Adding Epsom salts can make your bath more effective. This is an old home remedy for easing muscle pain which is still widely used today. It is not just an old wives’ tale – there are good reasons for thinking it will help your muscles and your headaches.
Epsom salts act as a source of magnesium ions. These play an essential role in body chemistry, including the maintenance of normal functioning of nerves and muscles.
"Epsom salts act as a source of magnesium ions… including the maintenance of normal functioning of nerves and muscles."
Many headache sufferers have lower than normal levels of magnesium ions in their blood and brain [5,6,7,8] and intravenous magnesium will often quickly relieve a headache attack.[8,9]
Magnesium ions can also enter the bloodstream by absorption across the skin [10,11]. A small study showed that soaking in an Epsom salt bath for 12 minutes two times a week should be sufficient to restore normal levels. The effects on headaches have not been studied but it seems well worth trying.
"Many headache sufferers have lower than normal levels of magnesium."
You will need about 2 cups of Epsom salts in a standard sized bath tub.
If you suffer from migraines, you may have noticed that your hands and feet tend that tend to get colder before and during an attack.
For many people this is a reliable early warning sign.
A warm bath taken at this stage will help prevent the attack from progressing further by drawing blood away from your head towards your extremities.
