Possible Clinical Benefits of Yoga

There are many myths among the general public regarding yoga. For example, some believe that yoga is only for those who are super flexible, or perhaps, only for women. I’m writing this to convince you that these myths are very false, and as it turns out yoga may hold some other lesser known benefits for its practitioners.

Yoga is a good way to improve on flexibility, it can help you with breathing as well as core strength. However, did you know that it may be able to help you lift you mood or help you sleep? A review of 16 recent studies found that yoga could help those who suffer from depression as well as those who complain of sleep problems. The studies suggested that yoga was able to influence chemical messengers in the brain, inflammation in the body, and other biological processes that influence us.

The way yoga influences our mood is by the effect it has on GABA. Low GABA levels in the body are associated with depression and other anxiety disorders. A study was performed on a group of people who regularly attended yoga classes and compared these people who went on walks instead. The study found that people who were doing yoga had higher GABA levels than those who walked, even though the two groups were burning similar amounts of calories. Also, it was found that these same people also reported a better overall mood and general well being compared to the walkers.

When hormones in the body are out of sync, many processes we take for granted can get thrown out of whack. For example, Cortisol (AKA “the stress hormone”) can have many negative effects on our body. It has been known to increase blood pressure, decrease immune function, impair cognitive function, increase abdominal fat, as well as a laundry list of other symptoms. Many of these problems can be treated by prescription pharmaceuticals. However, there is also one other widely recommended treatment for all of these problems……you guessed it, yoga!

For those of you out there looking for a new form of exercise that isn’t as high impact as running, or simply just looking to lead a healthier lifestyle, yoga could be the thing for you. It is not just the slow exercise solely for holistic women that everyone seems to think it is. It has become more popular in recent years because of its health benefits becoming known by the general public. I have recently taken to doing yoga a few times a week, and i can vouch for its efficacy. It’s a great way to get into a more healthy lifestyle for all of you out there who are falling behind on those new years resolutions.

The Perfect Nap

Have you ever wondered how long the perfect nap is?  As we are all university students I am sure that at one point or another we have had the urge to take that quick nap in an attempt to replenish our mind and body.  However, I feel that most of us have also experienced waking up from our nap feeling groggy and just plain out-of-it.  So what is the secret to a perfect nap?  It is called the power nap!

To understand the power nap we must first understand how the stages of our sleep cycle work.  Essentially, sleep comes in various stages.  In the beginning, known as the light sleep stages, you drift off as your brain slows down.  On the other hand, in later states, known as the deep sleep stages, you reach deep sleep and REM.  When we awake from the earlier stages we feel refreshed, alert and energized! This is because your brain hasn’t fully entered the sleep cycle and so waking up from it isn’t a strain on your brain. But on the other hand, if we awake during the deep sleep cycle we wake up feeling groggy and exhausted.  This is because your brain has now entered deep into the sleep cycle, thus interrupting this cycle makes you feel the opposite of refreshed.

Now you may be wondering how long of a nap this would require to avoid the deep sleep cycle.  Many studies have shown that power naps less than 30 minutes are ideal for most people in achieving optimal results when waking, as these awake you during the light sleep cycle.  For example, there was a study at the University of Düsseldorf that discovered that even naps as short as 6 to 10 minutes were able to restore memory , alertness and better learning/performance.  Additionally, the Flinders University explained through their study that a 10 minute nap was the best length for a nap in terms of recuperation.  This 10 minute length was based on the subjects only having 5 hours of sleep the night prior.

Overall, the power nap can be extremely efficient in dealing with exhaustion and a fatigued mind when done right.  It seems weird that a shorter amount of napping time will lead to better results when waking up, but we must consider how our brain functions when we sleep.  So the next time you get back from lecture and only have an hour or so before your next lecture, why not try out a quick power nap to refresh and replenish your mind and body!
