Quick answer: Before an infrared sauna session, arrive normally hydrated, avoid alcohol, and tell the provider about health conditions or medicines that can affect heat tolerance. During the session, speak up if you feel dizzy, weak, nauseated, unusually short of breath, or unwell. Afterward, cool down gradually and replace fluid lost through sweating.
That simple plan matters in Merritt Island and across Brevard County, where warm weather, outdoor work, beach time, boating, and exercise may already add to your daily heat exposure.
What should I do before an infrared sauna session?
- Hydrate normally. Do not wait until you feel very thirsty. Sweating increases fluid loss, and hot, humid weather can increase that loss. Mayo Clinic notes that thirst is not always an early or reliable sign of dehydration, particularly for older adults.
- Skip alcohol before the session. Heat and alcohol are not a sensible combination because both can affect hydration, alertness, and your ability to recognize that you are becoming overheated.
- Eat thoughtfully. Avoid arriving immediately after a very heavy meal, but do not deliberately fast if that makes you lightheaded. Follow any individualized medical advice you have received.
- Bring up medications and health concerns. Ask your healthcare professional before sauna use if you are pregnant, have cardiovascular concerns, have difficulty regulating body temperature, are acutely ill, or take medicines such as diuretics or blood-pressure medications. Mayo Clinic identifies some medicines and medical conditions as factors that can increase dehydration risk.
- Wear light, comfortable clothing. Follow the facility’s instructions and remove metal accessories if requested.
What does an infrared sauna session feel like?
Infrared sauna uses radiant heat in a warm enclosed setting. You should expect warmth and sweating, but a session should not feel like an endurance test. More heat or more time is not automatically better.
At iOnyx, sauna sessions are by appointment. Let the team know if this is your first session, if you have recently spent substantial time outdoors, or if you completed a demanding workout earlier in the day.
When should I stop the session?
Leave the sauna and alert staff if you develop dizziness, weakness, nausea, headache, confusion, faintness, chest discomfort, unusual shortness of breath, or any symptom that concerns you. Do not try to “push through” warning signs.
Severe dehydration or heat illness can require medical treatment. If symptoms are severe, worsen, or do not improve after cooling and hydration, seek appropriate medical care.
What should I do after an infrared sauna session?
- Stand up slowly and allow your body to cool gradually.
- Drink water and continue normal hydration through the day.
- Avoid stacking the session with heavy outdoor heat exposure if you already feel depleted.
- Pay attention to dark urine, unusual fatigue, dizziness, or extreme thirst, which can be signs of dehydration.
- Wait until you feel fully comfortable before driving or beginning strenuous exercise.
A realistic Space Coast approach
In Florida, sauna planning should account for the heat you encounter outside the treatment room. A Cocoa Beach morning, a Port Canaveral outing, yardwork in Rockledge, or an outdoor workout in Viera may change how hydrated and heat-tolerant you feel that day.
An infrared sauna is a wellness service, not a substitute for medical care, and sweating should not be marketed as proof that toxins, fat, or a specific number of calories have left the body. Current sauna research is still developing, and Mayo Clinic notes that many studies are small and often focus on traditional Finnish sauna use rather than every type of heat-based treatment.

Infrared Sauna FAQ
How much water should I drink before an infrared sauna?
There is no single amount that fits everyone. Arrive normally hydrated and follow medical guidance if you have a fluid restriction, kidney condition, heart condition, or take medicines that affect fluid balance.
Can I use an infrared sauna after a beach day or outdoor workout?
Maybe, but consider how much heat and sweating you have already experienced. If you feel depleted, dizzy, unusually tired, sunburned, or poorly hydrated, postpone the session and recover first.
Can I bring my phone into an infrared sauna?
It is usually better to leave electronics outside because heat can damage devices and distraction can make it harder to notice how your body feels. Follow the facility’s policy.
Who should ask a healthcare professional before using a sauna?
People who are pregnant, acutely ill, have cardiovascular or heat-regulation concerns, have been advised to restrict fluids, or take medicines that affect blood pressure, sweating, or hydration should ask their healthcare professional first.
