“I'm also adding a couple of drops of lemon essential oils as well. So you want to add two cups of the salt and two cups of the bicarb soda as well.”
If you didn’t realise that flying exposes you to radiation - you’re probably not alone. The major source of radiation exposure from air travel comes from the flight itself. This is because at high altitude the air gets thinner.
As explained via The Conversation: “The farther you go from the Earth’s surface, the fewer molecules of gas there are per volume of space. Thinner air thus means fewer molecules to deflect incoming cosmic rays – radiation from outer space. With less atmospheric shielding, there is more exposure to radiation.” To put this into context, the exposure from a single long-haul flight is comparable to an x-ray.
However, there’s minimal science-backed research to suggest that Rachael’s natural remedy will negate radiation exposure. However, a quick google search of the remedy returns dozens of pages dedicated to this very subject. Regardless, adding bicarb soda and some sea salt to your bath won’t do any harm so there’s no reason not to try Rachel’s bath time ritual - just make sure it’s for relaxation purposes only.
