Description:
Everything you need to know about the sleep-regulating hormone melatonin! We've always been told maintaining a healthy sleep cycle is of utmost importance to your day-to-day health. But have we ever been told why?
Anyone familiar with chronobiology (the science of natural physiological rhythms) knows that the hormone melatonin is the foundation hormone for the circadian rhythm research. In fact, melatonin and sleep research is one of the most fundamental and best-known rhythms in the human body. Disturbance of the melatonin cycle due to any reason interferes with the sleep/wake cycle, which ultimately leads to a number of other neurobehavioral and psychological problems.
Due to the widespread misuse of light at night, modern societies no longer hold a clear distinction between day and night. This increase in light pollution at night interferes with the ability of the pineal gland to produce and disperse melatonin properly. As a result, either no or a severely dampened melatonin rhythm exists in individuals exposed to artificial light during the normal dark hours, which includes most people living in cities and in all individuals who work at night. This suppression of a distinct melatonin rhythm and all other biological cycles represents a serious perturbation of the biological clock of many organs, contributing to pathophysiology.
Dr. Fauteck also addresses the impact of proper supplemental melatonin and various studies and research done on the topic. Melatonin has been
widely used to correct problems of sleep disorders, and while this book looks into that research further and breaks down the impact of melatonin and sleep,

Best jiggle balls we have found thus far
Color: Ripple Pattern
Yes ! First off this was a great value for the money. The balls function just as described and they have a decent battery life. They entertain both our goldens for a good bit of time. They have so far held up and not been chewed up . We limit the time and put them away after that time.. to avoid them being destroyed. Of all the jiggle balls we have purchased these are by far the best. The way the component is encased in the rubber protects it.. and it screws together very well. I am so pleased with these !

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs.
The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily.
Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.
