## Description

desertcart.co.jp: Ultrahuman Ring AIR, No App Subscription Required, Smart Ring with Sizing Kit for Initial Fit, Tracks Sleep, Activity, Heart Rate, and Heart Rate Variability, Up to 6 Days of Battery Life (5, Aster : Sports & Outdoors

Review: 手首にウェアラブルバンドを使ってたのですが、寝てる時につけているのが嫌だったので、スマートリングにしました、軽くて付け心地もよく、今のところは気にいってます。 スマートリングのブランドとしては、海外ではそれなりに人気があるようですね。 アプリの表示項目は多くて、よくある活動量以外に回復や睡眠は細かいデータが表示されます。 睡眠改善が目的で購入したのですが、朝に振り返ると、前日の活動量や飲酒、寝た時間の影響など良かったり悪かった気付きがあります。 またPowerplugsといわれる追加機能で、睡眠に関連するようなカフェイン摂取の推奨時間帯がみれたり、日光浴の時間記録、スマホのスクリーンタイムの可視化、体内時計のリズムなどいろいろな機能があり、まだ上手く使いこなせてないですが、睡眠の質向上に活かせたらなと思ってます。 バッテリーは3日前後といった感じです、追加機能をオンにしてたり、アプリもよく見るほうだと思うので、仕事中に座ってるときに2、3日に1回充電してます。 リングの中には安いのもいろいろあるようですが、データが数値やグラフで細かく表示され、追加機能もありお値段するだけの高機能なリングだなと思ってます。月額料金がかからないのもいいですね。 睡眠改善と、回復も意識して使い続けたいなと思います。
Review: 睡眠計測だけでなく、睡眠を改善するためのカフェイン摂取、日光浴のタイミングなども教えてくれるので重宝してます！

*by T***A on March 20, 2026*

睡眠スコアと心拍変動が可視化され、睡眠改善の意識が高まりました。様々なデータを取得してくれますが、専用アプリの各項目の説明が難しいです。分からないところはAIに分析してもらっていますが、その手間が少し面倒かな。 ある程度防水対応ですが、水に触れる時は念のため外すようにしています。専用充電器の価格が高いので、お風呂や洗い物の時間を充電にあてています。
