Feel faint in a hot shower

You are under the hot water when your head starts to swim. The room may look grey, and sound can go dull or far away. Some people have to sit down on the shower floor fast.

Heat makes the small blood vessels in your skin open wide. Blood pools near the surface and in your legs. For a moment, less of it gets up to your brain.

Low blood pressure makes this more likely. Standing still in a long, steamy shower adds to it. So can an empty stomach, too little water, alcohol, or some pills for blood pressure.

When to see someone

See a doctor if you have passed out in the shower, even once. Get help right away if it comes with chest pain, a pounding heart, slurred speech, or a bad headache. Book a visit if it happens most days, if you are pregnant, or if you take heart or blood pressure pills.

How to read the grades below

Below is a list of remedies people have used for low blood pressure. Each one has a grade for how strong the evidence behind it is. A low grade means the proof is thin, so talk to your doctor before you try something new.

Low Blood Pressure (Hypotension): natural remedies and the evidence behind them

When does your low blood pressure bother you most?

I get dizzy or lightheaded when I stand up or after meals

  1. Compression Therapy

    Supported by smaller clinical studies· Recognised traditional use (Evidence grade B · Traditional use recognised)Recognised traditional use

    Cuts leg blood pooling when you stand

    Why it may be relevant
    If standing leaves you dizzy, compression garments stop blood from pooling in your legs so more stays available to your heart and brain.
    Why try it
    Graduated compression stockings or an abdominal binder are a long-standing, low-risk way to ease standing dizziness from low blood pressure. Small randomized crossover trials in people with orthostatic hypotension found abdominal compression can raise standing blood pressure, which is why it earns a B here - promising, though the studies are small.
    Dose or use
    Wear waist-high graduated compression stockings (or an abdominal binder) during the day while you're upright; take them off at night.
    Time to results
    Immediate while worn.
    Key study
    Randomized Controlled Trial (2015, PMID 25448247): Effects of patient-controlled abdominal compression on standing systolic blood pressure in adults with orthostatic hypotension. This crossover trial in adults with neurogenic orthostatic hypotension found abdominal compression improved standing systolic blood pressure; trials are small, so the effect is encouraging rather than definitive.
    Caution
    Get the right fit; too tight can pinch or restrict circulation. Check with a clinician first if you have peripheral artery disease or diabetes.
  2. Caffeine

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · Traditional use recognised)Recognised traditional use

    A morning coffee can blunt standing dizziness

    Why it may be relevant
    When you feel lightheaded on standing or after a meal, caffeine's quick vessel-narrowing effect can steady your blood pressure enough to get moving.
    Why try it
    Caffeine temporarily narrows blood vessels and can nudge blood pressure up, which is why many people reach for coffee when they feel lightheaded. The clinical evidence is limited and mixed, so it earns a C - use it as a simple everyday measure, not a reliable treatment.
    Dose or use
    A cup of coffee or strong tea (about 100-200 mg caffeine), ideally in the morning or before a meal that tends to leave you woozy.
    Time to results
    Within 15-45 minutes of drinking it.
    Key study
    Systematic Review (2021, PMID 34143333): The effects of caffeine in adults with neurogenic orthostatic hypotension. The review found only a handful of small studies, several combining caffeine with ergotamine, with inconsistent results for caffeine alone and high risk of bias - hence the cautious C grade.
    Caution
    Can cause jitters, a racing heart, or poor sleep; avoid late in the day and go easy if you have an arrhythmia or anxiety.
  3. Vitamin B12 (Cobalamin) Deficiency

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    B12 shortfall can cause anemia and dizziness

    Why it may be relevant
    Being pale, tired, or lightheaded along with low blood pressure can point to low B12, which causes anemia and affects the nerves that steady your blood pressure.
    Why try it
    B12 deficiency leads to anemia and autonomic changes that can produce orthostatic low blood pressure, a commonly missed but correctable cause. This card is educational; confirm with a blood test.
    Dose or use
    Ask for a B12 (and folate) test, especially if you're older, vegetarian or vegan, or on acid-reducing or metformin medication; treat as directed.
    Time to results
    Symptoms often ease over several weeks to a few months after replacement.
    Key study
    B12 deficiency is a recognized reversible cause of orthostatic low blood pressure; this is educational guidance, not a graded treatment.
    Caution
    Persistent numbness, balance problems, or severe fatigue need a clinician; B12-related nerve damage can become permanent if ignored.
  4. DU20 (Baihui) - Governing Vessel 20

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Crown point traditionally used to lift energy

    Why it may be relevant
    For the lightheadedness and faintness of low blood pressure, DU20 on the crown of the head is the classic point used to 'lift' energy upward.
    Why try it
    In Traditional Chinese Medicine, DU20 (Baihui) is used for dizziness, mental fog and fatigue by raising yang qi. This is traditional practice, not a clinically graded treatment.
    Dose or use
    Apply gentle, steady pressure to the crown of your head for 1-2 minutes, breathing slowly; repeat when you feel woozy.
    Time to results
    Some people feel steadier within minutes; effects are subtle.
    Key study
    Traditional TCM point for dizziness and fatigue tied to low energy; not clinically graded in our records.
    Caution
    Use light pressure only. This is not a substitute for medical care if you're actually fainting or falling.

