5 health benefits of cryotherapy and its medical applications



Presse Santé

Followers of cold therapy claim that this way of supercooling the body can reduce pain, boost muscle recovery, and even promote weight loss. This is what research and experts say.

Health benefits of cryotherapy chambers

Cryotherapy, a form of cold therapy, has gained momentum in recent years. Many professional athletes and celebrities have said that they turn to intense body cooling methods for therapeutic purposes.

The most popular forms of cold therapy include cold water therapy, such as ice baths and ice water soaks, and whole-body cryotherapy, which uses air, not water, to achieve potentially therapeutic results. Cryotherapy consists of brief sessions in a small refrigerated chamber at temperatures between minus 90 and minus 150 degrees C.
Proponents of these cold therapies claim they can relieve chronic pain, speed muscle recovery, aid weight loss, relieve depression, and more.

Potential Benefits of Therapeutic Cryotherapy

1. May Boost Muscle Recovery After Exercise

Cryotherapy is often used to speed muscle recovery after exercise. To understand why, we must first understand what happens in the body when it cools down and warms up. First, your body responds to cold by constricting your blood vessels (known as vasoconstriction), sending all of your blood to your organs. When this happens, your blood takes on more oxygen and nutrients. Then, once you leave the cold and your body warms up again, your blood vessels dilate (this is called vasodilation), returning oxygen- and nutrient-rich blood to your tissues. This increased blood flow flushes out inflammation and toxins built up during training, helping to fuel recovery.

For example, a Chinese study published in February 2021 in The Journal of Strength and Conditioning Research showed that cryotherapy reduced muscle damage and inflammation in middle- and long-distance runners better than other forms of cryotherapy and no cryotherapy ( control). Unfortunately, the study was small (just 12 runners), so it’s hard to say how these results might apply to larger populations.

That said, previous studies have also reported decreased muscle soreness and inflammation with the use of cryotherapy after exercise, according to a previous opinion piece. However, the authors of another systematic review concluded that there was insufficient evidence to determine whether GBM actually promotes recovery after exercise better than rest.

2. It can improve sleep

Based on current data, cryotherapy can improve sleep. For example, the aforementioned Chinese study of middle- and long-distance runners not only found that cryotherapy reduced post-exercise muscle damage and inflammation, but also that subjects had better sleep quality after cryotherapy than after exercise. other forms of cryotherapy.

Researchers speculate that cryotherapy may help us sleep by helping activate the parasympathetic nervous system. This is the “rest and digest” side of the autonomic nervous system, which takes over managing bodily functions when we feel calm and safe, explains the Cleveland Clinic. And when the parasympathetic nervous system is activated, we tend to be in a relaxed state. However, more research is needed to determine if and how cryotherapy can improve sleep in non-athletic populations, and larger studies are needed to better understand the relationship between cold therapy and sleep quality.

3. May improve chronic pain

Cryotherapy can relieve chronic pain in two different ways. First, cold is a known short-term analgesic (or pain reliever). Think about it: putting an ice pack on a sprained ankle. Scientists believe that cold works by slowing nerve transmission (when a nerve sends a signal to the brain) in pain cells, according to research published in December 2020 in Pain and Therapy.

Cryotherapy can also relieve pain by reducing inflammation, a hallmark of inflammation-related chronic pain conditions such as rheumatoid arthritis and ankylosing spondylitis (an inflammatory disease of the spine), according to a research article published in December 2019 in Nature Medicine.

In fact, after reviewing 25 studies, the authors of the 2020 review in Pain and Therapy concluded that cryotherapy could be an easy, low-risk option for managing chronic pain. In particular, the pain associated with chronic diseases such as rheumatoid arthritis and ankylosing spondylitis. Cryotherapy and ice application are the two methods of cryotherapy that have provided pain relief. However, research on the long-term effects of cryotherapy in chronic pain and more standardized treatment protocols are needed.

4. Can Treat Certain Chronic Skin Conditions

Cryotherapy can also help reduce inflammation and relieve itching in people with atopic dermatitis (eczema), a chronic skin condition characterized by dry, inflamed skin. In a small study, 16 adults with mild to moderate atopic dermatitis underwent a session at -95 degrees C for one to three minutes, three times a week for a month. Atopic dermatitis symptoms improved for most patients, although the study sample was too small to draw meaningful conclusions.

