Dehydration occurs when your body loses more fluids than it takes in, and it can cause symptoms such as increased thirst, dry mouth, infrequent urination, dry skin, tiredness, dizziness, and headache. The fastest way to cure dehydration is to drink fluids, particularly those that contain electrolytes, such as sports drinks or oral rehydration solutions. Here are some other ways to rehydrate your body:

• Drink water, which is the best option for rehydrating your body.
• Drink beverages high in water content, such as coconut water, which also contain salts and minerals that can replenish lost electrolytes due to diarrhea or vomiting.
• Eat fruits and vegetables, which contain high amounts of water and can help rehydrate your body.
• Eat a banana, which contains about 70% water and vital minerals such as potassium that help replenish the body.

If you are severely dehydrated, you may need to see a doctor to get treated with intravenous (IV) fluids, and severe dehydration requires immediate medical help in a hospital.
