Can you remember preschool when the teacher would turn down the lights and break out the cots? Nap time! You might not have had that exact experience, but as humans we are prone to napping. In our go-go-go life, time is money. To society, sleeping during the day is seen as a luxury that we cannot provide ourselves, and is usually thought of as a sign of laziness.

Unfortunately, napping doesn’t pay the bills. Even so, many physicians as well as wellness-oriented CEOs have championed the idea that a little afternoon snooze is actually beneficial, and can not only provide enough rest to fight off fatigue, but improves your alertness, improves motor learning skills, boosts memory, and enhances creativity (Soong, 2010). Can napping actually make you a better employee at work, give you better results in the gym, or enable you to have a better social life with your family and friends? Yes, in fact, it can! Here is a closer look at napping and its benefits.

What Is the Optimal Nap Length?

First, I’d like to break down naps into two parts. The duration of nap that you are taking will be specific to you, but there is information that gives a good indication that for optimal power naps, 10 to 20 minutes of sleep will provide the best results. Longer naps can make you groggy; this is known as sleep inertia (Dvorsky, 2013). The longer naps, such as a 60- to 90-minute siesta, can put you in a state of REM (otherwise known as our dream state). There are some links to cognitive function associated with longer naps, but the time frame doesn’t always work with our hectic schedules.

When Is the Best Time to Nap?

The second part deals with necessity. Our naps can be planned, in which you know you are going to need extra rest for a long night, so you take a nap. Another would be an emergency nap, where you take a nap because you otherwise would have put yourself in a dangerous situation (think about getting sleepy behind the wheel and then deciding it’s best to pull over at a rest stop for a nap). Then there is the always popular appetitive napping—in other words, taking a nap for the sheer enjoyment of it (Dvorsky, 2013).

What Are the Benefits?

Your health and wellness can benefit from a simple, short nap. At the right length, your nap can provide much-needed alertness, mental capacity, creativity, energy, reduced stress (in turn reducing the risks of heart disease), and more effective learning abilities for children. With all these positives attached to something that can be done quite simply, it’s hard to understand why anyone would not take more naps. For businesses, your employees would be better workers with higher productivity; for teachers, your students would have a better chance of learning; and for you, your overall well-being would be improved. Don’t wait; take a nap TODAY!

Many people depend on early-morning caffeine to “jump-start” their bodies. Others consume caffeinated beverages throughout the day when they are stressed or tired to keep their bodies alert and functioning. However, caffeinated foods and beverages should not replace the healthy habits of regular, balanced meals and snacks or adequate sleep.

Although caffeine provides an “energy boost,” the stimulant can also cause anxiety, restlessness, constriction of blood vessels, and an elevated heart rate. For these reasons, limit caffeine to 400mg a day.

Below are some common beverages, foods, and over-the-counter medications that contain caffeine. Caffeine content in coffee varies widely depending on the variety of coffee bean and the method of preparation used.

Caffeine Content in Milligrams (mg) for Common Foods and Medications

Coffee (8 oz.)
(The amount of ground coffee per cup is a key variable.)
Brewed: 65–120mg
Instant: 40–110mg
Decaffeinated (instant or brewed): 2–4mg
Starbucks Coffee (12 oz.): 279mg
Coffee drink with one shot of espresso (12 oz.): 113mg

Chocolate (1 oz.)
Dark: 5–35mg
Milk: 1–15mg

Cola Beverage (12 oz.)
30–60mg

Coffee/Chocolate-Flavored Dessert (1/2 cup)
Ice cream: 18–126mg
Frozen yogurt: 0–25mg

Tea (8 oz.)
Brewed: 20–90mg
(The longer it steeps, the higher the caffeine content.)
Instant: 24–31mg

Cocoa (8 oz.)
Average: 80mg

Chocolate Milk (8 oz.)
Serving: 2–8mg

Caffeine-Containing “Energy Drinks” (8.3 oz.)
Serving: 3–32mg

Caffeine-Containing “Energy Bars” (68g)
Average: 50 mg

Stimulants (per tablet)
Vivarin or NoDoz
Average: 100–200mg

Pain Relievers (per tablet)
Average: 32–65mg

Other Ways to Stay Awake During the Day

If you find yourself reaching for over 400mg of caffeine per day to stay awake and energized, try some of these healthy alternatives to caffeine:

• Do not underestimate the power of a quality night's sleep. If you generally feel well rested in the morning, you are likely meeting your slumber needs. If not, be sure to turn the TV off before falling asleep and avoid looking at bright devices that can keep your brain waves stimulated. 
• Another key is to maintain a consistent sleep/wake schedule even on the weekends.
• Exercise is another way to ensure a good night’s sleep and being more awake during the day.
• Try more natural ways to wake up.
• Finally, go outside for brief sunshine breaks. Exposure to bright light helps regulate your body's rhythms.

