Infrared Sauna Downsides: Side Effects, Cost, Experience

What is the downside to an infrared sauna?

Infrared saunas are convenient and feel gentler than traditional saunas, but they still have drawbacks. The main downsides tend to fall into three buckets: how your body responds to heat, practical setup and cost considerations, and differences in experience compared with a high-heat steam sauna.

Heat-related side effects and who should be cautious

The most common downside is simple: heat can make some people feel unwell. Even at lower air temperatures, infrared sessions can cause dehydration, lightheadedness, headaches, nausea, or a “drained” feeling afterward—especially if you stay in too long or don’t hydrate. People with certain medical conditions, those who are pregnant, or anyone taking medications that affect blood pressure or sweating may need extra caution and medical guidance before using any sauna.

It can feel different than a traditional sauna

If the goal is the classic intense “steam room” sensation, infrared may disappoint. Infrared warms the body more directly and often feels less stifling, but it typically won’t produce the same high-heat, high-humidity environment some users expect. That difference isn’t bad—it’s just a mismatch for those who want the traditional experience.

Upfront cost, space, and electrical requirements

Another downside is practical: a quality unit can be a meaningful investment, and you’ll need dedicated space, ventilation, and a suitable power setup. Depending on the model, you may also need a specific outlet or circuit. Maintenance is usually straightforward, but you’ll still want to keep surfaces clean, manage sweat, and periodically check components.

Not everyone tolerates longer sessions

Because infrared can feel comfortable, it’s easy to overstay. That can backfire with fatigue or overheating. A safer approach is to start with shorter sessions and increase gradually.

FAQ

How long should you stay in an infrared sauna your first time?

Start with about 10–15 minutes and see how you feel. Increase time gradually over future sessions, and stop early if you feel dizzy, nauseated, or overly fatigued.
