Why Do I Feel Weird After an Infrared Sauna? 5 Recovery Tips

Feeling weird after an infrared sauna may be caused by dehydration, a temporary drop in blood pressure, or overheating. If you feel dizzy, nauseous, weak, or headachy, leave the sauna, cool down, and rest. Sip water if you are fully alert and able to swallow. Severe or persistent symptoms require medical attention.

An infrared sauna can be a relaxing part of your home wellness routine, but feeling sick afterward is a reason to pause. This WizziSauna guide explains possible causes and five practical ways to recover.

Why Does an Infrared Sauna Make Me Feel Weird?

The symptoms below can have several causes. How you feel alone cannot confirm which one is responsible.

Dehydration from sweating

Sweating causes fluid loss. If you enter a sauna already dehydrated or lose more fluid than you replace, you may develop a headache, dizziness, or weakness. These symptoms can also occur with heat exhaustion. CDC

A temporary drop in blood pressure

Heat widens your blood vessels, which can lower blood pressure. This may leave you feeling lightheaded, especially when standing up after a session. Harvard Health

Too much heat exposure

Feeling nauseous, unusually weak, or dizzy can signal heat exhaustion. Do not assume these symptoms are a harmless part of your infrared sauna experience. CDC

How to Recover After an Infrared Sauna: 5 Tips

1. Leave the Sauna and Cool Down

Stop your session as soon as you feel unwell. Move to a cool room, loosen unnecessary clothing, and place cool, damp cloths on your skin.

If you feel faint, sit or lie down somewhere safe. Avoid getting into a shower while dizzy, where you could fall. Cooling the body is a key first-aid step for heat-related illness. Mayo Clinic

2. Sip Water and Replace Lost Fluids

If you are fully alert and can swallow comfortably, sip cool water. Take small, regular sips instead of forcing yourself to drink a large amount quickly.

An electrolyte drink may help after heavy sweating, but it is not required after every session. If you have prescribed fluid or sodium restrictions, follow your clinician’s guidance. Mayo Clinic

3. Rest Until You Feel Steady

Stay in a cool place and give yourself time to recover. Stand up slowly, and postpone exercise or other strenuous activities.

Do not drive while dizzy. If you feel significantly unwell, ask someone to stay with you while you arrange medical help. Rest is part of the recommended response to heat exhaustion. Mayo Clinic

4. Avoid Alcohol

Choose water instead of alcohol during recovery. Alcohol can increase the risks associated with sauna use, so avoid it before and during sessions as well. Harvard Health

Skip any additional sauna session while you are still feeling unwell.

5. Adjust Your Next Sauna Session

Once you have fully recovered, use a shorter session and a lower temperature within your sauna’s operating instructions. Let your comfort guide you, and leave immediately if symptoms return.

If you repeatedly feel sick after an infrared sauna, stop using it and speak with a healthcare professional. Ask for advice before sauna use if you have low blood pressure, a heart condition, or take medications that affect your response to heat. Harvard Health

When to Seek Medical Help After a Sauna

Call 911 or your local emergency number if someone becomes confused, loses consciousness, has a seizure, or may have heatstroke. Move them to a cooler place and begin cooling them while waiting for help. Do not give drinks to someone who is confused or unconscious.

Seek medical help promptly if you are vomiting, symptoms worsen, or symptoms last longer than one hour despite cooling and rest. CDC

Frequently Asked Questions

Is it normal to feel dizzy after an infrared sauna?

Dizziness can occur because of heat exposure, fluid loss, or a drop in blood pressure. End your session and recover somewhere cool. Do not treat recurring dizziness as something you need to push through. Harvard Health, CDC

Why do I feel nauseous after an infrared sauna?

Nausea may be a symptom of heat exhaustion, particularly when it occurs with weakness, headache, or dizziness. Stop using the sauna and cool down. Get medical help if you vomit or symptoms worsen. CDC

What should I drink after an infrared sauna?

Water is a practical starting point. After heavy sweating, an electrolyte drink may also help replace lost fluids and salts. Follow medical advice if your fluid or sodium intake is restricted. Mayo Clinic

Does feeling sick mean the sauna is detoxing my body?

Feeling sick is not evidence that your sauna session is working or that toxins are leaving your body. Treat symptoms as a reason to stop, cool down, and assess whether you need medical help.

How long does it take to recover after an infrared sauna?

There is no single recovery time for everyone. Pay attention to whether symptoms improve with cooling and rest. Seek help sooner for severe symptoms, and get medical attention if symptoms worsen or last longer than one hour. CDC
