Chilling contrast shower: interesting facts about the procedure

What's the science?

In general, water procedures are considered beneficial for the health of all body systems. As for contrast procedures specifically, it cannot be said that scientists are very interested in this issue. The lack of high-quality studies does not allow clear conclusions to be drawn as to whether contrast showers are beneficial, harmful, or act as a placebo.

In a 2021 Dutch experiment, healthy people aged 18 to 65 took a warm shower and finished with a douche of cold water. The control group bathed as usual. Over the course of three months, the number of absences due to illness among those hardening up decreased by 29%. The duration of the contrast procedure - 30, 60 or 90 seconds - did not affect the results of the experiment. However, the number of days on which participants felt sick did not differ significantly between groups. The researchers concluded that dousing with cold water after a warm shower can relieve the symptoms and progression of colds and flu.

In 2008, a review was made of studies that assessed the effectiveness of contrast water procedures for the recovery of athletes. Scientists more or less agree that the cooling phase leads to vasoconstriction, which reduces the production of pro-inflammatory elements. This should help relieve swelling and inflammation. Heat, in their opinion, improves muscle elasticity, stimulates local blood flow and relieves muscle spasms.

The authors of another paper suggest that gradually lowering the temperature while showering may improve mood and relieve symptoms of depression.

How to properly take a contrast shower to harden the body?

In order to rejuvenate and strengthen your body, you need to carry out a contrast shower according to the rules, otherwise health problems cannot be avoided. Recommendations for performing these water procedures are as follows:

Morning application. This is not only practical, since after sleep a shower helps to cheer up and finally wake up, but it is also healthier. In the evening, a contrast shower may be contraindicated; in addition, doctors insist that it can only be used three hours before going to bed, and the final procedure must be dousing with water at 25-30 degrees.
Charger. Exercise helps warm up the body and prepare it for the procedure.
Calm state. You need to be mentally prepared for a contrast shower so that there is no negative reaction from the nervous system.

You need to douse yourself with water from top to bottom, and it is best to dry yourself with a hard towel. At first, you should not stand under running cold water; wiping is permissible.

What mechanisms are hidden behind a contrast shower?

Although scientists have demonstrated that contrast procedures reduce pain, swelling, muscle congestion and even improve overall well-being, how this effect is achieved is not fully understood.

There is a hypothesis that in the acute phase of dousing, when we are trembling, the concentration of cortisol and norepinephrine increases. In this case, the greatest physiological reaction to exposure to cold water is observed in the first 30 seconds. This means that it is most likely initiated by neurogenic pathways rather than by circulating hormones. But activation of the sympathetic nervous system fully explains the long-term antidepressant effects.

Researchers also claim that the alternating contraction and relaxation of blood vessels creates a pump effect and accelerates blood flow. They are objected to that the cooling during a contrast shower is very superficial. Intramuscular temperature does not change enough to create this “pump.” Other authors have suggested that swelling is relieved by flushing out excess fluid through the lymphatic system. But the movement of lymph requires muscle contraction and does not depend on blood circulation.

Misunderstandings between scientists do not allow us to explain the effects of contrast showers only by physiological mechanisms. Perhaps psychological factors are involved or the placebo effect is triggered. The issue requires further study.

Conclusion

Hardening is the surest way to boost immunity naturally. The benefits of a contrast shower are enormous. Follow all the rules and within a month you will notice positive changes in your body and well-being.

And remember that only a completely healthy person can take a contrast shower; otherwise, consult a doctor.

Ready to try?

We provide instructions that are approved by experts.

During a regular shower, you need to make the water temperature hot, but still comfortable for the skin. When you feel that you have warmed up well, turn on the cold one. It is better if the water does not cool gradually, but immediately switches to a low temperature. In this case, the head should be left warm and not watered with cold water.

You need to stand under an invigorating shower for at least half a minute, more is not necessary. In some experiments, participants spent up to several minutes under cold water, but the effectiveness of the procedure did not increase with its duration. If you choose to cool down for longer than 30 seconds, increase your shower time gradually.

The procedure can be repeated three to five times in a row. Although even one switch of the shower was enough for participants in the Dutch experiment to improve their well-being. You need to end the contrast shower on a cold note. Rub yourself thoroughly with a towel and get dressed immediately.

Contraindications for hardening

A contraindication to hardening, or at least evidence that you are making too sudden changes in temperature, can be poor health. Therefore, it is important in general to take into account individual characteristics, listen to the reactions of your body and observe measures in setting the temperature.

