Sleep disturbances, like insomnia, may result from hormonal, digestive, or detoxification issues within the body. Melatonin, an adrenal hormone that regulates sleep, is also important for immune system functioning. Low levels of melatonin in early morning hours can cause people to wake up between 2 AM and 4 AM. Lab testing can show you if your melatonin or other adrenal hormones are out of balance. Female hormone imbalances may be another reason for sleep problems, especially if progesterone is low. Digestive concerns can appear when your diet is low in minerals like magnesium and calcium which are very important for helping you relax and sleep. Stomach acidity is important for ensuring that your body is able to properly use those essential minerals to help with sleep. Poor digestion can also lead to low levels of serotonin, a neurotransmitter that helps with restful sleep. The liver, which responsible for detoxification is most active between 1 AM and 3 AM. If overwhelmed, the liver’s detoxification system may result in headaches or even nightmares that can disturb your sleep cycle. It is essential to have the appropriate lab testing to identify why you may be experiencing sleep disturbances and to understand how to treat it.
