Dehydration can sneak up on anyone, especially when spending time in hot weather or engaging in rigorous activities. Some of the signs of dehydration that you should look out for include: • Thirst and dry mouth - One of the most obvious signs of dehydration is feeling thirsty. Along with thirst, it’s common to notice a dry or sticky feeling in your mouth. • Dark yellow urine - Urine color is a reliable indicator of hydration status. If you notice your urine is darker or more yellow than usual, it means you’re not drinking enough fluids. • Fatigue and weakness - Dehydration can lead to symptoms such as fatigue and weakness. This happens because your body struggles to maintain blood flow and circulation without adequate fluids. • Headaches - A common symptom of dehydration is a headache. Headaches caused by dehydration can range from mild to severe and are often a result of reduced blood flow to the brain. • Dizziness and lightheadedness - When you’re dehydrated, it’s common to experience dizziness or lightheadedness, especially when standing up quickly.
