Cortisol and Sleep (HOW DOES CORTISOL AFFECT SLEEP?)

Can sleep apnea affect cortisol levels. Morning cortisol levels and glucose metabolism parameters in moderate and severe obstructive sleep apnea patients. Hpa axis hyperactivity can lead to fragmentation of sleep decreased slow wave. Many people with sleep apnea go undiagnosed for years.

However if you feel that cortisol may be the culprit behind your sleepless nights here s what you can to naturally lower your cortisol levels. Doni 11 th december 2014. Observed lower vitamin d levels in osa patients.

You can start by eating foods that are sleep. They also suggested a 24 hour cortisol profile instead of measuring levels at a single point in time which did not allow studying the precise alterations and dynamics of cortisol levels reference. Doni author of the stress remedy discusses how weight gain and sleep apnea can disrupt your sleep and offers advice on how to address both issues.

You can see how sleep apnea can lead to adrenal fatigue. The pathophysiology of obstructive sleep apnea osa has been associated with dysregulation of the hypothalamic pituitary adrenal hpa axis. Your adrenal glands are working overtime when you sleep secreting high levels of the hormones epinephrine aldosterone and cortisol.

In fact many health issues related to high cortisol levels mirror the health issues related to obstructive sleep. Obstructive sleep apnea may affect bone also by reducing vitamin d levels. As seen in obstructive sleep apnea.

The Role Of Diet Exercise And Cytokine Antagonists In The Management Of Sleep Apnea

Even modest weight loss results in a clinically significant improvement of metabolic complications and cardiovascular risk profile of obesity which are closely associated with OSA . Weight loss in surgically treated morbidly obese patients improved the symptoms of OSA and reduced AHI . In patients with OSA and severe visceral obesity treatment with intragastric balloon reduced the number of apneic episodes during sleep and the daytime symptoms of OSA, even with a relatively modest level of weight loss and despite the fact the patients still remained affected by severe obesity after treatment . The improvements of OSA observed after a modest weight loss may be a part of the better responsiveness of visceral than subcutaneous fat to caloric restriction .

In a recent study in 1104 men and women enrolled in the Wisconsin Sleep Cohort Study, â¥7 h of exercise per week compared to 0 h of exercise per week was associated with a significant reduction of AHI independent of BMI, age, gender, and other covariates . According to our unpublished data, among sleep apneics regular exercise is the strongest predictor of excessive daytime sleepiness in men, while depression, metabolic syndrome and AHI are the strongest predictors of EDS in women. Exercise improves insulin resistance and visceral adiposity independently of body weight and this can be the mechanism positively affecting nighttime and daytime symptoms of OSA.

What Is Cortisol You Ask

Scientifically speaking, cortisol is a glucocorticoid produced in the adrenal glands located at the top of your kidneys. The hypothalamic-pituitary-adrenal axis regulates your body’s cortisol secretion .

The primary roles of cortisol include:

  • Promoting alertness when your body’s fight-or-flight response is activated by a stressor
  • Influencing your sleep-wake cycle to help you meet your sleep need

We will go into the specifics in the following sections. All you need to know now is that cortisol has its own circadian rhythm. When your cortisol rhythm is properly functioning, your body produces this stress hormone in the right amounts at the right times. This is beneficial and necessary for your overall health. But too much cortisol over prolonged periods triggers a never-ending cycle of elevated cortisol levels and sleep loss that sets you up for various health problems, as you will see.

Treating Excess Of One Hormone Shows Promise For Decreasing The Risk Of Obstructive Sleep Apnea

    Treating the overproduction of one hormone may be a way to help a subset of the millions of Americans who suffer from obstructive sleep apnea, according to a new study.

    A UCSF study has found that treating patients for an excess of the hormone aldosterone relieved their obstructive sleep apnea, giving a new avenue for treating a subset of the people who have the disorder.

    People with obstructive sleep apnea stop breathing for short periods while they are sleeping, which leads to a poor nights sleep and debilitating fatigue during the day. Most people with the condition need to use dental devices or CPAP machines to sleep at night.

    But researchers at UC San Francisco have found that treating a condition in the adrenal glands causing an excess of aldosterone, a hormone that maintains electrolyte balance and blood pressure, may be an effective way to help people reduce the risk of obstructive sleep apnea.

    UCSF endocrine surgeons Insoo Suh, MD, and Quan-Yang Duh, MD, didnt set out to study sleep apnea. Suh and Duh specialize in the treatment of primary aldosteronism, a disease in which one or both of the adrenal glands overproduce the hormone aldosterone, and were looking into the question of whether this hormone plays a role in obesity. Obesity is a major factor in obstructive sleep apnea, which meant that many of the surgeons patients were living with that condition as well.