Contrast showers are strictly contraindicated for the following diseases and conditions:

presence of cardiovascular diseases,
anemia,
sore throat, cystitis and other acute inflammatory processes,
malignant neoplasms (oncology),
thrombophlebitis and other hematopoietic diseases,
post-stroke condition and other neurological diseases,
some skin diseases (check with your dermatologist),
menstrual period,
respiratory viral infections,
malaria,
pregnancy and breastfeeding,
periods of exacerbation of chronic diseases,
increased body temperature,
enlarged lymph nodes,
hypertension,
spasms,
for vegetative dystonia syndrome, the procedure has a number of features that will be determined by your attending physician.

What could go wrong?

We react to cold water as to stress: the heart begins to beat very quickly, the pulse and breathing become more frequent, and the pressure rises. Healthy people effectively cope with short episodes of stress, but for “heart” and “lung patients” such experiments can result in serious problems.

The remaining warnings are within the bounds of common sense: do not get scalded and do not get hypothermic. Also, do not replace a contrast shower with taking medications and other medical procedures.

Is Charcot's shower possible at home?

It is impossible to conduct a full-fledged, according to all the rules, Charcot shower at home. Yes, this is not necessary, since the procedure, as you could read above, is not indicated for everyone, and it also has a very impressive list of contraindications.

That is why the necessity and expediency of its implementation must be determined by a doctor, and carried out by a specially trained person who, if the patient experiences any undesirable reactions, will be able to help him.

However, at home, such a useful and safe method of physiotherapy as a contrast shower will always help you. The result of regular procedures will be a healthy immune system, strong nerves and smooth, toned skin.

How to avoid getting sick after training? 7 tips from a sports doctor

To avoid getting sick after training, you need to remember a few basic rules and understand how the body works. At the moment of intense load during the training process, the speed of all processes in the body increases, and we begin to sweat. Of course, if you go outside from the locker room in this state, you can quickly catch a cold. At this moment, it is important to do everything to allow the body to cool down.

For example, a contrast shower is not a good idea.

What to do to avoid getting sick after training? How to avoid catching a cold in the fall? Let's figure it out together with a sports doctor.

In any case, after exercise, on average, up to two hours of time pass for complete recovery, when the body returns to its normal state. We tell you what to do to avoid getting sick.

A cold is a common name for acute infectious inflammation of the upper respiratory tract. It is almost impossible to independently distinguish between ARVI, influenza and now coronavirus. This is the main risk: the influenza virus can penetrate the heart muscle, myocardium and cause inflammation - myocarditis.

Finish your workout the right way

You need to understand that any workout is stress for the body and the immune system after exercise is very vulnerable. Therefore, it is necessary to take special care of yourself at this time. So, 5-10 minutes of light running and stretching after exercise will help equalize your pulse, allow your body to cool down, stabilize your condition and relax your muscles.

But you shouldn’t take a hot shower; the optimal water temperature after training is 32-35 degrees.

Drink more water

After training, drinking plenty of fluids is recommended. But you shouldn’t drink a liter of water right away; you need to gradually restore the water balance in the body. It is better to drink 2-3 sips every five minutes. This will also help cool you down.

Don't rush to go outside

A smooth change in temperature is the most important nuance, otherwise the body will not have time to adapt. Don't forget to dress well and warmly, even if you just need to run to the car. After training, it is best, of course, to go straight home or to work. The main thing is that you survive the next two hours in some closed space, then the risks of getting sick will be minimized.

Alexandra: Failure of adaptation to an increase or change in physical activity is when the body tries to adjust its systems to reduce energy costs, but it fails. This condition is expressed, as a rule, by overwork, namely a state of pre-illness or disease (signs of pre-illness are reversible, unlike the disease itself).

Stick to systematic physical activity

Physical stress is an integral part of achievement in sports, but it should not be accompanied by stress on the nervous system. Therefore, to maintain immunity, it is important to maintain sleep and wakefulness, nutrition and exercise frequency.

Get enough rest

Restoration of the body and construction of muscle tissue mainly occurs during sleep, since most of the growth hormones and testosterone are produced at this time. Night sleep is a priority, but daytime sleep also has a restorative effect. Therefore, the combination of intense training and lack of sleep, according to the doctor, can cause a cold.

