Cold Exposure for Hooding to Reduce UEE? (looking at an old thread)

[recessed_monkey]

I was looking through some old threads, and I came across this: Hoodingmaxxing/CTmaxxing 101.

TLDR, it says that exposing your face to cold (ice/cold water) will force your body to increase brown fat, and increase the fat above your eye. What does everyone thing about this?

His before and after (2 months apart):

As you can see, marginal decease in UEE.

Any negative side affects from this? This thread is from 6 years ago, too.
