The Impact of Air Conditioning on Health

Q:
During the hot days of summer, is spending too much time in air conditioned buildings bad for your health?

A:
Numerous institutions and scholars list air conditioning as one of the greatest achievements of the 20th century.  They are widely used in westernized countries and global use is growing rapidly, but is it bad for you?

Below are the common positives and negatives impacts on health:

         Positive: Combat heat related illnesses (heat stroke). According to the Centers for Disease Control and Prevention, air conditioning is the number one protective factor against heat-related illness and death.  Age groups most susceptible are children under 4 and adults over 65.

         Positive: Helps manage allergies and asthma. Air conditioning can help filter out airborne pollen.  It also lowers indoor humidity, which in-turn decreases the growth of dust mites or mold.

         Negative: Mold and fungus. If regular maintenance and air filter changes do not occur, air conditioning can be a breeding ground for bacteria and fungus due to the moisture that accumulates in the evaporator coils.

         Negative: Weather acclimation/exercise.  Never venturing out in hot weather will prevent acclimation to the heat thus causing us to stay inside even more.  The more time spent inside the more likely the person is to be sedentary.

Blood Thinners

Q: 
How do “blood thinners” reduce blood viscosity?

A: 
Blood Thinners have no impact on the viscosity (thickness) of blood.  Instead, blood thinners prevent the blood from clotting or existing clots from getting larger.  They do not dissolve existing clots.

Blood thinners fall into two categories:  anticoagulants and antiplatelets. Anticoagulants, such as heparin, lengthen the time it takes to form a clot.  Antiplatelets, such as aspirin, prevent blood cells called platelets from clumping together to form a clot.

Blood thinners are prescribed to treat some types of heart disease, to those with a higher risk of stroke, or a higher risk of clotting. 

Although beneficial, blood thinners may increase the risk of serious bleeding due to cuts or injuries.  Our first line of defense should be proper nutrition and exercise to combat diseases.

Burning Sensation in Lungs During Exercise

Q:
What causes my lungs to have a burning sensation during exercise?

A:
At some point in our lives, we all have experienced a burning sensation in our lungs or airway while we were exercising.  What causes this feeling?
         Fitness level/activity intensity - If you are new to exercise, coming off a layoff, or increasing the activity’s intensity level you will tax your respiratory system.  When you tax your respiratory system, you breathe through your mouth and not your nose.  Mouth breathing will dry the mucus membranes and can result in a burning sensation.

         Air temperature/dry air - Cold air can be uncomfortable, but the air is warmed to body temperature before it reaches the lungs.  The burning sensation when exercising in cold temperatures is due to the fact that cold temperatures have dry air.  Dry air aggravates the lungs and airway and can lead to a burning sensation.

         Illness - Acute conditions that originate in or affect the lungs or airways (bronchitis, pneumonia) have a burning sensation associated with the illness.  Exercise may intensify the feeling.

         Environmental – Exercising in an environment heavy in irritants or pollutants will have a negative impact on the respiratory system and may lead to a burning sensation.

         Chronic Respiratory Disease – Chronic diseases, such as exercise-induced asthma, result in the airway constricting during exercise and can lead to a burning sensation.

WebMD Magazine "Training Day" Article


The June 2016 issue of WedMD magazine published an article by Kara Mayer Robinson in its “Living Healthy” section highlighting the importance of adding weekly strength training to your exercise regimen.  Not only does the article touch on important benefits of strength training, such as increased muscle and bone strength, improved posture, reduction to the likelihood of injury, and improved metabolism, but it also provides a solid list of recommendations for optimizing your results.  The purpose of this post is to provide a summary of these recommendations, as many of them fall in line with the training philosophies here at Fitness First. 

Target Every Zone- In order to reduce the likelihood of muscle imbalances and posture problems, it is important to aim for two to three strength training sessions a week targeting every muscle group.  This will ensure proper muscle symmetry and balance, as well as provide attention to any muscle groups that may be lacking. 

Focus on Form- At no point during an exercise should form be compromised to achieve more repetitions.  Fitness First focuses on the importance of quality movements as opposed to focusing on the quantity of movements.  This ensures a safe, efficient, and effective approach to strength training.

Add Weight Without Compromising Form- Progression is an importance aspect of achieving your desired results from strength training.  An appropriate resistance should be utilized for every activity until a desired repetition range can be achieved without compromising form.  Adding resistance gradually and sensibly is a good rule of thumb.

