In the quest for effective weight loss strategies, many people are turning to unconventional methods, one of which is sauna. Though traditionally associated with relaxation and detoxification, saunas are increasingly being explored for their potential role in weight management. The intense heat experienced during a sauna session triggers various physiological responses in the body, which can influence weight loss in several ways. In this article, we'll delve into the science behind sauna-induced weight loss and also explore its other health benefits.

How Saunas Affect Weight Loss

1. Water Weight Loss

The primary way saunas influence weight is through water loss. When you’re in a sauna, your body sweats heavily to cool down from the intense heat. This sweat is mostly water, so any immediate weight loss you see is due to dehydration rather than fat loss. It’s important to remember that this weight reduction is not permanent and does not reflect a decrease in body fat.

2. Calorie Burn

Different saunas work in different ways. Conventional saunas heat the air around you, while infrared saunas use infrared light to directly warm your body without heating the surrounding air. Research from 2017 indicates that infrared saunas can burn about 400-600 calories in a 30-minute session. This can lead to a temporary increase in calorie burn, similar to what you might experience during moderate exercise. However, while saunas can boost metabolism slightly, they are not a substitute for regular exercise when it comes to achieving long-term weight loss.

3. Dehydration Risk

Excessive sweating in saunas can lead to dehydration. To mitigate health risks, it’s crucial to drink plenty of fluids before, during, and after your sauna session to stay hydrated.

Additional Health Benefits of Saunas

1. Enhanced Circulation and Heart Health

Sauna use can increase your heart rate to 100-150 beats per minute, similar to moderate exercise. This boost in heart rate improves circulation, which can help reduce muscle soreness, improve joint mobility, and alleviate arthritis pain. Regular sauna use has been linked to a reduced risk of cardiovascular diseases, potentially due to its anti-inflammatory and antioxidative properties.

2. Improved Lipid Profile

A 2014 study in the *International Journal of Occupational Medicine and Environmental Health* found that sauna use significantly lowered total cholesterol and LDL (bad cholesterol) levels after three weeks. These effects are comparable to those achieved through moderate-intensity physical exercise.

3. Skin and Respiratory Benefits

Saunas can open up respiratory passages and help loosen phlegm, offering relief from respiratory issues. They may also help alleviate psoriasis symptoms but could worsen atopic dermatitis. Regular sauna use can reduce skin plaques and scales, though its overall impact on skin health is limited.

4. Boosted Immune System

Consistent sauna use may enhance immune function by increasing the activity of white blood cells, which can help reduce inflammation and lower the risk of related health issues.

5. Relaxation and Recovery

Saunas are beneficial for muscle relaxation and recovery, especially after intense workouts. A 2023 study found that infrared saunas used post-exercise could reduce muscle soreness and improve recovery.

6. Detoxification

Some people use saunas to detoxify the body, believing that sweating helps remove toxins and heavy metals. While sweating may aid in eliminating some toxins, the effectiveness of saunas for detoxification is still being studied.

7. Better Sleep

Sauna use can enhance sleep quality by regulating the body’s circadian rhythm and reducing stress, leading to more restful sleep.

One must be very careful about what they consume. One of the easiest ways to get sick is by eating food or having beverages from unsafe and unsanitary places. That is why people are discouraged from eating at roadside stalls or food from street hawkers who do not follow the food safety protocol.

Many people do not know how unsafe tap water can be. While the tap water available at home goes through treatment, it is best to only drink it after boiling or opting for water from the filter. The Centers for Disease Control and Prevention (CDC) explains that these health issues can range from mild to serious, depending on what germs are being transmitted.

In a TikTok, Doctor Suraj Kukadia who goes by Dr. Sooj, a practicing NHS GP and emergency doctor, issued a critical warning. urgent warning that if you use regular tap water to rinse your nose, you could be exposed to a very rare but dangerous "brain-eating amoeba." Even though tap water in the UK is perfectly safe to drink, it's a different story when it comes to cleaning out your nose.

Why Tap Water Is Risky for Your Nose

Rinsing your nose is a common thing people do when they have a cold, allergies, or a sinus infection. You usually flush water or salt water into your nose to wash away snot, dust, pollen, and anything else that might be irritating your nasal passages. But in a video, a doctor known online as Dr. Sooj, explained why tap water is risky for this. He said that "tap water has bacteria. It has amoeba, it has protozoa. There are tiny living things in the water." When you drink these, your stomach acid usually kills them, but when they go up your nose, it's a different story.

Brain-Eating Amoeba

The main worry is a "brain-eating amoeba" called Naegleria fowleri. This tiny creature loves to live in warm fresh water, like lakes, rivers, and hot springs. The Cleveland Clinic explains water that contains this amoeba goes up your nose, it can travel to your brain. Once there, it causes a very serious and almost always deadly infection called Primary Amebic Meningoencephalitis (PAM). While this infection is rare, it's not worth the risk.

If the amoeba gets into the brain through the nose, it can cause a severe infection called Primary Amebic Meningoencephalitis (PAM). Early signs of PAM can be a headache, fever, feeling sick to your stomach (nausea), and throwing up (vomiting). This infection moves incredibly fast. Most people who get PAM unfortunately die within just 1 to 18 days after they start showing symptoms, often falling into a coma before death. Other symptoms can include a stiff neck, feeling confused, not paying attention to people around you, losing your balance, and seeing things that aren't real (hallucinations).

