Arms above the head: compromised circulation
Some people sleep with their arms extended above their head or tucked under their pillow. However, this position is not without its consequences: nerve compression, which causes tingling or numbness in the arms, and shoulder tension, which can reduce mobility in the long run. If you frequently experience tingling upon waking, consider repositioning your arms to avoid this compression.
The fetal position too curled up: a trap for the spine
Sleeping on your side is a common position, but curling up too much can be harmful to your health. When your knees are too close to your chest and your chin is tucked in, you risk compressing your lungs, reducing your breathing capacity, creating excessive curvature of the spine, and losing flexibility in the long run. Opt for a more relaxed side position, with your knees slightly bent, for greater comfort.
The ideal position: sleeping on your left side
Many experts agree that sleeping on your left side is beneficial for several reasons: it improves digestion, as gravity helps the stomach function efficiently; it promotes blood circulation, ideal for pregnant women or people with high blood pressure; it reduces acid reflux by keeping the stomach in a stable position; it relieves spinal strain by providing natural alignment that prevents back pain; and it improves breathing, especially helpful if you snore or have sleep apnea. If this position is unfamiliar to you, use a body pillow to help you stay on your left side all night.
