Back Pain After a Sleep In

How much time do you spend in bed each night? Does your back hurt after you treat yourself to a sleep in on the weekend? Did you know that night time is when your spinal discs rehydrate and renourish themselves? You're taller in the morning due to this and throughout the day your spinal discs become dehydrated so you're shorter at night. 

The ideal amount of time required to rehydrate and re-nourish your spinal discs at night is 8 hours of bed rest. Less than 8 hours means your spine doesn't receive enough inflow to get adequate nutrition. Any more than this and your discs continue to swell and can become damaged under stress. Both too much or too little predisposes you to pain and spinal injury.
