Most of the studies done on this subject indicate that 15-30 minutes of direct midday sunlight is all that humans need to maintain healthy blood levels.
Now, seasonal affective disorder is another issue entirely. That's not being significantly affected by earth houses though, as normal houses don't let a lot of sunlight in anyway.
- LtdJorge 5y agoSorry, I forgot to mention about the ever-increasing glasses problem. The perception has changed from "close distances cause myopia" to "low sunlight levels cause myopia". That's what I was talking about. Specially important with the increase in work from home jobs.
- antasvara 5y agoIs it sunlight specifically, or just low light? Either way, the amount of sunlight entering the average home is marginally more than earth homes. It would be like going from eating 300 to 100 calories a day: ultimately, the difference is negligible if neither keeps you from starving.
- LtdJorge 5y agoI guess that's true. The problem is already pretty bad (I've had glasses since I was 10 for this reason, more of a stay at home kid).
