Recent research has shed new light on the benefits of hot water soaks for recreational athletes, suggesting they may be more effective than cold water immersion for muscle recovery. This study, conducted by a team from Ritsumeikan University in Japan, found that soaking in hot water after a vigorous workout can help improve muscle efficiency and power output—especially for sports or workouts that involve breaks.

Why Should You Take Hot Showers?

When we exercise intensely, muscle fibers are inevitably damaged, leading to soreness and fatigue. Traditionally, ice baths have been touted as the go-to method for muscle recovery, as the cold helps reduce inflammation and relieve soreness. However, the new research indicates that hot water soaks can be more beneficial for enhancing muscle function and performance in certain situations.

According to Mamoru Tsuyuki, a master's student in sports and health science at Ritsumeikan University, heat can be particularly effective for athletes who need to perform multiple times in a day, such as in sports with halftime breaks. "When you need to perform twice in the same day, such as in sports that have a halftime, heat is better," Tsuyuki explains. "During the 15 or 20 minutes, if you can immerse yourself in hot water, you can probably perform better in the second half."

Heat works by increasing blood flow, which helps with muscle repair and recovery. By boosting muscle temperature, it also improves power output, enabling athletes to recover faster and perform more effectively in subsequent sessions.

Study Was Conducted on 10 Men

For the study, 10 young men participated in a three-part experiment. After performing 50 minutes of high-intensity interval running, the participants soaked for 20 minutes in either a 59-degree cold tub, a 104-degree hot tub, or did not immerse themselves in water at all. The researchers then measured their ability to jump, testing their vertical jump height both from a standing and squatting position one hour after the workout.

The results were telling: the men who soaked in hot water showed a higher jump height compared to those who soaked in cold water. There was no difference in muscle soreness between the hot and cold groups, which suggests that while hot water may help restore performance, it does not significantly impact muscle soreness levels.

Ice Baths: Still Valuable for Muscle Soreness

While hot water soaks may be more effective for power recovery and performance, icy soaks are not without merit. Cold water immersion has long been used to alleviate muscle soreness, particularly after endurance sports. Tsuyuki acknowledges that his study focused on high-intensity interval running, and that results may vary depending on the sport.

For those who prefer cold water, Dr Putrino, a health expert, explains that ice baths can be beneficial for injuries, but they may not be ideal immediately following an intense workout. Cold water constricts blood vessels, which can cause muscles to tighten and may hinder recovery after high-intensity exercises.

Recommendations for Soak Durations and Temperatures

Experts recommend the following for both hot and cold soaks:

- Hot Water Soak:

Soak for 10 to 20 minutes in water heated to 98 to 104 degrees Fahrenheit. This temperature range is ideal for improving blood circulation and muscle recovery.

- Ice Water Immersion:

For those seeking cold therapy, the optimal time is 10 to 15 minutes in water temperatures ranging from 50 to 59 degrees Fahrenheit. For first-timers, even a 5-minute cold soak can offer benefits without overstimulating the body.

Body Mass Index or BMI is a calculation that is used to understand the relationship between your height and weight. It is very commonly used in healthcare settings and also in gyms or weight training centers. It helps fitness coaches and healthcare professionals to categorize people as underweight, normal weight, overweight, or obese. The goal of BMI is to get a rough estimate of body fat, which can then highlight potential risks for chronic health problems.

But while BMI is easy to calculate and useful as a general guideline, it doesn’t tell the full story of a person’s health.

How Is BMI Calculated?

The formula for BMI differs slightly depending on the measurement system you use.

Metric: BMI = weight (kg) ÷ height (m²)

Imperial: BMI = (weight in pounds ÷ height in inches²) × 703

For example, someone who weighs 180 pounds and is 5 feet 6 inches tall (66 inches) would have a BMI of:

(180 ÷ 66²) × 703 = 29.0

That would place them in the "overweight" category.

BMI is also divided into these categories that then determine where the person falls under the spectrum from underweight to obesity:

• Underweight: less than 18.5
• Normal: 18.5 – 24.9
• Overweight: 25.0 – 29.9
• Obesity Class 1 (mild): 30.0 – 34.9
• Obesity Class 2 (moderate): 35.0 – 39.9
• Obesity Class 3 (severe): 40.0 or higher

Generally, the higher your BMI, the greater your risk of health conditions such as heart disease, type 2 diabetes, high blood pressure, sleep apnea, fatty liver, and even certain cancers.

