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.

Preventing fainting and light-headedness

If you're prone to fainting frequently, it's 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're being treated or monitored for high blood pressure.

Wear tight clothing

If you faint quite often, especially when standing or just after exercising, it's 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've probably seen sportspeople wearing these.

Alternatively, you could buy below-the-knee compression stockings from your pharmacist. Ask for grade two compression stockings. You'll need to get these measured.