    What Happens To Your Sleep If Cortisol Levels Are High

    The problem is if you’re stressed all day and your cortisol levels are high, then when you go to bed, you will still have higher than normal levels of cortisol in your system. Then, after midnight, when the cortisol levels rise again, your levels will be extremely high and youll feel wired and have difficulties staying asleep. Hello, 3:00 AM wake-up!

    How The Ans And The Hpa Axis Join Forces In Stressful Situations

    In the presence of a stressor, the fight-or-flight response is activated, as the PNS slides into submission while the SNS and HPA axis take over. Within the ANS, the hormone adrenaline and the neurotransmitter noradrenaline are released. This is why you feel like you are in a heightened mode of alertness. It also explains some of the physiological reactions you experience, such as a faster heart rate.

    At the same time, the HPA axis goes into work mode to bring about the following changes:

    • The paraventricular nucleus secretes corticotropin-releasing hormone .
    • CRH binds to the CRH receptors in the anterior pituitary gland to release adrenocorticotropic hormone into the bloodstream.
    • ACTH then signals the adrenal cortex to produce and discharge cortisol.

    As mentioned earlier, the HPA axis interacts with the ANS during times of stress. This interaction is primarily seen in how CRH activates the release of NE during the fight-or-flight response. NE then stimulates the HPA axis to produce more CRF, resulting in a positive feedback loop that amplifies cortisol levels within your body.

    Can Sleep Raise Or Lower Glucose Levels

    Although it sounds contradictory, sleep can both raise and lower glucose levels. Our bodies experience a cycle of changes every daycalled a circadian rhythmwhich naturally raises blood sugar levels at night and when a person sleeps. These natural blood sugar elevations are not a cause for concern.

    Restorative sleep might also lower unhealthy blood sugar levels by promoting healthy systems. levels. Even partial sleep deprivation over one night increases insulin resistance, which can in turn increase blood sugar levels. As a result, a lack of sleep has been associated with diabetes, a blood sugar disorder.

    More research is needed to better understand the connection between sleep and blood sugar. So far, the following factors have been found to influence the relationship between sleep and blood sugar levels:

    Waking Up And Cortisol The Cortisol Awakening Response

    DO THIS TO LOWER CORTISOL | CORTISOL AND SLEEP CONNECTION

    For the majority of people, cortisol levels increase sharply by about 50% within an hour of waking up, peaking about 30 minutes after waking. Some research suggests that the cortisol awakening response is genetically set for each of us.

    Some factors can increase cortisol in the morning even more. For example, waking up in the light causes a higher cortisol awakening response than waking up in the darkness as well as waking up earlier than usual. The cortisol response to awakening is higher on a working day than on a day off.

    Science is still looking for clear answers to why exactly most of us have the CAR but one suggestion says that it could be a way for our body to prepare us for the expected stress and high demands during the day.

    How To Improve Cortisol Levels Naturally

    Keeping cortisol levels in checkand HPA axis activity from ramping up too highcan contribute to healthier sleep. Of course, sleeping bettermaking enough time for nightly sleep, adhering to a consistent sleep routine, practicing other fundamentals of sleep hygieneis one way to lower cortisol. Here are others:

    Keep Cortisol And Sleep Loss In Check

    While it’s easy to lose yourself in the nightmarish labyrinth of cortisol overrun and sleep loss, proper sleep hygiene helps you emerge from the maze by keeping your sleep debt low and your circadian rhythm running smoothly. The reason being, low sleep debt and circadian alignment promote a well-functioning homeostatic process that maintains optimal cortisol levels in your body. With cortisol working optimally, your sleep-wake cycle is steered back on track.

    Use our step-by-step Sleep Guide to learn how you can perfect your sleep hygiene.

    Just as important for cortisol management is making a conscious effort to minimize your stress levels, as they are the trigger point for chronic cortisol secretion. One effective way to do that is to schedule an evening wind-down routine in the 1-2 hours before bed.

    Letting go of the day’s stressors gives your body a chance to switch from the SNS to the PNS. Remember that the PNS effectively reverses the effects of high cortisol levels during stressful situations to return your body to homeostasis. This switch is key to helping your body move between the two systems without being stuck on high alert all the time. Activating your PNS during your wind-down helps you slide into sleep more effortlessly.

    Below, we detail some simple yet effective stress management techniques you can incorporate into your wind-down routine:

    Sleep And Cortisol Levels Under Stress

    True to its name as a stress hormone, cortisol levels become elevated in times of stress. When you are stressed out, the heightened cortisol serves to increase brain activity during sleep, which reduces the amount of time you spend in slow-wave sleep, causing lighter sleep, and waking up frequently throughout the night.

