9.2 Role of Yoga in the Management of Non-Communicable Diseases (Syllabus 3.14)
Key Takeaways
WHO reports that non-communicable diseases cause about 74% of deaths worldwide; about 17 million people die from an NCD before age 70 each year, 86% of them in low- and middle-income countries.
WHO lists five shared NCD risk factors: tobacco use, physical inactivity, harmful use of alcohol, unhealthy diet and air pollution; the linked metabolic changes are raised blood pressure, overweight, raised glucose and raised lipids.
India's NCD programme began in 2010 as NPCDCS and was renamed the National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD) in 2023.
Common diagnostic thresholds: hypertension at 140/90 mmHg or higher (130/80 in the 2017 US guideline); diabetes at fasting glucose of 126 mg/dL or higher or HbA1c of 6.5% or higher; obesity at BMI 25 or higher for Asian Indians (30 in the WHO global cut-off).
Yoga helps by addressing modifiable risk factors and stress alongside medical treatment; instructors never alter medication and watch for hypoglycaemia, chest pain and other warning signs.
Role of Yoga in the Management of Non-Communicable Diseases
Quick Answer: Non-communicable diseases (NCDs)—mainly cardiovascular disease, cancers, chronic respiratory disease and diabetes—cause about 74% of deaths worldwide (WHO). They share modifiable risk factors that Yoga addresses directly: physical inactivity, unhealthy diet, tobacco and alcohol use, and chronic stress. Yoga's role is prevention and supportive management alongside medical care. India's national programme (NP-NCD, renamed from NPCDCS in 2023) focuses on screening and early treatment, which an instructor supports by encouraging check-ups and healthy routines.
What NCDs are
NCDs are long-lasting conditions that are not passed from person to person; they result from a mix of genetic, physiological, environmental and behavioural factors.
- Burden (WHO): about 74% of all deaths worldwide; about 17 million people die from an NCD before age 70 each year, 86% of them in low- and middle-income countries.
- Main groups: cardiovascular diseases (heart attack, stroke), cancers, chronic respiratory diseases (COPD, asthma) and diabetes.
- Shared risk factors (WHO): tobacco use, physical inactivity, harmful use of alcohol, unhealthy diet and air pollution.
- Metabolic risk factors: raised blood pressure, overweight and obesity, raised blood glucose and raised blood lipids.
- India: the ICMR State-Level Disease Burden study estimated that NCDs caused about 62% of deaths in 2016. The National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) began in 2010 in 100 districts and now covers the whole country; in 2023 it was renamed NP-NCD and widened to conditions such as chronic kidney disease and non-alcoholic fatty liver disease. Population screening for common NCDs in adults aged 30 and over is a core activity.
Why Yoga fits NCD prevention
| Risk factor | Yogic response |
|---|---|
| Physical inactivity | Regular Asana, Surya Namaskara, Sthula Vyayama |
| Unhealthy diet | Mitahara, Sattvika Ahara, mindful eating |
| Chronic stress (Adhi) | Relaxation, slow breathing, Dhyana, the four Bhavanas (PYS 1.33) |
| Tobacco and alcohol | Self-awareness, Pratyahara, group support (Satsanga)—alongside, not instead of, cessation services |
| Irregular routine and poor sleep | Dinacharya, Yoga Nidra |
| Overweight | Activity, diet and awareness together |
Seen through the Adhi-Vyadhi model, many lifestyle diseases begin as stress and faulty habits before they become physical disease, so Yoga works at the source as well as on the body.
Key NCDs: thresholds, emphasis and cautions
| Condition | Diagnostic threshold (for orientation) | Yogic emphasis | Cautions |
|---|---|---|---|
| Hypertension | 140/90 mmHg or higher in Indian and International Society of Hypertension (2020) guidance; 130/80 in the 2017 US ACC/AHA guideline | Relaxation, slow breathing without retention, Bhramari, Shavasana, gentle Asanas, salt moderation | No inversions, Kumbhaka, Kapalabhati or Vamana Dhauti; avoid strenuous Sthula Vyayama if uncontrolled |
| Type 2 diabetes | Fasting plasma glucose 126 mg/dL or higher, HbA1c 6.5% or higher, or 2-hour glucose 200 mg/dL or higher; prediabetes (ADA) 100–125 mg/dL fasting or HbA1c 5.7–6.4% | Regular moderate activity (Surya Namaskara, standing poses), twists and abdominal postures, weight and stress management, Mitahara | Risk of low blood sugar on insulin or some tablets—do not practise fasting for long, keep sugar at hand; foot care; avoid strain and inversions with eye disease |
| Obesity | BMI 25 or higher (WHO overweight) and 30 or higher (obese); for Asian Indians, 23 or higher overweight and 25 or higher obese, waist 90 cm or more in men and 80 cm or more in women (Indian consensus, 2009) | Dynamic practice, repeated rounds of Surya Namaskara, Mitahara, routine | Protect knees and back; watch breathlessness |
| Coronary heart disease | Diagnosed by a doctor | Only with a cardiologist's clearance, as part of cardiac rehabilitation: gentle practice, relaxation, slow breathing | No Kumbhaka, inversions or strenuous effort; stop at once with chest pain or breathlessness |
| COPD and asthma | Diagnosed by a doctor | Pursed-lip and slow exhalation, sectional breathing, chest-opening postures | No cooling Pranayama; practise only when stable |
| Cancer (supportive care) | Diagnosed by an oncologist | Gentle practice and relaxation for fatigue, anxiety, sleep and quality of life | Never presented as a cure; adapt to treatment; avoid pressure on surgical sites and ports; infection precautions |
How Yoga helps—and its limits
Yoga adds regular physical activity, which improves insulin sensitivity and blood pressure; reduces stress-system activation; supports weight and waist control, sleep and routine; and builds health awareness and confidence in self-care. Trials that add Yoga to usual care report modest improvements in blood pressure and blood sugar, though study quality varies.
Scope reminders: never change medication; encourage regular screening and follow-up; keep records of any readings participants share; and stop and refer at any warning sign.
Worked example: reading a participant's numbers
A 50-year-old participant shares a recent check-up: blood pressure 146/94 mmHg, fasting plasma glucose 112 mg/dL, weight 78 kg and height 1.70 m.
- Blood pressure: 146/94 is at or above 140/90, so it falls in the hypertensive range under Indian and international guidance. Encourage a doctor's review; meanwhile teach relaxation and slow breathing without retention, and avoid inversions and Kapalabhati.
- Glucose: 112 mg/dL fasting lies in the 100–125 mg/dL range the ADA calls prediabetes (below the 126 mg/dL diabetes threshold). Regular activity, Mitahara and weight control are exactly where Yoga helps, alongside medical follow-up.
- BMI: 1.70 × 1.70 = 2.89; 78 ÷ 2.89 ≈ 27.0. That is "overweight" by the WHO global cut-off (25–29.9) but "obese" by the Asian Indian cut-off (25 or higher). Add waist measurement for a fuller picture.
The instructor does not diagnose: the purpose is to recognize when a medical review is needed and to choose safe practices meanwhile.

During an early-morning class, a participant with type 2 diabetes who uses insulin and skipped breakfast becomes shaky, sweaty and confused. What should the instructor do first?
Continue with rapid Kapalabhati so that the extra effort raises blood sugar and the person's energy
Guide them into Shavasana and begin a full Yoga Nidra until the symptoms settle
Ask them to hold the breath for a few seconds to steady the racing heart
Stop, give fast-acting sugar if they can swallow, and get medical help if they do not recover
