Feel like you were taller last time you checked? You’re not imagining it: we do actually shrink during the day as the cartilage in our spine compresses, making us 1½-2cm shorter. Thankfully, as we sleep, the pressure on our spine eases and we regain the lost height in the morning.
However, over time the effects do become permanent, and that, along with flatter feet and loss of muscle mass, means we can lose up to 5cm in height by the time we are 70.
