Sputter sputter, putt putt, oof….

Is that you right now running out of gas? Are you tired all the time, don’t feel well and always run down? You probably need water! Just like cars need gas to run, our bodies need water to run properly. Without enough water, your body is breaking down.

The fact is that 75% of people are chronically dehydrated. We’re not drinking enough water. What is your go to drink that you grab each day? Maybe it’s soda, coffee, or a sugared juice. These don’t give your body the water it needs to function properly.

Our bodies are about 60% water. No kidding! Plus, our body is losing water everyday just by breathing, going to the bathroom, and sweating. And yet we struggle to drink a glass of water a day. Why? Simply because sugar and caffeine are addicting. They throw the chemical balance off in your body and make you want more of it. You need to break the habit!

I won’t get all Bill Nye the Science Guy (who is awesome by the way) on you and talk about how our cells and molecules need water, which they do! But let’s look at the basics.

1. It Helps You Lose Weight and Controls Metabolism

Who doesn’t want to boost their metabolism by up to 30%? Studies have proven this! And of course, an increase in metabolism will boost your body’s ability to burn fat. Also, if you’re drinking water, you’re not drinking sugar and calories.

2. Removes Waste Products Out of Your Body

Basically, it’s the best detox method out there! Water moves food through your intestinal tract so the waste your body doesn’t need gets removed by going to the bathroom. Water will keep your stool soft and prevent constipation.

3. Digestion and Nutrient Absorption

If you’re working hard to eat healthy, then you want your body to get those vitamins, right? Water aids in the digestion of food when we eat and that starts with saliva, which is based on water. This moves the food to the stomach, breaks down the food, and dissolves the nutrients so they can pass through your intestinal walls and into your bloodstream. Water keeps your blood from thickening and slowing down. This moves the nutrients and oxygen throughout your body better.

4. Protects Your Heart

No one wants to have a heart attack! It may be what people fear the most as they age. A 6-year study found that people who drank 5 or more glasses of water a day were less likely to die from a heart attack than those that drank 2 glasses (American Journal of Epidemiology).

5. Prevents Headaches and Other Brain Issues

This is a huge one for me because I suffer from chronic migraines, and it’s what got me to start drinking more water every day! Our brain is about 75% water… That’s huge! When we don’t drink enough water, not only is our body dehydrating, but our brain is as well. A lack of water in our brain will cause headaches, memory loss, brain fog, and sleep problems.

6. Regulates Body Temperature

The body’s cooling and heating system is distributed through perspiration. You need water so that you don’t overheat during exercise and when you’re hot. The body regulates itself through perspiration.

7. Lubricates Moving Parts

Water is a necessary lubricant for our body. It’s a lubricant and cushion for our joints and protects our spinal cord. There are studies that show water therapy has worked wonders for arthritis and fibromyalgia.

8. Cells and Other Important Stuff

Okay, we’ll briefly mention cells and science stuff since it’s important. About 75% of the water in our body is in our cells, interstitial fluid, blood plasma, lymph, and bodily sections. Water helps send electrical messages between cells so that your muscles can move, your eyes can see, your brain can think, and all that important stuff.

These are some pretty convincing facts why we should be drinking more water every day! But how much do we need? We always here, “You need to drink 8-10 glasses of water a day.” I think I’ve heard that for like 30 years LOL. That’s just a guideline to make it easy, and a good one to follow! A more accurate amount is based on your individual body weight.

To find the right amount of water to consume, a good rule of thumb is:
Your weight X 1/2 (.50) = # of ounces of water per day
Example: 150 lbs. x .50 = 75 ounces of water per day (about 9 1/2 cups of water)

Don’t let these numbers overwhelm you. 20% of our water intake comes from food each day, so you’re 20% there! 😊

There are so many benefits to drinking water! And you just flat out need it to be healthy and feel good! I personally have seen such a positive change from drinking more water, and it is a permanent part of my life now. Start choosing water and let me know the difference it makes in your life!

P.S. If you’re looking for an easy way to help you meet your water goal every day, use a timer / ounces marked water bottle. I use a 32 ounce bottle and refill at least once. Plus, it also comes with a removable filter if you want to add fruit. You can find it HERE.

Water often for health and happiness. xx

After years of chronic health problems with migraines and IBS, I began to realize drinking more water helped with many of my problems. When my mom developed Alzheimer's and osteoporosis, I decided to make a lifestyle change so that I didn't have the same future. Change isn't easy, but I hope that we can prevent chronic illness and disease by living a healthier life.


  1. Well, since reading your blog, I am on day 1 of drinking more water. I hope it makes me look as young as you do!!! I did not know about the heart attack study, that is encouraging news. I’m in it for the weight loss right now! Another great post Dayna and I subscribed. Your blog really is amazing…..I love how you did the pop ups, I have much to learn from you! You blog like a pro!

    • YAY Rosemarie, I am so happy to hear that you are inspired to drink more water! And you are too kind with the compliments. Please feel free to reach out to me anytime about blogging. I’ll be happy to help in any way I can, but I’m still learning too. I know it’s a frustrating process for sure. My email is Dayna (@) watermedaily.com or message me on Facebook. Thanks so much for subscribing! xx

  2. Thank you! This information was very interesting and clarifying. I don’t count how much water I drink daily, but I know I should… after all, a lot of times I think I’m tired or angry when I’m fact I just need water! So reaching my recommended amount would surely make a difference 🙂

    • Awe, this is so true. Lack of water really affects our mood and can make us tired and irritable. I know it happened to me for years without understanding why. So glad you can see that and work towards drinking more water. Thanks for sharing!

  3. This is really helpful. I actually got a 32 oz water bottle so I could actually see how much I was drinking. I try to bring it with me, everywhere I go & I feel the difference already. For the last week, I have noticed I have more energy and no headaches so far. I was getting headaches daily before & had no idea why. I didn’t make any other life changes, so I know it is all thanks to drinking more water. I try to drink 3 -32oz bottles a day.

    • Wow, 3 – 32o bottles a day is really great! You’re doing better than me. I need to up my water and keep up with you! I’m so glad to hear how much better you feel with the water. More water really does make a huge difference in your health and happiness. Keep drinking! Dayna xx
