Cold Submersion Therapy or Cold Water Immersion (CWI) is an ancient hydrotherapy treatment. It relieves many ailments and chronic symptoms. People suffering from immune system or mood disorders, have trouble sleeping or have increased stress levels can benefit from this type of therapy. This form of hydrotherapy is similar to aquatic therapy, pool therapy, or balneotherapy. The use of water in various forms and at various temperatures produces amazing effects on the human body.

In Activating the Vagus Nerve: Part 1 – Breathe!, we explored the positive effects that breathwork has on our Vagus Nerve. How we breath affects our autonomic nervous system – which has two branches, sympathetic (fight or flight) and parasympathetic (rest and digest). You can think of the sympathetic as the gas pedal on your system and the parasympathetic as the brakes. Let’s now dive deeper into how we can manipulate the nervous system and make it stronger by introducing cold water immersion (CWI) therapy while we are breathing.

“Cold water? What the … ?!” You might exclaim, especially if you are living in a cold climate like Calgary, Alberta.

Taking actionable steps like CWI therapy can help reduce stress levels. CWI is an ancient therapy used to relieve many ailments. People suffering from immune system or mood disorders, having trouble sleeping, or increasing stress levels can benefit from this type of therapy. Here we outline some reasons why CWI is so good for you. It enhances your immune function, boosts your metabolism, elevates your mood, and builds endurance.

Reasons to try CWI

Enhance Your Immune Function

Cold Submersion Therapy stimulates immune function. It does this by stimulating the white blood cells. They then provoke the white blood cells to attack and destroy toxic substances in the lymph fluid. The cold water positively affects the lymphatic system, affecting the immune system by flushing waste and toxins.

Boost Your Metabolism

Cold Submersion Therapy helps to boost your metabolism, which can assist with weight loss efforts. This is not to be substituted for a healthy diet and regular exercise. This practice makes your body work harder to keep you warm, which inadvertently burns calories. It also affects the type of fat the body produces. According to a study done in 2009, brown fat (BAT), or good fat, mobilizes when your body becomes exposed to frigid temperatures. It works to keep us warm, thus eliminating white fat, which is the fat that sits around your thighs and waist.

Improve Sleep, Reduce Stress, & Elevate Mood

When we sleep, our bodies heal, so it is vital to get adequate restful sleep. CWI reduces muscle soreness and pain, which allows you to sleep more soundly. Quality sleep will, therefore, reduce stress levels and elevate your overall mood.

Build Endurance & Resilience

The thought of submerging your body in cold water makes most people cringe, but it is suitable for your body and your mind! It is a good practice in mental strength, endurance, and resilience which requires you to break out of your comfort zone. I learned that cold never stops being hard. It never gets easier, but your mind has become more resilient and robust. Immersing your entire body in ice water trains your brain to control your responses to stress, pain, and anxiety, instead of allowing your emotions to overwhelm you. Try reframing your thoughts with mindful breath and action by breathing through sensations and feelings that arise. CWI will allow your body and mind to work through a state of stress and enter a state of calm. Don’t forget to breathe, as this is so crucial. When our breathing is full and deep, the diaphragm moves through its entire range downward to massage the internal organs and tissues below it and then moves upward to massage the heart. Training the body to control the breath and negative mind chatter can be a total game-changer for anxiety and depression.

If cold water immersion still isn’t seeming like your thing, try ending your showers with cooler water temperatures. You can start slowly and build up to longer stints of colder temperatures. Breath through the discomfort and find a motto to help build your resilience, such as “I am more than my thoughts,” or “I choose to step into mindful, peaceful action”, and “I am stepping away from fear.”

The cold never stops being cold but taking actionable steps that you can implement into your daily/weekly routine will guide you towards taking back control over your health by increasing resilience in your mind and body. How powerful is that! Challenge yourself today by trying the Wim Hoff method of Cold Submersion Therapy along with deep diaphragmatic breathing for your overall health. Take the plunge!

Why are DHEA & Testosterone Important?

Testosterone is a male hormone, right? True, but females need it just as much as males do, just in smaller amounts. Not only is necessary for a healthy libido and sexual satisfaction, but it is also essential for bone health, brain health, muscle health, and heart health. It needs to be in balance with the other female hormones, estrogen, and progesterone (sex steroids), thyroid hormones, as well as our major stress hormone, cortisol, in order to function optimally. The Androgen DHEA is a feel-good hormone. It gives one a feeling of well being, libido, good sleep, muscle strength, and exercise tolerance.

What are the common symptoms of DHEA deficiency?

Common symptoms of DHEA deficiency include reduced sex drive, reduced sexual sensitivity, difficulty achieving orgasm, painful intercourse, low mood and excessive anxiety, poor coping ability, reduced muscle tone and strength, joint pain, back pain, dry skin, poor memory or concentration and urinary incontinence. The symptoms can overlap with hormonal and other medical conditions. Thus, androgen deficiency often goes under-diagnosed and is not often thought to be relevant in females.

