Walaupun katil terapi lampu merah secara amnya selamat untuk kebanyakan orang, keadaan dan situasi tertentu mungkin menimbulkan risiko. Di bawah adalah senarai terperinci kontraindikasi (bila untuk mengelakkan RLT) dan langkah berjaga-jaga untuk dipertimbangkan.
Kontraindikasi mutlak (Elakkan Sepenuhnya)
- Active Cancer or Tumor Risk
kenapa? Red/NIR light may stimulate cellular activity, theoretically promoting cancer cell growth.
Pengecualian: Sesetengah klinik menggunakan RLT di bawah pengawasan perubatan untuk kesan sampingan yang berkaitan dengan kanser (cth., mucositis mulut).
- Kehamilan
kenapa? Limited research on fetal safety; potential risk of overheating (if combined with heat-based therapies).
Alternatif: Use only on small areas (cth., muka, hands) after consulting a doctor.
- Photosensitivity Disorders
Conditions: lupus, porfiria, xeroderma pigmentosum.
kenapa? Abnormal skin reactions to light, leading to rashes or burns.
- Penggunaan Ubat Fotosensitisasi
Drugs to Watch For:
Antibiotics (tetrasiklin, ciprofloxacin).
Retinoid (Accutane, tretinoin).
Ubat kemoterapi (5-FU, methotrexate).
kenapa? Increased risk of burns or hyperpigmentation.
Relative Contraindications (Use with Caution or Medical Approval)
- Thyroid Disorders
Concern: Inframerah dekat (NIR) light may temporarily affect thyroid function (especially hyperthyroidism).
Precaution: Limit neck exposure; monitor symptoms.
- Epilepsy or Seizure Disorders
kenapa? Bright, flashing lights (in some devices) could trigger seizures.
Penyelesaian: Use steady, non-pulsing light settings.
- Eye Conditions
risiko: Retinal damage from prolonged direct exposure (though RLT lacks UV).
Precaution: Always wear protective goggles.
- Recent Skin Procedures (Peels, Lasers, dll.)
Wait Time: 1–2 weeks post-procedure (risk of irritation). - Implanted Medical Devices
Pacemakers, insulin pumps, dll. – Theoretical risk of interference (though rare).
Precaution: Avoid direct light over the device area.
√Safe for Most People, But Monitor Reactions
Autoimmune diseases (cth., Hashimoto’s, artritis reumatoid) – No major risks reported, but start with short sessions.
Diabetes – May aid wound healing, but monitor blood sugar if using large areas.
Children – Safe under supervision, but limit session duration.
Red Flags to Stop RLT Immediately
-Skin burns, blistering, or severe redness.
-Dizziness, loya, or headaches (could indicate overuse).
-Worsening of a pre-existing condition.
How to Use RLT Safely
Patch Test – Try a small area first.
Start Slow – 5–10 mins/session, gradually increasing.
Protect Eyes – Wear amber/opaque goggles.
Check Medications – Verify if photosensitizing.
Final Advice
Apabila ragu-ragu, berunding dengan doktor (especially if you have cancer, thyroid issues, or take high-risk meds).
Choose FDA-cleared devices (cth., Merican ) for safety assurance.
