4. Dehydration
Dehydration is a more serious condition than many people realize and can cause a lot more problems than you might expect. For instance, if you are very dehydrated, then you might find that you experience serious headaches as your brain actually shrinks and pulls itself away from the inside of your skull.
But did you know that this can also increase the likelihood of herniated discs? A moist intervertebral disc is lubricated and capable of squashing and changing shape. When this dries out, it becomes brittle and significantly more likely to tear or rupture.
Keep drinking lots of water then, and especially during exercise during which time you might be more likely to move awkwardly and be highly dehydrated.
