What are the side effects of climbing stairs?

Climbing stairs is a common daily activity for many people. While using the stairs has many benefits such as improved cardiovascular health, strengthened muscles, and increased calorie burn, overdoing it can also lead to some side effects. In this article, we will examine some of the potential side effects of frequently climbing stairs and provide tips on how to avoid them.

Muscle Soreness

One of the most common side effects of frequently using stairs is delayed onset muscle soreness (DOMS). This type of soreness is felt 24-48 hours after the climbing activity and affects the major muscle groups of the legs like the quadriceps, hamstrings, and calves. The soreness is attributed to microscopic tears in the muscle fibers caused by the eccentric contraction of muscles when descending stairs.

Some tips to prevent and treat sore muscles from climbing stairs include:

  • Warming up with light aerobic activity and stretching prior to climbing
  • Gradually increasing duration and intensity of stair climbing over time
  • Taking rest days between intense stair climbing workouts
  • Ice or heat therapy on sore muscles
  • Light exercise to increase blood flow to the muscles
  • Massage

Joint Pain

Climbing up and down stairs requires repetitive motions that can put strain on the joints, especially in the knees and ankles. This can cause inflammatory pain in the joints for some individuals. Contributing factors include:

  • Overuse from excessive stair climbing
  • Poor stair climbing form such as heavy foot strikes
  • Underlying joint conditions like osteoarthritis
  • Weak muscles surrounding the knees and ankles
  • Tight or inflexible leg muscles

Ways to prevent joint pain from climbing stairs:

  • Improve stair climbing form – land lightly on the ball of the foot when going upstairs and use controlled motions going downstairs
  • Build leg muscle strength through exercises like squats
  • Stretch leg muscles regularly
  • Use joint supplements like glucosamine and chondroitin
  • Take breaks from stair climbing to allow joints to rest

If joint pain persists, see a doctor to identify any underlying issues.

Ligament Sprains

The ankles and knees are vulnerable to ligament sprains when climbing stairs, especially when done too quickly or intensely. Ligaments are bands of tissue that connect bones together and sprains occur when they are suddenly stretched beyond their limits.

Common ligament sprains from stair climbing include:

  • Ankle sprains – Usually involve the anterior talofibular ligament on the outside of the ankle in an inversion type motion
  • Knee sprains – Most often the medial collateral ligament (MCL) or anterior cruciate ligament (ACL)

Risk factors for sprains:

  • Descending stairs too quickly
  • Misstepping on a step
  • Poor proprioception or body awareness
  • Fatigue
  • Poor strength in ankle or knee muscles
  • History of previous sprains

Prevention tips:

  • Go slowly and use handrails when descending stairs
  • Maintain optimal body weight to avoid excess impact on joints
  • Wear supportive and slip-resistant footwear
  • Strengthen muscles with exercises like calf raises, squats, leg extensions
  • Practice balance training

Low Back Pain

Using stairs excessively can also lead to pain and tightness in the low back muscles. Contributing factors include:

  • Repeated flexion of the spine when climbing stairs
  • Weak core muscles unable to properly support the spine
  • Poor posture when climbing stairs such as slouching
  • Heavy loads being carried while using stairs
  • Pre-existing back conditions like disc herniations

Strategies for preventing back pain from stairs:

  • Maintain upright neutral spine posture when climbing
  • Avoid twisting motions especially when carrying loads
  • Lift loads properly by keeping them close to the body
  • Build core strength with exercises like planks
  • Take breaks from climbing to give back muscles a rest
  • Manage weight to reduce load on the spine

Increased Fall Risk

Frequently using stairs comes with an increased risk of potential falls, especially in older adults or others with mobility issues. Risk factors include:

  • Impaired balance
  • Reduced strength in the lower body
  • Neurological conditions affecting gait and coordination
  • Use of medications that cause dizziness or drowsiness
  • Poor vision or lighting on the stairs
  • Wearing slippery footwear on the stairs

Fall prevention tips:

  • Install handrails for support when using stairs
  • Improve lighting over stairs and use high-visibility tape on step edges
  • Remove trip hazards like loose carpeting or clutter on stairs
  • Wear slip-resistant and well-fitting shoes
  • Go slow on stairs and avoid carrying heavy objects
  • Ask someone to assist if needed
  • Do balance exercises like tandem stance and single leg stands

Increased Risk of Overuse Injuries

Excessive stair climbing places repetitive stress on the bones, muscles, ligaments, and tendons primarily in the lower body. Over time this can increase the risk of overuse injuries if the body is not given sufficient time to recover and adapt. Examples of overuse injuries related to stair climbing include:

  • Stress fractures in the leg and foot bones
  • Shin splints or medial tibial stress syndrome
  • Achilles tendinitis
  • Plantar fasciitis
  • Runner’s knee or patellofemoral pain syndrome
  • Iliotibial band syndrome