There are so many things in life that can affect different aspects of the human body, and stress is one of the biggest! During a stressful time in life, the body can undergo several physiological changes that can be detrimental to your overall health. Though sometimes we cannot avoid certain stressors that fall into our path of life, there are some things that can be done to help you cope during those times.

What Stress Can Do to You

Let’s take a look first at how stress affects the body.

• Sleep: Stress disturbs sleep routines, typically making it hard to fall asleep as the mind wanders, tossing and turning, and constant interrupted rest.
• Upset stomach: Another effect is having a constant feeling of being queasy or nervous.
• Loss of appetite: Along with having an upset stomach, loss of appetite comes with either consistent or high levels of stress.
• Rash: Stress can cause hives, which are a type of skin rash. Be sure during stressful times to take care of your skin by washing and moisturizing.
• Change in eye pressure: When under high amounts of stress, the pressure of your eyes can change, causing something called ocular hypertension, which affects your vision.
• Increase in blood pressure: Whether it’s short-term or long-term stress, spikes in your blood pressure can be detrimental to your overall heart health.
• Increase in resting heart rate: The number of times your heart beats per minute can increase with stress levels and cause your heart to work harder than it normally would.
• Weight loss: Excessive weight loss can come with stress as your body loses its desire to eat.
• Chronic headaches: Anxiety and stress can increase the amount of headaches you get, as well as the intensity.
• Back pain: Each person holds stress in their body in different places, oftentimes residing in the back and neck muscles, making it painful to move.
• Sweating: Stress triggers sweat glands to become more active, causing you to break out in cold sweats (like you are nervous).
• Tremors: Sudden twitches or tremors can be caused by stress, resulting in the contraction or continuous spasm of the muscles.
• Bowel issues: One way or the other, bowel issues can happen when under stress.

Overcoming Stress

Now, I know that sometimes stress is out of our control, but when those times come there is something we can do about it. Exercise is one of the proven ways to keep stress levels low. If you are feeling stressed out, try coming to the gym or fitness center to workout, run or walk, do yoga, or whatever you like to do to help you decompress.

Since the dawn of time (I’ve always wanted to start a sentence like that), humans have slept for a little while, and then were awakened by something or someone that told them it was time to start the day. We know now the huge roles that sleep plays in so many aspects of our health:

• Physical recovery
• Healthy hormonal environment
• Stress regulator
• Cognitive retention and memory
• Appetite regulation

The Science Behind Sleeping and Waking

We have circadian rhythms that act as an internal clock of sorts, which usually run on roughly a 24-hour cycle. Researchers have identified that circadian rhythms can influence our sleep-wake cycle, and abnormal circadian rhythms have been associated with obesity, diabetes, depression, and other disorders. 

Why am I telling you all this? Well, your circadian rhythms are produced by natural factors in your body, but can also be influenced by the environment. Light is the major cue influencing the rhythms that turn on or turn off genes that control your internal master clock. Having a normal, healthy circadian rhythm can be the difference between waking up ready to conquer the day or having to hit the snooze button a hundred times. 

Using Light to Wake Up

So if light is one of our biggest cues to maintain a healthy circadian rhythm, use it! My beautiful wife gave me a gift on my birthday recently that I have found to be so helpful in waking up and feeling rested and ready to go. It’s a Phillips Wake-up Light, and it allows you to wake up naturally with the warm glow of the sun-like light that radiates from this futuristic-looking alarm clock. I absolutely love it! 

The light will begin to glow anywhere from 20 to 60 minutes prior to your set time to wake up (how hard you sleep will determine how much time you should have the light begin glowing). The light begins a reddish color to simulate the sun rising, and gradually becomes brighter and brighter until you wake up and turn it off. And if you were to sleep through the 20-minute light glow, you would be awakened by birds chirping. 

I have definitely noticed a difference in my energy level when I wake up these days, as well as my attitude and mindset heading into a tough day. I was experiencing some not-so-positive reactions to my alarm clock, which really set me up for rough start to the day, which in turn affected me throughout the entire day. Now that I am waking up naturally, and not shot out of a cannon to the sound of the buzzer, the morning is much more pleasant and meaningful.

Other Benefits of Waking Up Naturally

Some other fantastic benefits of waking up naturally include the following:

• Improved insulin regulation. This is important in managing body weight and body composition.
• Improved parasympathetic response. Instead of waking up in a “fight or flight” sympathetic response, which will result in elevated resting heart rates affecting many other aspects of health, we stay in a calmer state, allowing the internal environment to adjust appropriately to stress.
• Decreased muscle tone. I am not talking about losing muscle tissue. I am referring to “turning down” the tone of certain muscle groups that can be putting you into less-than-optimal body positions. For example (and one of the most common), toned-up lats will cause you to be in extension, which can lead to lower back pain. When we are calmer, and not so jacked up, we can allow the body to tone down when needed to improve positioning and movement patterns.
• Better mood! Life is way too short to be miffed all the time, and it just causes problems in so many facets of our lives. Most of this bad mood is communicated nonverbally, which in most cases is so much stronger than anything you could say. Take my word for it, be happy in both your message and how you deliver it. This can be greatly improved if you feel good and not groggy, which started hours earlier with the whack of the snooze button. 

