It takes less than 5 minutes of your precious morning time. Just squeeze half a lemon in lukewarm water. If you weigh more than 150 pounds, use a whole lemon.
Why use lukewarm (or room temperature) instead of cold or hot water to make this healing morning drink? Well, hot or cold water takes more energy to process, so your first glass in the morning should be lukewarm or at room temperature to slowly wake your body and kick start digestion.
If you love the taste feel free to add more lemon water to your diet during the rest of the day, cold or hot. It adds up to your daily water need, is less boring than plain water, and adds tons of benefits for body and mind.
