Frequently Asked Questions

How do I know what sauna temperature to use in the calculator?
1. For most people, sauna temperatures range from 60°C to 90°C (140°F to 194°F). If you’re new to saunas, start on the lower end and work your way up as you get more comfortable. The calculator works best when you input the actual temperature of your sauna, so check your sauna’s display or thermometer.
What does the fitness level do in the sauna calculator?
1. Your fitness level affects how long you can comfortably stay in the sauna. If you’re a beginner, the calculator will suggest shorter times so you don’t overdo it. Advanced users can handle longer sessions since their bodies are more accustomed to the heat.
Does the sauna goal really make a difference?
1. Yes! The goal you select—whether it’s relaxation, detox, or post-workout recovery—affects your recommended sauna time. For example, relaxation might allow for longer, less intense sessions, while post-workout recovery typically benefits from shorter, focused heat exposure.
Why does the sauna calculator ask for my weight?
1. For the hydration calculator, your weight helps estimate how much water you’ll lose during the sauna session. Heavier individuals tend to lose more water, so it’s important to input your weight to get an accurate hydration recommendation.
Can I use the sauna calculator every time I go to the sauna?
1. Absolutely. Every session can be different based on the temperature, your fitness that day, and how long you plan to stay. The calculator adapts to these factors, giving you a personalized recommendation each time.
How does the sauna calorie burn calculator work?
1. The calculator estimates the number of calories burned during a sauna session by using your age, weight, height, gender, and session duration. It factors in the increased calorie burn due to heat exposure in the sauna.
Is the calorie burn accurate?
1. The result is an estimate. Actual calorie burn can vary depending on individual factors like metabolism, heat tolerance, and the specific sauna type, but this gives you a rough idea of how many calories you may burn.
What’s the difference between metric and imperial measurements?
1. In the calculator, metric measurements are in kilograms and centimeters, while imperial uses pounds and inches. You can choose whichever system you’re more comfortable with.
Does the calculator account for different sauna types?
1. Not directly, but the calculation assumes a general increase in calorie burn due to heat exposure. For more specific adjustments, you can modify the intensity multiplier (like 1.5x or 2x) for different types of saunas.
Will I lose weight just by using a sauna?
1. While saunas help you burn calories, most of the immediate weight loss comes from water weight, not fat. Regular sauna use can support overall fitness, but it should be combined with proper diet and exercise for effective weight loss.
