INCREASE ENERGY

SKYROCKET FOCUS, PRODUCTIVITY + ALIVENESS

Cold water immersion profoundly stimulates the metabolic system by boosting mitochondrial function to create more ATP. Activation of the sympathetic nervous system increases noradrenaline by 530% via the cold shock response. 

JOSEPH'S STORY

My experience with cold water immersion has been amazing on many levels, but especially for my energy and reduction in stress. Due to my job I work long hours in high stress environment and would have major energy crashes mid day and was a regular caffeine drinker to accommodate this. Since I started my cold water immersion with my Edge Tub, not only have I noticed a significant difference in my mood and ability to manage stress creating an overall calmness to me, but I have really noticed a difference in my energy levels. After starting my day with my edge tub I feel refreshed and energized through the entire day, not needing pick me ups. Thank you Edge Theory Labs for creating such a great product and helping bring wellness and good vibes to the masses!

BOOST METABOLISM

INCREASE VITALITY, LONGEVITY AND BURN FAT

Metabolic efficiency is one of the greatest indicators of longevity and health span. Cold water immersion has been shown to increase metabolic rate by up to 350%, strengthen mitochondrial function, and improve insulin sensitivity. Research also suggests that the activation of brown adipose tissue can help to put your body into a fat burning mode and subsequently reduce your waistline. 

BILLY'S STORY

I have been struggling with my weight between shift work and overtime not being able to find a balance and focus.  I got my Edge Theory Labs tub and began a daily practice of cold water immersion.  I started my day off with a dip and sometimes before I would head into work for a late shift.  My focus sharpened and created the edge I needed to find the balance to get back on track.  I went from 238 to 226 in just under 2 weeks.  Next stop 215

ENHANCE MENTAL HEALTH

REDUCE ANXIETY & STRESS, ELEVATE YOUR MOOD

The cold stimulus activates natural mood boosters like endorphins and dopamine by up to 250%, which can help boost feelings of positivity.  Furthermore, induction of cold shock protein RBM3 is known to protect against neurodegeneration, sharpen cognitive function, and promote neuroplasticity in humans.

FRED'S STORY

The cold saved my life. I was going through a very tough time mentally, dealing with imposter syndrome, insomnia, and panic. I was a full time Muay Thai fighter who retired and was sitting at a desk working in Tech for 10 hrs. Cold immersion played a huge role in calming my nervous system and giving me a platform to express all of my feelings. It's been 5 years since that time and I'm the strongest I've ever been still using the cold as a tool for self love, for healing, and to prepare me for whatever life has next.

DECREASE CHRONIC INFLAMMATION

FEEL STRONG RESILIENT & FREE

Chronic inflammation can lead to auto-immune disease and negative health outcomes. Cold water immersion may be helpful in reducing an overactive inflammatory immune response, decrease pain, and improve quality of life. 

CHRIS' STORY

Cold immersion has been a remarkable tool in my journey towards reducing inflammation, as it has consistently provided me successful healthy results. By regularly engaging in cold immersion techniques such as ice baths, in a cold tub I have witnessed a significant decrease in inflammation throughout my body. The combination of cold exposure and subsequent vasoconstriction has played a pivotal role in reducing swelling and easing discomfort caused by inflammation to help me build muscle and go beyond my limits. Cold immersion has not only helped to alleviate acute inflammation but has also contributed to a general reduction in chronic inflammation, helping me to improve my well-being. When i consistently use cold immersion as apart of my workout routine, the anti inflammation has allowed me to be faster and more fit.

REDUCE MUSCLE SORENESS

ACCELERATE RECOVERY, INCREASE MOBILITY & BOOST PERFORMANCE

Cold water immersion has become one of the most popular recovery strategies that athletes adopt for training and competition. A systematic review with meta-analysis of 68 papers highlighted that cold water immersion decreases inflammation, soreness, perceived fatigue, and drastically increases perceived recovery.

KASEY'S STORY

As a firefighter of 20 years at a busy engine company, cold water immersion has benefitted my life in a profoundly positive way. My joint pain and inflammation has been nearly erased after several cold plunges a week, and my recovery time between workouts has vastly improved. My heart rate variability is markedly improved on days I cold plunge, as well as my sleep scores. More importantly, nothing has helped ease chronic anxiety levels over the years like a 3 minute immersion into ice water!

IMPROVE SLEEP QUALITY

LIVE EACH DAY WITH ABUNDANT ENERGY

Sleep is the cornerstone of health and wellness. Cold water immersion has been shown to improve your sleep efficiency through reduced nighttime cortisol levels, fewer nighttime arousals, and an improved circadian rhythm due to greater thermoregulation from brown adipose tissue activation. 

AMANDA'S STORY

Since I began consistently using Edge, I’ve noticed a dramatic change in my sleep! I used to toss, turn, and could never get comfortable. For 5 days in a row I’ve slept through the night waking up so refreshed. The edge has been a life changing experience for me and I’ll never look back! Stay frosty, friends.

STRENGTHEN IMMUNE FUNCTION

SUPERCHARGE YOUR HEALTH

A healthy immune response not only fights infections, invaders, and pathogens but also supports athletic recovery. Cold water immersion can help to increase white blood cell count, including t lymphocytes, and reduce auto-immune responses and chronic inflammation.

RUBY'S STORY

Being a busy mom of 3, I need to make sure that any time that I do have to myself – I make count. There's fewer things that give you more bang for your buck than a 3 minute ice bath! It gives me the boost I need AND most importantly it keeps me healthy. Since incorporating the Edge Tub into my daily routine, I swear I've been sick less and able to support my family even more as a result.

SHARPEN COGNITION

BOOST YOUR FOCUS, PRODUCTIVITY & EFFECTIVENESS

Low levels of noradrenaline are a known cause of depression, decreased focus, and reduced cognitive function. The cold shock of cold water immersion elicits a robust noradrenaline response associated with vigilance, focus, attention, and mood. Furthermore, performing cognitive tasks or mental games while practicing cold water immersion may help to improve memory and executive function. 

LAINE'S STORY

Being a psychiatric mental health nurse practitioner, I love to geek out on the effects cold water immersion has on neurotransmitter activity, specifically norepinephrine. On long work days, I will often take a plunge on my lunch break. We all know the doom of the all-too-common post lunch lull. I’m able to avoid that altogether and instead cold water immersion is like a reset for my brain increasing my attention to detail, improving my active listening skills, and sharpening my ability to problem solve. Cold water immersion is a FULL SEND for frontal lobe functioning!
