Dehydration and Electrolyte Imbalance
Dehydration significantly increases your risk of developing muscle spasms in back. When your body lacks adequate fluids and essential electrolytes like magnesium, potassium, and calcium, your muscles become more prone to cramping and spasms.
Poor Posture and Sedentary Lifestyle
Modern work environments often contribute to back problems. Prolonged sitting with poor posture places excessive stress on your spine and supporting muscles, creating conditions that predispose you to back spasms.
Underlying Medical Conditions
Certain conditions such as herniated discs, spinal stenosis, arthritis, and nerve compression can trigger muscle spasms in back as your body attempts to protect injured or inflamed tissues.
