How Sleep Position Influences Digestion at Night

Digestion doesn't stop when we fall asleep. The position adopted during the night plays an important role in how the stomach and esophagus function. An unsuitable posture can slow digestion and increase discomfort, while a slight elevation of the upper body can promote better digestive comfort.

1. What Does Digestion Do While We Sleep?

Even during sleep:

  • the stomach continues to digest food
  • gastric juices remain active
  • digestive movements continue
  • the body still processes the evening meal

Nocturnal digestion is slower, making posture even more important.

2. Why Is Digestion More Sensitive at Night?

At night, several factors come into play:

  • less body movement
  • a calmer metabolism
  • a prolonged position
  • reduced vigilance against discomfort

This can make digestive sensations more noticeable and sometimes more bothersome.

3. How Does the Lying Position Influence Digestion?

When lying completely flat:

  • gravity no longer helps the stomach contents
  • food remains longer in a horizontal position
  • gastric juices can rise more easily
  • the esophagus is more exposed to irritation

This position can slow digestive comfort, especially after dinner.

4. Why Do Some People Experience More Reflux at Night?

This may be related to:

  • late meals
  • foods that are difficult to digest
  • individual sensitivity
  • stress
  • an unsuitable posture

Even without a permanent digestive problem, these factors can cause nighttime discomfort.

5. What Role Does Posture Play in Digestive Comfort?

Posture influences:

  • the natural direction of gastric juices
  • the pressure on the stomach
  • how easily food stays in place
  • the overall sensation of comfort

An adapted posture helps the body to digest more peacefully.

6. Why Can a Slight Elevation of the Upper Body Help?

When the upper body is slightly elevated:

  • gravity helps keep stomach contents down
  • pressure on the esophagus decreases
  • the sensations of rising are often reduced
  • the body remains in a resting position

Even moderate elevation can improve the feeling of comfort.

7. How Does CosyLift Support More Comfortable Digestion at Night?

CosyLift allows for the regular elevation of the upper mattress, which:

  • promotes a posture more suited to digestion
  • avoids pillow instability
  • supports the entire upper body
  • allows position adjustment according to needs
  • contributes to a more peaceful sleep

It is a simple solution, based on posture and gravity.
