The Scientific Method of Maintaining Concentration Without Enadori

[3: 00 PM, my head is not spinning... Is the solution really safe?]

I lose my concentration in the afternoon due to desk work. Do you have anxiety about continuing to drink energy drinks every day?

Too much sugar (more than 10 sugar cubes in one bottle)

Excessive caffeine intake (risk of insomnia, palpitations and dependence)

Heavy economic burden of 7-100,000 yen per year

The daily guilt of saying, "This is bad for your body, isn't it?"

In February 2026, the latest research at the University of Tsukuba revealed a surprising fact.

Drinking unsweetened strong carbonated water and doing 3 hours of intensive work, compared to fresh water:

・ Increase in fatigue can be suppressed

· Fun of work (motivation) is maintained

・ Reduction in judgment is mitigated

・ Improved objective fatigue index (reduction of pupil)

This was achieved with zero sugar and caffeine.

Strong carbonated water made with high pure water of RS3000 maximizes the solubility of carbon dioxide because there are no impurities. Stimulation beyond commercially available products maximizes sensory stimulation to the brain.

Personally, when I drink in the afternoon, I feel that my concentration continues until the evening. There is no "fatigue after the effect has expired" like enadori. Of course, there are individual differences in the effect.

You are freed from the health risks of enadori, and you can reduce expenses of nearly 100,000 yen per year. You can maintain your concentration without feeling guilty every day.

... Read more午後の仕事中、集中力が低下するとついエナジードリンクに手が伸びてしまう経験は多いでしょう。しかし、毎日のカフェインや糖分の過剰摂取には不安が伴います。私も以前は午後の眠気対策にエナドリを頼っていましたが、寝付きが悪くなったり動悸を感じたりすることが増え、健康面でのリスクを考えるようになりました。 そこで筑波大学の研究結果を知り、無糖の強炭酸水を取り入れてみたところ、驚くほど集中力が長持ちしました。強炭酸が口の中で刺激となり、脳を適度に刺激してくれるので午後からの疲労感が和らぎ、作業へのモチベーションが維持できました。また、瞳孔の縮小といった疲労の客観的指標も改善するという点に説得力を感じました。 私が試したのは、RS3000の高純水で作られた強炭酸水。雑味の少なさと強い炭酸の刺激が私にとってはベストフィットでした。市販の炭酸水よりも刺激的で、夕方まで頭が冴えた状態が続き、エナジードリンクのような「効果切れ後の落ち込み」もありませんでした。 経済的にも年間約7〜10万円の節約につながるのは大きいメリット。無糖なので糖分摂取を気にするストレスがなく、心理的にも安心して毎日続けられます。 私の経験から言うと、午後3時の集中力不足に悩む方は、エナジードリンクの代わりに無糖強炭酸水を試してみる価値が大いにあります。自分の体調や好みに合わせて、炭酸の強さや銘柄を変えながら継続するのがおすすめです。健康的に集中力を維持したい方の新しい選択肢として、ぜひ参考にしてみてください。
