POTS, But Make It Livable

What POTS is (in real-life words)

I have POTS (Postural Orthostatic Tachycardia Syndrome), and the fastest way I can explain it is: my body doesn’t handle being upright the way it’s supposed to. When I go from lying down or sitting to standing, my heart rate jumps up like I’m sprinting… even if I’m literally just standing in my kitchen.

POTS is a type of orthostatic intolerance, meaning symptoms show up when I’m upright and often calm down when I sit or lie back down. For me, it can feel like my body is yelling “danger!!” when nothing dangerous is happening.

It’s also part of a bigger category called dysautonomia (autonomic nervous system dysfunction). The autonomic nervous system is supposed to run the “background tasks” of the body—heart rate, blood pressure, temperature regulation, digestion, sweating, all of it. With POTS, those background tasks can get messy.

What’s supposed to happen when someone stands up

When most people stand, the body tightens blood vessels and adjusts circulation so blood doesn’t just drop toward the legs because of gravity. The heart rate might rise a little, but it stays reasonable.

With POTS, that adjustment can be disrupted. So instead of a smooth transition, it’s like: blood pools downward, the brain gets less steady blood flow, and the body tries to “fix it” by sending the heart rate way up. That’s why it can feel like a cardio workout… just from existing upright.

The diagnostic criteria I keep seeing (and what it means day-to-day)

One of the most common diagnostic markers people talk about is: heart rate increases by at least 30 beats per minute within 10 minutes of standing (and symptoms have been going on for months). For younger teens, the number can be higher.

That sounds so clinical, but the day-to-day version is: I can stand up, and within minutes I’m dizzy, shaky, nauseous, or my vision goes weird. Sometimes it’s “only” a racing heart. Sometimes it’s the whole package.

“It’s just a high heart rate” (no… it’s not)

This is the part I wish more people understood: POTS isn’t just tachycardia. The heart rate is the obvious sign, but the experience can be way bigger and way more disruptive.

Here are symptoms that can show up for me (and for a lot of POTSies I’ve talked to):

• dizziness / lightheadedness
• presyncope (that “I’m about to pass out” feeling)
• syncope (actually fainting, especially if I push through warnings)
• brain fog (forgetting words mid-sentence, losing my train of thought)
• headaches or sudden migraines
• nausea (sometimes out of nowhere)
• shakiness / tremors
• palpitations (feeling my heart pounding or fluttering)
• temperature dysregulation (too hot, too cold, sweating too much, or not sweating right)
• blood pooling in hands/feet (color changes, swelling, heaviness)
• shortness of breath even when I’m not “doing” anything
• fatigue that feels different than sleepy (more like my battery is drained)

And the wild part is: symptoms can rotate. One day it’s mostly dizziness. Another day it’s mostly GI issues and brain fog. Another day it’s “why does standing feel like climbing a mountain.”

The “three times more energy” thing is not a metaphor

One of the most validating things I learned is that people with POTS may use significantly more energy just to stand compared to someone without POTS. That explains why I can do something “small” (shower, make food, walk to the car) and feel like I ran a marathon.

It’s not laziness. It’s not being dramatic. It’s a nervous system problem that makes basic tasks cost more.

Signs I noticed before I had a name for it

Before testing, before appointments, before I knew what POTS even was, I had patterns that didn’t make sense:

• I wasn’t “just tired.” It was a heavy, body-wide exhaustion that didn’t match what I did that day.
• I felt weaker when standing. Like my legs were trying to quit on me.
• I craved salt constantly. Not in a cute “I love snacks” way—more like my body was begging for it.
• I had blood pooling in my hands and feet. Sometimes they’d look discolored or feel swollen and weird.
• I had facial numbness or lip shaking. That one scared me the first time it happened.
• Sudden migraines. Especially when I was run down or overheated.

If any of this sounds familiar, I’m not diagnosing anyone. I’m just saying: it’s worth tracking patterns and bringing them to a doctor who understands orthostatic conditions.

Heat is my personal villain

POTS and heat do not mix. At all. Hot days can turn me into a faint-risk version of myself so fast it’s honestly rude.

Heat can dilate blood vessels and make blood pooling worse, which can make symptoms spike. For me, summer can feel like a season-long strategy game: planning errands around cooler hours, dressing in layers I can remove, and always having a backup plan if I start getting that “uh oh” feeling.

There have been times I’ve had to sit in the car after an appointment and just… recover. Not because the appointment was emotionally hard, but because being upright + walking + heat = symptoms stacking on symptoms.

My “invisible illness” reality

POTS can be invisible from the outside. I can look fine while my heart is racing and my vision is tunneling. That invisibility is one of the hardest parts, because it can invite comments like:

“You’re too young to have that.”
Okay… I’ll let my nervous system know. 🙃

It’s also why I’m big on educating. Not because I want pity, but because I want fewer people to feel alone and confused the way I did.

