You're Taller in the Morning Than at Night
You can be up to 1-2 cm taller in the morning due to spinal disc decompression during sleep.
The Shrinking Day
Throughout the day, gravity compresses your spine. At night, it decompresses. This makes you measurably taller in the morning.
The Science
Your spine contains:
- 23 intervertebral discs
- Gel-like material that absorbs shock
- Cartilage that compresses under weight
- Fluid that redistributes when lying down
The Numbers
Most people:
- Lose 1-2 cm of height during the day
- Regain it during sleep
- Experience maximum compression by evening
- Recover height after 7-8 hours lying down
Astronauts in Space
Without gravity, astronauts can grow up to 5 cm taller! Their spines fully decompress in microgravity.
Practical Impact
This is why:
- Doctor's appointments should be consistent times
- Height measurements vary by time of day
- Athletes feel stiffer in the evening
- Morning is best for measuring true height
