Start your day with lots of purified water to flush out the toxins that your body has processed during the night. This gets things moving. Do you sweat during the night? That water has to be replenished.
Try to drink water at room temperature rather than ice cold as cold water shocks the stomach and increases adrenal production. Drink at least one glass upon rising before any other beverage.
To boost your immunity and help stimulate your digestive system, add the juice of half a lemon and some grated and squeezed fresh ginger. You can add a little local raw honey if it's just too sour for you first thing.
Don't drink water with meals as this dilutes your gastric juices which will slow down digestion. It's better to drink a glass or two before meals to help curb your appetite.
If you have a headache, drink a glass of water first before taking any headache remedy. Dehydration can cause headaches. Lots of purified water per day is a great way to help your body detoxify.
