Hydration and Cognition are Linked!

Hydration and Cognition are Linked!

We’re slowly leaving summer behind and with the cooler months we start to think less about the importance of staying hydrated. It’s just as important now as it was in July to drink water, and what it does for your body and mind is pretty amazing. 

Did you know that drinking water can actually improve your mood, memory, attention, and learning? The human brain is made primarily of water: over 75%! It makes sense that, when the body becomes dehydrated, the brain has a more difficult time doing what it needs to. 

It’s easy to lose water if you’re not consuming enough throughout your normal day. If you’re losing more water than usual because of hot weather or exercise, you’ll need to take-in even more. 

How to Stay Hydrated 

According to the Mayo Clinic, the National Academies of Sciences, Engineering, and Medicine recommends that on average, men should consume approximately 15.5 cups, or 3.7 liters, of fluid every day. For women, the recommended amount is 11.5 cups, or 2.7 liters. 

Yes, that sounds like a lot!! We’re also used to hearing that we should drink (a much more reasonable) 8 cups of water a day. However, you should take another look at that information. 

The word “consume” means you don’t necessarily need to drink the water you need. You can eat foods that contain water and still meet the recommendations. It also says “fluids,” which means you can drink a water-containing beverage like milk or juice and still get the needed H2O. 

Here are some ways to get the water you need, to keep track of your intake, and to remind you of your next water break. 

 

01.

Drink from a Marked Container 

A container that’s marked according to how much fluid it can hold is going to be your best friend. It’ll be easy to keep track of how much you’ve had to drink. For example, if you drink from a 32-ounce bottle, you can make it your goal to drink 2 or 3 of those bottles every day. This will put you at approximately 1.9- or 2.8-liters respectively. You should be able to get the rest of your water needs by eating. 

 

 02.

Eat Foods with High Water Content  

Healthline published a list of water-rich foods that can help you determine which foods to add to your day. Some great foods from this list include: 

  1. Watermelon 
  2. Cucumber 
  3. Skim Milk 
  4. Lettuce 
  5. Zucchini 
  6. Celery 
  7. Plain Yogurt 

As you can see, there’s a solid mix of sweet/salty flavors and crunchy/creamy textures. There are enough options to find at least one thing you enjoy! 

 

 03.

Use an App to Track Your Intake 

Some fitness apps have a section where you can log your water intake. Other apps exist solely for the purpose of reminding you to drink and to help you track your intake. You can simply go to your App Store from your smartphone and do a search for water tracking apps. If you just want some of our random finds, take a look at these free-to-download apps: 

Waterlogged – iOS 

Daily Water – iOS 

Water Time Pro – Android 

Drink Water – Android 

 

04.

Test Your Hydration

An easy way to tell if you’re hydrated enough is if the color of your urine is pale yellow to clear. Darker urine colors may indicate that you’re not getting enough water. There are other reasons why urine color may change so never take it strictly as a sign of dehydration!  

Another quick test is the skin elasticity test. If you pinch the skin on the top of your hand, it should quickly drop back to its original position. If it holds the pinched shape and slowly comes back down, you might be dehydrated. 

Remember that every body is different

Keep in mind that the amount of water your body requires to function healthily is going to be different from what someone else’s body requires. Even if you’re generally the same in terms of age, health, and fitness level, your body may simply need more or less. Listen to your body and focus on you!

Cholesterol and Exercise – How to Manage Your Numbers Naturally

Cholesterol and Exercise – How to Manage Your Numbers Naturally

(Evidence Based)

Does Exercise Help Manage Cholesterol?

Typically, we might hear that changing our dietary habits is the key to reducing bad cholesterol and to increasing good cholesterol. However, studies have shown that exercise also plays an important role in cholesterol management. 

Combining proper nutrition and regular exercise is the key to healthy cholesterol numbers. 

The research appears to disagree on whether the frequency or intensity of the exercise is important to improving cholesterol. However, the consensus lies in the duration of exercise.  

From Kodama and colleagues’ review of over 25 studies, all seem to agree that regular aerobic exercise, performed for a longer amount of time per session, is what will lead to improvement in overall cholesterol levels. 

What are HDLs and LDLs? 

Before we dive in, let’s take a moment to talk about some of the key terms we’ll be using. 

LDL – Low-Density Lipoprotein is what’s commonly termed “bad cholesterol.” High levels of this stuff are what put you at risk for cardiovascular complications

HDL – High-Density Lipoprotein is what we like to call “good cholesterol.” This is what carries bad cholesterol and triglycerides to the liver in order to get rid of them. 

Triglyceride – These come from the fats you consume. Like LDL, a high amount of triglyceride is also linked to cardiovascular disease

What Can Exercise Do for Cholesterol? 

A study on activity and cholesterol found that physically active individuals had lower levels of LDL and Triglyceride, and higher levels of HDL, than individuals who lived a sedentary (non-active) lifestyle. 

The levels of activity among the participants were mixed. This means that low, moderate, and high intensity exercises all made a difference. This is great news for people who are afraid to start exercising for fear they aren’t “fit enough” to exercise. If this is you, read our post on The Common Misconception of Getting Fit Before Joining a Gym

Exercises You Can You Do to Lower LDLs and Raise HDLs 

Regardless of our suggestions, you should choose an exercise that you can comfortably do for extended periods of time. It may also be necessary to have your doctor monitor how your heart responds to any new exercise routine.  

