Reduces water weight When you sweat in a sauna, you lose some water, but this water weight loss is temporary. You'll gain it back when you rehydrate after your sauna session. In fact, some research on how much water you sweat out in the sauna was done to recommend how much water to drink afterward.

One study found it's common to losearound 1% of your body weightafter a 30-minute sauna session. Buthow much you sweat outdepends on several factors, including:

• How hot and humid the sauna is
• How long you stay in the sauna
• How many breaks you take (and how long your breaks are)
• How much and what you drink during your session

The total amount of water in your body can fluctuate byup to 5% a day. That's part of the reason why experts often recommendweighing yourselfat the same time every day. Temporary changes in water weight don't indicate fat loss or sustainable, long-term changes on the scale.

May boost metabolism Sitting in a sauna might help you burn more calories because your body works harder tocool you down in the heat.

In a small study, inactive men who are considered overweight sat for four 10-minute sauna sessions with 5-minute breaks in between. Theyburned more calories in the later sessions. They also had higher rates of excess postexercise oxygen consumption (EPOC). That means the men burned more calories than usual after their sauna time ended.

Over time, burning more calories can give yourmetabolisma little boost.

Lowers stress Saunas have long beenused for relaxation. Living with less stress doesn't just feel good, it can also improve your health and well-being. It might also help you achieve or maintain a comfortable weight. Whenyou're stressed, your bodystores fat differently, and you may be more likely to crave foods high in sugar and fat. That makes it harder to stick to your balanced eating habits.

What types of saunas are best for weight loss? There's no one best type of sauna for losing weight. Any sauna you use can help you burn some calories, shed water weight, and feel more relaxed.

The two maintypes of saunasare:

• Traditional saunas:Sometimes called "Finnish" saunas, traditional saunas are small, heated rooms warmed by wood, electricity, or gas. They are relatively low in humidity (compared to a steam room, which heats water to create steam that warms a room).
• Infrared saunas:Infrared light sources directly heat your body instead of the air around you.

Who should not use a sauna for weight loss? No one should rely on saunas for weight loss because they don't lead to significant or lasting results. But sauna use can be helpful in a complete weight management plan.

Saunas are generally safe, especially if you don't sit in them too long. But some people need to take extra caution oravoid saunas altogether. This includes people with heart conditions and those who arepregnant. It's also generally not recommended tolose weight during pregnancy.

Talk to a healthcare professional before using a sauna if you have any health conditions or concerns. And be sure to prioritize tried-and-trueweight-loss strategies, such as:

• Exercising regularly
• Eating plenty of fiber, protein, and nutrient-rich foods
• Getting enough sleep
• Drinking lots of water
• Enlisting help from a dietitian or other professional as needed

Should you use a sauna before or after a workout? It's generally better to use a sauna after a workout so you don't get dehydrated during exercise. And even after a workout, it's a good idea toreplace lost fluidsbefore sweating more in the sauna.

Adding sauna sessions to your postworkout routine mayease muscle sorenessand support recovery. More research is needed to understand why, but it may be because the heat improves blood flow.

" data-qa="ContentCalloutH2Title" The bottom line Sitting in a sauna burns some extra calories and makes you sweat, which can cause temporary water weight loss. You may also feel less stressed, which can support weight-loss efforts. But without a balanced diet, regular exercise, and quality sleep, you won't see major, lasting weight loss from simply using a sauna.

That said, it's generally safe to try if you're curious. Talk to a healthcare professional before using a sauna if you have any recent or ongoing health concerns. They can create a weight-loss plan tailored to your needs, and it'll be more effective than just getting sweaty.
