I keep hearing this nonsense about doing exercise in a hot room such as yoga. I am finding that the general public is very misinformed about human physiology and how our bodies react to exercising in hot climates. This is the first part of a 2 part article designed to give people some important information about what is exactly happening to their bodies when they attend these hot workouts, and how they may even be increasing their risk of heat exhaustion and heat stroke. I will also attempt to show you how many of the claims are completely false.

This is a short list of the most persistent claims I typically found about hot yoga on the internet.

Increased heat of the room allows for better flexibility and stretching

Increased heart rate allows your body to more easily burn fat and gives a cardiovascular workout

Increased Sweating helps your body eliminate toxins

Lets look at each one of these in more detail from a scientific standpoint.

Increased Temperature means increased flexibility
Increased core body temperature of approximately 3 degrees has been shown scientifically to be the threshold where connective tissues like ligaments, tendons and muscles become more elastic and flexible. This temperature increase has been shown to be possible with exercise. For example 20 minutes of cardio such as running or biking can get your core temperature up enough. External heat like heat patches applied directly to muscles have been shown to be ineffective at increasing the temperature of these tissues. If these hot workouts provide an increase in flexibility I have yet to find research to substantiate it. But if you like the way it feels I cant argue with anyone on that point.

Increased Heart Rate means increased fat burning and cardio fitness
The increase in heart rate you get from exercising in the heat is a result of excessive fluid loss from profuse sweating. The heart has to pump more often because there is less blood volume per beat. This is an early sign of dehydration. This has nothing to do with fat burning or cardiovascular fitness. This will also cause you to fatigue prematurely and cause your body core temperature to heat up even more as now your heart is working even harder. This starts a vicious cycle of increasing body temperature and sets you on a path to heat illness or heat exhaustion.

Excessive sweating causes you to sweat out toxins
Sweat does not remove toxins, this is a complete lie with no scientific proof at all. The only potential way sweat could be used for detox is rehab from drug addiction if at all. In these cases the rehab should be under the supervision of a medical practitioner, and even this is very poorly represented in the scientific research and mostly shows up in alternative medicine articles. Sweating in hot environments is your bodies way of cooling down through evaporation of water. In a humid room the sweat is much less effective at cooling your body down. Toweling the sweat off also interferes with the ability of the sweat to cool your body off. If the room is humid (and from what I am reading hot yoga rooms are meant to be at approximately 50% humidity) the sweat is even less effective at cooling you off. This starts a vicious cycle of your body temperature increasing, then your body sweats more to try and cool you off, and then you become more dehydrated. This is also a dangerous situation if you stay in the heat for too long. All of this extra sweating is just a recipe for dehydration and heat exhaustion. There is simply no such thing as sweating out toxins. This is an idea that has been laid to rest by the scientific medical community decades ago. The fact that it still persists in pop culture is absolutely ridiculous.

Part 2 of this article will explain heat acclimatization, why I think this hot workout trend is simply a marketing angle, and some of the real benefits of yoga.

Tattoos are the perfect way for anyone to express themselves. The possibilities are in no way limited when it comes to decorating your body with permanent ink. Whether you are into tattoo by hobby or are looking to make it your profession, you have the need for good, quality tattoo starter kits. This article will tell you what to look for.

When you are first getting into being a tattoo artist on a personal and hobby-related level, purchasing the right equipment might seem daunting. A tattoo starter kit is the best way to get all the tattoo equipment you need without spending too much money. A good tattoo starter kit should include a tattoo machine, needles, tubs and tattoo ink. Make sure your tattoo machine comes with the right power supply as well.

In addition to the basics, when you look into purchasing tattoo starter kits, see what kinds of extra equipment are included. Many companies will include the smaller necessary items like gloves and rubber bands. And if youre really lucky, youll find a tattoo starter kit that includes design sheets. These sheets offer a great starting point for your tattooing with popular tattoo art to choose from.

Whether you are just starting to apprentice or you own your own tattoo parlor, tattoo starter kits are necessary to keep business going. A new tattoo apprentice should look for a starter kit that offers a lot of extras, including stencil paper and tip guides. On the other hand, a seasoned tattoo professional might be looking for a more basic starter kit to replace one that is out of date or to supply their tattoo parlor with new equipment. Both kinds of tattoo starter kits are available.

When cyclists talk about cadence they are referring to the number of revolutions that they crank makes each minute as the pedals are turned. This in laymans terms simply is the speed at which the cyclist pedals or turns the pedals on the bike as they ride.

Most cyclists will have a certain cadence speed which they feel comfortable with when they are out riding. Today a lot of bicycles come with a large number of gears so it makes it possible for a cyclist to stick to a cadence that they prefer through a wide range of different speeds at which they are traveling. Normally a typical cyclist will look at having a cadence of between 60 and 80 revs per minute (rpm), whilst professional (racing) cyclists will look at theirs being between 80 and 120 rpm. However sprint cyclists will normally be able to manage 170 rpm for very short distances. Lance Armstrong one of the worlds well known professional cyclists is able to produce a cadence of 120 rpm.

However there are many cyclists that believe one form of cadence is much more efficient than another. but the actual cadence that is preferred by each rider is completely different. Yet with racing cyclists the differences in their preferred cadences are very small compared to those people who just enjoy cycling for pleasure rather than as a competitive sport.

What is important to note that each cyclist will have his own particular range of cadences that he prefers and are much smaller than the general ranges which have been previously listed above? but what their preferred cadences are will actually influence the number as well as the range of gears that they have on their bicycle and which they feel are appropriate for the conditions in which they ride.

Today there are many companys who produce devices for measuring the cadence on a persons bicycle such as the Vetta V100 wireless cadence kit. These small computers are mounted on to the handlebars of the users bicycle and then a small magnet is placed close to the pedal sprocket. Then as the rider is out cycling or competing in a race they will see on the small computer screen (which is mounted to the handlebars) displays their cadence information.

Technologies exist to possibly downgrade hurricane and tornado strength, reducing the damages created by these natural events, benefiting everyone regardless of sex, national origin, religious beliefs, political affiliation, sexual preference or any other issue.

These technologies have been developed for different purposes, they are very powerful, yet, environmentally friendly. The Governors of the gulf and MidWest states have been informed of these and...NONE CARE. It is not necessary to re-invent the wheel, just re-direct these and evaluate their results.

hurricanes and Tornadoes are basically the same phenomenon, at a point and place in time, atmospheric pressure starts dropping, at the same time, wind speed increases and " things " are sucked, such as water, trees, vehicles and many other items due to a " vacuum " effect created by nature, we as human beings, have developed the..." vacuum cleaner ".

There are two technologies which could counter these effects.

No. 1, aims to counter the pressure drop by creating pressure inside the vortex and a hole on the wall.

No. 2, aims to destroy the vacuum created by punching a hole in the vortex wall.

In either case, vacuum is lost and the natural event would revert to just a storm. This project will entail involvement by private industry, state and federal governments.

We have the money and the resources. Together we can make a difference including saving lives. If interested, please, let me know; the time has come to accept that we can do better.
