Rate hike, rising prices in the supermarket... An

uncomfortable winter is coming,

where we Europeans will put our resilience to the test.

Seneca said that "no man is more unhappy than he who has not suffered adversity, because he dies without proving himself".

Now that the Stoics are as fashionable as in ancient times, the Danish scientist Susanna Søberg proposes an ancient practice that also multiplies her fame:

baths in cold water.

There were already numerous investigations and articles from prestigious institutions that have spoken of the

benefits of body exposure to cold.

Now, this winter bather, Doctor of Medical and Health Sciences from the University of Copenhagen with a specialty in brown fat, has compiled the most complete study on this practice in a book.

An invitation to abandon our comfortable lifestyle and perhaps also a solution to the gas problem stemming from the war between Russia and Ukraine.

THE BENEFITS

What happens when our

body comes into contact with ice water

, which feels like a knife stabbing?

It's not nice!

How to obtain advantages of a practice in which it happens so badly?

To all the people who think like this, the author replies that it is worth it because the benefits are greater.

"Heat shock causes an increase in proteins that protect cells from aging and repair them. The cardiovascular system

improves

endothelial health in blood vessels and decreases inflammation."

Positive reactions are also triggered in the brain: "They increase

dopamine, serotonin and norepinephrine,

which are crucial for mental health and reduce the risk of depression and anxiety. In nature, even more."

As if this were not enough, more calories are burned by activating the brown fat, which Søberg compares to an internal radiator, generating heat.

THE ACTIVATION OF BROWN FAT

This is our healthy fat, which burns sugar and white fat [adipose tissue] in our body when we are cold to generate heat." That is, white fat stores energy in the body, while brown, "brown," consumes it. His study showed that repeated exposure to cold activates more brown fats. As a result,

energy metabolism increases

. "In my book I thoroughly develop information about this fantastic organ, which has been ignored by science until recently about 20 years," he details, although he acknowledges that more research is needed to determine if you can create more brown fat to burn excess white fat without having to exercise.It would also be important to determine if this energy expenditure occurs in a significant way.

"Scientists are working to see how to increase browning in our bodies to

prevent obesity and diabetes

. Until we know more, we can simply enjoy the natural health and well-being that swimming in cold water provides," he says.

YOUR FROSTED BAPTISM

All this Scandinavian adventure began several years ago, when she was walking along the coast with her partner and they both saw a group of people bathing in the sea.

"

In Denmark, in the middle of winter

! It was very cold and the water must have been freezing, but they jumped in without thinking twice. They seemed happy, they were laughing with each other... So my husband and I started trying it and we ended up liking it ".

What made them repeat?

"From my own experience, I can say that feeling cold is even more beneficial when you feel sick, since it

restores your body and mind better than any medicine

" The best thing, he says, is discovering that you are able to control your nerves and spend from stress mode (fight and flight system) to relaxation mode (parasympathetic nervous system).

To start, he recommends

continuing with the cold shower routine

that we already have in place in summer.

"The transition is smoother and you get used to the cold temperatures little by little."

However, starting in winter has its advantages: "When it's cold, the air cools our body before we bathe, so the impact is less. The skin numbs earlier and we feel it less."

BODY AND COLD WATER

PARASYMPATHETIC NERVOUS SYSTEM

Upon contact with cold water, it stabilizes serotonin, a neurotransmitter that controls emotions.

BROWN FAT

Activates and uses glucose and fat from the bloodstream as fuel to produce heat in the body.

THE LUNGS AND THE HEART

Reflex gasping and hyperventilation.

Greater blood flow to the organs, reduction of pulsations.

SYMPATHETIC NERVOUS SYSTEM

Hormonal and neural activation of adrenaline, noradrenaline and cortisol as an alarm reaction.

THE BRAIN

Decrease in cognitive functions due to a 30% reduction in blood flow.

Improves mood by increasing norepinephrine.

IMMUNE SYSTEM

It is reinforced by a greater excretion of white blood cells, monocytes and a greater antioxidant system.
