconception that you must be in a fitness centre, wearing athletic clothing and dripping with sweat to be physically active. Truth is, getting outside in the fresh air and doing some yard work or doing chores around the house provides a variety of health benefits and you don’t need special clothes.
Here are some pointers to help get the most out of your physical activity while tending to your yard.
  • Yard work:
    • Consider more frequent, but less heavy wheelbarrow trips
    • If you have difficulty raking the entire lawn at once, do half earlier in the day and the other later in the day
    • Use a broom to clean your driveway instead of the garden hose. You will a) work the muscles in your upper body, and b) minimize water wasting
  • Gardening:
    • Avoid staying in one position (e.g. kneeling) for an extended period of time
    • When weeding your garden, alternate between your right and left hands to work both sides of your body
    • When lifting heavy soil bags, get your body as close as possible to the bag and ensure good lifting posture
Yard work and gardening can provide you with a strong sense of accomplishment. If you don’t have a garden, offer to help a neighbour or join a community garden. Don’t forget to put on your sunhat, kick back, relax, and admire the fruits (and vegetable!) of your labour. Visit us on Facebook and tell us your gardening stories. Let’s get outside and get active.

Noise-Induced Hearing Loss

Hearing plays an essential role in communication, speech and language development, and learning. Even a small amount of hearing loss can have profound, negative effects on speech, language comprehension, communication, classroom learning, and social development. Studies indicate that without proper intervention, children with mild to moderate hearing loss, on average, do not perform as well in school as children with no hearing loss. This gap in academic achievement widens as students progress through school.1,2
An estimated 12.5% of children and adolescents aged 6–19 years (approximately 5.2 million) and 17% of adults aged 20–69 years (approximately 26 million) have suffered permanent damage to their hearing from excessive exposure to noise.3,4
Hearing loss can result from damage to structures and/or nerve fibers in the inner ear that respond to sound. This type of hearing loss, termed “noise-induced hearing loss,” is usually caused by exposure to excessively loud sounds and cannot be medically or surgically corrected. Noise-induced hearing loss can result from a one-time exposure to a very loud sound, blast, or impulse, or from listening to loud sounds over an extended period.

Preventing Noise-Induced Hearing Loss

Hearing loss caused by exposure to loud sound is preventable.5 To reduce their risk of noise-induced hearing loss, adults and children can do the following:
  • Understand that noise-induced hearing loss can lead to communication difficulties, learning difficulties, pain or ringing in the ears (tinnitus), distorted or muffled hearing, and an inability to hear some environmental sounds and warning signals
  • Identify sources of loud sounds (such as gas-powered lawnmowers, snowmobiles, power tools, gunfire, or music) that can contribute to hearing loss and try to reduce exposure
  • Adopt behaviors to protect their hearing:
    • Avoid or limit exposure to excessively loud sounds
    • Turn down the volume of music systems
    • Move away from the source of loud sounds when possible
    • Use hearing protection devices when it is not feasible to avoid exposure to loud sounds or reduce them to a safe level5
  • Seek hearing evaluation by a licensed audiologist or other qualified professional, especially if there is concern about potential hearing loss
