Many cases of unexplained tiredness are due to stress, not enough sleep, poor diet and other lifestyle factors.
Eat often to beat tiredness
A good way to keep up your energy through the day is to eat regular meals and healthy snacks every three to four hours, rather than a large meal less often.
Perk up with exercise
You might feel too tired to exercise, but regular exercise will make you feel less tired in the long run, and you’ll have more energy. Even a single 15-minute walk can give you an energy boost, and the benefits increase with more frequent physical activity. Start with a small amount of exercise. Build up your physical activity gradually over weeks and months until you reach the recommended goal of two-and-a-half hours of moderate-intensity aerobic exercise, such as cycling or fast walking, every week.
Lose weight to gain energy
If your body is carrying excess weight, it can be exhausting. It also puts extra strain on your heart, which can make you tired. Lose weight and you’ll feel much more energetic. Apart from eating healthily, the best way to lose weight is to be more active and do more exercise.
It sounds obvious, but two-thirds of us suffer from sleep problems, and many people don’t get the sleep they need to stay alert through the day. The UK Royal College of Psychiatrists advises going to bed and getting up in the morning at the same time every day; avoid naps through the day, and have a hot bath before bed (as hot as you can bear without scalding you) for at least 20 minutes.
Reduce stress to boost energy
Stress uses up a lot of energy. Try to introduce relaxing activities into your day. This could be working out at the gym, or a gentler option, such as listening to music, reading or spending time with friends. Whatever relaxes you will improve your energy.
Talking therapy beats fatigue
There’s some evidence that talking therapies such as counselling or cognitive behavioural therapy (CBT) might help to fight fatigue.
Cut out caffeine
The Royal College of Psychiatrists recommends that anyone feeling tired should cut out caffeine. It says the best way to do this is to gradually stop having all caffeine drinks (this includes coffee, tea and cola drinks) over a three-week period. Try to stay off caffeine completely for a month to see if you feel less tired without it. You may find that not consuming caffeine gives you headaches. If this happens, cut down more slowly on the amount of caffeine that you drink.
Drink more water for better energy
Sometimes you feel tired simply because you’re mildly dehydrated. A glass of water will do the trick, especially after exercise.
