Why PTSD Keeps Your System Stuck (And How to Calm Hyper Vigilance)

The lasting physical impact of trauma alters how your body processes threats. When you are looking for ways to calm hyper vigilance, you are dealing with a survival response that has been locked in the "on" position.

Common Physical Symptoms People Miss

You might notice severe muscle tension, shallow sleep, digestive issues, or being easily startled. These ongoing physical signs happen because your body is working overtime to calm hyper vigilance on its own.


Why "Just Relax" Advice Doesn't Work

When your system is stuck in fight-or-flight, your brain cannot simply choose to settle down. To calm hypervigilance, you need an environment that provides a complete, physical break from sensory triggers.


Evidence-Based Ways to Support Your Nervous System

Clinical approaches look at removing constant external inputs to help safe, long-term regulation. Giving your brain a structured, predictable space to stand down is essential to naturally calm hyper vigilance.


Hyper vigilance isn't a mindset - it's a nervous system that's learned to stay braced, often long after the danger has passed. That's why relaxation techniques that work for ordinary stress don't always touch it. The body needs a genuinely different physical state to learn it's actually safe to stand down, not just an instruction to try.


There's a growing body of research into floatation therapy and PTSD, including studies with combat veterans, showing reduced anxiety and physical tension after floating. It's not a replacement for therapy or treatment - but for some people it's a useful addition, giving the nervous system a rare, controlled experience of total stillness and safety.


This one's worth a slightly different approach than our other posts: if you're managing PTSD, it's worth mentioning it to your therapist or GP before trying, and to us when you book - we'll talk you through exactly what to expect first, including keeping the door open or the light on if that helps.

STILL NOT SURE?

Frequently Asked Questions

We understand this a new and unique experience, so please, if we have missed anything, get in touch (:

Can I float with someone at the same time?

Float therapy is intended as a personal, deeply relaxing experience, unlike a couples massage where you share the space. If you wish to come with someone, please use our Double Bookings calendar.

Can I float while pregnant?

Yes! We strongly encourage it - The water is a warm 36º, around the same temperature as your body, so the baby is safe; unlike a hot tub that is heated to 40º.

Where are you based?:

Our float therapy centre is located at 252 Central Business Park, Petherton Road, Hengrove, BS14 9BZ, inside the Fit Body Bristol gym and Bristol Martial Arts Academy. Come up the stairs, turn left and you’ll walk right past us, you can't miss us.

Swim suit or birthday suit?

We encourage floating in your birthday suit because it enhances the sensation of weightlessness and helps you fully relax. If you’d rather wear a swimsuit, that’s absolutely fine - you’ll quickly forget it’s even there during your float session.

Do I need to bring a towel?

No need to pack a towel - we provide plenty of clean towels at no extra charge. Of course, you’re welcome to bring your own if you prefer.

What if I fall asleep while floating?

Falling asleep in the float pod is common and completely safe - you’ll stay afloat thanks to the high salt content. Soon after your session ends, the pod automatically begins its cleaning cycle, which will wake you up! No one has ever slept over their session time.

How will I know when my float session is over?

Each float pod has built-in speakers that act as a timer. If you float in silence, gentle music will automatically play during the last 5 minutes. If you choose music for the full session, it will simply stop when your float ends.

Should I arrive on time?:

Please plan to arrive around 10 minutes early for your float session. This allows time for a quick introduction to the facilities, especially if it’s your first visit.

What about footwear?

We ask that outdoor shoes are left outside the float room to keep it spotless. You’re welcome to bring clean indoor shoes or simply use the Crocs we provide.

Do I have to close the pod lid?

The pod lid is optional. A few people are hesitant at first but find that once they try floating with the lid down, it feels surprisingly comfortable and not claustrophobic at all. If you’d rather keep it open, that’s absolutely fine.

Is it pitch black?

The float pod can be completely dark if you want the full sensory deprivation experience. But if you prefer, you can keep gentle coloured lights on throughout your session.

Is it silent?

You can float in complete silence or with relaxing background sounds such as spa music, waves or nature sounds. Many first-timers start with half music, half silence to ease into the experience.
