Sleep position, bedroom temperature, and other bedtime factors can all be asthma triggers.

Elevating your neck and shoulders with two, three, or more pillows can open up your airways as you sleep. If your sinuses drain more during the night, sleeping with pillows under your shoulders gives the drainage a gravity boost so that you can keep breathing easy while you sleep.

If you’re a side sleeper with asthma, lying on your left side may help — particularly if you have gastroesophageal reflux, also known as heartburn, which can trigger asthma especially at night. Sleeping on your left side uses gravity, the shape of the stomach, and the angle of the connection between it and the esophagus, which can reduce reflux. Lying on your left side with your head elevated may be enough to keep you comfortable through the night, but if it’s not, experiment by adding a pillow between your legs.

For some people, sleeping in the side position is just too much of a change. If you prefer sleeping on your back with your head and shoulders propped up by pillows, you can add another pillow under your knees.
