We talk about the importance of hydration a lot when the weather starts getting warmer and for good reason. It’s important to know that losing just 5-10% of your body’s water supply qualifies as moderate dehydration— which causes your blood volume and blood pressure to drop and forces your heart and respiration rates to increase as a result. This will then cause an increase in body temperature and perspiration.

If you start to experience headaches, nausea, muscle cramps, achy joints and/or general fatigue, you could have moderate dehydration, which can lead to a more serious condition if left untreated. To stay hydrated, experts recommend drinking 6-8 glasses of water each day.
