Discussion: Sleep disorders are often related to the subconscious mind and cannot be cured with medication.

The pineal gland in the brain, the ruler of the subconscious Mind, also regulates sleep cycles through the hormone melatonin. Sleep disturbances often originate from unresolved traumas that reside in the subconscious Mind. Various drugs, some of which are tranquilizers from the Valium family, do not solve the problem in depth. The mattress and how we sleep are essential for sleep comfort, but not in the context of sleep disturbances.
