It is important for parents to know how to keep their child’s back healthy, how to choose the right bag, and how to distribute items to prevent postural problems and pain.

How heavy should a school bag be?
Specialists recommend that a school bag should not exceed 10–15% of a child’s body weight.

• For example, for a child weighing 30 kg, the maximum bag weight should be 3–4.5 kg.

Possible effects of carrying a heavy bag:

• Muscle tension in the shoulders, back, and neck

• Improper spinal posture and deformation over time

• Fatigue and reduced concentration in school

Correct way to carry a school bag

1. Use both shoulders:
   Carrying a bag on one shoulder causes body asymmetry and overloads muscles on one side. Children should learn to carry the bag evenly on both shoulders to maintain proper spinal posture.

2. Bag height:
   The bag should sit at the middle of the back—not too high or too low. Excessively high or low positioning creates asymmetry and increases tension.

3. Strap adjustment:
   Bag straps should be tight enough so that the bag fits snugly against the body. Loose straps overload the supporting muscles.

4. Internal organization:
   Heavy items should be placed close to the back, while lighter items go further out. Only necessary books and items should be in the bag.

Internal Bag Organization

• Only necessary items: Pre-select what the child needs to carry each day.

• Even weight distribution: Place heavy books toward the back, lighter items toward the front.

• Water bottle, snacks, sportswear: Distribute regularly so the bag doesn’t become too heavy.

Recommendations for Parents

1. Daily weight check:
   Check your child’s bag daily and redistribute or reduce physical items if needed.

2. Teach proper carrying habits:
   From the beginning, teach your child to use both shoulders, adjust straps, and organize books correctly.

3. Include physical activity:
   Regular sports, exercises, and muscle strengthening have a significant impact on spinal health.

4. Monitor posture:
   Regularly check your child’s spine. Pay attention to whether they slouch or have pain in the shoulders, back, or neck.