When to Seek Medical Help

Health experts like the Centres for Disease Control and Prevention (CDC) agree with this advice. They also warn about another amoeba called Acanthamoeba. If you or someone you know starts to have a headache, fever, confusion, or vomiting soon after rinsing your sinuses or nasal passages, it's crucial to get medical help right away.

A new study has revealed a sharp rise in cases of a rare cancer—appendiceal adenocarcinoma—particularly among younger generations. Generation X and millennials are seeing significantly higher rates of this cancer than previous generations, prompting concern among experts.

What Is Appendiceal Adenocarcinoma?

Appendiceal adenocarcinoma (AA) is a rare form of cancer that originates in the appendix, a small pouch attached to the large intestine. While appendix cancers are not commonly diagnosed—about 3,000 new cases per year in the U.S.—they appear to be rising at an alarming rate among younger adults.

Generational Surge in Cases

According to a new paper published in the Annals of Internal Medicine, the rate of AA has tripled among Generation X and quadrupled among millennials compared to those born in the mid-20th century. Researchers at Vanderbilt University Medical Center used data from the U.S. National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) program, which tracked cancer cases from 1975 to 2019.

The numbers are telling: the study found that for people born in 1985, the incidence of appendix cancer is four times higher than for those born in 1945. For individuals born in 1980, it is about three times higher.

A Broader Gastrointestinal Trend

Experts say this rise mirrors trends in other gastrointestinal cancers—such as colorectal and stomach cancer—which are also being diagnosed more frequently in adults under 50. Between 1975 and 2019, the researchers recorded 4,858 cases of appendix cancer, with a noticeable uptick in recent decades.

Possible Causes: Lifestyle and Diet

Although the exact reasons for this generational increase remain unclear, researchers suggest that lifestyle and environmental factors may be playing a major role. The consumption of ultra-processed foods, sugary beverages, and processed meats has increased sharply in recent decades. Additionally, obesity and metabolic syndrome—both risk factors for various cancers—are more prevalent among younger people today than in past generations.

Lead researcher Dr. Andreana Holowatyji highlighted that the increase in cases is not due to more appendectomies being performed. Surgical removal rates of the appendix have remained largely stable over time, suggesting that other factors, possibly related to diet, lifestyle, and environmental exposure, are contributing to the spike in cases.

The Challenge of Early Detection

One of the major hurdles in combating appendiceal adenocarcinoma is the lack of clear early symptoms. Many of the signs—such as bloating, appetite loss, and changes in bowel habits—are vague and can easily be mistaken for more common digestive issues. This often leads to delayed diagnoses and limited treatment options.

Urgent Need for Research

With no definitive causes identified, scientists are calling for more research into environmental exposures, genetic factors, and molecular changes that might contribute to the development of appendix cancer. Understanding these elements could help in early detection and potentially lower the rising risk among younger populations.

As per the World Health Organization (WHO), globally, over 1.2 billion people ages 30 to 79 have hypertension. The number has increased from 650 million in 1990 to 1.2 billion in 2021. This increase is attributed to many factors, including lifestyle factors, which include salty indulgence, stress, and screen time which has been increased. These three impact your blood pressure levels, know how.

What Are The Three S Worsening Your Blood Pressure?

Salt

As per the Harvard Heart Publishing, an average American consumes the equivalent of about 1 1/2 teaspoon of salt per day, which is 50% more than the recommended amount.

About a third of healthy people and about 60% of people with high blood pressure are salt sensitive.

How does salt affects blood pressure?

When you consume too much sodium, your body holds on to extra water to balance the sodium levels. This added fluid increases the volume of blood in your vessels, which in turn raises your blood pressure and forces your heart to work harder. High sodium intake can also reduce the effectiveness of certain blood pressure medications. For example, diuretics help eliminate excess sodium and water, while vasodilators work by relaxing the blood vessels. However, a high-sodium diet makes your body retain fluid again, refilling those relaxed vessels and undoing the medication's effects.

Stress

As per the official publication of State Medical Society of Wisconsin, stress can cause hypertension through repeated blood pressure elevations as well as by stimulation of the nervous system to produce large amounts of vasoconstricting hormones that increase blood pressure. Factors affecting blood pressure through stress include white coat hypertension, job strain, race, social environment, and emotional distress.

As per National Health and Nutrition Examination Survey, around 50 million American adults live with hypertension, defined as a systolic blood pressure over 139 mm Hg or diastolic pressure over 89 mm Hg. In about 95% of these cases, the condition is classified as "essential" hypertension, meaning there’s no single identifiable cause. However, experts agree that multiple factors—including stress—can contribute to rising blood pressure in these individuals.

Screentime

As per a 2024 study published in Cureus, hypertension is a major risk factor for coronary artery disease. The study links the increased accessibility of smartphones with the increasing hypertension.

This study explored the relationship between screen time and blood pressure (BP) among young adults.

The study also noted that higher screen time was more common among individuals using multiple devices. The prevalence of elevated BP in the sample was 35.8%, aligning with national data and raising concerns about the cardiovascular health of young adults.

Previous studies support these concerns. For instance, Nang et al. and Martinez-Gomez et al. linked prolonged TV viewing to higher BP and an adverse cardiovascular risk profile in adolescents. However, these relied on self-reported data. Other risk factors, such as age, gender, obesity, inactivity, and substance use, have also been linked to hypertension.
