Sleeping left-side down with your head and torso elevated is often suggested as a way of preventing night-time reflux.

Studies have identified a relationship between laying on the right side and increased cases of reflux symptoms, such as heartburn, compared to when laying on the left side.

In one study, the total amount of reflux time was significantly greater with subjects in the right sleeping position than in the left.  While another connected right-side sleepers with greater acid levels and longer ‘oesophageal acid clearance’.

Some researchers suggest that if we lie on the left side, the stomach and its gastric juices remain lower than the oesophagus while we sleep. It is also proposed that when the oesophagus is above the stomach, it leads to a relaxation of the lower sphincter muscle.

Now, Side Sleep Technologies (SST), a Dutch digital health startup, has developed wearable technology to train people to sleep on their left side.

The LEFT Device is designed to work by ensuring that the stomach is positioned below the oesophagus so that ‘gravity works to keep acid in the stomach’.

It is placed on the breastbone before sleeping using specially designed hypoallergenic stickers. Once it detects that someone is sleeping on their right side, it will vibrate. In addition, using the LEFT app, users can access their sleep position data via Bluetooth.

The LEFT Device is available to buy online – currently at £29.99.
