Professional Athletes' Lifespan is Determined at 'Night': Launching a Research Project on the Internal Body Environment During Sleep

Toratani Co., Ltd. (Kahoku City, Ishikawa Prefecture) has newly launched the 'Night Oxygen Flow Project – Phase 2' to clarify the reality of breathing infrastructure during sleep. As its 5th installment, they are releasing the latest analysis results regarding 'hypopnea during sleep', which is at the very upstream of fatigue accumulation and performance decline.

In this analysis, we organized how daytime damage is processed at night, and how shallow breathing affects recovery, repair, and adaptation, from the perspectives of physiology, autonomic nerves, and hypoxic environments.

In the 1st installment the previous day, we showed how much thorough management and effort professional athletes accumulate. To extend an athlete's lifespan, it is necessary to eliminate 'unseen causes'.

■ However ── in reality, despite accumulating efforts, the player lifespan is surprisingly short.
If unseen causes are eliminated, physiologically, an athlete's lifespan will steadily and reliably increase.
Exclusive trainers, exclusive coaches, dietitians, medical staff, data analysis, breathing techniques, recovery, securing sleep time.

Even with all this setup, training to the limit every day, and thoroughly managing meals and sleep. Still ── the player lifespan is surprisingly short.

The true identity of this 'unfillable gap' was 'breathing during sleep'.
Only breathing during sleep is almost completely untouched. Neither trainers, coaches, nor doctors treat breathing during sleep as an 'area of expertise'.

■ It is not when awake but at 'night' that the body 'adapts'
There are physiological responses that only occur during deep sleep.
Growth hormones. Melatonin. Repair hormones. Mitochondrial regeneration. Anti-inflammatory effects.
These determine the adaptation of muscles, nerves, and metabolism. In other words, if the quality of the night is poor, no matter how much you train, you will not adapt.

■ Then, why is 'night breathing' disturbed?
Athletes suffer significant damage during the day.
High heart rate. High respiratory rate. Overexcitement of the sympathetic nerve. Chest stiffness. Respiratory muscle fatigue. Mental tension.
These remain until night, making deep breathing difficult.

★ What is even more decisive is that the 'direction of gravity changes by 90 degrees'.
No matter how much you train your muscles, your airway, thorax, and diaphragm cannot adapt to the 'change in the direction of gravity'.
When awake, gravity is vertical. When you sleep, gravity changes to 90 degrees sideways.

As a result, the airway falls backward and narrows. The thorax sinks in the direction of gravity, reducing its range of motion. The diaphragm becomes harder to lower, making it difficult for air to enter the lungs.

In other words, the physical phenomenon of sleeping posture alone inevitably makes breathing shallow.
This is a phenomenon that is structurally unavoidable for human beings, regardless of competition level or muscle strength.
And this is also an 'overlooked blind spot' in medicine and sleep science.

■ When night breathing is disturbed, recovery cannot catch up
Hypopnea during sleep causes oxygen deficiency, disturbance of autonomic nerves, decrease in deep sleep, decrease in repair hormones, and remaining inflammation.

In other words, night recovery cannot catch up with daytime damage.
This is an 'established physiological phenomenon' consistently shown across multiple areas of sleep medicine, respiratory physiology, and autonomic nervous system research.
This is the biggest reason why players' lifespans are short.

■ However ── this applies to 'all athletes'
This is the most important part.
It's just that hard sports tend to have a larger impact; hypopnea during sleep shaves off lifespan regardless of the sport's intensity.

Even in sports where breathing is less likely to be disturbed, like golf or baseball, if hypopnea continues at night, recovery will definitely be shaved off, and lifespan will quietly shorten.
In other words, what determines an athlete's lifespan is not the 'amount of effort', but the most upstream internal environment of 'how well night breathing is arranged'.

■ Diagram (Text version)
Hard sports
Large daytime damage ↓ Thoracic stiffening/sympathetic nerve persistence ↓ Airway narrows due to 90-degree gravity ↓ Hypopnea during sleep ↓ Hypoxia/lack of repair ↓ No adaptation ↓ Short player lifespan

Sports with less breathing disturbance
Small daytime load ↓ Thorax easily loosens ↓ Deep sleep ↓ Repair progresses ↓ Adaptation ↓ Long player lifespan

* However, in any sport, if hypopnea continues during sleep, lifespan will shorten.

■ Summary
Professionals thoroughly manage their breathing when awake. However, 'breathing during sleep' is completely untouched.
The body adapts at night. If night breathing is disturbed, discipline and nutrition are nullified.
The reason hard sports have short lifespans is that night recovery cannot catch up with daytime damage.
And this applies to all athletes, regardless of the intensity of the competition.
If hypopnea continues at night, recovery will definitely be shaved off, and lifespan will quietly shorten.
