Ice Guide

Multiple sources now prove that a practice of cold water therapy is unequivocally good for us. Here's your free guide why and how to get yours!

The science


The cold triggers our metabolism, our internal furnace, by releasing free form fatty acids (FFAs) and glucose. It also protects against insulin resistance that can lead to diabetes and atherosclerosis by inhibiting glucose production. The collaborative effects of vasodilation and vasoconstriction work together to switch our metabolism to fat burning mode.


Our immune system is influenced by multiple factors and is highly complex. In isolation, the benefits of cold water immersion are hard to measure. But several studies now link cold exposure to immune boosting benefits such as increased production of ‘killer T cells’ and lymphocytes, a type of white blood cell key to immune function.


We each have 70,000 miles of veins, arteries and capillaries moving blood around our bodies. For most, this great vascular tree is de-conditioned through lack of exposure to the big temperature changes it was designed to deal with. When we move between hot and cold, it gives those tiny muscles governing blood-flow a serious workout.


Regular cold water immersion drives wakefulness, alertness, learning and attention, enhanced memory formation and retrieval. It also supports top-down regulation of pain. It also increases dopamine by 250%, a natural ‘feel-good’ hit.

Get Your Cold On®

Whether it’s cold showers, ice cold dips in a lake, waterfalls, or a simple tub in the garden — we want to empower people to develop a safe, accessible and reliable cold contrast or cold water immersion practise. Resetting mind and body, feeling stronger and happier in just a few minutes per day. However you can do it, just get your cold on.

More about Brass Monkey®


Getting into cold water is no walk in the park. So when things seem mentally tough, we find it best to keep things simple. And it doesn’t get more simple than our 5 steps for newbies to the cold.

Before you read any further, it should be noted that the suggestions that follow detail physical challenges for advanced dippers only. Cold water is fun, but it’s not a game and should always be treated with respect. It’s a powerful tool that should be used with care. It’s no place for ego or competition.

This particular health benefit claim may have been popularised by a 2016 Dutch study where users of daily cold showers showed a reduction in self-reported sickness . Since then, there have been numerous studies showing that cold exposure, typically in winter ice swimmers, increases the plasma levels of a number of different immune cells. Quite simply, more immune cells in your blood is generally a good thing.
