Cultivate this simple, cheap and effective habit to increase your circulation and over-all health. Here's an easy recipe to get you started!
Heat water over stove top or in a microwave-safe mug until just before a rolling boil. For microwave, about 120 seconds on high.
While water is heating juice the lemon. Use 1/2 lemon if you weigh less than 150 pounds use the whole lemon if you weigh more than 150 pounds.
Pour lemon juice into mug with hot water and stir well. Drink with the temperature as hot as possible.
You can use lime juice instead of lemon juice, if you prefer, and still retain most of the health benefits (the only question would be DNA-damage repair properties).
I like to batch-prep my lemon juice for the week. Buy a 1-pound bag of lemons for the week and juice at once. If you follow this approach you'll want to add 2 tbsp. as the equivalent for 1 whole lemon. And 1 tbsp. as the equivalent for 1/2 lemon.
Lemon or lime juice will last for 2 months (or more) when properly stored in a glass Mason jar in the fridge.
