Sunlight is not optional for human health. It is how the body makes vitamin D, how the circadian clock is set, and it has a measurable effect on mood.
The skin makes vitamin D from UVB light. Deficiency is strikingly common in urban India — studies repeatedly find high rates even in sunny cities — because people work indoors, cover up, and in some cases use skin lightening products. Darker skin needs longer exposure to make the same amount.
For most people, fifteen to thirty minutes on the arms and face a few times a week, in the morning or late afternoon, is enough. Longer for darker skin. This does not require burning, and burning is exactly what causes the harm.
Morning light is the strongest signal the body has for setting its daily rhythm. Ten minutes outdoors soon after waking improves sleep that night more reliably than most things people try. This is one of the easiest and most underrated health interventions available.
The practice of looking at the sun at sunrise and sunset, associated with Hira Ratan Manek, has a following and the old site carried material on it. I want to be straightforward rather than encouraging here.
Looking directly at the sun can burn the retina. The condition is called solar retinopathy, the damage can be permanent, and — this is the dangerous part — it is painless while it happens, because the retina has no pain receptors. You do not feel the injury; you notice the blind spot afterwards.
The claims made for sun gazing, including living without food, are not supported by evidence. I describe the practice here because it is part of this tradition and readers will encounter it. I do not recommend it. If you are considering it, please speak to an ophthalmologist first.
The benefits people seek from sun gazing — light exposure, rhythm, calm, time outdoors — are all available from simply being outside at sunrise without staring at the sun.
Ayurveda holds that health follows from strong agni and that most illness begins with weak digestion producing ama, undigested residue. Whatever one makes of the theory, the practical advice that follows from it is sound: eat when hungry, make the midday meal the largest, do not eat late at night, do not eat again before the previous meal has cleared, and let the fire rest occasionally.
This site is a personal account and a record of traditional practice, shared for information. It is not medical advice, not a diagnosis, and not a treatment for any disease. I am not a doctor.
If you are unwell — and especially if you have a serious illness such as cancer, diabetes or heart disease — please stay under the care of a qualified physician. Nothing here should replace or delay that care.
