Sauna: What are the Health Benefits?

Saunas have been used for hundreds of years and still continue to be popular today. Many people enjoy sitting in a sauna to unwind and relax.

Spending time in a sauna can feel good, and there may be additional health benefits to be had beyond relaxation.


Many people enjoy relaxing and unwinding in a sauna. Steam rooms involve high humidity and
moist heat as opposed to the dry heat of traditional Finnish saunas. It is vital to drink plenty of
water after using a sauna.

Spike In Teen Obesity Explained By Decreased Calorie Burn In Puberty

The rise in obesity rates during adolescence may be due to a substantial fall of calories burned during the rapid growth phase of puberty, finds a new study by the University of Exeter Medical School in the United Kingdom.

According to the Centers for Disease Control and Prevention, around 20 percent of adolescents age 12-19 years are obese in the United States. Obese teenagers are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for the development of diabetes.

Adolescents who are obese are also at a greater risk for bone and joint problems, sleep apnea, social and psychological problems, and they are more likely to have risk factors for cardiovascular diseases, such as high cholesterol or high blood pressure.


During puberty, the number of calories girls and boys burn while at rest plummets.

How Reliable Is The Glycemic Index?

Individual response to glycemic index values vary so much that it may not be useful in indicating blood sugar response, says research published in the American Journal of Clinical Nutrition.

The glycemic index (GI) of a food indicates the speed with which blood sugar can be expected to rise after a person eats it. Each food gets a score out of 100 on the index, for example, 40 for baked beans.

Glycemic load is a measure that applies the GI to a portion of food. The glycemic load for a 150-gram serving of baked beans would be 6.

GI is used to help people with diabetes to control their blood sugar. Some food labels carry GI measurements. More recently, a number of popular diets have been based on GI. Lists are available for people to check the GI and glycemic load of different foods.


People use the glycemic index as a guide to suitable foods, but is it a valid measure?

Cesarean Delivery May Increase Risk of Childhood Obesity

Children born by cesarean delivery may have an increased risk of becoming obese, compared with their siblings born by vaginal delivery, says study. This finding may have significant implications for the almost 1.3 million cesarean births per year in the United States.

Cesarean delivery is the most common U.S. surgical procedure and accounts for one third of deliveries nationwide.

The most common risk to children born via cesarean delivery is respiratory problems, while increasing evidence suggests children may also have an increased risk of other adverse health outcomes as adults.


Cesarean delivery can increase a child's risk of obesity into adulthood, study finds.

This Is Why You Have Bloated Stomach And How To Get Rid Of Bloating And Lose Weight Overnight!

What would you think if anyone told you that there’s a bacterium infecting 2/3 of the world population? You will probably just laugh it off. But there is a bacterium in the intestines which has caused issues for quite a while.

Symptoms
Helicobacter Pylori is indicated by the following symptoms: burping, bloating, diarrhea, flatulence, esophageal reflux, heartburn, constipation and upper and mid-stomach torment. For some, these symptoms are hard to relate to this bacterium. Numerous people basically regard these signs as common, so they are rarely related to the occurrence of this bacterium.

H Pylori causes gastritis, which is an irritation of the stomach lining. It is the reason for 90% of duodenal ulcers and around 80% of gastric ulcers. Also, H Pylori can cause different non-digestive conditions, such as cardiovascular issues, headaches and Raynaud’s sickness, which is the impaired circulation in the hands and feet.

This bacterium can also cause sadness and anxiety. This is in light of the fact that H Pylori can cause an absence of serotonin in the brain.

Gallstones Raise the Risk of Heart Disease by a Fifth

A new meta-analysis, using data from hundreds of thousands of individuals, finds that gallbladder disease and heart disease are more intertwined than previously thought. The reasons behind this connection are, as yet, unclear.

Gallstones are small, hard deposits that form in the gallbladder - an organ that sits below the liver.

In wealthier countries, they are a common occurrence, affecting 10-15 percent of all adults.

Gallstones are thought to be produced due to an imbalance in the makeup of bile - a digestive aid produced by the liver and concentrated in the gallbladder.

Although generally small and often symptomless, over the years, gallstones can grow to the size of pebbles.


Gallstones' links to heart disease run deeper than previously thought.

'Feeling Full' Hormone Increase in Seniors May Explain 'Anorexia of Aging'

Elderly adults often experience loss of appetite, resulting in weight loss and undernutrition. Now, researchers suggest this may be down to increased production of a hormone called peptide YY, which tells humans when they are feeling full.

Termed "anorexia of aging," loss of appetite is common among elderly adults, with around 15-20 percent of seniors experiencing unintentional weight loss as a result.

While loss of appetite in seniors can be driven by emotional issues, such as depression or grief, in many cases, no underlying cause can be found.

Previous research has suggested loss of appetite in the elderly may be down to reduced production of ghrelin - a hormone that tells humans when they are hungry.

However, the new study - conducted by Mary Hickson, professor of dietetics at Plymouth University in the United Kingdom, and colleagues - found the hormone peptide YY may be to blame.


Researchers identified increased production of the "feeling full" hormone PYY in elderly women,
which may explain why older adults often experience loss of appetite.

Science Finds a Super Easy Way to Lose Weight

Even if you order seemingly healthy dishes, your restaurant habit is likely derailing your weight loss efforts.

It’s been a long day, you’re tired, and the last thing you want to do is trudge to the grocery store and slave over the stove to make dinner. But hold up; don’t tell your hubby to meet you at your favorite restaurant just yet—especially if you’re trying to shed weight. According to a new study in the Journal of the Academy of Nutrition and Dietetics, nearly all restaurant entrées carry more calories than you should eat in a single meal. Even worse, a fair number of restaurants manage to load their meals with an entire day's worth of calories!

