How to Manage POTS Symptoms: 7 Lifestyle Tips That Can Help

Published by Tavo | Klarity | ~8 min read

Living with postural orthostatic tachycardia syndrome is genuinely difficult. The symptoms — racing heart, dizziness, brain fog, fatigue — are disruptive on their own. The fact that they're often invisible to others, and that POTS frequently goes undiagnosed for years, makes the experience harder still.

This article isn't a treatment plan. POTS is a complex condition requiring proper medical management, and any changes to your routine should be discussed with your healthcare team first. What it is is a clear, evidence-informed overview of the lifestyle factors that consistently come up in POTS management — the practical adjustments that many people with POTS find meaningful alongside their medical care.

What Is POTS?

POTS — postural orthostatic tachycardia syndrome — is a form of dysautonomia, a condition affecting the autonomic nervous system's ability to regulate involuntary functions including heart rate, blood pressure, digestion, and body temperature.

In people with POTS, blood vessels don't respond and constrict the way they should when standing. Blood pools in the lower body, and the heart has to beat significantly faster to compensate — by definition, a heart rate increase of 30 beats per minute or more (or a rate above 120bpm) within ten minutes of standing, without a significant drop in blood pressure.

Common symptoms include:

• Lightheadedness and fainting, particularly when standing
• Heart palpitations and elevated heart rate
• Cognitive difficulties — brain fog, memory problems, difficulty concentrating
• Nausea
• Severe, persistent fatigue
• Excessive sweating
• Headaches

Symptoms typically worsen with prolonged standing, heat exposure, and large meals. POTS can occur as a primary condition or develop secondary to another condition such as lupus, diabetes, or following a viral illness — a pattern that became significantly more recognised following COVID-19.

How to Manage POTS Symptoms: 7 Lifestyle Adjustments

1. Prioritise Fluid and Electrolyte Intake

Adequate fluid and sodium intake is one of the most widely recommended lifestyle interventions in POTS management — not as a wellness choice, but as a physiologically grounded strategy for addressing one of the condition's core mechanisms.

When blood volume is low, less blood is available to be pumped to the upper body when standing. Increasing fluid intake raises blood volume, reducing the compensatory heart rate elevation that defines POTS. Sodium is critical to this process because it helps your body retain the fluid you consume rather than excreting it. Without adequate sodium, drinking more water produces limited benefit — the fluid passes through without meaningfully expanding blood volume.

Many POTS specialists recommend fluid intake of 2–3 litres per day alongside increased sodium, though individual targets should be established with your healthcare team based on your specific presentation and any other conditions.

Electrolytes beyond sodium also matter. Potassium works with sodium to regulate fluid balance and support heart muscle function. Magnesium supports cardiovascular function and is involved in nerve signalling throughout the autonomic nervous system. Chloride plays a role in fluid regulation and helps the body absorb other minerals effectively.

When choosing an electrolyte supplement for POTS, ingredients matter significantly. Sugar can worsen POTS symptoms through blood glucose spikes and crashes, which place additional stress on an already dysregulated autonomic nervous system. Artificial sweeteners have been associated with digestive distress — a concern given that POTS frequently involves gastrointestinal symptoms. A sugar-free electrolyte formula with no artificial additives and a complete mineral profile is the most appropriate option for most people with POTS.

Klarity contains six electrolytes — sodium, potassium, magnesium glycinate, chloride, calcium, and phosphorus — with no added sugar and no artificial sweeteners. It is one option worth discussing with your healthcare provider as part of your hydration strategy.

2. Eat Smaller, Lower-Carbohydrate Meals

After eating, your body redirects blood flow toward the digestive system to support digestion. For people with POTS — where blood pooling and circulation are already compromised — a large meal can significantly worsen symptoms, particularly lightheadedness, fatigue, and heart palpitations. This response is sometimes called postprandial hypotension and is a recognised component of POTS symptomatology.

