Cryotherapy is a modern-day treatment wherein the body is subjected to extremely cold temperatures for several minutes. You can just get one part of your body exposed to (localised cryotherapy) and opt for whole-body cryotherapy. The first can be done in several ways like through ice packs, ice massages, coolant sprays, ice baths and even through probes administrated into tissue. A lesser-known fact is that the use of low temperature in healing dates back to 2500 BC. However, it only came into modern practice after being used by Japanese doctor Yamaguchi in 1978 to treat people with rheumatoid arthritis.
The theory for whole-body cryotherapy (WBC) is that by immersing the body in extremely cold air for several minutes, you could receive a number of health benefits. Throughout the process, the individual stands in an enclosed chamber or a small enclosure that surrounds their body but has an opening for their head at the top. The temperature in the enclosure drops to between negative 200–300°F. The person stays in the ultra-low temperature air for between two and four minutes.
You can get benefits from just one session of cryotherapy but it is most effective when used regularly. There are many athletes who do this regularly, some athletes use cryotherapy two times every day and others will go daily for 10 days and then once a month afterwards.
1. Relieves Migraine Symptoms: Cooling the neck's carotid arteries helps reduce pain by cooling blood in intracranial vessels.
2. Eases Nerve Pain: Cryotherapy numbs irritated nerves, aiding in the treatment of pinched nerves, chronic pain, and acute injuries.
3. Improves Mood: By triggering hormonal releases like endorphins, it may help alleviate anxiety and depression.
4. Reduces Arthritic Pain: Whole-body cryotherapy can minimize arthritis pain and enhance rehabilitation.
5. Aids Cancer Treatment: Targeted cryotherapy ("cryosurgery") freezes and kills cancer cells in low-risk tumours, like prostate cancer.
6. Supports Cognitive Health: Its anti-inflammatory effects may prevent Alzheimer’s and dementia, though research is ongoing.
7. Treats Skin Conditions: Conditions like atopic dermatitis and acne may benefit from reduced inflammation and improved antioxidant levels.
Cryotherapy has a beneficial impact on your mental health too. Experts say that cryotherapy has the potential to effectively treat stress disorders like general anxiety, depression Post-traumatic Stress Disorder (PTSD), and Obsessive Compulsive Disorder (OCD.)
A 2012 study also suggested that cryotherapy can mitigate inflammation and oxidative stress, which is linked to dementia, mild cognitive impairment other age-related cognitive decline. Another study conducted in 2008 found that cryotherapy reduced symptoms by at least 50% in one-third of individuals with depression or anxiety.

Ever since the Trump administration has come to power, sentiments against vaccines have gone up. Many vaccine critiques have been handpicked by the anti-vaxxer HHS Secretary RFK Jr. as health officials. So it is no surprise that now the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices (ACIP) is now recommending that mothers who test negative for hepatitis B should discuss the need for the vaccine with their doctors. If parents choose to delay the birth dose, the first shot should be given at no earlier than two months of age. This is dropping the longstanding hepatitis B vaccine guideline that stated that every newborn receive the first dose of the hepatitis B vaccine shortly after birth. This recommendation, in place since 1991, was reversed on December 5 after a key CDC advisory committee voted to change the policy.
This committee was appointed by Health and Human Services Secretary Robert F. Kennedy Jr., who dismissed all 17 previous members earlier this year. The shift in policy has triggered wide debate, especially in the medical community, because it overturns one of the longest standing infant vaccination guidelines in the United States.
Below are some of the claims made by the panel, both sides, who debated the vaccine's need or unimportance for all infants.
Claim: Several ACIP members questioned whether babies considered “low risk” truly need a hepatitis B shot at birth. But hepatitis B is not always easy to detect or trace.
The virus spreads through bodily fluids such as blood, semen and vaginal fluids. It is also extremely resilient and can survive on surfaces for up to a week. Even tiny amounts of dried blood from everyday items like razors, toothbrushes or nail clippers can carry the virus.
Hepatitis B often has no symptoms for years. The CDC estimates that 640,000 adults in the United States live with chronic hepatitis B, and half do not know they are infected. This means that even if a mother tests negative during pregnancy, her newborn can still be exposed through family members or other caretakers. Before universal birth-dose vaccination began, only half of infected children under age ten had contracted the virus from their mothers at birth.
Because so many people are unaware of their infections, determining true risk is complicated.
Claim: Some committee members suggested that vaccinating all newborns mainly protects adults or others at higher risk.
That claim is misleading. The primary purpose of giving the shot at birth is to protect infants, who face the most severe long-term consequences of infection.
Hepatitis B attacks the liver. If an infant becomes infected, there is a very high chance the disease will progress into a chronic lifelong condition. About a quarter of those children eventually die prematurely from liver failure or liver cancer. While treatments exist to reduce complications, there is no cure.
Dr. James Campbell, a pediatric infectious disease specialist at the University of Maryland, reminded the committee that the vaccine strategy transformed public health outcomes. “We used to have 18,000 or 20,000 kids born with this every year, and a quarter of them would go on to develop liver cancer. We now have almost none,” he said.
Claim: Hepatitis B infections fell sharply after the birth-dose recommendation took effect. Before vaccination became routine, up to 300,000 Americans were infected annually. About 20,000 of those were children.
Today, total annual cases have dropped to around 14,000. Among people under 19, chronic infections have reached extremely low levels. In 2022, the CDC documented only 252 new cases in this age group.
ACIP member Dr. H. Cody Meissner, who voted against changing the policy, argued that declining numbers do not justify easing precautions. “It is a mistake to say that because we are not seeing much disease, we can change the schedule,” he said. “If we do, hepatitis B infections will come back.”
Claim: Some committee members compared U.S. policy to countries such as Denmark, which does not vaccinate all newborns.
However, the United States is far from alone in recommending a universal birth-dose. According to CDC data from September 2025, 116 out of 194 World Health Organization member countries recommend hepatitis B vaccination at birth.
Denmark does not include hepatitis B in its standard childhood schedule, but it has a centralized national health system, higher prenatal screening rates and less fragmented medical records. The United States lacks these structural advantages, which makes relying solely on maternal testing more challenging.

