How To Reduce Cortisol At Night

Cushings Syndrome Or Cushings Disease

STOP Urinating Too Often! Tips That Actually Work |Diabetic or Not|

Cushings syndrome is the chronic overproduction of cortisol.

The most common cause of Cushings syndrome is the long-term, high-dosage use of corticosteroid medications, such as prednisone.

Injectable steroids for the treatment of back or joint pain can also cause Cushings syndrome if used in high doses over a long period of time.

Cushings disease isnt the same as Cushings syndrome.

With Cushings disease, elevated cortisol levels are caused by a tumor in the pituitary gland. This tumor causes the gland to create a high level of ACTH. This hormone then instructs your body to produce more cortisol than it needs.

The Role Of Cortisol And Sleep In Memory And Learning

Sleep plays an important role in our memory. During sleep, all the memories and knowledge we acquired while awake consolidate that is, the information labeled as important gets strengthened and the unimportant memories weaken. Memories and emotions get connected and arranged while you enjoy your shuteye and cortisol can help you in the process.

A group of scientists wanted to see whether cortisol thats present in the system at the time of learning affects memory. As it turned out, people who took some cortisol prior to learning and then went to sleep had much better chances of keeping those memories than those who didnt take any cortisol. Cortisol seemed to tag memories, especially if they were related to emotions. This tag helped the brain retain those memories.

Reduce Your Sugar Intake

You should avoid foods that have been heavily processed and pumped full of added chemicals and sugars if you’re looking for how to lower your cortisol levels. “One way to combat high cortisol levels, stress, and weight gain is to reduce simple sugars,” says Balk. The main foods that fall under this high-sugar category include:

While these sugary goodies might give you a temporary jolt of energy Balk suggests focusing on other sources of energy. “As your body still needs to receive sugar to fuel itself, focus on having complex carbohydrates rather than simple sugars.” Jim White RD, ACSM, and the owner of Jim White Fitness and Nutrition Studios adds that fiber-rich foods, protein, and healthy fats will also help keep your cortisol levels within the normal range.

Foods to combat stress and lower cortisol include:

  • starchy vegetables

Exercise In The Morning

Exercise does cause an increase in cortisol, and that’s actually a good thing in the morning, because that’s when we want our cortisol levels to be the highest. Then what’s going to happen the rest of the day is that the levels are going to naturally lower. And I know what you’re thinking: Kelly, I work full-time. How am I going to exercise in the morning?? Well, it doesn’t have to be a full-blown hour workout. You can simply walk around the block a couple times for 15 minutes and that’s all you need to get that cortisol increase. Keep it simple!

Exercise But Not Too Much

Pin on Health

Depending on the intensity of exercise, it can increase or decrease cortisol.

Intense exercise increases cortisol shortly afterward but will decrease a few hours later. This short-term increase helps coordinate growth of the body to meet the challenge. Additionally, the size of the cortisol response lessens with routine training .

Regular exercise has been shown in numerous studies to help improve sleep quality, reduce stress, and improve overall health, which can help lower cortisol over time .

Interestingly, regular exercise has also been associated with greater resilience to acute stress and may lower negative health effects associated with stress, such as high cortisol .

That said, overdoing it can have the opposite effect. Therefore, aim for around 150200 minutes of mostly low- to moderate-intensity exercise each week and allow yourself time to rest between workouts.


Exercising regularly can help you better manage stress and promote good health, which may help lower cortisol levels. That said, avoid overdoing it and aim for around 150200 minutes of low- to moderate- intensity exercise each week.

Symptoms Of High Cortisol Levels

According to research done by the Genetics Learning Science Center, the long-term danger of having high cortisol is that it activates the fight-or-flight response, which temporarily shuts down normal reproductive, digestive and immune functions. The body targets these systems for shutdown because it doesnt need them for immediate survival.

Sensory nerve cells pass the perception of a threat, or stress, from the environment to the hypothalamus in the brain. This signals the pituitary and primary adrenal glands to produce more cortisol. If this cycle goes on for too long, someone becomes more susceptible to all sorts of illnesses, infections and hormonal problems.

Some clues that may signal youre living with high cortisol levels include:

  • weight gain, especially around the abdomen/stomach
  • a puffy, flushed face
  • higher susceptibility to infections

Proven Ways To Lower Cortisol Naturally

  • The best ways to lower cortisol include practicing relaxation techniques, improving your diet, getting enough sleep, and caring for a pet.
  • You can also relieve stress by dedicating time to activities that promote happiness, such as building a social support network, spending time outside, exercising, or trying to make yourself laugh.

Cortisol is a naturally occurring hormone, often called the stress hormone, that plays a key role in your body’s stress response. It is also known as the “fight or flight” hormone, helping you manage stressful or dangerous situations.

When your brain perceives a threat, like a car suddenly stopping in front of you on the freeway or an unexpected noise in your house, it sends a signal to your adrenal glands to release a surge of hormones including cortisol and adrenaline to tell you to escape or prepare for conflict. This release of hormones can cause your heart rate to increase, your breathing to quicken, and your muscles to tense.

Finding healthy ways to deal with stress can help lower cortisol levels and regulate your body’s stress response. Here’s five ways to do it.

Causes Of High Cortisol Levels

Wondering what underlying conditions could be contributing to your high cortisol levels? Cortisol tends to go up as perceived stress goes up, so anything that triggers a negative mind states things like anxiety, worry, anger or frustration contributes to high cortisol levels. Medication use, inflammation, poor sleep and a poor diet can also trigger high cortisol levels by altering hormonal balances and negatively affecting the immune system.

