Then, when those defenses aren't used, you become anxious. Perhaps you aren't getting enough sleep, or the right kind of sleep. You may have insomnia, or a host of other sleep-related problems. People with FMS often have the alpha-delta sleep anomaly. Our body heals and many neurotransmitters are restored during delta sleep, so we soon suffer from the effects of sleep deprivation.
Neurotransmitters are electro-biochemical agents that cross nerve synapses.
They are the vehicles that carry information back and forth between your body and mind. Much of our mental and physical sense of continuity and security depends upon our ability to repeat appropriate and predictable actions. Neurotransmitters normally inform muscles constantly about what they're doing, so their actions can be modified. Much of our muscle tension function is improperly controlled by these neurotransmitters. Healthy people think nothing of picking up a glass of water and bringing it to their lips.
