Further to nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9's comment on cell phones -

LessEMF is a odd but incredibly useful site I've been using their

products since the mid '00s for EMF Shielding.

Also - avoid headsets witih bluetooth in them. All that too close to the head can be bad in the long term. I still use old skool wired headphones for exactly this.
