Staying Mobile in Fall

Motion is Lotion: Protecting Your Joints as the Crisp Air Arrives

If your knees or hips ache a little more on a brisk October morning, it isn’t in your head. Drops in barometric pressure and cooler temperatures can cause the tissues in our joints to expand slightly and joint fluid to thicken, leading to morning stiffness.

While the instinct is to stay bundled up inside and avoid movement to “save” your joints, that approach is actually counterproductive. Joints do not have a direct blood supply. They receive their nutrients from synovial fluid, a thick liquid that lubricates the joint capsule. The only way to pump that nutrient-dense fluid into the cartilage and flush out inflammatory waste is through physical movement. In the medical world, this is known as the “motion is lotion” principle.

Strategies for staying mobile in Tuolumne County this fall: 

• Dress your joints in layers: Keep your knees and elbows warm before you head out. Wearing a base layer of thermals helps keep the synovial fluid warm and moving freely.
• Seek out flat, paved trails: Autumn leaves covering rocks and roots can turn a steep hike into a trip hazard, and uneven terrain forces knees into awkward angles. Swap rocky hikes for the flat, historic Westside Trail in Tuolumne, or stick to the paved, ADA-accessible lower sections of the Dragoon Gulch Trail in Sonora.
• Afternoon over morning: If morning stiffness is an issue, shift your outdoor walks to the afternoon when the foothill sun has warmed the air, and your joints are naturally more limber.
