Tokyo, April 29 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061406) titled 'Evaluation of the Effect of Oxygen Inhalation on Learning Efficiency' on April 28.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Open -no one is blinded Control - No treatment

Primary Sponsor: Institute - DAIKIN INDUSTRIES, LTD.

Condition: Condition - Healthy participants aged 16 to 20 years Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To investigate the effects of a high-concentration oxygen environment on learning efficiency and psychological state Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - In this study, participants inhale air with an oxygen concentration of approximately 30% using an oxygen concentrator via a headset while performing a learning task. The duration of oxygen inhalation is up to 2 hours per day. The learning task is conducted for up to approximately 9 hours per day (including breaks), during which both oxygen and ambient air conditions are applied to the same participants. The learning task consists of an English vocabulary program (1800 words), performed according to the participant's learning progress. The intervention is conducted over 3 days. Interventions/Control_2 - Under ambient air conditions, participants perform the learning task without using a headset and without oxygen supply. The learning task is conducted for up to approximately 9 hours per day (including breaks), and participants engage in an English vocabulary learning program according to their learning progress. This intervention is conducted over 3 days.

Eligibility: Age-lower limit - 16 years-old = Gender - Male and Female Key inclusion criteria - Male and female participants aged 16 to 20 years at the time of informed consent Key exclusion criteria - Individuals with a history of being diagnosed with neurological disorders Individuals diagnosed with respiratory diseases (e.g., chronic obstructive pulmonary disease, asthma), or those with symptoms suggestive of such conditions Individuals with a body mass index (BMI) greater than 28 Individuals with resting oxygen saturation (SpO2) below 94% Individuals with a resting heart rate exceeding 120 bpm Target Size - 300

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 04 Month 27 Day Anticipated trial start date - 2026 Year 04 Month 29 Day Last follow-up date - 2026 Year 05 Month 04 Day
