As the body's primary stress hormone, cortisol surges when we perceive danger, and causes all the symptoms we associate with “fight or flight”—increased blood pressure and heart rate, muscle tension, and the digestive system slamming to a halt, resulting in nausea, vomiting, and diarrhea.
Weakened muscles. Mood swings, anxiety, depression, or irritability. Increased urination.
Low cortisol levels can cause any of the following symptoms: Fatigue and morning sluggishness. Depression. Anxiety.
If a person believes they have high or low cortisol levels, they may wish to take a cortisol test. Usually, these tests take place at a medical practice. However, several at-home cortisol tests are available to purchase. A person can take these tests at home by providing a urine, blood, or saliva sample.
Medicines to control cortisol production at the adrenal gland include ketoconazole, osilodrostat (Isturisa), mitotane (Lysodren), levoketoconazole (Recorlev), and metyrapone (Metopirone). Mifepristone (Korlym, Mifeprex) is approved for people with Cushing syndrome who have type 2 diabetes or high blood sugar.
Adrenal gland tumors or disease.
Problems with the adrenal glands can cause them to make too much cortisol. The most common is a tumor in the outer part of the adrenal gland called an adrenal adenoma. These tumors are not cancer, and only some make too much cortisol.
In humans, the peak level secretion occurs in the morning (07:00–08:00 a.m.), which is considered the active phase, while its lowest secretion is around 02:00–04:00 a.m. at night [44,47]. Figure 2 demonstrates the circadian rhythm of cortisol.
Various factors can cause high cortisol levels. But the biggest culprits on the list are sleep insufficiency, chronic stress, circadian misalignment, high-intensity exercise or overtraining and certain medical conditions like Cushing's disease.
The main cause here is stress and high cortisol levels. See, our circadian rhythm directs our cortisol, an awakening hormone, to rise around 3am, in preparation for the next morning. However, if you cortisol levels are already high, which is a consequence of stress, then it's likely you will wake up.
Very often, fatigue can be seen in people who have too much cortisol as well as those who have less than normal amounts of the hormone. Importantly, other hormonal problems, such as thyroid or pituitary problems, could lead to fatigue.
Cortisol belly fat, or visceral fat, is often associated with high stress levels. When the body is under chronic stress, it produces an excess of the hormone cortisol, which can lead to fat accumulation, particularly around the abdominal area.
High cortisol levels can also cause inflammation of your digestive tract and throw off the balance between the beneficial and harmful bacteria that live in your digestive tract. Stress can also affect the muscles of your intestines, which prevents your bowels from filtering out harmful gut bacteria.
In general, they'll be higher in the morning, peaking about 30 to 45 minutes after waking up. The early morning peak is part of what helps you wake up and it's known as the cortisol awakening response (CAR). Cortisol levels will then gradually decrease as the day goes on, hitting their lowest at around midnight.
“Eating foods such as processed meats, high sugar foods, caffeine and alcohol, which provide little nutritional value, have been associated with more psychiatric symptoms and can increase cortisol levels—our primary hormone responsible for stress,” she said.
Take deep breaths. Several studies reveal the benefits of deep-breathing exercises for at least five minutes, three to five times a day. Research shows that it helps to lower cortisol levels, ease anxiety and depression, and improve memory. To get started, try using a deep-breathing app like Insight Timer or Calm.
Remember magnesium will help lower cortisol, if you do not have adequate levels of magnesium your body cannot relax and remove excess cortisol.
Research suggests these herbs and natural supplements might lower stress, anxiety and/or cortisol levels: Ashwagandha. Rhodiola. Lemon balm.
There is, in fact, a chemical reason why you get more stressed, as when you're even mildly dehydrated cortisol levels in the body increase. Cortisol production is triggered by the stress response. And one way to balance these chemicals in your brain? Drink more water.
A cortisol test often uses a sample of blood drawn at a lab. But the test may also be done on urine or saliva collected at home. Normally, cortisol levels vary during the day, so your provider may order more than one type of test to get more information about your cortisol levels.
Yes, cortisol can be lowered naturally through positive lifestyle changes, specifically healthy sleep hygiene and stress reduction techniques.
