Feel tired all the time? Have no energy? Dehydration may be the cause. Our bodies are over 55% water, so even a small deficit can result in health issues. To ensure that you stay hydrated, it is important to drink at least two litres of water a day. Health benefits of water include: *more energy, *potential weight loss, *flush out toxins and *helps the body regulate temperature. Start your day with a glass of water and drink a glass every couple of hours; more often if you are outside or exercising. Raw fruits and vegetables are a great way to increase water consumption.