Take Time Off- Strength training causes micro-trauma to muscle tissue and it requires rest and recovery to repair itself.  This tearing of the muscle tissue and repairing process is what leads to increases in muscle strength.  Aim for at least 48 hours betweens training sessions. 

Don’t Hold Your Breath- It is important to maintain a normal breathing pattern as you perform any strength training exercise.  This will help ensure optimal delivery of oxygenated blood to the muscles during activity.  It also helps reduce issues related to hyperventilation, which can lead to the premature termination of an exercise due to central nervous system defense mechanisms. 

Don’t Go Fast- We’ve been saying this all along at Fitness First! This article gets it right by saying that slow, controlled movements are better, no matter the type of resistance being used.

Don’t Quit Too Soon- The article hits the nail on the head with this tip.  Performing repetitions until you cant do any more with good form is imperative for maximizing a training session.  Training to “failure” or fatigue means an adequate stimulus has been provided to the muscle tissue for it to adapt, rebuild, and ultimately get stronger.  That is the purpose of strength training, right?

Don’t Fall Into a Rut- Mixing things up periodically is important to navigate around boredom and burnout during exercise.  It is easy to create habits, but eventually new challenges are needed both physically and mentally.  At Fitness First, we address this by alternating workouts so that not every session is exactly the same.  After 20 sessions, we redesign a client’s exercise prescription, providing variety with equipment, activities, and overload protocols.  We take input from the client for activity selection and use our expertise to design routines that provide a comprehensive approach to total-body strength training.

The WedMD magazine article highlights many important strength training recommendations.  The bolded points above are cornerstones to the training philosophy at Fitness First.  All of these guidelines form a foundation for training safely, efficiently, and effectively.

June is National Dairy Month

June is National Dairy Month!

"National Dairy Month is a great way to start the summer with nutrient-rich dairy foods. From calcium to potassium, dairy products like milk contain nine essential nutrients which may help to better manage your weight, reduce your risk for high blood pressure, osteoporosis and certain cancers. Whether it's protein to help build and repair the muscle tissue of active bodies or vitamin A to help maintain healthy skin, dairy products are a natural nutrient powerhouse. Those are just a few of the reasons that you should celebrate dairy not just in June, but all year long."
-International Dairy Foods Association


Are you aware of these other dairy facts?
1. An eight-ounce glass of milk, one-ounce of most cheeses and an eight-ounce container of yogurt have as much protein as one egg.
2. Yogurt contains live and active cultures, or probiotics. Probiotics can help maintain a healthy digestive system.
3. Cheese contributes high-quality protein as well as calcium, phosphorus and vitamin A to the diet.
Now that you know, kick off your summer with nutrient-rich dairy foods and put your new knowledge to work for your health!

Fitness Level and Sweating

Q:
How does fitness level impact the amount that a person will sweat?

A:
There are a number of factors that determine how much sweat a person will produce.  Some of these factors include:  gender, body composition, number of sweat glands, skin surface area, environmental conditions, and genetics.

Another factor is fitness level.  People that are in better shape are capable of sweating more and generally do.  The reason people in better shape are capable of sweating more is due to the fact that their higher fitness level allows them to do more physical work.

The more work you do, the more heat your body generates, and the more sweat you will produce to regulate body temperature.

Facial, Mouth, and Head Injuries

Q:  Why is spring considered the worst time of the year for facial, mouth, and head injuries?

A:  Spring is the worst time of year for these injuries.  As a matter of fact, April is National Facial Protection Month.  April was named National Facial Protection month and is sponsored by several Sport and Dental associations due to the large number of injuries from people getting outside and participating in outdoor activities.

Research by the American Academy of Pediatric Dentistry’s Policy on Prevention of Sports-related Orofacial Injuries found that 10% to 39% of all dental injuries in children are related to sport injuries. Research also found that three of the five most common causes of childhood injuries are bicycling, playgrounds and soccer.

Most of the injuries could have been prevented or minimized by following the below guidelines:

        Use a mouth guard to protect your teeth.
        Wear a helmet.  Not just for sports like football or hockey.  Wear when playing sports such as softball, baseball, bicycling, and skateboarding.
        Ensure for proper vision (20/20) and wear protective eye gear.
        Use face shields to protect your face from flying objects and balls.
        Be alert.  Be conscience of your surroundings and minimize distractions.
