Tea that contains caffeine is a known stimulant that can interfere with sleep. However, the amount of caffeine in tea is significantly lower than in coffee, and tea contains substances other than caffeine that also have an impact on the sleep cycle.
Caffeine interferes with sleep:
Eating foods or beverages that contain caffeine late in the day can disrupt sleep and contribute to insomnia. Sleep loss can have serious effects on health and performance, with negative effects on our ability to concentrate, immune system function and creativity. The effect of caffeine varies greatly from person to person.
TIP: It is best to avoid caffeine for 4-6 hours before bedtime, and more in sensitive people and people with insomnia.
Sleep Benefits of tea compared to coffee:
One study compared coffee consumption with tea, and showed that both beverages contributed to significant increases in our alertness. However, the study also showed that tea drinkers achieved the same results and performance as coffee drinkers in improving vigiance and concentration, while green tea contains much less caffeine.
In this study, experts showed that tea consumption disrupted sleep but less significantly than coffee.
The "l-Theanine" in tea and its benefits:
Tea also contains l-Theanine which is an amino acid that turns out to play an important role in relaxation and sleep. All teas contain L-Theanine, but some types of teas, such as gyokuro, a Japanese green tea, have particularly high concentrations of this product.
Green tea and sleep apnea:
Sleep apnea is a common and potentially devastating disorder, involving pauses in breathing during sleep. This disorder often manifests itself in snoring. Although it is not common to treat snoring problems by tasting a good cup of green tea, it has been proven that antioxidants in green tea can at least prevent some of the problems caused by sleep apnea.
Tisanes for sleep:
Herbal teas come from different plants of tea, and can have very variable effects on sleep like tea. Some herbal lesans can improve sleep, while others can disturb sleep. Most herbal medicines are caffeine-free (with the exception of Mate and a few others) and are therefore very useful if you need a helping hand to fall asleep and have a good night's sleep.
