Most sauna safety articles focus on everything that can go wrong. A better approach is understanding how to use your sauna comfortably, consistently, and in a way that supports your health goals.
For most healthy adults, sauna safety comes down to three simple principles:
• Hydrate.
• Start slowly.
• Listen to your body.
Listen To Your Body
If there is one rule more important than any other, it’s this:
Listen to your body.
If you ever feel light-headed, dizzy, nauseous, or unwell during a sauna session, leave the sauna immediately, hydrate, and allow your body to cool down.
Every person responds differently to heat. Age, fitness level, medications, hydration status, health conditions, and experience with sauna use can all influence how your body reacts. The goal is not to push through discomfort. The goal is to create a sauna routine that supports your health and wellness over the long term.
Start Slowly
For most healthy adults who are new to sauna use, I recommend starting with three to five sessions per week for 30 minutes and paying attention to how your body responds.
As you use your sauna consistently, your body will become more efficient at releasing sweat.
For individuals recovering from significant illness, managing chronic conditions, or taking multiple medications, it may be beneficial to start more gradually and monitor how you feel between sessions. If you feel unusually tired, fatigued, or uncomfortable the following day, consider taking a day off, hydrating, and allowing your body additional recovery time before your next session.
Hydrate Before, During, and After
I generally recommend drinking approximately half your body weight in ounces of water per day to maintain healthy hydration. It’s also important to drink water before, during, and after your sauna session.
Your body cannot release water it doesn’t have available to release. Sweat is one of the body’s natural waste elimination pathways, and proper hydration helps support normal sweating and recovery.
One practical observation from years of helping sauna users is this: if you normally begin sweating within the first several minutes of a session and suddenly stop sweating at your usual rate, dehydration is often the first thing worth considering. Sometimes the best thing you can do is take a day off, hydrate, and return to your normal routine once your body has recovered.
Hotter Isn’t Always Better
One of the biggest sauna safety myths is that hotter automatically means better.
Many new sauna users assume they should preheat the sauna to its highest setting before getting in. In reality, I typically recommend preheating an infrared sauna for about 10 to 15 minutes or until it reaches approximately 100°F.
Once the sauna reaches a temperature above a low-grade fever, your body becomes less able to rely on the surrounding air to cool itself, encouraging the sweating process. From there, most users can gradually increase the temperature as the session progresses.
Many infrared sauna users report excellent results at temperatures around 118°F to 125°F.
Don’t Use The Sauna After Drinking Alcohol
Alcohol and dehydration are a poor combination.
If you’ve been drinking alcohol, allow your body time to rehydrate before using the sauna. Entering a sauna while dehydrated increases the likelihood of an uncomfortable session and makes it more difficult for your body to regulate itself effectively.
Special Considerations
Women who are pregnant or breastfeeding should consult their healthcare provider before beginning sauna use.
Individuals with significant medical conditions, those currently undergoing treatment for serious illnesses, or those taking medications that affect heat tolerance, hydration, or blood pressure should also discuss sauna use with their healthcare provider before beginning a new routine.
When in doubt, a conversation with your physician is always appropriate.
Three Simple Sauna Safety Rules
If I could only give a new sauna owner three pieces of advice, it would be:
• Hydrate.
• Start with three to five 30-minute sessions per week.
• Listen to your body.
Final Thoughts
At the end of the day, the goal is simple:

Safe sauna use isn’t about pushing your limits. It’s about creating a routine that supports your health goals while remaining comfortable enough to continue long term.