How I got taken seriously (and what helped me advocate)

One thing I learned the hard way: it can take multiple appointments to find someone who truly understands POTS. Some people get bounced from doctor to doctor, told it’s anxiety, told to “drink water,” told it’s nothing… while symptoms keep getting worse.

What helped me advocate more clearly was tracking:

• heart rate changes from lying to standing
• blood pressure trends if I could safely measure
• symptom triggers (heat, dehydration, long standing, big meals, lack of sleep)
• fainting or near-fainting episodes (what happened right before, how long recovery took)

Some people end up wearing a heart monitor for a few weeks to rule out other issues and to capture patterns. Even when the heart itself is structurally “normal,” the data can still show how intense the heart rate swings are with posture changes.

My day-to-day management (what actually makes life easier)

There’s no one routine that fixes everything, but these are the things I come back to when I’m trying to make POTS more livable.

1) I pace like it’s my job

My biggest tip is taking it easy and listening to my body. I used to push through warning signs because I didn’t want to be “dramatic.” Now I treat early symptoms like a notification, not a challenge.

If I feel presyncope building, I sit or lie down. I don’t negotiate with it. I’ve learned that pushing through can turn a manageable flare into a full crash.

2) Hydration is non-negotiable

I drink often, not just when I’m thirsty. If I wait until thirst hits, I’m already behind. Hydration can help support blood volume, which can reduce symptoms for some people.

I also pay attention to timing: mornings can be rough, and hydration early can make the day less brutal.

3) Salt (when it’s appropriate for me)

Many POTS patients are told to increase salt and fluids to support blood volume, but this is something I treat as individualized and doctor-guided. For me, salty foods can help on symptom-heavy days, especially when I’m also hydrating.

I don’t frame it as “eat salt and you’re cured.” It’s more like: salt can be one tool in the toolbox.

4) Compression helps more than I expected

Compression garments can help reduce blood pooling in the legs. On days when standing feels impossible, compression can make the difference between “I can’t” and “I can, but carefully.”

5) Gentle movement, not punishment workouts

Exercise intolerance is real with POTS, and for a long time I thought that meant I should avoid movement completely. What I’ve learned is that the type and pacing of movement matters.

Very gentle, consistent movement—especially things that don’t start fully upright—can be more realistic. Some days it’s stretching. Some days it’s a short walk. Some days it’s nothing but rest, and that still counts as listening to my body.

6) I respect sleep like it’s treatment

When my sleep is off, my symptoms are louder. When I’m run down, my heart rate spikes easier, my brain fog gets thicker, and my heat tolerance drops.

I don’t always get perfect sleep, but I treat rest as part of my management plan, not a reward I have to earn.

7) I track my heart rate (without spiraling)

Wearing a watch to track heart rate can be helpful for noticing trends and catching spikes early. The key (for me) is using it as information, not as something to obsess over.

It helps me answer questions like: “Am I actually okay to keep standing?” and “Is this flare building?”

8) I plan for temperature like it’s a whole strategy

Temperature regulation issues are so common with POTS. I do better when I plan ahead:

• avoiding peak heat hours when possible
• taking breaks in cool spaces
• keeping cold items nearby
• wearing layers so I can adjust fast

It’s not “extra.” It’s prevention.

What I do during a flare (my personal emergency-ish routine)

When symptoms spike, I go back to basics:

• sit or lie down immediately (especially if I feel faint)
• hydrate slowly and consistently
• cool down (shade, AC, cool cloth—whatever is available)
• elevate legs if that helps
• reduce stimulation (quiet, dimmer light, less movement)
• ask for help if I’m alone and feel unsafe

If fainting is frequent, symptoms are escalating, or something feels different than usual, I treat that as a medical situation, not something to “tough out.”

The emotional side no one warns you about

Living with POTS can be isolating. It can mess with work, school, relationships, and confidence. It can be frustrating to cancel plans because standing in a line is enough to trigger symptoms. It can be exhausting to explain an invisible illness over and over.

But there’s also something powerful about finding language for what’s happening. The moment I learned “POTS,” I stopped feeling like I was failing at being a person. I started seeing it as: my body is dealing with a real autonomic issue, and I’m learning how to live with it.

If you’re dealing with this too

If any part of this feels familiar, I’m genuinely sorry you’re in that club. You deserve to be taken seriously. You deserve care that doesn’t dismiss you. And you deserve strategies that help you function, not just survive.

I’m always learning, and I know a lot of other people are too—so if you have POTS management tips that actually help (especially for heat, brain fog, or working while symptomatic), I’m listening. 🧂
