Part 1: Medical & Health Disclaimer
1. No Doctor-Patient Relationship
Use of KeepSunshine.com, its interactive calculators (including the Morning Sunlight Duration Tool, Ultradian Sleep Cycle Planner, and 10,000 Lux Inverse-Square Calculator), or communication via email does not establish a doctor-patient, therapist-client, or other healthcare professional relationship.
2. Clinical Depression & SAD Warning
Seasonal Affective Disorder (SAD) is a recognized clinical subtype of Major Depressive Disorder (MDD). If you experience persistent sadness, hopelessness, anhedonia (loss of interest in activities), significant weight changes, or thoughts of self-harm or suicide, light therapy alone is not a substitute for comprehensive psychiatric care. Consult a board-certified physician or mental health professional immediately.

3. Bipolar Disorder & Hypomania Warning
Individuals diagnosed with or suspected of having Bipolar I or Bipolar II Disorder must exercise extreme caution with morning bright light phototherapy. Exposure to intense 10,000 Lux light can trigger hypomanic or manic episodes in susceptible individuals. Light therapy for bipolar depression must only be administered under the direct supervision of a prescribing psychiatrist.
4. Ophthalmic & Photosensitivity Precautions
Consult an ophthalmologist or optometrist before starting light therapy if you have:
- Pre-existing retinal conditions (such as macular degeneration, retinitis pigmentosa, or diabetic retinopathy)
- Glaucoma or recent cataract surgery
- Systemic conditions affecting the retina (e.g., lupus erythematosus)
- You take photosensitizing medications (including lithium, certain tetracycline antibiotics, phenothiazines, St. John's Wort, or chloroquine)
