Does Green Tea Improve Sleep?


Green tea has long been celebrated for its remarkable health benefits - but can it really help you to get a better night's sleep? 

Despite green tea containing caffeine; something we’re often told to avoid when it comes to sleep, it has in fact been proven to contribute to both quality and quantity of sleep. This is because alongside caffeine, green tea is rich in antioxidants, anti-inflammatory properties, and most importantly, L-theanine. 

So what is L-theanine? 

L-theanine is an amino acid that has anxiety reducing and relaxing effects when ingested, meaning not only will you be more likely to have a stress-free day, but you’ll also have a better sleep at the end of it. 

Why is a good night’s sleep so important? 

Sleep is actually just as important for your health as diet and exercise, so whilst it can be difficult during busy work and family schedules, prioritising a good night's sleep is incredibly beneficial.

Sleeping well is sometimes easier said than done, and quality of sleep generally declines with sleep, making it even harder. That’s why small changes to your routine, such as ingesting green tea daily, can make a huge impact. 

A groundbreaking study conducted in Japan examined the effects of low-caffeine green tea on the sleep patterns of care home residents. Clear findings show that sleep quality was dramatically improved compared to when residents had higher caffeine consumption. (Unno K et al., 2017)