5. May promote weight loss

Spending time in the cold can speed up your metabolism as your body works to keep warm. Theoretically, if you increase your calorie burn, you could create the calorie deficit needed for weight loss. In a study published in April 2021 in the International Journal of Environmental Research and Public Health, 16 lean control women and 15 obese women were subjected to decencies for five days. At the end of the study, the lean women burned 8.2% more calories at rest (known as resting energy expenditure), while the obese women burned 5.5% more calories at rest than the first day.

Uses and Health Benefits of Medical Cryotherapy

Some forms of cryotherapy, namely cryoablation or cryosurgery (a surgical procedure that uses extreme cold), are used for medical purposes by board-certified surgeons and other types of health care providers, and for specific procedures to treat certain conditions . For example, a dermatologist may use cryoablation to treat abnormal tissue, and some surgeons may use this technique to destroy certain types of cancer. It is important to note that cryoablation is a different form of cryotherapy from the curative and supportive approaches discussed above. With that said, here are two medical benefits of cryotherapy techniques used in a clinical setting:

1. Treat certain types of cancer

Cryotherapy is a common method of treating certain types of cancer, including prostate and liver cancers. This therapy, called cryoablation, involves freezing tumor cells inside the body. Tumor cells cannot survive extreme cold and die as a result, according to a previous research article.

Cryoablation is a minimally invasive procedure. To do this, the doctor inserts an instrument called a cryoprobe through a small incision in the skin and applies cold (a substance such as liquid nitrogen or argon gas) using a spray device.

However, cryoablation can only be used to treat tumors that are visible through imaging tests, such as mammograms. Also, doctors don’t yet know how cryoablation might control cancer or affect long-term life expectancy.

2. Treat abnormal skin tissue

Cryotherapy is also sometimes used to treat benign (noncancerous) and precancerous skin tissue. Freezing specific areas of skin causes the skin to blister and peel, allowing new, healthy skin to grow in its place.

2 minutes is enough to increase your longevity



Presse Santé

Don’t have enough time to exercise during the week? Or are you unable to find the motivation to do it? A new study shows that 15 minutes of vigorous exercise per week or just two minutes of vigorous exercise per day is enough. This is good news for those who do not have free time for physical activity.

Reduced risk of premature death.

This study appeared in the European Heart Journal. It shows that fifteen minutes per week or two minutes of intensive exercise per day reduces the risk of premature death by 18%.

The new study comes to support the impact of physical activity on our life expectancy.

For the study, the researchers attached activity trackers to the wrists of 71,893 adults with an average age of 62.5 for nearly seven years. Five years later, the researchers identified those who died in the meantime. People who were not physically active had a 4% risk of death during this period. In contrast, people who practiced ten minutes of exercise a week saw this risk cut in half. In total, fifteen minutes of intense physical exercise a week has been shown to reduce the risk of death by 18%.

The more you move, the better!

Of course, the more exercise you do, the better. According to the recommendations of the World Health Organization, a “healthy person” performs an average of 150 to 300 minutes of moderate physical exercise per week. You can also opt for 75 to 150 minutes of vigorous exercise per week. Research shows that these guidelines reduce the risk of premature death by 21%. Do you exercise more than the number of minutes listed above? In this case, the benefits in terms of useful life are even greater.

The benefits of sport for your brain.

More mental resilience.

When exercise is done at high intensity, the body develops physically, but also mentally, as it “adapts” to new challenges and learns to handle more load and stress. On training days, overall mental performance is better than on rest days. Memory seems to improve, as well as coordination and reaction speed.

Better mood.

Through the production and exchange of dopamine, oxytocin, serotonin, endorphins, adrenaline, etc. in the brain and in the body, the organism is rewarded with a feeling of well-being during and after exercise.

Stress management.

When your brain releases chemicals, your body “receives” stimuli to relieve pain, reduce stress and inflammation, body aches, insomnia, fatigue, and anxiety. In addition, thanks to better mental resistance, athletes can better manage stressful situations. Sport is a way to release “bad stress” and balance the body for the mental and physical challenges ahead.

improved health.

Sport strengthens the functions of the cardiovascular system, the respiratory tract and the nervous system. Sport is a key factor in “refining” your metabolism. All of this should lead to better overall health.

power charge.

