Outside with wet hair

Your parents probably told you not to go outside with wet hair because you’d catch a cold. Having wet hair does not cause colds, colds are caused by a virus. There is no association of the virus with wet hair.

During below freezing temperatures, going outside with wet hair might increase the risk of hypothermia. So, if you were planning to go outside in cold weather with wet hair and without a jacket, you might want to reconsider.

Even though you do not get sick from wet hair, your hair becomes more prone to breakage in cold weather. Water expands in volume during freezing temperatures, so it forces the hair shaft to expand and lifts hair cuticles. Wet hair in freezing temperatures can be exposed to environmental damage which makes it easier for hair to get split ends.

The next time you decide to go outside in freezing temperatures with wet hair, you might want to think twice!

Stifling a sneeze

Many of us were warned as children to not hold in a sneeze, because our “heart would stop” or our “brain would explode.” While this seems like dramatic exaggeration, there may be a kernel of truth.

It might seem appropriate to pinch your nose and quiet the sneeze in certain social situations. However, recent research suggests it’s better to just let it out– while covering your mouth of course.

The diaphragm and chest muscles contract during a sneeze to clear mucus, irritants, and germs out of our system at approximately 100 miles per hour. According to ENT specialists from NYU, “suppressing the sneeze by holding the nose or mouth increases the pressure in the the sinuses, nasal cavity, or chest about 5 to 24 times of that during a normal sneeze.” Infected mucus can be pushed into the middle ear, causing infection or a ruptured eardrum. Blocking the nostril and mouth during a sneeze can also lead to air trapped in the chest, and in rare cases, the rupture of a cerebral aneurysm, a tear in the throat, or cracked cribs.

Although sneezing might seem embarrassing or unsanitary in a crowd of people, take care of your health and let your body’s natural reflexes take control. It best to sneeze or cough into the fold of your elbow.

Hot Yoga: Beneficial or Unnecessary Sweating?

Studios that offer hot yoga say that benefits include flexibility, strength, reduction of stress, and “cleansing impurities from the body”. The first 3 are available in many forms of exercise, heated or not.

The rise in popularity of hot yoga is in part due to the presumption that the heat “melts” your waistline.  Studies indicated that while hot yoga leads to a higher heart rate due to more blood vessel dilation–which makes individuals feel like they’re working harder–it doesn’t really affect the amount of calories burned. So the notion of practicing yoga in the heat primarily to lose weight is not useful.

To look at whether yoga in a hot room is healthier, a researcher compared results of participants who practiced yoga in a 105 degree room, in a 73-degree room, or did not practice yoga. The researcher assessed any changes in vascular health of these individuals by observing the amount of blood flow throughout the body. He found that there was no difference to heart health by room temperature indicating that those who did the exercises in a hot environment did not accrue anymore benefits that those who practiced yoga in room temperature setting.

Other claims asserted that the high heart rate induced by hot yoga results in a stronger heart, cleared veins, cleansed body impurities, and boosted immune system, but these claims are difficult to verify experimentally.  

For those who are new to hot yoga, or exercise in general, there is some concern regarding heat intolerance. If you decide to try hot yoga, start slow and make sure to stay hydrated. Keep in mind that the benefits of flexibility, core strength, and heart health are achieved by yoga at any temperature.
