What Are 5 Benefits of Drinking Water?
1. Maintain normal blood pressure
Your body is made of about 60% water. Most of the water is inside your cells, but some is also between your cells and in your blood. The water moves between these to keep your body in balance.
When you’re dehydrated, your blood volume lowers. This means your blood grows thicker and less diluted, and the total amount of blood circulating in your body decreases. This can cause your heart rate to go up but your blood pressure to fall. Dehydration can also cause sodium (salt) levels to rise in your blood. The salts are lost through sweat, urination, and other forms of fluid loss. This can cause your blood pressure to go up.
Both low and high blood pressure are symptoms of dehydration, depending on which conditions apply most strongly. Staying hydrated can help normalize blood pressure.
2. Maintain electrolyte balance
You also have electrolytes dissolved in your blood and fluids. These include sodium, potassium, and chloride, which are all various types of salts. These keep your blood at the right pH and are necessary for your nerves and muscles to work properly.
Your body tightly regulates the balance between water and electrolytes in these fluids to keep them at the right concentration. When you don’t have enough water in your cells, your body will move salts out, to bring the water concentration. Your metabolism works almost like a balance scale. This balance has to be right for your body to function.
Your kidneys also filter extra water and electrolytes out of your blood and into your urine. If you don’t have enough water, your brain will signal your kidneys to release hormones. This tells your body to absorb more water and electrolytes, so you will urinate less.
Drinking enough water is a simple way to help keep this careful balance in check.
3. Regulate body temperature
Water also helps regulate your body temperature. It controls your temperature by dissipating heat. When your body is too hot, water moves to the skin, causing you to sweat. The sweat evaporating from your skin helps cool you down.
4. Prevent constipation
As food moves through your colon, it absorbs water and nutrients and makes waste. Your colon then contracts and pushes waste through toward your rectum for a bowel movement.
If you don’t drink enough water, food can move too slowly. The longer it stays there, the more water your colon absorbs. This can cause stool to become hard, lumpy, and difficult to move, leading to constipation. Drink water to help make sure you have regular and easy bowel movements.
5. Improve your brain
Your brain is made of about 80% water. Too little water can cause mood changes, confusion, and unclear thinking. Even mild dehydration can lower your alertness, concentration, and short-term memory. Drink enough water every day to stay sharp.
