How does it work?

Red and near-infrared wavelengths interact with cells through photobiomodulation (PBM). Photons are absorbed by cytochrome c oxidase in the mitochondria, supporting electron transport and increasing adenosine triphosphate (ATP)—the cell’s energy currency.

This cellular effect helps:

• Promote relaxation and recovery by supporting parasympathetic (rest-and-digest) activity

• Modulate inflammatory signals that can affect mood and sleep quality

• Improve local circulation and tissue oxygenation for a calming, restorative effect

In addition, timing matters. Evening use of low-blue, red/near-infrared light can help maintain a darker, calmer environment that aligns with the body’s circadian rhythm, while daytime bright light exposure (e.g., natural daylight) reinforces alertness and a healthy sleep-wake cycle.

Applications for wellbeing

By supporting cellular energy, circulation, and nervous-system balance, light therapy complements daily routines that nurture sleep, mood, and hormonal harmony.

Common areas of application include:

• Sleep quality & wind-down
  Evening sessions with red/near-infrared light help create a soothing, low-blue environment that supports relaxation and easier sleep onset.

• Mood & stress balance
  PBM supports autonomic balance and may ease feelings of tension—useful during demanding periods or after long days.

• Cycle & hormone balance
  Regular light routines help stabilize daily rhythms that influence hormone timing. Local applications around the lower abdomen or lower back may also provide soothing comfort across the cycle.

• Energy & daytime alertness
  Morning light exposure (preferably bright natural light) reinforces the body clock, while targeted red/NIR sessions can support steady energy without stimulants.

• Seasonal transitions & routine resets
  Structured light habits help maintain consistent rhythms during travel, shift changes, or darker months.

Light therapy is non-invasive, gentle, and complementary; it pairs well with good sleep hygiene, movement, and mindful nutrition.

Key benefits at a glance

Well-timed light exposure and PBM can help the body feel settled, focused, and resilient.

Core benefits include:

• Smoother wind-down & deeper rest
  Supports evening relaxation routines and a calmer pre-sleep environment.

• Steadier mood & stress resilience
  Encourages parasympathetic tone and helps modulate stress-related signals.

• Rhythm & hormone support
  Consistent timing helps align circadian cues that influence hormone balance across the day and menstrual cycle.

• Comfort & recovery
  Improved circulation and cellular energy can ease everyday tension and foster a sense of wellbeing.

• Gentle & non-invasive
  No needles, no downtime, and easy to integrate into daily life.

Together, these effects make light therapy a valuable adjunct to sleep routines, stress-management practices, and cycle care.

Who can benefit?

Light therapy suits anyone looking to sleep better, stabilize mood, support cycle comfort, and keep daily rhythms on track—from busy professionals to travelers and shift workers.

How to use it in practice

Evening: 10–20 minutes of red/near-infrared light, about 1–2 hours before bedtime, to support relaxation and wind-down.

Morning: 5–15 minutes of bright light exposure (ideally natural daylight) soon after waking to reinforce circadian timing; optional brief red/NIR session for gentle energy.

Cycle comfort: On days with increased tension, 10–15 minutes locally (e.g., lower abdomen or lower back) can feel soothing.

Aim for 3–5 sessions per week for 4–8 weeks, then continue with a maintenance rhythm. Consistency matters more than intensity.