To come to this stomach-churning discovery, researchers from Tufts University visited both independent and chain restaurants across the country and purchased dozens of popular entrees from gyros and spaghetti to meatballs to burritos.

What It Feels Like to Live With an Incurable Bladder Disease

Nicole Abi-Najem, a 28-year old student from Toronto, has interstitial cystitis, an extremely painful bladder condition that has been likened to having a permanent urinary tract infection.

In 2012, I was working out and I went to the bathroom. When I finished peeing, I still felt like I had to go, but I knew that my bladder was empty. Doctors initially thought it was a urinary tract infection, but a test showed there wasn’t any bacteria. They gave me antibiotics, but the feeling didn’t go away. I went to a urologist, and he performed a cystoscopy to examine the inside of my bladder. He saw nothing. With both those tests clear, a specialist at Women’s College Hospital in Toronto eventually concluded that I had interstitial cystitis.

Identifying and Treating Inflammation

There are three types of inflammation: acute, chronic and life-threatening.

When basketball star Steph Curry slipped and injured his knee in late April, he reacted by tearing up on the sideline, while fans and media reacted by wondering how many games he would miss. His body? It reacted by inflaming around the outside of the knee, protecting the area as it recovered from a medial collateral ligament sprain.

The word inflammation can conjure up visuals of a swollen, red and throbbing knee or, thanks to some TV ads, a lit match doused by a medicated pad. Conventional public wisdom frames inflammation as being adverse, painful and harmful – something most people want to resolve quickly with medication.

Borderline Diabetes: What You Need to Know

The term borderline diabetes refers to a condition called prediabetes. Prediabetes is a condition in which blood sugar levels are higher than normal but not high enough to be classed as type 2 diabetes.

Prediabetes is to be considered a risk factor for type 2 diabetes. It is estimated that 10 to 23 percent of people with prediabetes will go on to develop type 2 diabetes within 5 years.

Prediabetes can be accompanied by other risk factors. It is associated with conditions such as obesity, especially abdominal obesity, high blood pressure, high blood fat levels and low levels of "good" cholesterol.

When these risk factors "cluster" together in a person, there is a higher risk of not just type 2 diabetes but heart disease and stroke as well.

Obesity Linked to Abnormal Reward Response to Sugary Foods

An unhealthy diet is considered a key contributor to obesity. When it comes to cravings for sweet treats, however, impairments in the brain's reward system might be to blame.

In a new study published in the journal Diabetes, researchers found age and receptor levels of the reward-associated chemical dopamine influence preference for sweet foods among people of a healthy weight, but not for people who are obese.

First author M. Yanina Pepino, Ph.D., of the Washington University School of Medicine, and colleagues reached their findings by enrolling 44 adults aged 20-40 years.


Researchers say the reward system in the brains of obese individuals appears to be impaired in
response to sweet foods.

Wondering why your belly fat won't disappear?

You work hard to lose weight, but the pooch won't budge. Our friends at Shape share some reasons as to why this is happening.

You can work out like a champ, eat virtuously, and get sound sleep but still stay thick around the middle. Blame some newly discovered triggers that undermine your slim-down efforts by making you pack on the belly flab. Take note, and trim down.

Living on a Busy Street
Regular exposure to traffic noise makes you 29 percent more likely to have a bigger waistline, according to findings in Occupational & Environmental Medicine. Other research found that such noise may spike your cortisol, a hormone associated with ab fat. Three suggestions for you: Drown out the noise by playing soothing music (studies revealed that such tunes lower cortisol levels), muffle the clamor with a background- noise machine, or pop in noise-canceling earbuds when you need to focus.

Your Fizzy Drink Habit
Ironically, people who sip the no-cal stuff in an effort to cut calories are actually more likely to gain belly fat. Diet soda drinkers who averaged about a can and a half a day packed 3.2 inches onto their waistlines over the course of nine and a half years, while those drinking fizzy drinks gained less than an inch, a recent study at the University of Texas Health Science Center found. One reason is that artificial sweeteners prevent the brain from registering satiety, thus increasing cravings for sweets, so you end up eating more, says study author Helen Hazuda.

Reasons Why Your Body Needs Water Every Day

We all know that water is essential for life, but have you ever wondered why your body needs so much replenishing? 

As explained in the TedEd video link below, water is crucial for the body's everyday, biological functions. The majority of the human body is made up of water: We rely on it to lubricate our joints, regulate temperature and to care for the brain and spinal cord. Without enough water, we'd be dry, unfocused, unenergized and creaky.

On average, we lose two to three liters of water a day, through sweat, breath, urine and bowel movements. To compensate, we've got to rehydrate. While past guidance has suggested we drink approximately eight glasses a day, new recommendations say we should drink anywhere from 2 to 3.7 liters (8.4 to 15.6 cups) daily, depending on a person's sex, weight, health and environment.

Still too high in fat and sodium in kids' meals.

What will it take to get children to choose fruit instead of ice cream when eating out? Despite a move by many restaurants toward healthier kids' meals, research published in the Journal of Nutrition Education and Behavior shows that while calorie ratings have improved, there is still a way to go in reducing fat, sodium and sugar.

For many American children, eating out is routine.

Studies show that, while home-prepared food has more nutritional value than restaurant meals, the diets of most children in the US already lack fruits, vegetables and low-fat dairy items.

The options available in restaurants, meanwhile, often contain excess calories, solid fats, sodium and added sugar.

Many restaurants have already begun offering healthier choices for children, in anticipation of legislation that will require calorie counts to be included on menus from December 2016.

For the past 6 years, healthier children's dishes have been among the top 10 food trends in the National Restaurant Association's annual survey of chefs.

Fat and sodium still feature excessively in kids' meals.