Cortisol Steal

So where does it all go wrong and why are we seeing so many women, young and old, with deficiency these days? Cortisol steal. This is exactly what it sounds like. Cortisol is stealing the substrates that our sex steroids and DHEA need to be formed because it is being produced in excess. DHEA becomes depleted and because this is upstream from testosterone (and estrogen), these downstream hormones also become depleted. So it’s the stressed women that get more hormonal issues. It is not the hormones’ fault. They are just responding appropriately to other imbalances in the body. Why would you need to reproduce or have sex for that matter, if you are running away from a lion?

Stress and Hormones

The body interprets internal and external stress as the same thing. It doesn’t know the difference between having a fight with someone vs candida overgrowth in the gut, for example. It responds by releasing cortisol and other stress hormones and neurotransmitters from the adrenal glands. When cortisol is produced in excess, the hypothalamus in the brain perceives a threat. It switches off signals to the adrenals and cortisol is no longer produced. Alongside this, high cortisol triggers DHEA release, which tries to balance the high cortisol. With DHEA and cortisol levels low, the patient experiences stage 3 adrenal fatigue. The new term for this is HPA axis dysfunction/ dysregulation.

Replacing DHEA and Testosterone in Women

DHEA and testosterone can be replaced alone, or alongside each other in women. It should be ensured that the other female hormones are also optimal. In our practice, we prescribe bioidentical hormones, which are hormones that behave in an exact way as our own hormones. They are still laboratory-made but are chemically identical to our hormones. The bad rap that hormone replacement has is from synthetic hormones, which confuse our hormonal systems – like putting the wrong key into a lock. Testosterone is most often prescribed topically, or in certain cases intramuscularly/ subcutaneous. DHEA is most often prescribed sublingually or by mouth, but can also be given topically.

The key to safe hormone replacement is testing your levels (24 hour urine hormone is the best test for this, but blood levels can be used when resources are limited). Once on the treatment, levels should be monitored by an experienced health care professional in order to find the dose that is right for you. This can vary tremendously between women, depending on genetics, underlying factors that caused the hormone deficit and lifestyle (a very active woman requires more DHEA or testosterone, often). You can find your optimum dose by looking at your levels alongside your symptoms.

What else can you do to improve your levels besides taking hormones?

Hormone replacement is not the only answer but in every case, should be done alongside root cause treatment and lifestyle changes. Hormone replacement does not fix the adrenals and other hormones. It is just another patch if done alone. Some women even feel worse on hormones, which tells us we need to work on these root causes.

Other Lifestyle Improvements

So what can you do to help these hormones in your day to day life? Your overall aim is to decrease inflammation and stress on the HPA axis.

Diet

An anti-inflammatory diet is a good place to start. Many hormone disturbances start in the gut, because of a constant onslaught of foods that increase inflammation, upregulate our immune system, change our microbiome, and impact our gut-brain connection. Sugar, carbohydrates, and dairy are big contributors to poor hormone health.

Exercise

Make sure you are getting exercise that is appropriate for your condition. Don’t run a marathon when your adrenals are shot.

Sleep

Make sure you get at least 7-8 hours of sleep each night. Good sleep hygiene is essential and your health care professional may recommend supplements and medications for this.

Stress Management

Make sure you are identifying and managing stress – we cannot always change our stressful circumstances but we can change how we perceive them and what we do every day to find our calm.

One vital component of your health that you might be neglecting is precious sleep. It is absolutely critical for both your short and long term health, and in our modern society, millions of people don’t get sufficient sleep. It’s well known that the ideal amount for optimal health is eight hours. Truthfully, the amount needed varies from person to person. Everybody is different and individual factors like age, overall health, stress level, and activity level can heavily influence how much you actually need.

Sleep Quality & Circadian Rhythm

When it comes to sleep, quality is just as, if not more, important than quantity. Spending nine hours tossing and turning without ever entering deep sleep will not leave you refreshed and ready to go in the morning. What you need is an adequate amount of REM (rapid eye movement) each night. This is one of the deepest sleep phases where you experience your most vivid dreams.

Circadian rhythm or individual internal clock controls the sleep cycle. They developed in our ancestors in response to the natural day/night and seasonal cycles of the earth. It’s the reason why humans aren’t innately nocturnal and tend to be active during the day. These modern times can throw off your circadian rhythm. Artificial lighting, days spent working indoors, an unnatural diet, and night shift work may all contribute to a disordered internal clock. A variety of consequences – ranging from mild fatigue and depression to seasonal affective disorder (SAD) to even worse – can result from living with an out of balance circadian rhythm (1).

Even breaking your sleep cycle by frequently getting up to urinate during the night may cause depression (2). However, there are several steps you can take to get high-quality sleep and maintain a balanced circadian rhythm.