Eating smaller portions more frequently throughout the day reduces the volume of blood redirected at any one time, which many people with POTS find meaningfully reduces post-meal symptom flares.

The composition of meals also matters. Refined carbohydrates and high-sugar foods produce rapid blood glucose spikes followed by crashes. These fluctuations are stressful to the autonomic nervous system and can worsen POTS symptoms. A diet lower in refined carbohydrates, with adequate protein at each meal and a balance of vegetables and lower-glycaemic fruits, tends to produce more stable blood glucose and a more predictable symptom profile.

Some people with POTS also find that dairy or gluten sensitivity compounds their symptoms. This varies significantly between individuals and is worth exploring with guidance from a dietitian or your healthcare team.

3. Understand the Role of Alcohol and Caffeine

Alcohol should generally be avoided or minimised with POTS. It is a vasodilator — it widens blood vessels — which compounds the blood pooling problem that POTS already creates. It is also a diuretic that accelerates fluid and electrolyte loss, working directly against the fluid volume strategies central to POTS management.

Caffeine is more nuanced. For some people with POTS, caffeine worsens symptoms — it can elevate heart rate and increase the anxiety and palpitations that POTS already produces. For others, caffeine's vasoconstrictive properties may actually provide mild benefit. This is genuinely individual and worth a direct conversation with your specialist rather than a general recommendation either way.

4. Adjust Your Sleep Position

Elevating the head of your bed by approximately 30 degrees — so your body is on a gentle incline with your feet lower than your hips — can help reduce the fluid shifts that worsen morning POTS symptoms.

The mechanism: sleeping flat allows fluid to redistribute more evenly through the body overnight. When you stand in the morning, the adjustment your cardiovascular system needs to make is larger, and symptoms are often at their worst. A gentle incline during sleep reduces this redistribution, making the transition to standing less abrupt.

This requires elevating the bed frame or using purpose-made risers, not simply adding extra pillows. Propping your head and shoulders with pillows without inclining the rest of your body does not produce the intended effect and may cause neck or back discomfort.

5. Minimise Prolonged Standing

Standing for extended periods is one of the most reliable POTS triggers. Blood pools progressively in the lower extremities without adequate return to the heart, which forces increasingly rapid compensatory heart rate increases over time.

When standing is unavoidable — whether at work, travelling, or in social settings — there are strategies that help:

Muscle activation. Regularly flexing and contracting the muscles in your calves, thighs, and feet while standing acts as a pump, pushing pooled blood back toward the heart. Shifting weight from foot to foot, toe raises, and small marching movements all serve this function.

Crossing legs. When seated, crossing one leg over the other increases venous return. Some people find this position helpful as a brief intervention when symptoms begin to rise.

Pre-standing hydration. Research has shown that drinking approximately 500ml of water before standing can meaningfully improve orthostatic tolerance. One study found that POTS patients who drank this volume before standing were able to tolerate an upright position 36% longer than those who didn't. The effect is temporary but practical for situations where extended standing is anticipated.

Positioning when possible. Leaning against a wall, keeping one foot elevated on a step, or finding any position that reduces the vertical column of blood in the lower extremities can reduce symptom intensity during unavoidable standing.

6. Build a Sustainable Exercise Routine

Regular, appropriately designed exercise is one of the most evidence-supported long-term interventions for POTS, despite the fact that exertion often worsens symptoms in the short term. The goal is carefully graduated cardiovascular conditioning that improves autonomic nervous system regulation and blood volume over time.

The key distinction for most people with POTS — particularly in earlier or more severe presentations — is between upright and recumbent exercise. Upright exercise (running, cycling on a standard bike, most gym machines) requires the cardiovascular system to maintain blood pressure and heart rate simultaneously against gravity, which can be poorly tolerated. Recumbent options eliminate or significantly reduce this challenge:

• Recumbent cycling — most specialist-recommended starting point
• Swimming and pool-based exercise — the pressure of water on the lower body provides natural compression and assists venous return
• Rowing machines — primarily seated, significant cardiovascular benefit
• Pilates and resistance training — particularly exercises that strengthen the lower body musculature, which serves as a secondary pump for venous blood return

Any exercise programme for POTS should be developed with your healthcare team or a physiotherapist with autonomic condition experience. Pushing through significant symptom worsening is not productive — graduated progression based on tolerance is the evidence-supported approach.

