A typical workday can involve hours at a desk, a commute by car and an evening spent on the sofa. While this routine may feel normal, spending too much time sitting can leave little room for the movement your body needs.
Musculoskeletal health covers your bones, muscles, joints, tendons and ligaments. These structures help you move comfortably, maintain balance and carry out daily activities. Although age affects their strength and function, physical activity, nutrition and other lifestyle habits also play an important role.
As desk-based work becomes more common, making movement part of everyday life is increasingly important.
How Common Is Physical Inactivity?
Physical inactivity is a growing public health concern. The World Health Organization (WHO) reported that around 31% of adults worldwide did not meet recommended physical activity levels in 2022.
In India, the WHO's 2024 country profile reported insufficient physical activity among 49.4% of adults.
How Does a Sedentary Lifestyle Affect Your Bones and Muscles?
Your body needs regular movement to maintain strength, flexibility and coordination. When physical activity is limited, several changes can affect your ability to move comfortably.
1. Muscle weakness and stiffness: Prolonged sitting can contribute to muscle deconditioning, particularly when you rarely exercise. Poor workstation ergonomics and repetitive movements may also contribute to neck, shoulder and lower back discomfort.
Taking movement breaks and adjusting your workstation can help reduce unnecessary strain.
2. Reduced bone strength: Bones are living tissues that continually renew themselves. Weight-bearing activities and resistance exercises provide mechanical stimulation that helps maintain bone strength.
Insufficient physical activity can contribute to bone loss, particularly when combined with inadequate nutrition, certain medical conditions or other risk factors for osteoporosis.
3. Reduced mobility and balance: Limited activity can affect flexibility, physical endurance and balance. Everyday tasks, such as climbing stairs, carrying groceries or getting up from a chair, may become more difficult when muscle strength declines.
Calcium and Vitamin D: Why Both Matter
Exercise helps bones respond to physical demands, but nutrition provides the materials needed to maintain them.
Calcium for bone strength: Calcium is the main mineral in bones and teeth. If your diet consistently lacks calcium, your body may draw on its stored supply to maintain normal blood calcium levels.
Include calcium-rich foods such as:
- Milk, curd and paneer
- Ragi and sesame seeds
- Amaranth and other suitable green leafy vegetables
Vitamin D for calcium absorption: Vitamin D helps your body absorb calcium. Severe deficiency can interfere with bone mineralisation and contribute to bone disorders.
Sunlight supports vitamin D production, but the amount your body makes depends on factors such as skin tone, season, location and time outdoors. Oily fish, egg yolks and fortified foods are additional sources.
Five Practical Ways to Protect Musculoskeletal Health
You do not need an elaborate fitness routine to begin. Focus on changes you can maintain consistently.
1. Break up long sitting periods: Stand, stretch or take a short walk between meetings. Walk while taking phone calls when practical, and use breaks to move rather than remaining seated.
2. Combine aerobic activity with strength training: The WHO recommends that adults aim for 150 to 300 minutes of moderate-intensity aerobic activity each week, alongside muscle-strengthening activities on at least two days.
Depending on your fitness and health, suitable activities include:
- Brisk walking or dancing
- Squats and lunges adapted to your ability
- Resistance-band exercises or weight training
- Stair climbing, if comfortable
- Balance exercises to improve stability
Start gradually and increase activity as your strength and endurance improve.
3. Improve your workstation: Adjust your chair and screen to a comfortable height, keep your feet supported and position frequently used items within easy reach. Good ergonomics can reduce strain, but regular movement remains essential.
4. Eat a balanced diet: Include adequate protein, calcium-rich foods, fruits, vegetables and other nutrient-dense foods. Protein supports muscle maintenance, while calcium and vitamin D contribute to bone health. Avoid crash diets that make it difficult to meet your nutritional needs.
5. Avoid habits that weaken bone health: Smoking and excessive alcohol consumption are associated with poorer bone health. Adequate sleep, regular exercise and a balanced diet also support overall musculoskeletal function.
If you have persistent pain, recurring stiffness or difficulty moving, seek medical advice instead of assuming the symptoms are caused by sitting or ageing.
Who May Need Additional Bone Health Assessment?
Some people have a higher risk of bone loss and may benefit from an individual assessment. Risk factors include:
- A fracture following a minor injury
- A family history of osteoporosis or hip fractures
- Persistently low body weight or a history of eating disorders
- Early menopause or certain hormonal conditions
- Long-term use of steroid medicines
- Conditions that interfere with nutrient absorption
A bone density scan is not routinely necessary for every healthy adult in their 30s. A doctor can assess your risk factors and recommend testing when appropriate.
