Not sure what’s causing your fatigue? Here are some common energy zappers that may be to blame – and tips on how to overcome them.
Being a couch potato
Sitting in one position for long periods of time can sap your energy, even if you’re watching the TV or using the computer. Your body equates the stillness with going to sleep.
Solution: stretch often, get up and walk around away from your desk or sofa. Frequent breaks will keep your body alert.

Poor posture wastes energy
A lot of your energy goes on keeping you upright. Bad posture – such as hunching forwards and slumping in your seat – puts your spine out of alignment. The more out of balance your spine is, the more your muscles have to work to compensate.
Solution: whether you're moving, sitting or standing still, try to make sure that your head is lined up over your body – not sticking out in front of it. Aim for your ears to be directly over your shoulders.

Crash dieting makes you tired
While it will boost your energy to lose excess weight, going on a crash diet isn’t helpful. Very low-calorie diets, especially ones that give you less than 850 calories a day, will make you feel even more tired and can damage your health in other ways.
Solution: lose weight by eating healthily, cutting out junk and sugary foods, and reducing your portion size. Aim to lose no more than 2lbs a week.

It’s all to easy to become homebound, especially if you have a young child, you work from home or you’ve been driven indoors by the cold days and long, dark nights of winter. However, lack of light and fresh air is a key cause of tiredness.
Solution: get out for a 10-minute walk at least once during the day, or when you're most tired. Even if it’s cloudy, you’ll be exposed to more natural light than inside and you’ll feel more alert. If you simply can't get out the door, a few minutes in a room filled with natural light may also help.

Sugary breakfast cereals
Sugary breakfasts, such as processed cereals, pastries, muffins and toast with sugary spreads, will give you a quick surge of energy as your blood sugar peaks. But your sugar levels will slump just as quickly a couple of hours later. The result? You crash as you run out of energy.
Solution: to get a steady release of energy all morning long, eat a breakfast that’s based on unrefined starch. For example, home-made porridge with semi-skimmed milk and a little honey, wholemeal cereal with fruit sliced over it, or an egg with wholewheat or granary toast. Try to choose breakfast cereals that are wholegrain and low in salt and sugar.

Constant worrying drains energy
If you’re fretting about something all day long, your heart rate and blood pressure rise, and your muscles tighten, leading to fatigue and aches.
Solution: set some time aside to concentrate on your worries. Try to think of positive solutions, then put the worries out of your mind. Schedule that dental appointment for first thing in the morning, so you don't spend all day fretting about it.

Exercising too much
Regular exercise is good for you, but working out intensively every day may not be good for your energy levels, especially if you’re a beginner or trying to get back in shape.
Solution: take a day off between strenuous bouts of exercise. Beware of leaving more than two or three days between sessions, or you might fall out of the habit.

Winter days increase fatigue
The shorter days of winter disrupt your sleep/waking cycle, leading to fatigue. Less sunlight in winter also means your brain produces more of a hormone called melatonin, which makes you sleepy.
Solution: Get outdoors into natural daylight as much as possible, do some exercise every day and eat the right foods for energy, such as fruit and veg.
