Green Tea And Sleep Disorders

by Julian

23 May 2008 - A green tea and sleep disorders study found that its reduces conditions such as memory problems and confusion.

The study was recently published by University of Louisville researchers in the American Journal of Respiratory and Critical Care Medicine.

The animal study, led by David Gozal, professor and director of the Kosair Children's Hospital Research Institute (KCHRI), found that compounds in green tea seem to make the brain less susceptible to oxygen loss caused by sleep disordered breathing, supporting other research that suggests green tea may have therapeutic value.

"Drinking green tea may prove to be one strategy to help patients cope with the cognitive side effects of sleep disordered breathing and obstructive sleep apnea," Gozal said.

Green tea contains compounds known as green tea catechins polyphenols (GTPs). These chemicals antioxidant properties seem to protect against diseases associated with inflammation and oxidative stress damage that result from the body's interaction with oxygen although scientists don't fully understand why.

Sleep apnea is a condition in which an obstructed airway causes a person to snore as they struggle to breath and take in oxygen. Apnea, which increases oxidative stress and inflammation, has long been associated with learning and behavior problems as well as hypertension, cardiac disease and obesity.

In this study, two groups of rats were subjected to periodic oxygen depletion that mimicked the nightly breathing patterns of obstructive sleep apnea. During the two week study period, one group was given plain drinking water; the other, water laced with GTPs.

Both groups were tested for oxygen depletion and inflammation and given learning and memory tests in a water maze. The rats that drank the GTP-treated water negotiated the water maze considerably better than the other group of rats.

"This evidence supports other studies that suggest GTP may protect the brain and other organs from oxidative stress,"Gozal explained. "These novel findings clearly warrant further research."

Hi, I've been experimenting with green tea supplements("holista" brand) for weight loss for some time.

I found that for me at least that the green tea was making me tired during the day, not giving me the "caffeine boost" that others wrote about.

I've taken it before bed and not had any trouble sleeping.

This report is interesting as I think I have sleep apnea so I will try it more consistently at night to see if it helps.

It makes me sleepy too
by: Anonymous

I started drinking green tea powder with milk in the morning and noticed that it made me sleepy. I'm going to switch to drinking in at night.

Green Tea is awesome!
by: Anonymous

I have been having green tea without sugar or milk about three times a day for the last month. I have found it to be extremely helpful with my digestion as I have always had problems with digestion, bloating and acidity. and I suffer from breathing difficulties almost every winter.

But this winter i hvnt yet had any sniffles yet. But I do wake up around 3/4 am at night, which night be due to the fact that I have been very tired lately as I am not eating as much as i used to.

I do feel tired through the day, this also might be because of my changed eating habit.

I have recommended green tea to my mom and she asked me whether green tea disrupts your sleep.

There can be many reasons why mom is having sleeping problem , but overall I would take the tiredness and early mornings over indigestion any time. :)
