Lockdown could be bad for your back. Thanks to measures to tackle the coronavirus pandemic, many of us are now working from home. This means you might not be moving around as much, and your home desk setup (and the posture you adopt while working) might not be as good as it should be. These are all things that can lead to back pain.
Common poor desk posture is actually very similar to the posture astronauts adopt during spaceflight in zero-gravity. Usually, this is a forward-leaning posture with a forward head position and the loss of normal spinal curves. Being in space also has similar effects to staying in bed all day.