Injury prevention recommendations:

  • Increase training volume gradually over time
  • Take 1-2 rest days per week from stair climbing
  • Wear shock-absorbing shoes
  • Listen to body for signs of overuse like pain during or after climbing
  • Include cross-training like cycling or swimming to give muscles a break
  • Manage load if carrying objects upstairs

Aggravation of Pre-Existing Injuries

Individuals recovering from lower body injuries or with chronic conditions affecting their bones, joints, or connective tissues should use caution when climbing stairs often. Too much stair climbing too soon can re-aggravate existing injuries and prolong recovery. Examples include:

  • Knee replacement surgeries
  • Ankle instability after sprains
  • Low back disc injuries or arthritis
  • Heel spurs
  • Achilles tendon ruptures
  • Stress fractures
  • Plantar fasciitis

To prevent re-injury:

  • Consult doctor or physical therapist about when it is safe to resume stair climbing after an injury
  • Use recommended brace or orthotic as needed for extra support
  • Start very gradually upon return like 1-2 flights per day
  • Take extra rest days early in the return to climbing process
  • Ice any sore or painful areas after climbing
  • Consider alternative cardio like swimming ifstairs aggravate injury

Increased Fatigue and Shortness of Breath

Frequently climbing several flights of stairs can be exhausting and lead to increased fatigue and shortness of breath, also known as dyspnea. Contributing factors include:

  • Insufficient cardiovascular fitness
  • Excess body weight
  • Underlying respiratory conditions like asthma
  • Anemia or deficiency in red blood cells
  • Electrolyte imbalances
  • Allergies to dust or mold in stairwells

Ways to prevent:

  • Improve cardiovascular endurance with aerobic exercise
  • Maintain a healthy body weight
  • Use an inhaler if prescribed prior to climbing for asthma
  • Have iron levels tested and supplement if anemic
  • Stay hydrated and replenish electrolytes
  • Take breaks as needed when climbing long flights

Increased Muscle Mass Asymmetry

Climbing stairs primarily works the lower body, often leading to greater development of muscle mass in the legs versus the upper body. Over time this can create aesthetic muscle imbalances or asymmetries. Contributing factors include:

  • Climbing stairs frequently without upper body training
  • Genetic predisposition to develop more lower body mass
  • Carrying objects primarily on one side upstairs

Prevention tips:

  • Include upper body strength training exercises like push-ups and rows
  • Change direction or take alternating stairs to work both legs evenly
  • Switch between carrying objects on left and right side
  • Assess muscle mass distribution and adjust stair training if needed

Increased Risk of Stress Fractures

The bones of the lower body are subject to significant repetitive impact forces when climbing stairs frequently. Over time, excessive levels can contribute to stress fractures. These small cracks or fissures in the bone require rest to heal properly. Common sites include:

  • Metatarsals in the feet
  • Tibia or shin bone
  • Fibula
  • Femur
  • Pelvis

Risk factors:

  • Sudden increases in stair training frequency, duration, or intensity
  • Low calcium, vitamin D, or other nutritional deficiencies
  • Female athlete triad hormonal issues
  • Hard surfaces like concrete stairs
  • High foot impact forces
  • Improper footwear

Prevention strategies:

  • Build up stair climbing volume gradually over time
  • Optimize nutrition and bone health
  • Wear shock-absorbing shoes
  • Consider adding low-impact exercise like swimming
  • Take rest days for bone recovery

Increased Risk of Accidents

Distractions, haste, cluttered stairs, inadequate lighting, and other hazards can increase accident risk when climbing multiple flights of stairs frequently. Potential injuries include:

  • Sprains and fractures from falls
  • Head injuries like concussions
  • Cuts and abrasions
  • Jammed fingers or toes
  • Muscle strains from trying to catch oneself

Accident prevention tips:

  • Remove clutter and install adequate lighting in stairwells
  • Put away or secure mobile devices when using stairs
  • Install and use handrails for support
  • Wear slip-resistant shoes
  • Supervise young children on stairs
  • Report any hazards to property owners promptly


In summary, frequently climbing stairs can lead to several potential side effects primarily involving the lower body including muscle soreness, joint pain, ligament sprains, back pain, and an increased risk of overuse injuries and falls. However, most risks can be minimized by gradually increasing stair climbing volume, using proper form, wearing appropriate footwear, building muscle strength and endurance, taking rest days, and addressing any underlying medical issues. Adding upper body training and cross-training activities like swimming is also recommended to promote balanced physical development. With appropriate precautions and monitoring of any negative reactions, most individuals can safely incorporate stair climbing into their regular exercise routine and gain significant health benefits such as improved cardiovascular fitness.