Is BMI Reliable?

While BMI is not a diagnostic test, it can be a helpful screening tool. It is used to track trends in population, raise awareness of weight-related risks, and to initiate conversations between patients and healthcare providers.

However, BMI often leaves out the muscle mass, bone structure, or fat distribution. One of the most common example is when an athlete with high muscle mass is classified as "overweight" despite having a low body fat.

This is why, there are other ways to measure too, including:

Waist Circumference

Excess belly fat is a stronger risk factor than fat stored elsewhere.

High risk:

Men: waist > 40 inches

Women: waist > 35 inches

Body Composition Analysis

Tools like InBody or SECA scales provide a breakdown of fat mass, muscle, and water weight—offering more detail than BMI.

DEXA Scan

This scan is the gold standard for measuring body fat, bone density, and fat distribution—but it’s expensive and not widely available.

Metabolic Health Markers

Lab tests like fasting glucose, cholesterol levels, and inflammation markers help assess overall health more accurately than BMI alone.

BMI could also vary depending on your ethnicity. More South Asians are risk for diabetes and heart disease at lower BMIs. For them, "overweight" may begin at 23 and "obese" at 25. African Americans may have higher muscle mass and lower visceral fat, which can cause BMI to overestimate health risks. Hispanic and Indigenous populations may carry more risk at lower BMIs due to genetic factors.

While it is important to care about your BMI, however, it should not be the only way to measure your health. You must also consider waist size, body composition, fitness level, blood test results, and ethnic background.

Yoga is an adaptable exercise that has poses and asanas to accommodate people according to their needs. Not everyone can perform the exercises at the same level as an experienced yoga practitioner. There are standing, flowing as well as sitting poses, these ranges allow people with all kinds of abilities to practice yoga, whether they have mobility issue, or motor control issues etc.

When it comes to conditions like heart issues, high blood pressure and blood sugar issues, people have to be very cautious. While controlling food helps them improve their health, without exercise it is not easy to do so. If you are also struggling with these issues but are unsure of what exercises you must do, try yoga. There are many poses that can help you build your health and live a healthier life like Vajrasana pose. It is a simple sitting pose that not only improves high blood pressure, but also reduces back pain, increases focus etc.

What is Vajrasana Pose?

In Vajrasana, when you kneel and sit back, it gently takes some of the pressure off your knees. This position is often used when you're doing breathing exercises to calm your mind or when you're meditating to feel more peaceful inside. People who follow Ayurvedic medicine, an old Indian system of health, believe that sitting in this way helps your body become as strong and stable as a diamond. It's about finding strength in being still and focusing your energy.

Here’s how to do it

• Begin by kneeling down on the floor. Consider placing a yoga mat underneath for added comfort to your knees and shins.
• Bring your knees and ankles together so they are touching. Point your feet straight back behind you, in line with your legs. The soles of your feet should face upward, and your big toes should touch gently.
• Exhale slowly as you gently lower your buttocks down to rest on your heels. Your thighs will naturally rest on top of your calves in this position.
• Place your hands on the tops of your thighs. Gently adjust your pelvis by rocking slightly backward and forward until you find a comfortable and balanced seated position.
• As you inhale and exhale slowly, focus on straightening your spine. Imagine a gentle lift from the base of your spine to the crown of your head, helping you sit tall. Gently press your tailbone slightly towards the floor.
• Straighten your head so you are looking directly forward, with your chin parallel to the floor. Rest your hands on your thighs with your palms facing down, keeping your arms relaxed. Breathe gently and evenly in this pose.

When Should You Avoid Doing Vajrasana

Before you start doing any yoga exercises, it's a good idea to talk to your doctor. They can tell you how yoga might affect your current health and suggest ways to do it safely so you don't have any problems. Here are some reasons why you should avoid doing this pose.

• If you have recently undergone surgery on your knees.
• If you have a condition that affects your spinal cord, particularly in the lower vertebrae (lower back)
• If you have intestinal ulcers, a hernia, or any other intestinal problems such as an ulcer or hernia
• If you are pregnant, it's important to speak with your doctor before attempting Vajrasana.
