Red Light Therapy for Post Exercise Crashes
Can Red Light Therapy Help People Who Crash After Exercise? Pacing and Recovery Strategies
If you feel significantly worse after exercise rather than better, it can be confusing and discouraging. Sometimes even a short walk, light chores, or a brief workout leads to a delayed crash that can last days. This is very different from normal post workout soreness. Many people with chronic fatigue, post viral syndromes, or other complex conditions live in this pattern and wonder whether red light therapy for post exercise crashes can offer any support.
Red light therapy is not a cure for post exertional malaise or any underlying disease. It does not replace medical care, pacing strategies, or rehabilitation plans. What it may offer is gentle support for tissues and cellular energy systems, especially when you use it conservatively inside a carefully paced routine.
Why Some People Crash After Exercise
To use red light therapy wisely, it helps to understand what is different when your body crashes instead of recovering smoothly.
Normal recovery versus post exertional crashes
In typical recovery, activity causes:
-
Short term fatigue and soreness that ease within 24 to 72 hours
-
A sense of gradually feeling stronger and more capable with repeated training
-
The ability to adjust intensity without major payback
In post exertional crash patterns, even modest activity can trigger:
-
Delayed worsening of fatigue, pain, or brain fog
-
Symptoms that peak 24 to 72 hours after exertion and may last much longer
-
Reduced capacity afterward, sometimes for days or weeks
This pattern is common in conditions like myalgic encephalomyelitis or chronic fatigue syndrome and some post viral states, but can also show up with other complex chronic illnesses. It is not simply being out of shape. It reflects deeper issues in how the body handles stress and recovery.
Possible drivers under the surface
Research suggests that crashes after exertion may involve:
-
Mitochondrial stress and difficulty producing steady energy
-
Immune or inflammatory activation that ramps up after activity
-
Autonomic nervous system dysregulation that affects heart rate, blood pressure, and blood flow
-
Difficulty clearing metabolic byproducts from muscles and other tissues
No single mechanism explains every case, which is why pacing and individualized medical guidance are essential.
How Red Light Therapy Interacts With Recovery Biology
Red and near infrared light used in Biolight devices can reach tissues such as skin, muscle, and connective tissue. In research settings this is often called photobiomodulation.
Mitochondria and cellular stress
Within cells, these wavelengths have been studied for their ability to:
-
Support enzymes involved in mitochondrial energy production
-
Help cells manage oxidative stress after physical load
-
Influence signaling pathways linked to repair and inflammatory balance
For someone who crashes after exertion, these effects may help the body handle small, carefully chosen activities with less tissue level strain. This does not mean you can suddenly tolerate normal workouts. Instead, the goal is to make your current safe activity envelope a little more comfortable.
Circulation, muscle comfort, and nervous system tone
Red light therapy may also support:
-
Local microcirculation in muscles and skin
-
Muscle and joint comfort after low to moderate activity
-
A calmer nervous system state when sessions are paired with slow breathing and rest
Because nervous system overactivation can amplify fatigue and symptoms, the calming ritual of Biolight sessions can be as important as the light itself.
Pacing Comes First: Building A Safer Activity Framework
Before thinking about red light therapy for post exercise crashes, it is crucial to focus on pacing.
What pacing really means
Pacing is the art of:
-
Staying below the threshold that triggers crashes
-
Breaking tasks into smaller chunks with intentional rest
-
Planning your day to avoid big spikes of physical, cognitive, or emotional effort
It often includes:
-
Using timers or heart rate monitors as guides, if your clinician recommends them
-
Alternating activity and rest rather than pushing until you fall apart
-
Accepting that smaller, consistent efforts are safer than occasional big pushes
Red light therapy can support this process, but it cannot replace it. If you continue to overshoot your limits, no light device will prevent crashes.
Identifying your current baseline
With guidance from your healthcare professional, start by asking:
-
What level of activity can I usually do on my better days without triggering a crash
-
What combination of physical, mental, and social tasks tends to tip me over
-
How much genuine rest do I build into my day
This baseline becomes the foundation on which you layer both pacing strategies and any supportive tools like Biolight.
Integrating Biolight Into Pacing And Recovery
Once pacing is in place, you can consider where Biolight might reasonably fit. The key is to keep doses small at first and to treat red light therapy itself as a load on your system, not just a free benefit.
