Why we started this

We have seen athletes invest heavily in training, structure, and marginal gains, while recovery is often left inconsistent.

The result is not a lack of effort, but a mismatch. High input on one side, insufficient recovery on the other.

Sleep remains the primary driver of recovery. It governs adaptation, hormonal balance, cognitive function, and long-term performance.

Yet in modern environments, sleep is no longer determined by biology alone. Artificial light extends the day, often without awareness of its impact.

PHASE¹ was built to address this gap.

Not by adding complexity, but by removing a key disruption — allowing recovery to function as it should.

What is blue light

Blue light is a short-wavelength, high-energy portion of the visible light spectrum, typically between 460 and 480 nanometres.

During the day, it plays a functional role. Exposure to natural blue light supports alertness, reaction time, and cognitive performance.

The issue is not blue light itself, but exposure at the wrong time.

Artificial sources — including screens and LED lighting — emit significant levels of blue light well into the evening, extending biological daytime beyond natural limits.

How it affects sleep and recovery

The circadian rhythm is regulated by the brain’s internal clock, which relies on light signals to determine sleep timing.

Blue light has a disproportionate effect because it directly stimulates melanopsin-containing retinal cells, suppressing melatonin production.

Evening exposure has been shown to delay sleep onset, reduce total sleep duration, and decrease slow-wave sleep — the phase most associated with physical recovery.

For athletes, this is not negligible.

Disrupted sleep affects glycogen restoration, hormonal regulation, neuromuscular recovery, and next-day performance.

Controlling the variable

In an ideal setting, light exposure would naturally decrease after sunset.

In practice, this is rarely the case.

Evening routines often include screens, analysis, communication, or simply time spent indoors under artificial lighting.

PHASE¹ blue light blocking glasses are designed to reduce the wavelengths that interfere with melatonin production during these periods.

They do not replace good sleep habits.

They act as a targeted intervention when conditions are not optimal — preserving circadian alignment while maintaining functional vision.