Corticosteroid medications like hydrocortisone, prednisone pills or other medications used to treat inflammatory-related diseases or symptoms are common causes of high cortisol levels. Aside from corticosteroids, other major factors contributing to higher than usual cortisol production include:

  • recent surgery, illness, injury or whole-body infections

Art Music Or Another Creative Activity

Want an excuse to make a mess or turn up your favorite music? A 2015 study that compared participants cortisol levels before and after 45 minutes of art-making recorded improvements occurred in three-fourths of them.

The participants in this study worked with paper, pens, and modeling clay, but I wouldnt worry too much about which type of art you focus on. Music, photography, model-building, wood carving, writingjust do something creative. Interestingly, the strategy was especially effective in younger people, so if youre a parent who struggles with helping a child relax, you may want to try this as a way of rerouting their energy.

The Cortisol Rhythm And Sleep

Like nearly all hormones in the human body, cortisol has a daily, 24-hour rhythm. For most bio types, cortisol levels are at their highest in the morning, usually around 9 a.m. Cortisol begins to rise gradually in the second half of a nights sleep. The hormone begins a more rapid rise around the time youre waking up before peaking at about 9. From that point on, cortisol makes a gradual decline throughout the day, reaching its lowest levels around midnight. The activity of the HPA axis, which produces cortisol, reduces to its lowest levels in the evenings, right around your bedtime. In this way, cortisol plays a critical role in sleep-wake cycles: stimulating wakefulness in the morning, continuing to support alertness throughout the day while gradually dropping to allow the bodys own internal sleep drive and other hormonesincluding adenosine and melatoninto rise, and help bring about sleep.

This evening-low, morning-high daily cortisol rhythm is true for most chronotypes: Lions, Bears and Wolves. In Dolphins, however, the cortisol rhythm is inverted. Dolphins have cortisol on the rise at night and reaching its lowest levels in the morning. This inverted cortisol rhythm contributes to the difficulty falling asleep, restless and light sleep, groggy mornings and daytime fatigue that is so common among Dolphin chronotypes.

Poor sleep itself also can increase cortisol production and dysfunction of activity along the HPA axis. Research shows that cortisol can be elevated by:

Main Causes Of Waking Up At 3 Am Every Night

There are many possible causes of SMI as it relates to adrenal fatigue. But first, it is important to determine if there is a structural cause of the problem. Lung and airway obstructions can potentially cause waking up at 3 AM every night, disrupted sleep, and a doctor should first rule out any problems such as obstructive sleep apnea.

Once other causes have been ruled out, SMI usually arises either from one of a few dysregulation: neurotransmitter, hormonal, autonomic, or metabolic. The first cause is due to a disruption in the biological, circadian rhythms, caused by imbalanced levels of neurotransmitters such as GABA, serotonin, etc. Cortisol dysregulation, and elevation, at night is a possible hormonal cause of SMI. Cortisol is typically highest in the morning and decreases as the day goes on, with lowest levels at night. Cortisol levels then rise steadily toward the end of the sleep cycle, causing a person to wake up. During sleep, cortisol levels need to remain low, or the person is likely to wake up. With AFS, cortisol levels can start to increase at night, often times waking you up.

How Does My Body Control Cortisol Levels

Your body has an elaborate system to regulate your cortisol levels.

Your hypothalamus, a small area of your brain involved in hormonal regulation, and your pituitary gland, a tiny gland located below your brain, regulate the production of cortisol in your adrenal glands. When the levels of cortisol in your blood fall, your hypothalamus releases corticotropin-releasing hormone , which directs your pituitary gland to produce adrenocorticotropic hormone . ACTH then stimulates your adrenal glands to produce and release cortisol.

In order to have optimal levels of cortisol in your body, your hypothalamus, pituitary gland and adrenal glands must all be functioning properly.

Is Cortisol A Stress Hormone

Cortisol is widely known as the stress hormone. However, it has many important effects and functions throughout your body aside from regulating your bodys stress response.

Its also important to remember that, biologically speaking, there are multiple different kinds of stress, including:

  • Acute stress: Acute stress happens when youre in sudden danger within a short period of time. For example, barely avoiding a car accident or being chased by an animal are situations that cause acute stress.
  • Chronic stress: Chronic stress happens when you experience ongoing situations that cause frustration or anxiety. For example, having a difficult or frustrating job or having a chronic illness can cause chronic stress.
  • Traumatic stress: Traumatic stress happens when you experience a life-threatening event that induces fear and a feeling of helplessness. For example, experiencing an extreme weather event, such as a tornado, or experiencing war or sexual assault can cause traumatic stress. In some cases, these events can lead to post-traumatic stress disorder .

Your body releases cortisol when you experience any of these types of stress.

How Is Cortisol Measured

Cortisol is measured using urine, saliva, and blood tests. Below is a breakdown of each kind of test.

Cortisol urine test: This kind of test measures free cortisol in your urine three to four times throughout the day. Urinary free cortisol tests, like the Everlywell at-home Sleep & Stress Test, are useful for checking how your cortisol levels change over a 24-hour period and can help provide insight into sleep problems, stressors, and more.

Cortisol saliva test: This test also measures the amount of free cortisol in the body, but through a saliva sample. Late-night salivary cortisolâ âthe measurement of cortisol in a saliva sample collected late at nightâ âis a reliable way to screen for Cushing syndrome.

Cortisol blood test: Blood tests measure either free cortisol or total cortisol. Blood total cortisol tests are helpful for diagnosing certain conditions, such as adrenal insufficiency in patients with critical illnesses like severe pneumonia and respiratory distress syndrome.
