في حين أن أسرة العلاج بالضوء الأحمر آمنة بشكل عام لمعظم الناس, بعض الظروف والمواقف قد تشكل مخاطر. فيما يلي قائمة مفصلة بموانع الاستعمال (متى يجب تجنب RLT) والاحتياطات الواجب مراعاتها.
موانع مطلقة (تجنب تماما)
- Active Cancer or Tumor Risk
لماذا? Red/NIR light may stimulate cellular activity, theoretically promoting cancer cell growth.
استثناء: تستخدم بعض العيادات RLT تحت إشراف طبي لعلاج الآثار الجانبية المرتبطة بالسرطان (على سبيل المثال, التهاب الغشاء المخاطي للفم).
- الحمل
لماذا? Limited research on fetal safety; potential risk of overheating (if combined with heat-based therapies).
بديل: Use only on small areas (على سبيل المثال, وجه, الأيدي) after consulting a doctor.
- Photosensitivity Disorders
Conditions: مرض الذئبة, porphyria, xeroderma pigmentosum.
لماذا? Abnormal skin reactions to light, leading to rashes or burns.
- Use of Photosensitizing Medications
Drugs to Watch For:
المضادات الحيوية (tetracyclines, ciprofloxacin).
الرتينوئيدات (اكوتاني, tretinoin).
Chemotherapy drugs (5-FU, methotrexate).
لماذا? Increased risk of burns or hyperpigmentation.
Relative Contraindications (Use with Caution or Medical Approval)
- Thyroid Disorders
Concern: بالقرب من الأشعة تحت الحمراء (نير) light may temporarily affect thyroid function (especially hyperthyroidism).
Precaution: Limit neck exposure; monitor symptoms.
- Epilepsy or Seizure Disorders
لماذا? Bright, flashing lights (in some devices) could trigger seizures.
Solution: Use steady, non-pulsing light settings.
- Eye Conditions
مخاطرة: Retinal damage from prolonged direct exposure (though RLT lacks UV).
Precaution: Always wear protective goggles.
- Recent Skin Procedures (Peels, Lasers, إلخ.)
Wait Time: 1–2 weeks post-procedure (risk of irritation). - Implanted Medical Devices
Pacemakers, insulin pumps, إلخ. – Theoretical risk of interference (though rare).
Precaution: Avoid direct light over the device area.
√Safe for Most People, But Monitor Reactions
Autoimmune diseases (على سبيل المثال, Hashimoto’s, التهاب المفصل الروماتويدي) – 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.
-دوخة, غثيان, 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
عندما تكون في شك, consult a doctor (especially if you have cancer, thyroid issues, or take high-risk meds).
Choose FDA-cleared devices (على سبيل المثال, أمريكي ) for safety assurance.
