Most of the time, fatigue can be traced to one or more lifestyle habits, such as physical exertion, sleeping patterns, diet and emotional stress. In some cases, fatigue is a symptom of an underlying medical condition that may require medical treatment.

Have a look at your diet, which is important if you want more vitality in life. Here are some ideas that could help you feel invigorated:

Drink plenty of water. A dehydrated body functions less efficiently.

Limit caffeine. Limit caffeinated drinks (such as tea and coffee) to one or two a day, and avoid them after dinner as they can cause insomnia.

Eat breakfast. Food gives your body and brain fuel to burn, so choose a carbohydrate-rich breakfast such as wholegrain cereals or bread.

Don't skip meals. Going without food for too long allows blood sugar levels to drop.

Don't crash diet. Low-kilojoule and low-carbohydrate diets don't contain enough energy, vitamins or minerals for the body's needs.

Don't overeat. Large meals can drain your energy. Try eating six mini-meals to maintain energy levels and more a constant blood sugar level throughout the day.

Eat a healthy diet. Increase the amount of fruit, vegetables, wholegrain foods, and low-fat dairy products in your diet. Reduce the amount of high-fat, high-sugar and high-salt foods.

Eat iron rich foods. Women, in particular are prone to iron-deficiency (anaemia), one of the symptoms of which can be fatigue. If you are concerned regarding your iron levels, talk to your doctor who can have these tested.
