Brain & Nervous System
Fainting
A brief blackout when the brain misses a moment of blood flow — usually harmless; lie down, raise the legs, and find the cause.
Also known as: Passing out, Syncope, Blacking out, palpitations (definition: sensation of rapid or irregular heartbeat)
📝 At a glance
Likely root causes: Standing too long, especially in heat or a stuffy room; Standing up too quickly, dropping blood pressure for a moment; Fright, pain, or the sight of blood.
First thing to try: If you feel a faint coming on, sit or lie down right away and raise your legs — this prevents a fall and restores blood flow to the brain.
See a doctor if: Fainting during exercise or exertion
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Standing too long, especially in heat or a stuffy room
- Standing up too quickly, dropping blood pressure for a moment
- Fright, pain, or the sight of blood
- Dehydration, skipped meals, or low blood sugar
- Sometimes a heart rhythm or nervous-system problem that needs checking
Change what you can
- If you feel a faint coming on, sit or lie down right away and raise your legs — this prevents a fall and restores blood flow to the brain.
- For someone who has fainted, lay them flat and gently raise their legs about a foot; loosen tight clothing.
- Let in fresh air, give them space, and keep them calm as they come around.
- Once they're fully awake, offer small sips of cool water and let them rest before standing.
- Help them get up slowly and stay with them until they feel steady.
- Through the day, drink enough water and eat regular meals to help prevent it happening again.

The essential first step — lie flat and raise the legs the moment a faint threatens or occurs.
How to do it ▾
Why it works: Fainting is a brief drop in blood flow to the brain. Lying flat removes the climb against gravity, and raising the legs returns pooled blood to the heart and head, which is usually all the body needs to recover.
- At the first wave of faintness, sit or lie down at once so a fall can't injure you.
- If someone has fainted, lay them flat on their back on the floor.
- Raise their feet about 12 inches (30 cm) above the level of the heart.
- Loosen any tight collar, belt, or clothing around the neck and waist.
- Keep them down until colour and alertness fully return, then let them rise slowly in stages.
Until fully recovered, usually a few minutes · Once, as needed
Caution: If the person does not come round within about a minute, treat it as an emergency. Do not sit or stand them up quickly, which can bring on another faint. If there are signs of injury from a fall, do not raise the legs — keep them still and get help.
When to get help: If the person does not regain consciousness within one minute, or has chest pain, trouble breathing, a seizure, an irregular pulse, or fainted during exertion, call emergency services at once.

Simple daily habits prevent most recurrent faints.
How to do it ▾
Why it works: Most simple faints come from blood pooling in the legs on standing. Tensing the legs, hydrating, and changing position gradually keep blood reaching the brain.
- Get up from bed or a chair in stages — sit first, pause, then stand.
- If you feel light-headed on standing, cross and tense your leg muscles, or sit back down.
- Drink fluids steadily and don't skip meals.
- Avoid standing still for long stretches, especially in heat or a stuffy room — shift your weight and flex your calves.

Caution: Frequent or unexplained fainting needs a medical check to rule out a heart or nervous-system cause.

Replacing fluids and rising slowly guards against a repeat faint.
How to do it ▾
Why it works: Dehydration and low blood sugar are common triggers; replacing fluid and giving the circulation time to adjust before standing keeps blood pressure steady.
- Wait until the person is fully alert and able to sit up safely.
- Offer small sips of cool water, not large gulps.
- If they may have skipped a meal, offer a light snack.
- Have them sit for several minutes, then stand slowly while you stay alongside.
- Through the day, encourage regular fluids and meals.
Over the recovery period · As needed
Caution: Give nothing by mouth until the person is fully conscious and upright. Repeated faints, or fainting without a clear trigger, should be checked by a doctor.

Fresh air and cooling speed recovery and ease the nausea that often follows.
How to do it ▾
Why it works: A stuffy, overheated room widens blood vessels and worsens the blood-flow dip behind a faint. Cooling and fresh air help the vessels recover their tone.
- Give the person room — ask any crowd to step back so air can reach them.
- Open a window or move them to fresh air if it is stuffy or hot.
- Lay a cool, damp cloth on the forehead and back of the neck.
- Speak calmly and reassure them as they come round.
A few minutes · As needed
Caution: Never give anything to drink near the mouth of someone not fully conscious. Do not give food or drink until the person is fully awake and sitting up.

Use this if a fainted person is slow to wake or might vomit, so the airway stays clear.
How to do it ▾
Why it works: Lying on the back lets the tongue or vomit block the airway. Turning the person onto their side, head tilted slightly back, keeps the airway clear and lets fluids drain from the mouth while you wait for help.
- First check that the person is breathing; if not, call emergency services and start CPR.
- Kneel beside them. Place the near arm out at a right angle, palm up.
- Bring the far arm across the chest and rest the back of that hand against their near cheek.
- Bend the far knee up, then use it to roll them gently toward you onto their side.
- Tilt the head back a little to keep the airway open, adjust the top leg for stability, and stay until help arrives.
Until the person wakes or help arrives · As needed
Caution: If you suspect a head, neck, or spine injury, do not move them unless vomiting threatens the airway; call for help and keep them still. Keep watching that they are still breathing; be ready to start CPR if breathing stops. Do not put anything in the mouth or under the head.
When to get help: Call emergency services if the person is not breathing normally, does not wake within a minute or two, had a seizure, or is injured - and begin CPR if breathing stops.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health...

🌿 Overview
Fainting is a short loss of consciousness from a brief drop in blood flow to the brain, often from standing too long, heat, fright, or dehydration. Lying flat with the legs raised restores it quickly. Because it can rarely signal something serious, fainting during exercise, with chest pain, or that repeats needs a doctor.
Fainting is a brief loss of consciousness that happens when, for a moment, the brain doesn't get enough blood flow. The person goes pale, feels lightheaded or sweaty, and then drops or slumps for a few seconds before coming around. Most of the time it's harmless — often the body's response to standing too long, a fright, the sight of blood, heat, hunger, or getting up too quickly. Warning signs often come first: dizziness, a wave of warmth, blurred or tunneling vision, ringing ears, or sweatiness. Noticing these early gives you a chance to sit or lie down before falling, which prevents injury. Lying flat and raising the legs helps blood return to the brain, and most people recover quickly. Fainting itself is usually not the real problem — it's a signal pointing to something else, from simple dehydration or low blood sugar to, less often, a heart or nervous-system issue. Because the cause matters, fainting that happens during exercise, comes with chest pain or palpitations, repeats, or follows a head injury should always be checked by a doctor.
Common signs
- A short loss of consciousness, with quick recovery
- Lightheadedness, dizziness, or a wave of warmth beforehand
- Pale, sweaty, or clammy skin
- Blurred or tunneling vision, or ringing ears
- Feeling weak or shaky afterward

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Plenty of water through the day
- Regular, balanced meals to keep blood sugar steady
- A little extra fluid and salt-containing foods in hot weather (unless your doctor limits salt)
Go easy on
- Skipping meals or going long stretches without food
- Standing up suddenly after sitting or lying
- Alcohol and very hot rooms, which lower blood pressure
Steady fluids and regular meals keep blood pressure and blood sugar from dipping — two common triggers of a faint.
⚖️ Good to know
- Fainting during exercise, or with chest pain, a pounding or irregular heartbeat, or trouble breathing, can signal a heart problem — seek care right away.
- Fainting after a head injury, or with confusion, weakness, or trouble speaking, needs emergency help.
- Never leave someone alone who has fainted until they're fully recovered; don't give fluids until they're fully awake.
- Repeated fainting always deserves a doctor's evaluation to find the cause.