Start low, go slow
A cautious starting pattern might be:
-
Two or three Biolight sessions per week
-
Five to ten minutes per session at the recommended distance
-
Exposure to one or two body regions such as legs or torso, not the entire body at once
Track how you feel for 24 to 72 hours after each session, just as you would after an activity. If you notice clear worsening of symptoms that correlate with sessions, that may mean the dose is too high or that light therapy is not appropriate for you at this stage.
Use red light around, not instead of, rest
For people who crash after exercise, Biolight often fits best:
-
During planned rest periods after small activities, such as a short walk or light household task
-
On days when you are recovering from a slightly higher load, with your clinician’s approval
-
As part of an evening wind down routine to support relaxation and sleep
Avoid using red light therapy as a way to push harder. If you consistently do more because you feel a bit better, you may still trigger crashes that undo any benefits.
Combine sessions with nervous system calming
To get more from each session with minimal extra load, pair Biolight with:
-
Slow, relaxed breathing with longer exhale than inhale
-
Gentle body scanning or mindfulness to notice tension without judging it
-
Quiet audio or silence rather than engaging content that demands attention
This helps align cellular support from the light with nervous system regulation, which is a major part of recovery in crash prone bodies.
Practical Recovery Strategies Around Activity
Biolight is part of a broader toolkit for people who crash after exertion. Other pieces, chosen with your clinician, often include:
Pre activity strategies
-
Planning tasks for times of day when you tend to have more capacity
-
Warming up with very gentle movements rather than jumping into effort
-
Hydrating and, if appropriate, having a light snack to avoid energy dips
Biolight is not usually the first step before activity in very sensitive individuals, but as you stabilize, you may experiment with short sessions earlier in the day if your clinician agrees.
Post activity strategies
After any planned effort, even small, build in:
-
Immediate rest in a comfortable position
-
Hydration and, if tolerated, light refueling
-
Optional short Biolight session if past experience suggests it helps you feel more comfortable
The goal is to interrupt the pattern where activity snowballs into escalating stress signals.
Safety, Medical Oversight, And Clear Boundaries
Because crash patterns are often tied to complex conditions, medical guidance is critical. You should consult a qualified healthcare professional before using Biolight if you:
-
Have been diagnosed with myalgic encephalomyelitis, chronic fatigue syndrome, or complex post viral conditions
-
Experience significant autonomic instability, such as frequent near fainting, extreme heart rate swings, or major blood pressure drops
-
Take medications that increase light sensitivity
-
Have a history of skin cancers or significant skin disease in areas you want to expose
Even with approval, stay alert for signs that light exposure is too much, such as new or clearly worsened crashes that correlate with sessions.
Key Takeaway
For people who crash after exercise, the central pillars are pacing, energy conservation, and medical guidance. Red light therapy for post exercise crashes is best understood as a gentle adjunct that may support mitochondrial function, tissue comfort, and nervous system calming when used at conservative doses inside a well paced routine.
Biolight cannot prevent crashes if you regularly exceed your limits, and it cannot cure the underlying condition. What it can sometimes do is make small, carefully chosen activities more tolerable and recovery periods more comfortable, which can improve quality of life when combined with thoughtful pacing and clinical care.
FAQ
Can red light therapy stop post exertional malaise from happening?
No. Red light therapy does not stop post exertional malaise or cure the conditions that cause it. At best, it may help support comfort and recovery around carefully paced activity. Preventing crashes still depends on strict pacing and respecting your current limits.
Should I use red light therapy on the days when I feel worst after a crash?
Some people prefer to avoid new inputs on their worst days and focus on rest only. Others find that very short, gentle Biolight sessions on crash days feel soothing. The right approach is highly individual and should be decided with your clinician. If sessions seem to prolong or deepen crashes, it is important to stop and reassess.
Is red light therapy safe if I have a diagnosis like ME or chronic fatigue syndrome?
Many people with these diagnoses use red light therapy cautiously, but safety depends on your specific situation, sensitivity level, medications, and skin health. Always talk with a healthcare professional who understands your condition before starting, and begin with very low doses while tracking your response over several days after each session.
