## Survey on Awareness and Consumption of Caffeine-Free Tea
On nights when you crave a warm drink before bed, have you ever hesitated, thinking, "If it has caffeine, I might not be able to sleep"?
In recent years, it has become more common to see beverages labeled "caffeine-free" or "decaf" in convenience stores and supermarkets. Against a backdrop of increasing health consciousness and interest in sleep quality, more people seem to be routinely choosing caffeine-free teas.
Therefore, in collaboration with Kenseien Co., Ltd., a specialty health tea store, we conducted a survey on "caffeine-free tea" targeting 400 men and women nationwide who had answered in a preliminary survey that they "habitually drink tea."

### 23.3% Respond That They Are "Conscious of Limiting Caffeine"
First, we asked if respondents were conscious of limiting caffeine.
As a result, 8.0% said "very conscious" and 15.3% said "somewhat conscious," totaling 23.3% who are mindful of their caffeine intake.
On the other hand, 40.5% said "not very conscious" and 36.3% said "not at all conscious," indicating that those who are not currently concerned about caffeine are the majority.
Nevertheless, it suggests that there is a certain segment of the population interested in how they manage their caffeine consumption.
### 51.6% Respond That They Limit Caffeine for "Health Reasons"
Next, we asked those who answered "conscious of limiting caffeine" about their reasons.
The most common reason was "health reasons" at 51.6%.
This was followed by "wanting to improve sleep quality" at 40.9% and "concerned about burden on the stomach" at 26.9%.
Caffeine is known as a stimulating ingredient, but its effects vary from person to person.
It appears that many people choose based on aspects directly related to their daily lives, such as sleep and stomach/intestines.
### 49.3% Respond That They "Drink Caffeine-Free Tea"
Next, we asked if respondents drink caffeine-free tea (rooibos tea, barley tea, herbal tea, etc.).
As a result, 25.8% said "often drink" and 23.5% said "sometimes drink," totaling 49.3% who incorporate caffeine-free tea into their daily lives. On the other hand, 20.0% said "rarely drink" and 30.8% said "never drink."
In addition to barley tea, which has been popular for a long time, rooibos tea and herbal teas have also become widely known in recent years. This expansion of choices is likely making caffeine-free tea more accessible.
### 51.3% Respond That They Are Satisfied with the "Impression of Being Gentle on the Body"
Next, we asked those who answered "drink caffeine-free tea" about their points of satisfaction.
The most common reason was the "impression of being gentle on the body" at 51.3%.
This was followed by "can drink without worrying about time" at 35.5% and "less likely to interfere with sleep" at 33.5%.
Other reasons included "prefer the taste" at 31.0%, "easy to relax" at 20.8%, and "easy for the whole family to drink" at 15.7%.
It is clear that the ability to drink with peace of mind during times when caffeine should be avoided, such as at night or before bedtime, as well as the taste and ease of sharing with family, are being highly valued.
