In my last blog post, I wrote a little bit about the benefits of taking ice baths and cold plunges. Very similar in benefits, but on the opposite end of the spectrum, is the scorching room that is a sauna. And like the ice baths, I think there is a case to be made for incorporating saunas into your everyday routine.

What Are Saunas?

To start off, let’s talk a little bit about what exactly saunas are. Saunas are simply heated and enclosed wood-lined rooms that offer many different therapeutic benefits. Mainly they can be quite relaxing in the heat and help with sore and aching muscles as well as releasing perspiration as a way to cleanse the body of impurities.

The history and use of saunas as a therapeutic modality can be traced back to Finland. Starting in the 12th century, saunas began to appear as a log building in which rocks were heated with a fire, and the smoke was released through a small opening in the building. After the smoke cleared, one would enter the sauna and it would remain hot for about 3–4 hours. These saunas were revered by the Finnish people, and are still a big part of their culture to this day.

The Benefits of Saunas

Since saunas have been around for so long, their benefits have been studied time and time again. They have been found to relieve stress thanks in part to the release of endorphins that occurs in the heat. The heat can also help with blood flow and muscle relaxation as the blood vessels expand in the heat. Anecdotally, many have reported that saunas are instrumental in their daily routines and mental health: a place of solitude and a place to truly, deeply relax.

The Risks of Saunas

You should, however, consider the risks of sauna use. Mainly when you’re in the heat, there is a risk for blood pressure to drop. Saunas also carry a risk of dehydration due to the sweating they cause. Due to the intense heat that is present inside a sauna, limit sauna use to 10–15 minutes and drink plenty of fluids before and after.

In conclusion, there are many benefits to the use of saunas and getting in the high heat. There are many different techniques you can use and there is no right way to use a sauna—just do what you feel most comfortable with and are able to tolerate. It’s a great tool to utilize and get your sweat on!

So, if you’re like me and have been scrolling through the various social media outlets out there, you might have been seeing an uptick in a very niche fitness trend. Lately it’s all I see on TikTok, and I will admit it is intriguing watching these people on social media freeze their butts off in a cold tub of water. Often, the results are hilarious as people realize how unbearable sitting in a tub full of ice water really is. I mean look at this video and tell me whether you think this looks enjoyable. I think not, but watching these poor people suffer did have the gears turning in my mind about whether there is anything that can come out of subjecting your body to frigid temperatures, and maybe I should be partaking more regularly in these freezing experiences.

Cold Water Therapy Through the Ages

The experience of taking plunges into cold or even freezing water can be traced all the way back to nearly six millennia ago. Ice baths and cold-water immersion have been used for recovery purposes for centuries. Even as far back as 3500 B.C., the ancient Egyptian medical textbook Edwin Smith Papyrus (named for Edwin Smith, who purchased it in 1862), referring to using freezing water as a therapeutic modality. The ancient Greek physician Hippocrates in the 4th century B.C. wrote about the benefits of immersion in his work On Airs, Waters, and Places.

Looking more recently, in the 19th century, researchers looked at immersion to alleviate various ailments. Scottish physician William Cullen began prescribing cold-water therapy for patients with a wide range of symptoms including fever, inflammation, depression, and even insomnia. In the 1960s, D.H. Clark investigated cold-water immersion for post-exercise benefits. Throughout millennia and centuries, there have been numerous accounts of the benefits of immersion, both medicinal and therapeutic. But as with any modality, there is a delicate balance between the risks and the benefits.

What Are the Benefits?

Over time, a lot of work and studying has been done to investigate the benefits of cold plunges and cold-water immersion and a possible therapy for many different symptoms. There are a couple of things to consider when doing ice baths. To start, benefits of cold plunges have been studied thoroughly throughout the past couple centuries, and it has been found to reduce inflammation of sore and aching muscles, help sleep, and limit inflammatory response in the body. Anecdotally, many recreational and professional athletes swear by ice baths to help their bodies and boost their energy levels.

Know the Risks

But there are some key risks to keep in mind before plunging into freezing cold water. The biggest risk is the shock associated with plunging into cold water and the sensation that it “might take your breath away,” but a good way to combat this is focusing on breathing. Also, there is a risk for those with cardiovascular diseases as the cold water will constrict the blood vessels and create a risk for reduced blood flow. All these risks can be serious and should be discussed with a physician prior to cold-water immersion.

Something to Consider

With the introduction of cold temperatures to rehabilitate athletes and non-athletes, the benefits have proven to be significant and is something even the recreational athlete should consider.

Chances are if you are like me, you have been told your whole life, “Make sure you’re stretching, it’s important!” But to many, the first thought that pops into their head when they think about stretching is, “Why?” And that is a very understandable response because stretching can involve a lot of discomfort (in the beginning) and to some, it might even cause a bit of pain. But there certainly is a method to the madness, and a reason why stretching is a vital component of your fitness program and, ultimately, your lifestyle.

