Cold plunging has a huge significance in the quality of your sleep. Nowadays, more people are finding it hard to get a good night's sleep. According to a report from the National Council on Aging, there are about 30% of adult Americans have symptoms of insomnia which have a strong impact on their daily lives.
Now, is it okay to cold plunge before bed? Let's find out! A study titled, Effect of the Depth of Cold Water Immersion on Sleep Architecture and Recovery Among Well-Trained Male Endurance Runners, shows that runners who do cold plunge therapy after a workout had more slow-wave sleep during the first three hours, woke up less throughout the night, and experienced fewer limb movements while sleeping.
Cold Plunge for Enhanced Sleep
Cold plunging has some fascinating science behind its ability to enhance the quality of your sleep quality. When you immerse yourself in cold water, your body undergoes a natural temperature regulation process. Your blood vessels constrict, reducing blood flow to your extremities and redirecting it towards vital organs. This helps maintain your core body temperature and signals your brain that it’s time to rest, setting your body up for better relaxation and sleep.
Plus, cold water immersion (CWI) stimulates the release of endorphins, those feel-good chemicals that play a big role in reducing your stress and anxiety. With less stress weighing on your mind, it becomes much easier to unwind and drift off to sleep. The cold plunge also boosts circulation throughout your body, which improves oxygen delivery to various tissues. Enhanced circulation supports healthy sleep patterns and overall recovery.
Should You Cold Plunge Before Bed?
Melatonin is often referred to as the "sleep hormone," and its main job is to regulate your sleep cycle, telling your body when it’s time to wind down. Interestingly, taking a cold plunge before bed can support melatonin production by triggering your body’s natural response to cold stress. When you're exposed to cold water, your body releases norepinephrine, a hormone that can ultimately boost your melatonin levels.
So, by adding a cold plunge into your routine, you're not just cooling down, but you're also helping your body get into a better sleep rhythm. Whether you're looking to make your own cold plunge or find the most affordable cold plunge tub options, this practice can play a role in improving your sleep cycle.
Your Parasympathetic Nervous System
The parasympathetic nervous system, which controls many of your body's involuntary functions, can also benefit from cold water immersion. Ice baths stimulate what's called the "cold shock response" or "diving reflex," which helps activate this system. When you're immersed in cold water, particularly up to your neck, your body shifts into conservation mode, which helps maintain homeostasis.
Ice baths can prevent the drop in parasympathetic activity that often follows exercise, which has a direct connection to better sleep quality. Incorporating a cold plunge, whether you choose to buy one or make your own cold tank, could help maintain balance in your autonomic nervous system and enhance your overall well-being.
Slow-Wave Sleep
Slow-wave sleep, often called deep sleep, is a critical part of your sleep cycle because it's when your body experiences the deepest restoration. Taking an ice bath before bed has been shown to positively impact this crucial stage. By lowering your body temperature through cold immersion, you're helping your body enter this deep sleep phase more easily, and this can result in better sleep quality, improved recovery, and enhanced overall wellness.
The Mechanisms of Getting Better Sleep
In cold plunging, one of the key mechanisms at play is temperature regulation. When you expose yourself to cold water, your body kicks into its natural thermoregulatory response. Your blood vessels constrict, reducing blood flow to your extremities and redirecting it to your core organs. This shift not only helps maintain your core body temperature but also promotes relaxation, Which signals your brain that it's time to rest and wind down for the night.
Another benefit is the release of endorphins, those feel-good neurotransmitters that are responsible for reducing pain and boosting pleasure. A cold plunge can trigger this release, helping alleviate your stress and anxiety, which in turn makes it easier for your mind to relax before bed. This endorphin rush also helps you shake off the mental clutter of the day, allowing you to ease into a more peaceful state before sleep.
Plus, cold plunges improve circulation throughout the entire body. The shock of the cold water stimulates blood flow, enhancing oxygen delivery to tissues, including those that regulate sleep. Also, better circulation means your body is more efficient at promoting healthy sleep patterns, making cold plunging a powerful tool not just for physical recovery, but for unlocking better, deeper sleep.
Actor Rainn Wilson uses his Renu Therapy cold plunge tub to get a greater sense of well-being and have a good amount of dopamine throughout the day. He spends 2 minutes to 3 minutes doing cold water immersion and feels total relaxation.
How to Add Cold Plunging to Your Bedtime Routine
Starting your bedtime with contrast therapy, which is a combination of hot and cold temperature routine is a great way to get a good night's sleep. The warmth helps relax your muscles and gets your body ready for the sudden shift in temperature. This initial step can make the transition to cold water feel more manageable and less jarring.
Now, when doing a cold plunge, you must ease into it gradually. Start with lukewarm water and slowly decrease the temperature until it’s cold but still tolerable. This approach helps your body acclimate to the cold and reduces the shock of suddenly immersing yourself in icy water, making the experience more comfortable over time.
It’s also important to keep your cold plunges brief, especially before bed. Start with just 30 seconds and gradually increase the time as your tolerance to the cold improves. This ensures you get the benefits of cold exposure without over-stimulating your system.
