Baths

Taking a hot bath or shower (or spending time in a hot room) can lead to increased body temperature and cause blood vessels to dilate, which lowers blood pressure and can cause lightheadedness or dizziness.

heating the face can make the blood vessels stand out and cause rosacea (a red rash) in those who are prone to it. The oils are dissolved more readily and stripped from the face, which means, unless you really have very oily skin, it will dry out. We now know heat ages the skin so it makes sense to avoid this type of treatment for most people.

Marshall ProtocolA curative medical treatment for chronic inflammatory disease. Based on the Marshall Pathogenesis. (MP) patients with this concern should take warm instead of hot showers or baths and try to keep the bathroom cool. Ending a warm shower with a short period of cooler water can prevent congestion in the tissues and may even relieve pain.

Hot baths can lead to increased flow of blood in all tissues of the body. Especially the tissues typically more poorly perfused by blood like nerve, joint and skin. This, in turn, can cause increased bacterial die-off and immunopathologyA temporary increase in disease symptoms experienced by Marshall Protocol patients that results from the release of cytokines and endotoxins as disease-causing bacteria are killed. due to better perfusion in all tissues of the VDR agonistA substance such as olmesartan (Benicar) or 1,25-D which activates the Vitamin D Receptor and transcribes the genes necessary for a proper innate immune response., olmesartanMedication taken regularly by patients on the Marshall Protocol for its ability to activate the Vitamin D Receptor. Also known by the trade name Benicar. .

Epsom Salts are a combination of magnesium and sulfate (MgSO₄). Research indicates that 500g (2 cups) in an average size bath for 15-20 minutes a couple times a week can modestly increase levels of both magnesium and sulfate.¹⁾ Both can be palliative during immunopathology. Magnesium can sooth sore muscles and sulfate may help with some sensitivities.²⁾

However, if you have a lot of sensitivities, or have not responded well to Epsom salt baths in the past, you may do better with a smaller amount of Epsom salts (e.g., 1/4 cup) as a starting point. Only use as much as appears beneficial. The Epsom salts may be drying to the skin.

Those with moderate to severe impairment of kidney function should exercise caution and consult one's doctor before using Epsom salts. Excessive serum magnesium can occasionally occur from the over use of Epsom salts and other magnesium-containing products in those with inadequate renal function.