What Is Stretching?

For starters, I’ll briefly describe what stretching is. Stretching can be somewhat of an umbrella term in that a lot of day-to-day activities do in fact involve some sort of stretching to some degree. In fact, every time your muscles contract there is a stretching and a shortening occurring inside the muscle to produce force. But the type of stretching I am talking about today is more deliberate and the kind of stretching most people think of when they hear the word “stretching”; think bending over and touching your toes, for example.

Stretching is important because it is all about increasing your range of motion and flexibility in the hope that doing this can lower your risk for muscle and joint injury or strains. The better our bodies are able to move, the lower the chance is for a muscle strain or getting injured when caught in an awkward position. Stretching both statically and dynamically is known to reduce injury risk.

Types of Stretching

The main types of stretching are active, passive, dynamic, and proprioceptive neuromuscular facilitation (PNF) stretching.

• Active stretching is the main one people think of when they are told to stretch, and this type of stretching can be really good for isolating certain muscle groups. A big part of active stretching is the fact that you yourself are the one stretching out your muscles; there is no outside intervention. 
• Passive stretching is similar to active stretching in that it can be isolated to certain muscle groups, but this type normally has a partner assisting in the stretch to perhaps reach a little bit more range of motion. For example, as you can see in this picture, the person on the ground is relaxed and her partner is the one actively applying stretching force to her leg, ideally achieving more range of motion.
• Dynamic stretching is the next variation. In this type you have more of a momentum-based approach. What I mean by that is that a big part of it is using body movement and motion of the limbs themselves to achieve a change in range of motion. For example a foundational dynamic movement is high knees. This explosive movement of having knees come up as high as they can go will create range of motion throughout the legs. The foundational piece of this type of stretching is an idea of the stretch shortening cycle, which is a concept that as muscles contract and lengthen, they then shorten, and as a result are ready for activity.
• Proprioceptive neuromuscular facilitation, or PNF for short, is last but not least. PNF stretching is essentially the technique of contracting and relaxing the muscle in order to increase range of motion. The rationale behind it is that after contracting a specific muscle, the signals that lead to a muscle resisting stretching are used up, and by following up the contraction immediately with a stretch, the muscle is more likely to achieve a higher range of motion. 

Incorporate Stretching into Your Workout

After seeing these different types of stretching in more detail, the last thing to consider is, “Is this something I should incorporate into my exercise routine?” The answer is a resounding YES! Stretching has been researched and studied and has been shown to decrease the chance of injury and increase performance. So the next time you throw on your running shoes and get ready to hit the ground running (literally), take a second to do a light stretching warmup. Your body will thank you down the road (also literally)!

More and more in today’s society, people have one resource that seems like it is only getting stretched out thinner and thinner: time. Too many of us seem to be cramming more and more things into our lives, whether that be work-related events, personal interests, or family events. With this ever-growing list of things we have taking time out of our day, many have to choose between stuff they need to get done and things they want to get done. One thing we all know we should do but sometimes choose to skip because of time constraints is exercising.

Now, we all know exercising is something everybody should do. The Centers for Disease Control recommends that every adult who is able to, exercise at least 150 minutes per week, and for many it can be more. But a good amount of people fall out of this group because they simply do not have enough time to exercise.

What is a way someone can get the most efficient exercise output in as little time as possible? The possible solution could be high-intensity interval training, or HIIT (aka HIT)! HIIT is a training technique that is all about intense bursts of exercise, followed by short recovery periods. The idea behind this type of training is that with these short bursts of exercise, the heart rate can remain elevated much higher in shorter time than traditional training.

Incorporating HIIT into Your Workouts

With the definitions out of the way, we can look at just some of the ways you can incorporate HIIT training into your daily fitness lifestyle. Many people opt for the route of either aerobic or resistance-style HIIT. Aerobic is more focused on cardio and increasing cardiac output, whereas resistance has a bit more to do with working the muscles of the body with varying degrees of weight.

Now which style is the best? That depends on what your goals are. But either will be a great route to choose to try and spike that heart rate and get in a great workout without too much time commitment.

The best thing about this type of training is that it can be anything you want it to be. For example, you can elect to do a sprinting-focused workout, or biking, rowing, swimming, etc. The idea is not behind what exercise you do, but rather how you’re doing the workout.

15-minute Bodyweight HIIT Workout

Here is a simple example of an introductory HIIT workout.

3 Rounds: 45 seconds each exercise with 15 seconds of rest

1. High Knees in Place
2. Squats
3. Push-ups
4. Dips
5. Crunches

Don’t Skip Your Workout!

So the next time you are a little low on time and debating whether or not to skip a workout, high-intensity interval training could very well be the answer you’ve been looking for in order to keep up that consistency!