7. Consider Compression Garments

Compression socks and garments apply external pressure to the lower extremities, counteracting the blood pooling that occurs in POTS when standing or changing position. This is a mechanically direct intervention — the compression physically assists the veins in returning blood to the heart.

Compression socks rated at 20–30 mmHg are commonly recommended for POTS. If you haven't worn compression socks before, starting with a lower compression level (15–20 mmHg) allows you to adjust to the sensation before moving to higher pressures.

Full-length compression tights or abdominal binders, which extend compression higher up the body, may provide additional benefit over knee-length socks alone — particularly for people with significant blood pooling. This is worth discussing with your doctor in the context of your specific symptom profile.

Frequently Asked Questions

What is POTS and what causes it?

POTS (postural orthostatic tachycardia syndrome) is a form of dysautonomia — a condition affecting the autonomic nervous system's regulation of heart rate, blood pressure, and other involuntary functions. It is characterised by a heart rate increase of 30+ beats per minute within ten minutes of standing. Causes vary and include nerve damage from conditions like diabetes or lupus, genetic factors, deconditioning, and post-viral syndromes — including post-COVID POTS, which has become significantly more recognised since 2020.

Do electrolytes help with POTS?

Electrolytes — particularly sodium, potassium, and magnesium — are a key component of POTS lifestyle management for many patients. Sodium helps the body retain fluid and expand blood volume, which reduces the cardiovascular compensation required when standing. The appropriate electrolyte intake for POTS should be established with your healthcare team, as targets vary significantly by individual.

Why does sugar make POTS symptoms worse?

Blood glucose spikes from high-sugar foods and drinks place additional stress on the autonomic nervous system through rapid glucose and insulin fluctuations. For people with POTS — whose autonomic regulation is already compromised — these fluctuations can worsen symptoms including heart palpitations, fatigue, and lightheadedness. Blood glucose crashes following a spike can compound this effect further.

Is exercise safe for people with POTS?

Carefully designed exercise is not only safe but evidence-supported as a long-term management strategy for many people with POTS. The approach matters significantly — recumbent exercise (recumbent cycling, swimming, rowing) is usually better tolerated than upright exercise, particularly initially. Any exercise programme should be developed with medical guidance and progressed gradually based on individual tolerance.

Why does eating a large meal worsen POTS symptoms?

After eating, the body redirects blood flow to the digestive system to support digestion — a process called postprandial blood pooling. For people with POTS, this redistribution adds to the cardiovascular strain of maintaining circulation to the upper body, often worsening lightheadedness, fatigue, and heart palpitations. Eating smaller meals more frequently reduces the volume of blood redirected at any one time.

Can POTS be managed without medication?

Lifestyle modifications — including fluid and sodium intake, dietary adjustments, appropriate exercise, compression garments, and positional strategies — are a cornerstone of POTS management and can be meaningful for many people either alone or alongside medication. However, POTS varies significantly in severity and underlying cause. Whether medication is appropriate or necessary is a clinical decision that should be made with a specialist — typically a cardiologist, neurologist, or autonomic specialist.

What should I look for in an electrolyte drink for POTS?

For POTS specifically, the most important criteria are: meaningful sodium content (check the label — some electrolyte products contain very little), no added sugar (which can worsen autonomic instability through glucose fluctuations), no artificial sweeteners (which can cause gastrointestinal distress), and a reasonably complete electrolyte profile including potassium and magnesium. Always discuss specific sodium targets with your healthcare provider before significantly increasing your intake.
