Sleep is essential for overall well-being. It’s when your body resets, repairs tissues, and restores energy. However, your sleeping position can significantly affect your health—sometimes negatively—without you even realizing it.

The Sleeping Position Experts Warn Against: Lying on Your Back

Many people consider back sleeping ideal for posture, but for certain conditions, it can be harmful. Here’s why:

1. Increases Risk of Sleep Apnea
Lying flat on your back can cause your tongue and soft palate to collapse backward, partially blocking the airway. This leads to snoring, interrupted breathing, and in severe cases, dangerous drops in oxygen levels—particularly in people with undiagnosed obstructive sleep apnea.

2. Spinal Misalignment and Back Pain
Without proper lumbar support, back sleeping can flatten the natural curve of your lower spine. This stress can cause neck and shoulder tension, morning stiffness, or headaches that linger throughout the day.

3. Triggers Acid Reflux and GERD
Back sleeping can worsen heartburn or gastroesophageal reflux. Stomach acid can easily flow back into the esophagus, causing discomfort and disrupting sleep.
