CR underlies sleep, mood (including depression and PTSD), energy, and binge eating behaviors. Bipolar disorder is a CR disorder, and by balancing CR, we can make significant progress. Disrupted CR is a disease of modern life; our ancestors went to sleep in the dark (or had dimly lit fires, candles, or lanterns) and woke up with the light. They often awakened in the middle of the night around 3 a.m. and spent an hour in reverie, integrating visions and dreams into their lives before dozing back to sleep.<\/p>\n\n\n\n<p>I am always eager to read new research on circadian rhythm. The first study examines the connection between glucose, diabetes, and disrupted circadian rhythm. Here, we have two modern diseases intersecting: Type 2 Diabetes, which rarely, if ever, occurred prior to the late 19th century, and circadian disruption due to artificial light. Ironically, the rise of access to refined sugar and increased cases of Type 2 Diabetes in the 1930s coincides with the electrification of the United States in rural areas.<\/p>\n\n\n\n<p>The second research paper looks at the age of menarche onset, which occurs relatively earlier in urban females than in females raised in rural areas in Nigeria. This effect of earlier age of onset is also seen in the United States with exposure to pesticides and chemicals that act as endocrine disruptors.<\/p>\n\n\n\n<p>My clients often ask how long I recommend they take nutrients or detoxify. I answer, \u00abHow long will you be exposed to multiple toxins and stressors?\u00bb<\/p>\n\n\n\n<p>Article 3 leads us to the role of disrupted CR and cancer. It is well-established that people who work the night shift have a higher risk of cancer. CR imbalance contributes to tumor development. <\/p>\n\n\n\n<p>The fourth research paper highlights how, in addition to the sleep-wake cycle and stress hormone rhythms, CR also contributes to the reward system\u2014so it makes sense that disruption to sleep contributes to substance abuse. We know that PTSD and the strong association between PTSD and substance abuse also disrupts CR.<\/p>\n\n\n\n<p>This review of circadian rhythm research suggests that a balanced rhythm governs all paths to mental and physical health. Stabilizing sleep is our first goal in treating mental distress. I trust you&#8217;ll find these articles both accessible and valuable.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Balancing the circadian rhythm (CR) is the quintessential health goal, ensuring good mental and physical health.
