Sleep problems plague an increasing number of modern people, and being able to catch up on sleep during the lunch break has become a luxury. Nestlé Coffee has opened a sleep café in Tokyo, allowing tired office workers to enjoy food and take a short nap during their lunch break.

Tea is both an everyday beverage and something that can affect rest at night. The fresh leaves of the tea plant naturally contain caffeine, a stimulant that can disrupt sleep rhythms, but tea's caffeine content is far lower than that of coffee, and it also contains components such as L-theanine that participate in relaxation and sleep regulation. Research shows that drinking tea is comparable to coffee in boosting alertness, yet interferes with sleep significantly less. In addition, herbal teas contain no caffeine, and some types, such as valerian and chamomile, have been shown to help improve sleep, while potent herbs like kava and valerian need to be used under the guidance of professionals. Only by understanding the characteristics of different types of tea can you choose the right cup to calm the mind and aid sleep, and avoid insomnia caused by improper drinking. [more…]