The American Heart Association recommends about 150 minutes of moderate aerobic activity per week (that’s about 30 minutes a day if you’re working out 5 days a week), or 75 minutes of vigorous activity each week.  

You can mix and match different amounts of moderate and vigorous exercise. The idea is to aim for some amount of time in the AHA’s general ballpark and work your way to a level that feels good for you.  

Aerobics

Aerobic exercises include activities like jogging, running, swimming, bicycling, dancing, and others that elevate your heart rate. 

To effect cholesterol, one study suggests that an effective level of weekly exercise is approximately 17 to 18 miles of jogging at a moderate pace. If that’s too much, 11 miles is still effective but to a lesser degree.  

If 30 minutes a day sounds a bit vague, this jogging recommendation may give you a more focused perspective on how much exercise you should aim for.  

Low to Moderate Intensity Resistance Training 

Resistance training may involve the use of objects, like dumbbells, or your own body weight to improve your muscle strength, tone, mass, or endurance. Examples include lifting free weights, bench press, deadlift, squats, lunges, and more. 

A review conducted by Mann and colleagues investigates the effects of resistance training on cholesterol. Their findings suggested that low to moderate intensity workouts were just as effective as high-intensity workouts! More good news! 

This type of exercise can be done independently to improve cholesterol or be paired with aerobic exercise. 

Conclusions

Long story short: 

  1. Regular exercise, performed for extended periods of time, is the big game changer
  2. Cardio and resistance training are shown to improve cholesterol
  3. It’s more about quality than quantity

Protect Your Skin This Summer with These 10 Tips

Protect Your Skin This Summer with These 10 Tips

Cue the Beach Boys music, grab your surfboard, and get ready for some sun-kissed skin and long summer nights!

Summer is just around the corner, and while most of us have been working hard to get beach body ready, it’s just as important to make sure our skin is summer sun-ready.

The sun’s ultraviolet (UV) rays can not only cause pain-inducing sunburns, but they can prematurely age the skin! This can leave behind wrinkles, a loss of skin elasticity, and reverse all the hard work you’ve put into maintaining a youthful appearance – but fear not. We have a solution.

10 Tips to Save Your Skin from Sun Damage

  1. Sunscreen. Yup, this is probably the most common knowledge of them all, but how do you know which SPF to use? A higher sun protection factor (SPF) (think SPF 30 and above) will generally better help prevent sunburn and protect against skin cancer.
  2. UVA vs. UVB. There are two different types of sun rays that can cause skin damage, long wave ultraviolet A (UVA) and short-wave ultraviolet B (UVB). UVA rays can penetrate deep into the skin’s thickest layer, while UVB rays usually burn the top layers of the skin. Make sure you’re using a sunscreen that protects against both UVA and UVB rays (30+).
  3. Check out your shadow. Have you heard of the Shadow Rule? If your shadow is shorter than you the sun’s rays are typically at their strongest, so you should try to find shade to avoid excess skin damage.
  4. WARNING: Did you know that some medications directly interact with direct sunlight? These medications can include certain types of antibiotics, anti-inflammatory medication, antifungals, blood pressure meds, and chemotherapy drugs. Not sure if your prescription makes the list? Check out the label on your medicine bottle. There should be a prominently displayed caution, if necessary.
  5. Cover up. We understand that you want to soak in those sweet warm rays (and hey, a tan wouldn’t be too bad either), but you may want to accessorize that bikini or swim trunks with a hat, sunglasses, or additional clothing. These extra pieces can help protect your body from damaging rays. And, don’t forget to wear sunglasses with lenses that have a high level (99% to 100%) UV protection to provide extra safety for your eyes and the surrounding skin around them.
  6. Beware water and sand. Yes, it’s summertime, so chances are you’re not going to avoid the beach altogether but be wary about too much time exposed to the water and sand. These surfaces can reflect the sun’s rays which can lead to a lobster-like sunburn. Not fun for anyone.
  7. Reapply. Sunscreen is not a one-and-done type of protection plan. For optimum protection, WebMD suggests reapplying at least every 80 minutes or sooner if you’re swimming or sweating a lot. And with the hot weather, we’re guessing you will be.
  8. Check the time. Did you know that the sun’s UVB rays are the strongest between 10AM and 4PM? Try to limit your time in the direct sunlight during these hours.
  9. Rub, don’t spray. Spray sunscreens are great, but if you don’t take the time to fully rub in the sunscreen you could be missing areas of your body that you thought you had covered. Not to mention that you may also be left with streak lines that will become noticeable if areas around the line burn from lack of sun protection.
  10. Invest in a Sun Sensor. Did you know there are sun sensors out on the market that you can easily stick onto your skin and they measure your exposure to the sun? These super helpful little stickers let you know via a connected app when you should find some shade and tracks your exposure to UV over time. Check out this article from Allure to see what they suggest.

Have fun this summer and use these tips to help protect you and your loved ones from unneeded sun damage.
