I asked this elsewhere but I’ll ask again here: how is this any different from just going outside?

For the time periods described it's probably not significant but exposure to sunlight does increase risk of skin cancer.

  Sunlight increases the incidence of melanoma, but reduces mortality: https://www.ncbi.nlm.nih.gov/pubmed/15687362 https://www.ncbi.nlm.nih.gov/pubmed/15687362

    Interesting. Here in Australia we've had a decades-long campaign to reduce sun exposure as much as possible due to a wave of skin cancers in the '80s and '90s. It's been arguably too successful and now other health issues have become prevalent (eg. vitamin D deficiency) due to too little sun exposure. Humans evolved while being baked in the sun, it'd be surprising if eliminating sunlight almost completely didn't come with some downsides.

    That's probably due to a healthier lifestyle.

      Other studies have adjusted for the effects of BMI and exercise levels, and sun exposure is still significantly inversely associated with all cause mortality: https://onlinelibrary.wiley.com/doi/full/10.1111/joim.12251 https://onlinelibrary.wiley.com/doi/full/10.1111/joim.12251 Over a period of 20 years, you will double your risk of dying if you avoid sun exposure.

It’s easier to have a lamp at your desk than it is to work outside

  it more reminds me about sitting in front of campfire and my grandmother's house wood stove in the childhood. This is probably how i got so smart.

    That would be more far infrared than near infrared, meaning there is almost no penetration deeper than 1 millimeter or stgh.

Prof Hamblin (of Harvard) said in the video interview with the guy from selfhacked that sun at greater heights (multiple kilometers above sea level) does indeed give some of the beneficial effects that are observed with near infrared devices. Elsewhere, radiation is not strong enough to have the same effect.
