What you need to know about the frequent cold showers

However, it wouldn't be until 1995, driven by his sadness over the unfortunate passing of his first wife Marivelle-Maria, that Hof developed techniques to survive exceedingly low-temperature environments.

He has since come under medical assessments for his ability to withstand low temperatures, holds the world record for swimming under ice and running half a marathon, barefoot, above the Arctic Circle.

It is this reputation for braving the cold, that he has been renamed Wim "The Iceman" Hof.

Safety

In Wim's experience, the outdoors and the cold have an 'avalanche of health benefits' including, but not limited to, improved sleep and a tough immune system.

However, you are advised to get medical advice from a doctor before going under your regular water temperature. Address any health concerns to do with heart problems, hypertension, autoimmune problems, among others.

Cold showers do not mean ice-baths or freezing, 21°C or lower is pretty low. If you experience discomfort, you have probably gone too far, according to Hasit Jethwa, health and fitness tutor at The Training Room.

Ease yourself into the lifestyle by turning the temperature down at the end of a regular shower, for about 30 seconds, and gradually increase you time under as you build endurance. Try and find what works best for you.

Benefits

Quick recovery

The cold typically stimulates blood vessels bringing about vasoconstriction. During this process, blood is redirected to vital organs, through the heart and lungs, so oxygenated can be pumped faster around the body to deliver fresh oxygen and nutrients.

"The cold also helps to reduce any potential inflammation you might experience post exercise, which can help to speed up your recovery, and reduce your aches and pains," Jethwa says.

Relief for mental disorders

The shock of a cold shower helps take the mind off anxieties or a low mood forcing attention to the present moment. It also improves focus and alertness.

According to a study done at Virginia Commonwealth University School of Medicine, a cold shower for 3 minutes, once or twice a day, stimulates activates the sympathetic nervous system through the high density of cold receptors in the skin, sending lots of electrical impulses to the brain.

Repeated exposure under the cold also triggers a reduction in the stress hormone, Cortisol.

Pain relief

During vasoconstriction, as blood is redirected to vital organs, swelling and soreness is reduced and pain signals are transmitted slower under cold temperatures, according to a study by North American Medical.

Better skin complexion

Cold water temporarily closes skin pores, constricts blood vessels, in attempts to preserve body heat. This reduces swelling, itching and irritation. Cold water also preserves skin protective oils unlike hot water.
