Why is the left side considered the best?
An ally for your spine and breathing
Sleeping on your left side allows the spine to stay naturally aligned. The result: less tension, better support for the hips and back, and therefore a more serene awakening. But that’s not all. This position also promotes better breathing. According to health specialists, it optimizes the flow of air to the lungs, which can be a real relief for people prone to snoring or sleep apnea.
A boost for your digestion
Have you ever felt that famous “crash” after a heavy meal? This feeling of heaviness often comes from slowed digestion. However, sleeping or lying on your left side for a few minutes after a meal can help a lot. What for? Because the stomach and pancreas are located on the left: in this position, digestive juices circulate more naturally, and food progresses faster through the digestive system. It’s a bit like following the current of a river rather than swimming against the current.
Facilitated lymphatic drainage
The lymphatic system, which is often misunderstood, plays an essential role in the elimination of toxins. And surprise: the majority of this network is located… on the left flank! By sleeping on this side, you facilitate the work of your heart, your spleen, and your lymph nodes, all positioned on this side. Gravity does the rest, naturally supporting drainage. It’s a bit like your body going into “spring cleaning” mode overnight.
Can you really change your sleeping position?
Changing a habit as ingrained as sleeping in can seem difficult. And for good reason: your body has its well-established reflexes. Sleep specialist Dr. Steven Park advises taking it easy. Rather than forcing a drastic change, gradually test sleep on the left flank. For example, you can prop up a cushion on your back to avoid rolling over during the night. With a little patience, your body will get used to it naturally.
A little trick that can change everything
As is often the case with well-being, it is the simplest gestures that make all the difference. Sleeping on your left side requires no physical effort or expensive equipment. It is a habit accessible to all, to be adopted gradually to observe its benefits. Better digestion, a less painful back, deeper sleep… What more could you ask for?
