Having a steam shower or sauna in your home is an incredible luxury that offers incredible health benefits. Improved circulation and muscle recovery, stress relief, and better sleep are just the tip of the iceberg. But using your home unit safely requires knowing the right temperature, timing, and preparation steps to avoid dehydration, overheating, or other health risks. Marathon runners don’t just get up one morning and decide to run 26 consecutive miles. They train and work up to it slowly. The same goes for heat therapy.
Whether you just installed your first home steam shower or your first sauna, this guide covers everything you need to get the most out of every session, safely.
Steam showers use moist heat (100% humidity) at lower temperatures, typically 100-115°F. The steam comes from a generator that heats water into vapor.
Saunas use dry heat (10-20% humidity) at higher temperatures, usually 150-195°F. Today, most saunas use electric heaters. They are more convenient and offer more precise temperature control than traditional wood-burning saunas.
Both offer similar health benefits, but the experience feels quite different due to the humidity levels.
A quick conversation with your healthcare team is recommended before starting heat therapy, especially if you're managing conditions like heart disease, high or low blood pressure, or diabetes. You'll also want to check in with them if you've had any recent injuries or surgeries or are expecting a baby.
Heat therapy, whether moist or dry, may cause dehydration, so it’s important to drink 16-20 ounces of water about 30 minutes before your session, and make sure to avoid alcohol for at least 4 hours beforehand. Alcohol increases your risk of dehydration and makes it harder for your body to regulate temperature properly.
These are signs of overheating. This is not like reps at the gym, and this is not the place for a "pushing through" moment.
Exit immediately if you experience:
The goal for most heat therapy enthusiasts is overall wellbeing. With that in mind, the following best practices will help you on your way to a relaxing and beneficial session.
Your body needs energy reserves to handle the heat stress safely. Avoid steam or sauna use if you feel sick or feverish, you’re dehydrated from illness, travel, or alcohol.
Steam showers and saunas can be incredibly beneficial when used safely. The key is starting slowly, listening to your body, and building up gradually over time. Start with shorter, cooler sessions and work your way up. Your body will thank you for the gradual approach, and you'll develop a sustainable practice that enhances your health for years to come.
Remember, there's no prize for enduring the highest temperature or the longest session. The goal is consistent, safe use that leaves you feeling refreshed and relaxed.