In many medical and sports articles it is said that after a few minutes of sports an effect called “runner’s high” is achieved and that it is due to the chemicals that are produced “to manage” the effort. This “energy charge” includes chemicals for load resistance, stamina, pain relief, etc. The end result is a feeling of “energy” (as long as the training does not continue until exhausted by fatigue). In many articles it is mentioned that even 20 minutes of activity can already help you “get” a high energy charge.

6 questions you should ask yourself for a 100% effective diet



Presse Santé

Your weight loss success largely depends on your willingness to rise to the challenge. If you take the plunge before you’re ready, your weight loss program could fail at the first hurdle.

Knowing that you need to make changes in your life and actually making them are two different things.

Use these questions to assess your readiness to lose weight.

Are you motivated to make long-term changes to your lifestyle?

Successful weight loss depends on making permanent lifestyle changes, such as eating healthy, low-calorie foods and including physical activity in your daily routine. This could represent a significant departure from your current lifestyle.

You may need to revise your diet to eat more whole grains, fruits, and vegetables, for example. It will be important to eat a variety of healthy foods. You’ll also need to find time for physical activity, ideally for at least 30 to 45 minutes, or more, most days of the week.

Find your motivation and focus on it:

Your true motivation is the best guarantee of success, but what is it? To make these changes, ask yourself first why you want to lose weight, all these changes to:

  • have better health,
  • better appearance
  • feel better about yourself
  • better way
  • start a new love story

Have you identified anything in your life that might distract you from your weight loss goal?

If you’re dealing with major life events, such as marital problems, work stress, illness, or financial worries, you may not want to add the challenge of reviewing your eating habits and time spent being physically active. It may be better to wait until the right time to embark on your weight loss program to limit the risk of failure due to external factors that are too heavy.

Do you have a realistic picture of how much weight you will lose and how fast?

Reaching and maintaining a healthy weight is a lifelong process. Start by making sure your weight loss goal is safe and realistic, such as losing 5 percent of your current weight.

Try to start losing 0.5 to 1 kilogram per week until you reach your goal. This means burning 500 to 1,000 more calories than you consume each day, through diet and exercise.

You could lose weight faster if you change your habits significantly. However, be careful. Radical changes that are not sustainable are unlikely to be effective in the long term.

Have you resolved emotional problems related to your weight?

Emotions and food are often intertwined. Anger, stress, grief, and boredom can trigger emotional eating. If you have a history of disordered eating, losing weight can be even more difficult.

To prepare for challenges, identify emotional issues related to eating.

Do you have support around you?

Any weight loss program can be difficult. You may face moments of temptation or discouragement. Having someone around you to offer encouragement can help. If you don’t have friends or loved ones you can rely on for positive help, consider joining a weight loss support group.

If you want to keep your weight loss efforts to yourself and not tell anyone about it, it will be more difficult. But maybe you’re ready to be responsible to yourself: set up dates with yourself then. With summary about:

  • – regular weigh-ins
  • – monitor your diet
  • – track your physical activity

Have you really accepted the weight loss challenge?

If you don’t have a positive attitude toward weight loss, you may not be ready. And if you fear what’s to come, you’re more likely to find excuses to veer off course.

Instead, try to take a nice view of your new lifestyle and stay positive. Focus on how good you will feel when you are more active or weigh less. Imagine celebrating all the successes along the way, whether it’s enjoying a new food, completing another workout, or losing your first few pounds.

If you answered yes to most or all of the questions

You are probably ready to make lifestyle changes that will help you lose weight permanently. Get ahead with healthy eating and regular physical activity, starting today!

If you think you need help, see a dietitian or join a reputable weight loss program. If you have a significant amount of weight to lose, you may benefit from follow-up with a therapist or obesity specialist.

If you answer no to more than one of the questions

You may not be ready to embark on a weight loss program right now, and that’s okay. Explore what’s holding you back and face those obstacles.

Consider seeking help from a professional weight loss tracker to help you deal with any roadblocks. Then, reassess your readiness for your weight loss program so you can get off to a great start.

Ready, set, let’s go

If you can’t answer every question with a simple yes or no, but overall you feel positive and confident with your answers, consider starting now.
