Funny turns or fainting
Ngā āhuatanga hanga rerekē, te hemo rānei
Fainting is when you briefly lose consciousness. This is also known as a blackout. A funny turn is a short period of feeling light-headed or dizzy.
Fainting and funny turns are caused by reduced blood flow to the brain. Feeling faint comes on suddenly and lasts a short time, then you recover quickly.
Several things can trigger fainting, including:
- overheating
- standing still for a long time
- hunger
- exhaustion
- low blood pressure.
If you faint or have a funny turn, it is important to get yourself checked by a health provider. Fainting or funny turns are not usually caused by something serious. But they can be caused by an underlying health condition such as a heart problem or seizure.
What to do if you are feeling faint
The best thing to do is to lie down.
If you cannot lie down, try squatting, crossing your legs and squeezing them together or gripping your hands together and pulling.
What to do if someone is feeling faint or faints
If someone is feeling faint or has fainted:
- get them to lie down or sit down with their head between their knees
- if they are lying down, raise their legs above the level of their heart
- loosen any collars, belts or tight clothing
- make sure they have plenty of fresh air. Open a window or ask bystanders to move away.
Once the person has woken up:
- reassure them
- make sure they do not stand up too early or too quickly
- advise them to see a health provider if they faint regularly.
Important
If the person does not wake up after one minute, phone 111 and ask for an ambulance. Then follow the advice for helping an unconscious person.
Preventing fainting and light-headedness
If you are prone to fainting frequently, it is important to drink plenty of fluids and have regular meals.
Avoiding overheating is also useful.
Have more salt
If your fainting and light-headedness is caused by low blood pressure, you can slightly increase the amount of salt in your food. You can do this by sprinkling half a teaspoon of salt on your meal at night. Do not add more salt to your food if you are being treated or monitored for high blood pressure.
Wear tight clothing
If you faint quite often, especially when standing or just after exercising, it is a good idea to wear tight-fitting clothing below your waist. One of the best things to wear is compression sports clothing, commonly called Skins (their brand name). You have probably seen sportspeople wearing this.
Alternatively, you could buy below-the-knee compression stockings from your pharmacist. Ask for grade 2 compression stockings. You will need to get these measured.

Safety Issues
If you have fainted recently or are prone to fainting frequently, you may need to restrict your driving due to the risk to you and other road users. Check with your health provider whether it is safe for you to drive.
