I. Before Use: 3 Preparation Steps to Lay a Solid Foundation for Safety
1. Adequate Hydration is Key
Far-infrared saunas induce sweating via "radiant heat". Though sweat volume is less than traditional steam saunas, the body still loses water.
Recommendation: Drink 300-500ml of warm water (avoid iced water or sugary drinks) 30 minutes before use to replenish basic moisture and prevent dehydration.
For sessions over 20 minutes: Prepare an extra cup of warm water outside the sauna room for mid-session hydration.
2. Adjust Clothing and Physical State
Clothing: Wear loose, breathable cotton clothing (or special sauna clothing); avoid chemical fiber or tight-fitting clothing (may block skin respiration and sweat excretion).
Accessories: Remove metal items (necklaces, watches, rings) — far-infrared rays can heat metal and burn the skin.
Physical state: Do not use on an empty stomach (may cause hypoglycemia) or within 1 hour after a full meal (may trigger gastrointestinal discomfort).
3. Never Skip Equipment Inspection
Scenario: Before first use or after long-term inactivity.
Checks:
Power cord & heating panels: Ensure no damage or leakage.
Functions: Verify temperature controller and timer work properly.
Interior: Clean dust/debris; maintain ventilation (do not block air vents on models equipped with them).
II. During Use: 4 Key Points to Ensure Safety
1. Set Temperature and Duration Appropriately
Suitable temperature: 40-60°C. For first-time users, start at 40°C and gradually increase (max 5°C each time) after adaptation.
Duration & frequency: 15-30 minutes per session, 3-4 times a week; avoid prolonged high-temperature exposure (may cause excessive fatigue).
Timer tip: Set the duration in advance if the sauna has a timer (prevents forgetting due to relaxation).
2. Monitor Physical Reactions in Real Time
Posture: Sit or semi-recline; avoid lying flat (prevents insufficient blood supply to the brain).
Discomfort response: Immediately stop use if experiencing dizziness, nausea, palpitations, skin tingling, or difficulty breathing. Open the door for ventilation, move to a room-temperature area, drink warm water, and rest — never persist (risks health issues).
3. Avoid "Cumulative Stimulation" Behaviors
No strenuous exercise (e.g., stretching, jumping inside the sauna) — may increase heart burden.
Do not smoke or drink alcohol inside the sauna room.
For skin issues (wounds, eczema): Keep affected areas away from heating panels to prevent infection or worsening symptoms.
4. Full Supervision Required for Children
Reason: Children have delicate skin and weak temperature regulation.
Rules:
Must be accompanied by an adult.
Temperature: Keep below 40°C; single session ≤10 minutes.
Check-in: Frequently ask about their feelings; stop immediately if uncomfortable.
Prohibition: Children under 6 years old are not recommended to use.
III. After Use: 2 Post-Use Steps to Reduce Physical Strain
1. Cool Down and Replenish Water Gradually
Cooling: Do not exit immediately; open the door to adapt for 1-2 minutes before moving to a room-temperature environment.
Avoid: Sudden cold exposure (AC/fan direct blow) or cold showers (may cause colds or joint discomfort via sudden pore contraction).
Hydration: Drink warm water or a small amount of light salt water promptly to restore electrolyte balance.
2. Clean Your Body and Clothing
Skin care: After sweating, sweat and metabolic waste remain on the skin. Take a warm bath (38-40°C) 30 minutes later to clean the skin.
Clothing: Change into clean clothes to keep the body dry and prevent skin problems from prolonged sweat residue.
IV. Special Populations: Strictly Prohibited from Use in These Cases
Due to special physical conditions, the following groups face safety risks and should either avoid use entirely or only use under medical guidance:
Cardiovascular and cerebrovascular disease patients: Hypertension (uncontrolled BP >140/90mmHg), coronary heart disease, post-myocardial infarction recovery, cerebral hemorrhage sequelae. High temperatures may cause BP fluctuations and increased heart rate, raising disease onset risk.
Diabetic patients (especially insulin-dependent): Far-infrared saunas may affect blood glucose; reduced skin sensitivity increases risk of unnoticeable burns.
Pregnant and lactating women: High temperatures may impact fetal development or milk secretion — use not recommended.
Skin disease patients: Severe eczema, dermatitis, skin infections, post-burn recovery. High temperatures may worsen inflammation or spread infections.
People with weak physiques: Anemia, hypoglycemia, severe chronic fatigue syndrome. Prone to dizziness or fainting in high temperatures.
People with implanted medical devices: Cardiac pacemakers, insulin pumps. Far-infrared rays may interfere with device operation, causing danger.