Maintain temperature conditions

Incorrectly selected temperature conditions (temperature of sports facilities and the environment, clothing) can cause profuse sweating. Therefore, it is important to choose clothes from modern technological materials that will not only maintain a static temperature of the skin, but also quickly absorb moisture and dry.

When exercising outside in the cold season, you should give preference to multi-layered clothing. The bottom layer is thermal underwear, and the top layer is a windproof suit. Staying in wet clothes during the cold season is dangerous to your health.

Alexandra: Supporting the body with adaptogens - ginseng, Chinese lemongrass - will strengthen the immune system. Also, the adaptive potential of a person is increased by the increasingly popular hypoxic training, in which oxygen consumption is slightly reduced - this helps to increase the functional reserve of the body. An analogue of such an effect can be barotherapy, in which a person is placed in a pressure chamber.

Temper yourself

“Cold treatment” at ultra-low temperatures accelerates metabolism, blood flow, and has a beneficial effect on the nervous system.

Alexandra: Any cold, even in a mild form, activates cortisol (stress hormone), which means it suppresses anabolism - stops the growth of muscle tissue. During training, catabolism (muscle breakdown) starts. And recovery after training in this state will not happen. You will work your muscles to a disadvantage.

What to do? Do not exercise until all signs of a cold have completely passed. If you have suffered a severe illness (with a temperature above 37.5, a prolonged cough and runny nose), give yourself 3-4 additional days to recover.

Keeping your normal caloric intake, divide it into 4-5 meals at intervals of 3-4 hours. The emphasis should be on long-term carbohydrates.

Moreover, the fact that contrast douches help you lose weight has been proven by scientists. For example, in our body there is white fat and brown fat. But it is brown that protects our organs and is responsible for heat exchange. Since under the influence of cold water, brown fat increases heat production by as much as 15 times.

As a result, much more calories are burned, and with them, white, the most harmful fat.

This discovery was recently made by scientists at the Joslin Diabetes Center, Harvard Medical School.

Amazing effect of water contrasts

You will definitely be surprised after reading the long list of beneficial properties of a contrast shower! The benefits are in the following points:

the immune system is strengthened, the body is intensively hardened;
its thermoregulation is trained, as a result - you will stop catching colds due to hypothermia;
blood vessels are strengthened, so temperature contrast is recommended for moderate varicose veins;
The nervous system also becomes stronger, and its owner becomes calmer and more stress-resistant;
blood pressure levels are normalized;
blood circulation (including capillary circulation) is activated, thanks to which organs and tissues begin to receive more useful substances;

And a contrast shower is also a way to get away from your own weather dependence.

What effect does a shower have on the body?

A contrast shower is often characterized as a restoration shower. Its essence is quite simple - a temperature difference from hotter to quite cold. Warm water stimulates blood flow, opens the vascular system and cleanses the body. The cold flow of water sends blood inside to protect the internal organs - they suffer from the cold - and heats them. Due to the cyclical nature of the procedure, everything is repeated again and again.

For greater benefits of this option, it is recommended to use a shower in compliance with the “three in one” rule - this means using 3 times more hot water. It can be distributed in different ways. For example, take three minutes to treat with hot water, a minute for cold. There should be 3-4 cycles at a time.

You should start practicing this option for healing and hardening only after consulting a doctor. After all, it has certain benefits and harms.

Yes, not everyone immediately begins to enjoy it. At first, the main feeling is discomfort, fear or even panic! But then, as you get used to it, a person begins to enjoy the process itself. The pleasure can be made even more obvious if you know about the super benefits of this procedure.

Life story

One of my friends had 2 problems at once - difficult waking up and loose skin. As a rule, in the morning she crawled out of bed with great difficulty. Moreover, I couldn’t wake up even after 2 cups of strong coffee. And she, in general, hated the morning. In addition, there were also difficulties with the skin. Since even the most expensive lotions with innovative components did not help to remove her flabbiness.

At the same time, the girl believed that a contrast shower was just nothing more than hardening. But a therapist she knew recommended this therapy for her morning vigor and skin tone. She listened, and what do you think?

Incredibly, after 2 months the skin became more elastic. And waking up is convincing, and all thanks to contrasting douches! That’s why my friend’s reviews of this procedure are now the most enthusiastic. In addition, as a “pleasant bonus”, she also received strengthened immunity!

Dear readers! Now, I hope that you will now adopt this great way to become healthier, happier and more cheerful. Personally, at one time I felt all the delights of this extraordinary procedure.
