Sleeping places that are polluted by earth rays and electrosmog can cause a slight tension of the muscles during sleep.
The spine should be 1 to 2 cm longer in the morning because the intervertebral discs can easily recover and expand during the night. If the muscles remain slightly tense during sleep, the recovery of the intervertebral discs is reduced and you get up in the morning feeling tired.
Over time, this leads to back pain in the lower back, herniated discs and tense shoulder and neck muscles.
If back pain persists for a long time, you should have the sleeping place checked for electrosmog and earth radiation. In modern building biology there are good possibilities today to physically protect a sleeping place from electrosmog and earth radiation.
On the protected sleeping place, it usually takes 4 to 6 months for the muscles to relax again and for the intervertebral discs to regain their normal elasticity.
