When trying to achieve weight loss or improve skin tone, it's beneficial to utilize a variety of methods to enhance your efforts. Adding different approaches can contribute to overall progress. While a hot tub can't replace a healthy diet and regular exercise, it can support a healthy lifestyle.
The Science Behind Hot Tub Weight Loss
The idea that hot tubs can contribute to weight loss stems from several physiological effects. Research suggests that spending time in a hot tub can mimic some of the effects of light exercise. The heat of the water causes blood vessels to dilate, boosting circulation and gently raising the heart rate. This process is similar to what happens in the body during physical activity. As the body works to cool itself down, it burns extra calories.
Passive Calorie Burning
Hot tubs offer passive calorie burning, meaning you can burn calories without rigorous exercise. A study by Steve Faulkner, Ph.D., an exercise physiologist at Loughborough University, found that relaxing in hot water for an hour can burn around 140 calories. While this may not be as effective as a strenuous workout, it can still contribute to your overall weight loss efforts.
Metabolism Boost
Metabolism is the process your body uses to convert food into energy. A higher metabolic rate means your body burns more calories, even when at rest. Soaking in a hot tub can naturally raise your heart rate and increase blood flow, which in turn stimulates your metabolism.
Stress Reduction and Cortisol Levels
High stress levels can trigger the release of cortisol, a hormone that can lead to weight gain, especially around the midsection. Using a hot tub for weight loss can reduce everyday stress and lower cortisol levels. By promoting relaxation, hot tubs can help prevent unhealthy cravings, increased body fat content, and hindered muscle growth.

Improved Sleep Quality
Sleep is essential for weight loss. Sleep deprivation can negatively affect hormones and other bodily systems. Insomnia can boost cortisol levels, leading to unhealthy cravings and increased fat storage. It can also cause a boost in ghrelin, a hormone that triggers hunger, making it hard to stick to an eating schedule. Hot tubs can relax the body and mind, making it easier to fall and stay asleep. By lowering cortisol levels and promoting better sleep, hot tubs can indirectly aid in weight loss.
Hot Tubs and Cellulite Reduction
Cellulite, the lumpy or dimpled skin often found on the thighs, hips, and buttocks, can be a persistent concern for many. Factors like genetics, hormones, and skin thickness contribute to its development. While eliminating cellulite completely can be challenging, hot tubs can help improve its appearance through:
- Improving Circulation: Soaking in a hot tub increases blood flow, which improves circulation to areas affected by cellulite.
- Reducing Fluid Retention: Fluid retention often makes cellulite appear worse by causing swelling and puffiness in certain areas.
- Toning Body Tissues: The warm water in a hot tub helps relax and tone body tissues, including the skin and muscles.
Hot Tubs and Injury Recovery
One of the more practical ways spas can help with weight loss is by promoting healing from injuries that prevent regular workouts. Temporary pain relief and improved circulation are key benefits. Hot tubs cause blood vessels and capillaries to dilate, allowing blood to flow more freely. Increased blood flow to injured areas promotes faster healing.
Maximizing Hot Tub Benefits for Weight Loss
To get the most out of your hot tub for weight loss, consider the following:
- Consistency: Aim to soak several times a week to help with circulation and fluid retention.
- Duration: Soak for around 20 to 30 minutes per session to allow your body to get the full benefits without overdoing it.
- Combination: Combine soaks in the hot tub with other healthy habits to maximize the benefits.
- Temperature: Ensure the water temperature is appropriate, generally not exceeding 104 degrees Fahrenheit.
Hot Tub Exercises and Stretches
While simply soaking in a hot tub offers benefits, incorporating gentle exercises and stretches can enhance the experience and contribute to weight loss goals. The hot water increases blood flow, loosening tension and allowing a greater range of motion and flexibility.

Stretches
- Torso Twist: Sit with shoulders submerged, grab your right knee with your left hand, and twist to the right. Hold on to the edge of the hot tub with your right hand and look over your right shoulder to deepen the stretch. Repeat on the other side.
- Hamstring Lengthening: Use both hands to grab your right foot under the water. Straighten your leg directly in front of you. Alternate flexing and pointing your foot but don’t lock your knee. Repeat on the other side.
- Front Shoulder Stretch: With both hands, grip the front edge of your seat. Edge your glutes off of the seat and dip your hips low while still holding on with your hands.
Exercises
- Core Work: Grip your seat with both hands while bringing your knees up to your chest. Then, fully extend both legs together. Keep your back straight and your shoulders down.
- Leg Kicks: Pedal your legs in and out as if riding a bike. Alternatively, keep your knees bent at a 90-degree angle and lift your knees up and down toward the surface of the water.
- Arm Lifts: Submerge your arms under the water and extend them straight out from your sides. First, clap your hands together. Then, flap your arms like you’re trying to fly.
Swim Spas: A Step Up
For a more comprehensive workout, consider using a swim spa. These spas offer more room for exercises and stretches and often have a built-in jetted swim current system. The current system makes swimming in a spa easier and allows for effective workouts. Many swim spas also come with multifunctional fitness kits, including adjustable row bars, handles, and resistance bands.
Important Considerations and Precautions
While hot tubs offer numerous benefits, it's important to use them safely and be aware of potential risks:
- Temperature: Hot tub water temperature should not exceed 104 degrees Fahrenheit.
- Duration: Limit soak times to avoid dehydration and dizziness.
- Hygiene: Choose hot tubs that are regularly cleaned and maintained.
- Medical Conditions: Consult your doctor before using a hot tub if you have cardiovascular or respiratory conditions, peripheral neuropathy, or are pregnant.
- Certain Groups: The elderly, young children, and pregnant women should exercise caution when using hot tubs.
- Maintenance: Perform regular maintenance to keep the hot tub clean and address any problems.
- Avoidance: Avoid hot tub use if you have swelling or infection, open sores or wounds, or have experienced an allergic reaction or skin condition from water treatment chemicals.
- Supervision: Avoid using a hot tub alone if you are feeling tired, dizzy, or drinking alcohol.
Hot Tubs for Overall Wellness
Beyond weight loss, hot tubs offer a range of benefits that contribute to overall well-being:
- Cardiovascular Health: Hot water can help with circulation, lower blood pressure, and reduce artery stiffness.
- Sleep Improvement: Soaking in a hot tub before bed can help regulate body temperature and promote better sleep.
- Mental Health: The warmth of the water can calm the nervous system, reduce stress, and promote relaxation.
- Pain Relief: Hot tubs can provide relief from muscle and joint pain.
- Improved Recovery: Soaking in hot water can help muscles recover faster after exercise.
