Saunas have long been associated with wellness and relaxation, but can saunas help you lose weight? Can sitting in a hot room actually help shift stubborn pounds? This article explores the science behind sauna use and weight loss, separating myths from facts and providing clarity for those on a fitness or wellness journey.
Whether you’re a seasoned sauna user or considering trying it for the first time, understanding what’s happening to your body in the heat is key.
Let’s explore what saunas can and can’t do for weight loss and how experiences like those offered at Wild Ritual Sauna Scotland can support your health goals in a holistic way.
What Happens to Your Body in a Sauna?
When you step into a sauna, particularly a traditional wood-fired sauna like those used at Wild Ritual Sauna, your body responds almost immediately:
Your heart rate increases, mimicking the effect of light exercise.
Blood vessels dilate, promoting better circulation.
You begin to sweat heavily, which is your body’s natural way of cooling down.
These effects can make you feel like you're working out, but the truth about fat loss is a bit more nuanced.
Does Sitting in a Sauna Burn Calories?
Yes, but not as many as you might think.
According to research published in the Journal of the American Medical Association, a sauna session can increase your calorie expenditure. For example:
A 30-minute session in a sauna may help you burn approximately 50–100 calories, similar to a brisk walk.
This is mainly due to elevated heart rate and increased energy expenditure from maintaining core temperature.
However, this is not the same as burning fat. Most of the weight lost immediately after a sauna session is water weight, which is quickly regained once you rehydrate.
The Role of Water Weight vs Fat Loss
One of the biggest misconceptions is that the pounds you see drop after a sauna session are fat loss. In reality, this is primarily:
Sweat loss
Dehydration-related weight drop
This can be misleading, especially for those trying to track progress using scales. The weight comes back once fluids are replenished.
So, while you might feel lighter and leaner, true fat loss only occurs when there’s a sustained calorie deficit through exercise and diet.
Where Saunas Can Help in a Weight Loss Journey
While saunas are not a magic solution for fat loss, they can be a valuable tool in a wider wellness programme:
1. Supports Muscle Recovery and Reduces Inflammation
Regular sauna use reduces delayed onset muscle soreness (DOMS) and inflammation, allowing you to train more consistently, a key factor in weight management.
2. Improves Sleep Quality
Quality sleep is critical for hormone regulation, including those that govern appetite (ghrelin and leptin). Sauna use can promote better, deeper sleep by reducing stress and helping the body wind down.
3. Boosts Cardiovascular Health
Long-term sauna users show improved heart health, better circulation, and even lower risks of cardiovascular events, according to a 20-year Finnish study.
4. Enhances Mental Resilience
Mental well-being and stress management are vital when trying to lose weight. Saunas offer a moment of stillness, mindfulness, and even spiritual reflection, especially when paired with nature, such as in a Wild Ritual Sauna experience by the sea or river.

Conclusion: Can Saunas Help You Lose Weight?
In short, saunas can support your weight loss journey, but they are not a shortcut or replacement for healthy eating and exercise.
They may help:
Burn a modest number of calories
Improve recovery and consistency in training
Support sleep and stress reduction
Boost cardiovascular and metabolic health
Used mindfully and regularly, saunas can be a powerful ally in your wellness toolkit, just don’t expect them to do all the work.
5 Frequently Asked Questions