    Cortisol And Sleep Cycles

    Stress and Cortisol â Walking Off Pounds

    Sleep isnt a steady state. Your body goes through various stages of sleep each night.

    Non-REM sleep has 3 stages.

    • Stage 1. This stage lasts a few minutes as you drift from being awake to being asleep.
    • Stage 2. Your bodys systems relax further, your core temperature drops, and your brain waves are slower. You spend about 50 percent of your sleep cycle in this phase.
    • Stage 3. This phase is also known as slow wave sleep. Its when your heart rate, breathing, and brainwaves are slowest.

    REM sleep is the part of your sleep cycle when you have vivid dreams.

    A sleep cycle lasts about 90 minutes, and during that time you move through these four stages of sleep.

    Most of your deeper slow wave sleep happens in the first half of the night, while REM sleep happens more during the second half of the night.

    Researchers have found that when the HPA axis is overly active, it can disrupt your sleep cycles, causing:

    • fragmented sleep
    • insomnia
    • shortened overall sleep time

    Those sleep disturbances can wreak further havoc on your HPA axis, distorting your bodys production of cortisol.

    Sleep Apnea And Continuous Positive Airway Pressure Treatment

    CPAP is the treatment of choice, especially in moderate to severe OSA, with proven efficacy on daytime sleepiness and high blood pressure . Randomized trials have shown benefit in severe OSA in subjective sleepiness, objective tests of sleepiness, quality of life, driving performance, and depression scores . On the other hand no benefits of therapy were observed in severe OSA if subjects were not sleepy . In mild to moderate disease, CPAP ameliorated only nighttime symptoms in all studies , whereas in most studies subjective sleepiness did not change .

    The effects of CPAP on the metabolic alterations associated with OSA have not been studied systematically, and the results are inconsistent . No improvement in insulin sensitivity was observed in 9 studies. The beneficial effect confirmed in one study, was observed primarily in non-obese patients with OSA . Also, in non-obese patients with OSA, visceral fat decreased after 6 months of CPAP use, even without change in BMI .

    Inconsistent were also the results on the effects of CPAP on inflammation. A significant decrease in TNFa was reported after the use of CPAP . IL-6 increased in one study and decreased in another study after the use of CPAP .

    Studies to date have primarily evaluated short-term outcomes of CPAP use, typically 1 to 2 months, in both obese and non-obese patients with OSA.

    The Health Problems Created By Sleep Insufficiency

    First and foremost, you can think of cortisol-induced sleep loss in terms of:

    • Acute sleep debt, which is the amount of sleep you’ve missed out on in the past 14 days
    • Chronic sleep deprivation, which refers to restricted sleep over a prolonged period of several months or years

    In the short term, acute sleep debt downgrades every aspect of your life that matters, from your cognitive functioning to your immune system to your social relationships. Over time, acute sleep debt progresses to chronic sleep deprivation, in which a new host of health problems arrive, courtesy of your bodyâs persistently high cortisol levels. The long-term effects of sleep insufficiency are well-documented in scientific literature, particularly in the form of metabolic health issues such as:

    • Obesity
    • Type 2 diabetes
    • Heart disease

    As if the direct impacts of sleep loss itself aren’t distressing enough, you also have to contend with the additional health issues that too much cortisol instigates.

    Cortisol And Weight Gain

    In addition to the link between cortisol and sleep, there is a link between cortisol levels and weight gain. Many people stress-eat as a coping mechanism in tense times, which can cause weight gain. Chronic stress is known to boost hunger and therefore cause weight gain in the longer term as well.

    The relationship between cortisol and sleep and weight gain is most evident in times of sleep deprivation. Lack of sleep contributes to elevated cortisol levels, which causes the body to develop insulin resistance, an inability of the body to release insulin in response to heightened glucose levels.

    Insulin resistance, therefore, reflects the bodys failure to properly control blood glucose. It is a key component of both prediabetes and type 2 diabetes. Just one night of sleep deprivation can create conditions of insulin resistance equal to six months on a high-fat diet! Luckily, in the short term, insulin resistance created by sleep loss can be reversed by catching up on sleep.

    You may be wondering about how to lower cortisol levels and lose weight. Sleep seems to be a major player in reducing stress and, by association, cortisol. You can read more about the link between cortisol and weight loss, and how sleep can help you reach your weight loss goals, here.

    Should I Test My Cortisol Levels

    Sleep, Cortisol, & Belly Fat

    You may be tempted to pay for a cortisol test. Cortisol testing has now become a commercial enterprise, with companies offering mail-in testing based on salivary cortisol as well as urine and blood.

    You should speak to a doctor about obtaining cortisol testing to ensure that it is the proper choice for you. Many cortisol test companies work together with doctors offices to ensure that medical professionals can review and interpret your test results.