A senior British cardiologist has shared a clear two-word tip that he says can make a real difference to your blood pressure. Dr Amir Khan recently explained this advice while outlining five simple habits that can naturally bring hypertension under control, particularly during the winter months when heart risks tend to rise.
India continues to struggle with a heavy hypertension burden. Roughly one in three adults is estimated to have high blood pressure, yet many remain unaware of their condition, and even fewer manage it well. Doctors often warn that this lack of awareness, combined with poor control and gaps in long-term care, leads to serious complications such as heart attacks, strokes, and kidney disease. Since hypertension usually comes without symptoms, it has long been known as a silent killer.
Dr Khan highlights that a few lifestyle tweaks can go a long way, and his biggest message is built around a simple two-word mantra: “get moving”. He explained on Instagram that regular physical activity keeps blood vessels flexible and supports healthy blood flow. His advice is to pick any form of movement you genuinely enjoy and make it part of your routine.
Exercise reduces blood pressure by strengthening the heart, improving circulation, and reducing the strain on arteries. A stronger heart pumps blood more efficiently, which lowers the force exerted on blood vessel walls. Physical activity also opens up small blood vessels, helps manage weight, and reduces inflammation and stress hormones. All of these support healthier vascular function and better overall pressure control.
Doctors recommend a mix of aerobic activity, such as brisk walking, swimming, or cycling, along with strength training to support long-term heart and metabolic health.
While movement is his main message, Dr Khan also lists four additional habits that support healthier blood pressure levels.
He explains that those with high blood pressure need to be especially mindful of hidden salt. Adults should ideally stay around six grams a day, which is about a teaspoon. Much of this is already present in packaged or restaurant foods. Using herbs, spices, and fresh ingredients can help bring the total down.
Dr Khan encourages increasing potassium intake because it helps the kidneys flush out excess sodium. Foods rich in potassium include bananas, tomatoes, spinach, carrots, and kiwi. Adding these regularly can make a noticeable difference.
He stresses that avoiding cigarettes and limiting alcohol is key for heart health. Smoking damages blood vessels and raises blood pressure, while alcohol can worsen both pressure and weight control.
Keeping weight in a healthy range reduces strain on the heart and helps blood vessels function more efficiently. It also improves circulation and reduces the substances that cause vessels to tighten.
Dr Khan’s message is simple. Small and consistent lifestyle choices can noticeably lower blood pressure, and starting early makes a significant difference.

A new study in the European Heart Journal has shed light on a worrying trend. People living with Type 1 and Type 2 diabetes face a much higher risk of sudden cardiac death, and this risk contributes to a significant loss of life expectancy. The findings also suggest that the true burden of sudden cardiac death in the diabetes population has been underestimated until now.
Sudden cardiac death refers to an unexpected loss of heart function, often triggered by a sudden electrical disturbance in the heart. While many people assume this happens mainly to those with known heart problems, earlier research has shown that a large number of cases occur in individuals without diagnosed cardiac disease. This means vulnerable groups like people with diabetes may slip through the cracks of current prevention strategies.

People with diabetes already face a shorter lifespan compared to the general population. On average, a 30-year-old with Type 1 diabetes loses about 14.2 years of life, while someone with Type 2 diabetes loses around 7.9 years. A major share of this reduction is linked to cardiovascular disease, and the latest study estimates that sudden cardiac death alone accounts for 3.4 years lost in Type 1 diabetes and 2.7 years in Type 2 diabetes.
To better understand the scale of the problem, researchers examined a nationwide cohort that included every person living in Denmark throughout 2010. For those who died during that year, detailed information was collected from medical records, autopsy findings when available, and death certificates. Two physicians independently reviewed every potential sudden death to ensure accuracy.
The dataset included more than 5.5 million people. During the year, 54,028 deaths occurred, and more than 14 percent were sudden deaths. People with diabetes made up a significant portion of these cases. There were 25,020 individuals with Type 1 diabetes and 172,669 with Type 2 diabetes, with 97 and 1,149 sudden cardiac deaths recorded in each group.
People with diabetes who experienced sudden cardiac death tended to be younger and more often male compared with people without diabetes. They also carried a heavier burden of other medical conditions, including ischemic heart disease, heart failure, arrhythmias, kidney disease, and even mental health issues. A notable proportion of these patients had also been hospitalized for diabetes-related complications such as hypoglycemia, which researchers believe could play a role in triggering sudden cardiac events.
The incidence of sudden cardiac death in the general population was 105 per 100,000 person years. In contrast, it climbed to 394 for people with Type 1 diabetes and 681 for those with Type 2 diabetes. The relative risk was especially striking among younger adults. For example, people between 30 and 40 with Type 1 diabetes had more than twenty times the risk compared to those without diabetes.
The research team used multiple statistical models to adjust for factors like age and existing disease, and diabetes consistently emerged as an independent risk factor. The findings confirm that sudden cardiac death is responsible for a meaningful portion of life years lost in people with diabetes. They also point to a need for better screening, earlier management of cardiovascular risks, and more focused research into why this group is so vulnerable.
