Always feeling tired and groggy? Constant fatigue may be linked to a hidden hormonal imbalance. Our endocrine system helps to regulate our hormones, which are sensitive to changes in our sleep routine. Conversely, our hormones control our energy, metabolism, and even our moods – all of which play a role in the quality of our sleep. Therefore, our hormones and sleep patterns both affect one another. Breaking this cycle lies in understanding the endocrine system and balancing both hormones and sleep patterns to correct the issue. For example, the endocrine system controls almost every process within the body. Within it are our adrenal glands and pineal gland, the smallest endocrine gland. When the adrenal glands are overworked, anxiety follows, keeping us up at night. Moreover, the pineal gland controls the release of the sleep hormone melatonin based on exposure to light within the environment obtained through the eyes. To balance our fatigue, we must balance our hormones, and vice-versa.