I mostly feel tired, drained, or run-down all day

  1. Iron Deficiency

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Iron-deficiency anemia can cause low BP

    Why it may be relevant
    If you're pale, breathless, or wiped out along with low blood pressure, iron-deficiency anemia is a common, correctable cause worth ruling out.
    Why try it
    Low iron means fewer oxygen-carrying red blood cells, which brings on fatigue, dizziness, and low blood pressure. A simple blood test can confirm it. This card is educational; get tested before supplementing.
    Dose or use
    Ask for a ferritin/iron panel and blood count; supplement only if levels are low and as directed.
    Time to results
    Energy and symptoms typically improve over 4-12 weeks once iron is replaced.
    Key study
    Iron-deficiency anemia is a recognized cause of low blood pressure and fatigue; this is educational guidance, not a graded treatment.
    Caution
    Don't self-dose iron; too much is toxic and constipating. Confirm a deficiency with testing first.
  2. Licorice root (Glycyrrhiza glabra)

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Classic herb that helps raise low blood pressure

    Why it may be relevant
    When low blood pressure leaves you tired and drained, licorice is the classic herb that gently raises pressure and supports the adrenal side of low energy.
    Why try it
    Whole licorice contains glycyrrhizin, which promotes sodium and water retention and is traditionally used for low blood pressure and adrenal fatigue (our library lists 'adrenal insufficiency' and 'chronic fatigue syndrome'). This is traditional use, not clinically graded here.
    Dose or use
    Use whole, glycyrrhizin-containing licorice root as a tea or standardized extract per the label; short courses only.
    Time to results
    A few days to a couple of weeks of regular use.
    Key study
    Traditionally used for low blood pressure and adrenal fatigue; this specific use has not been confirmed in controlled clinical trials in our records.
    Caution
    Because it raises blood pressure and lowers potassium, avoid it if you have high blood pressure, heart or kidney disease, or are pregnant; limit to a few weeks and don't combine with BP or diuretic medication without medical advice.
  3. Panax ginseng extract (Red Ginseng)

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Adaptogen for the fatigue that comes with low BP

    Why it may be relevant
    If your low blood pressure mostly shows up as feeling tired and run-down, ginseng is traditionally used to build energy and resilience to stress.
    Why try it
    Panax ginseng (red ginseng) is an adaptogen used for centuries for fatigue and low vitality. We're framing it as traditional energy support, not a graded blood-pressure treatment.
    Dose or use
    Standardized Panax ginseng extract per the label, usually in the morning; take breaks after several weeks of use.
    Time to results
    Often 2-4 weeks of daily use.
    Key study
    Traditional adaptogen use for fatigue and low vitality; not clinically graded for blood pressure in our records.
    Caution
    Can cause insomnia or jitteriness and may interact with blood thinners and diabetes medication; it can also affect blood pressure, so monitor if you take BP drugs.
  4. DU20 (Baihui) - Governing Vessel 20

I want to find out what's actually behind it (like a deficiency)

  1. Iron Deficiency

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Iron-deficiency anemia can cause low BP

  2. Sodium Deficiency

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Low sodium directly lowers blood pressure

    Why it may be relevant
    If your low blood pressure flares when you're dehydrated, hot, or eating little salt, low sodium may be the direct cause; it shrinks the fluid volume in your blood.
    Why try it
    Sodium holds fluid in your bloodstream, so when it drops, blood pressure drops too. Checking and correcting low sodium is a well-established, first-line step for low blood pressure. This card is educational; confirm with a clinician before loading up on salt.
    Dose or use
    Ask about a sodium (electrolyte) check if you sweat heavily, over-hydrate, or eat very low-salt, then adjust salt and fluids on medical advice.
    Time to results
    Blood pressure can respond within days of correcting a true deficit.
    Key study
    Low sodium is a recognized correctable cause of low blood pressure; this is educational guidance, not a graded treatment.
    Caution
    Don't add lots of salt on your own if you have heart, kidney, or high-blood-pressure conditions; extra sodium can be harmful.

  3. Himalayan Sea Salt

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Salt plus fluids help expand low blood volume

    Why it may be relevant
    When heat, dehydration, or a low-salt diet drops your pressure, a little extra salt and water is the simplest way to bring your blood volume back up.
    Why try it
    Himalayan salt supplies sodium and trace electrolytes that help you hold onto fluid and stay hydrated (our library cites hydration and electrolyte balance). Used here as a practical measure, not a clinically graded treatment.
    Dose or use
    Add a pinch to water or food and drink fluids, especially in heat or after exercise, staying within any salt limit your clinician sets.
    Time to results
    Often within hours of rehydrating with salt and fluids.
    Key study
    Sodium and fluid intake is a standard lifestyle measure for low blood pressure; not clinically graded here.
    Caution
    Salt is still salt; avoid extra sodium if you have high blood pressure, heart, or kidney disease.