I highly recommend implementing some sort of a natural wake-up process that works for you. Most of us have smartphones. There are plenty of apps out there that can do the same thing as the wake-up light I describe above. Many of the newer fitness trackers such as a FitBit can also be set to gradually wake you up. Give it a try and let me know what you think, but have a back-up just in case it doesn’t work for you right away—don’t be late to work on my account!

Sleep can be a wonderful thing. Then again, when we oversleep, we sometimes feel more tired than we were when we went to bed. Is Mr. Sandman playing a prank on us, or is sleep even more of a mystery than we’re led to believe?

I enjoy my recommended 7 to 8-hour snoozes each and every night. For the average Joe and Jane, many studies link sleep deprivation to brain function, hunger control, and disease and illness prevention.

How Much Sleep Does an Athlete Need?

The question I have is, “Do athletes and individuals with higher fitness aspirations need more, less, or the same amount of sleep as everyone else?” Although not many studies have been conducted on the topic, the Gatorade Sports Science Institute published an article entitled “Sleep and the Elite Athlete” that talks about sleep deprivation in depth. 

The article is somewhat inconclusive in some areas, but it goes on to state that elite athletes can perform, but begin to decrease output at around 30 hours of deprivation. The main side effects were stated as being diminished cognitive capabilities. On a positive note, napping is encouraged for improved performance, even in sleep-deprived individuals. In summary, it’s safe to assume that athletes need and benefit from sleep and naps just like everyone else (Halson, 2014).

How Can You Get More Sleep?

You may be asking yourself, “What can I do to maximize my sleep potential?” The answers vary depending on the person. 

• Know your body and your goals. Your goals, lifestyle, and demographic (age, gender, etc.) are the major factors of your individual needs. 
• Set the right mood by ensuring your sleep sanctuary is nice and dark, and free from distractions. 
• Try not to take your pre-workout supplements two hours before bedtime (the instruction/warning label will give you exact information on the subject). For that matter, any caffeinated beverages will hinder your ability to fall asleep. 
• Start a sleep journal to chronicle your sleep behaviors. Indicate duration of sleeps and naps, moods, exercise production, and eating patterns to determine what works and what does not work for you (Halson, 2014).

You can improve your fitness results with a healthy sleep schedule along with exercise and nutrition. For more about the positive impacts of sleep, contact an HFS at NIFS to discuss a sleep game plan. Lastly, take time for a nap; all the cool kids (at least those aged 0 to 5) are doing it!

Until next time, REJOICE and EVOLVE.

Even though it’s been a few years since I graduated, it still feels like I was just walking through campus and living in the dorm. I absolutely loved college, and while many people gained the freshman 15, I took advantage of the opportunity to live on my own for the first time and make lots of healthy habits that I still follow today. Just because I created healthy habits doesn’t mean I didn’t have an amazing time.

For me, living a balanced life full of fun is essential for being healthy. Here are my top three tips for staying healthy your freshman year and beyond (that leave room for plenty of college-style fun and experiences).

1. Keep a Routine

I am a routine type of girl, but I have come to learn that having a routine is not just a “me” thing. The human body was designed to function on a schedule and to have a routine. Everyone can have a different routine, but I found that I functioned best when I went to bed a little earlier than most people and woke up a little earlier. Of course, I would stay up later on weekends to participate in events, hang out with friends, and attend socials and parties, but I would give myself a curfew (typically midnight) so that I could get some sleep and still feel great the next morning (even after having a great time the night before). The most important thing is to figure out what works for your body and stick to it. 

2. Take Advantage of the Rec/Fitness Center

Most colleges and universities have a fitness center or are affiliated with a fitness center for students to use. Guys, this is a no-brainer! Just go to the rec center or fitness center. These places offer tons of group fitness classes, personal training sessions, and weight and cardio equipment for you to do your own workouts, and they are usually open for the majority of the day. Stop making excuses; find a friend and hit up the rec/fitness center. You’ll thank me once you do!

3. Walk It Out

I went to a small university, so the farthest thing away on campus was typically a 10-minute walk. That’s it! I would only use my car if I had to take a large load somewhere or if I was leaving campus, which was very rare. Walking is amazing for the body because it gets the body moving, but it doesn’t put a lot of stress on the muscles and joints. Walking as your form of transportation is a habit that you can start during your college days and then continue throughout the rest of your life! Seriously, just walk. You’ll feel great and those freshman 15 pounds will stay far away. 

Of course, there are tons of other things you can do to stay healthy in college; these are just a few for you to start with!
