How to support your recovery through the season’s heat, light, and lifestyle shifts
Summer concussion recovery can feel different from other seasons. As temperatures rise and days grow longer here in Utah, many people recovering from a concussion notice a shift—sometimes in a good way, and sometimes not. The heat, longer days, and increased activity can impact symptoms like headaches, fatigue, and overstimulation.
But here’s the good news: when you understand how summer affects your recovery, you can actually use the season to your advantage.
Why Summer Impacts Your Concussion Recovery
After a brain injury, your brain may have a harder time regulating temperature, sleep, hydration, and sensory input. So naturally, the shifts that come with summer can influence your symptoms.
Here’s what changes:
Hydration demands increase, and your brain depends on water to function optimally.
Heat exposure can worsen inflammation and lead to fatigue or headaches.
A review of autonomic dysfunction post-concussion explains why heat can make symptoms worse.
More sunlight can help reset your circadian rhythm—or throw it off further.
Circadian therapy is now recognized as a key tool in acute concussion management.
Increased social and physical activity can support healing if managed well.
Sub-threshold aerobic exercise has been shown to accelerate concussion recovery.
5 Summer Strategies That Can Help You Heal Faster
At NCX Brain Recovery, we help our patients work with the season—not against it. Here are five simple shifts that can make a real difference in your healing this summer:
- Get Sunlight Early in the Day: Spending 15–20 minutes outside within your first hour of waking—ideally before 9:00 AM—helps regulate your circadian rhythm. This is important after a concussion because disrupted sleep-wake cycles are common and can slow recovery. Research shows daily morning blue light therapy improves sleep and reduces fatigue in mTBI patients.
- Create a Personal Cooling Plan: Heat sensitivity is common after a concussion and may stem from autonomic dysfunction. Try: Cool, damp cloths on your neck or wrists. Using fans directed at your feet. Staying active during cooler times of day
Here’s a review of how the autonomic nervous system is affected by concussion - Hydrate With Intention: Dehydration can worsen brain fog, fatigue, and dizziness. Your brain is about 75% water, and healing increases its metabolic demands. Aim for half your body weight in ounces of water daily, and consider adding electrolytes to improve absorption.
- Ease Into Social Situations: Summer gatherings can be loud, bright, and overstimulating—but they also offer a chance to build up your tolerance in a controlled way. Start with short, low-key visits (30–45 minutes) and listen to your body. Pacing physical and social activity has been shown to aid concussion recovery.
Let’s Talk About the Heat–Headache Connection
Many people in concussion recovery notice that their headaches become more intense or more frequent during the summer months. And it’s not just coincidence—there’s science behind why heat can worsen post-concussion symptoms.
Here’s what’s happening in your body:
Sunlight can trigger light sensitivity
Many people with concussion experience photophobia, or sensitivity to light. Brighter, longer days can strain your visual and neurological systems, triggering or worsening headaches.
Heat increases inflammation
After a concussion, your brain is already in a heightened inflammatory state. Prolonged exposure to high temperatures can compound that inflammation, making symptoms like headaches, brain fog, and fatigue worse.
Your body is working harder to cool down
Thermoregulation takes energy. When your body is trying to cool itself, it redirects blood flow and increases workload—taking resources away from recovery.
Dehydration affects brain function
Even mild dehydration can shrink brain tissue, slow down processing speed, and intensify headache pain. Since your brain is still healing, any drop in hydration can amplify your symptoms significantly.
💡 What You Can Do:
- Cool your neck, wrists, or feet during symptom flares
- Wear polarized sunglasses and a hat outdoors
- Limit time in direct sunlight, especially during peak hours (10 AM–4 PM)
- Use hydration strategies (add electrolytes or sea salt, avoid caffeine in excess)
- Pace your physical activity, especially if exercising outdoors
Even small adjustments—like shifting your walk to early morning or increasing water intake—can make a noticeable difference.
Strict Rest Isn’t Always Best
While rest is important in the early days of a concussion, complete inactivity can actually slow recovery and increase the likelihood of lingering symptoms. A team physician consensus statement published in *British Journal of Sports Medicine* found that strict rest after a sport-related concussion slows recovery and increases the probability of prolonged symptoms.
Instead, after a brief 24–48 hour rest period, clinicians now recommend gradual, progressive activity that doesn’t exacerbate symptoms. If you’re unsure what that looks like, check out our guide: What to Do If You Have a Concussion .
It outlines the most important first steps to take after a head injury—so you can avoid common pitfalls and start supporting your recovery from day one.
