Class 12 Physical Education Chapter 3:Yoga as Preventive Measure for Lifestyle Disease

Topic 1: Meaning of Asana and its Benefits

1. What is an Asana?

According to the great sage Patanjali (the father of Yoga), Asana is defined as “Sthiram Sukham Asanam”, which means “that position which is comfortable and steady.” In simple terms, an Asana is a body posture that can be held comfortably for an extended period of time.

2. How Yoga Prevents Lifestyle Diseases

Lifestyle diseases (like Obesity, Diabetes, Asthma, and Hypertension) are mostly caused by an inactive daily routine, stress, and poor eating habits. Regular practice of Asanas helps prevent these diseases by:

Improving Digestion: Massages the internal abdominal organs, which helps in better digestion and insulin production.

Strengthening Muscles and Joints: Keeps the body physically active and flexible.

Improving Respiratory System: Deep breathing in yoga increases lung capacity.

Regulating Blood Pressure: Calms the nervous system and reduces mental stress.

Topic 2: Obesity and its Preventive Asanas

1. What is Obesity?

Obesity is a medical and lifestyle condition in which excess body fat has accumulated to the extent that it may have a severe negative effect on health. A person is generally considered obese when their Body Mass Index (BMI) is 30 or higher.

3. Pranayam for Obesity: Surya Bhedi Pranayam (Right Nostril Breathing)

What is Surya Bhedi Pranayam? In Yoga, the human body has two main energy channels: the Surya Nadi (Right nostril, representing solar energy and heat) and the Chandra Nadi (Left nostril, representing lunar energy and coolness). “Surya Bhedi” translates to piercing or activating the solar channel. In this Pranayam, inhalation is always done through the right nostril, and exhalation through the left. This deeply activates the body’s fire element, boosting metabolism and aiding in rapid weight loss.

Procedure:

1. Sit in a comfortable meditative posture like Padmasana, Sukhasana, or Vajrasana.
2. Keep your spine, neck, and head perfectly straight and close your eyes.
3. Rest your left hand on your left knee in Gyan Mudra (joining the tips of the index finger and thumb).
4. Bring your right hand to your face. Use your right thumb to close your right nostril. (Wait, correct method: use right thumb to close LEFT nostril to inhale from RIGHT). Correction: Use your right ring/little finger to close your left nostril.
5. Inhale slowly and deeply through your right nostril.
6. (Optional for advanced practitioners: Hold your breath inside for a few seconds).
7. Now, close your right nostril with your right thumb, open the left nostril, and exhale slowly through the left nostril.
8. This completes one cycle. Remember: Always inhale from the right and exhale from the left. Repeat this process for 5 to 10 minutes.

Benefits:

1. It significantly boosts the basal metabolic rate (BMR), helping the body burn excess fat and calories much faster.
2. It generates internal heat, which clears the sinuses, cures cold/cough, and helps asthma patients.
3. It energizes the nervous system, removes lethargy, and is highly beneficial for individuals suffering from low blood pressure.

Contraindications:

1. Because it generates intense body heat, people suffering from High Blood Pressure or heart diseases must strictly avoid it.
2. Individuals suffering from high fever, acidity, or peptic ulcers should not practice it.