Tip 1: Be Careful with Caffeine

Chances are that you consume at least some caffeine almost every day. While coffee is the most obvious culprit, caffeine is also present in many sodas, teas, and chocolate products. It’s no big deal to enjoy a morning java, but try to limit your intake. Even more importantly, avoid consuming caffeine past about mid-morning. The effects of caffeine can last seven hours or more, so it’s important that it’s all out of your system by bedtime. In fact, a 2014 study reinforced what we pretty much already knew, caffeine can significantly disturb your sleep (3).

Tip 2: Eat Dinner About 4 Hours Before Bed

You certainly don’t have to grab the early bird buffet special at 4 pm, but neither should you eat dinner at 10 pm and hit the sack one hour later. That’s because your body breaks down carbohydrates, or sugars, over time. You don’t need a sugar spike for energy while you’re sleeping, and an increase in blood glucose can actually cause you to have fitful, shallow sleep. Your best bet is to eat a dinner containing complex carbohydrates, like starch, about four hours before going to sleep. This will allow your body time to breakdown the carbs, giving you adequate energy for your remaining time awake while avoiding the middle of the night glucose spike.

Don’t Sleep at the Screen!

Tip 3: Limit Your Screen Time

If you fall asleep with a laptop or smartphone, you’re certainly not alone. Still, this type of screen time is a habit worth breaking. Computer monitors, televisions, and phone screens give off blue light, which interferes with the action of melatonin. Melatonin is a hormone that promotes sleepiness and helps you actually get to sleep. Blue light tricks your body into believing it’s still daylight outside and not yet time for sleep. Remember, your body’s systems haven’t caught up with modern technology. Do yourself a favour by discontinuing screen time at least two hours before bed.

Tip 4: Make Your Bedroom Sleep Hygienic

Just like you practice oral hygiene by brushing your teeth before bed, you need to observe sleep hygiene for a good night’s sleep. This means dedicating your bedroom to sleep and limiting distractions. Keep it nice and dark, as studies have shown a connection between melatonin levels and more light exposure, and don’t let the temperature get higher than about 21 degrees C– not a problem during the Albertan winters (4). Finally, try to insulate yourself from any unnecessary noise so that you’re not prematurely roused from restful sleep.

Tip 5: See Your Functional Medicine Doctor

Dr. Lynne Murfin treats all sorts of sleep disorders and can help discover the cause of your issue. Her training and experience are extensive. While there are many different things that can upset your circadian rhythm, there are also many treatments available, many of them natural.

For example, the stress response (“fight or flight”) has a huge effect on sleep quality, but this can be addressed in a variety of ways. Mind-body exercises guided by Dr. Murfin or her lifestyle educator can help reduce the stress and anxiety, and supplements.

Supplements for Sleep

Taking supplements for sleep is another option your functional medicine doctor may recommend. Supplemental B12 taken upon arising in the mornings may “reset” your stress response mechanism. In fact, vitamin B12 shows to have an effect on stress hormones in lab rats (5).

Another supplement that has shown promising results is valproic acid. This compound, in low doses, demonstrated an ability to reduce depression and restore circadian rhythm in a patient with an associated disorder (6).

Hormones for Sleep

Additionally, the use of hormones under Dr. Murfin’s direction can aid you in getting consistent, good sleep. If you’re not producing enough melatonin, small doses of this hormone could help in reducing your sleep latency, or the time it takes you to fall asleep. Melatonin is vital to the circadian rhythm. A study published in the journal Sleep Science even showed a correlation between low melatonin and the development of dementia in elderly patients (7).

Other substances that can have a positive effect include serotonin, gamma-amino butyric acid (GABA), and the female sex hormone progesterone. These compounds all frequently become imbalanced by a number of factors and need correction. For example, progesterone may protect against developing obstructive sleep apnea, a common sleep disorder (8).

GABA is a neurotransmitter involved in sleep maintenance. Low amounts of GABA have an association with insomnia, but fortunately, GABA supplements are available (11). Progesterone levels may drop during menopause, but research has shown that hormone therapy can result in better sleep (9).

Serotonin also plays its part in sleep, specifically maintenance. This neurotransmitter makes sure that you stay asleep long enough to truly rest. Serotonin has long been recognized to have a role in depression, with low levels contributing to depressive symptoms. It’s now known that serotonin can also directly affect the adrenal glands, crucial components in the stress response (10).

Controlling your stress response is a vital part of getting good sleep.

Consult a Qualified Physician

All neurotransmitters and hormonal supplements should be taken under the close monitoring of a qualified physician. Dr. Murfin can assist you in getting the best sleep possible. Lifestyle changes, nutrition support, and supplements may all contain the answers to your difficulties. Just remember – the road to good, and continued health – starts with you.
