Many cases of tiredness are due to stress, not enough sleep, poor diet and other lifestyle factors. Try these self-help tips to restore your energy levels.
If you feel you're suffering from fatigue, which is an overwhelming tiredness that isn't relieved by rest and sleep, you may have an underlying medical condition. Consult a GP for advice.
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 3 to 4 hours, rather than a large meal less often.
Get moving
You might feel that exercise is the last thing on your mind. But, in fact, regular exercise will make you feel less tired in the long run, so 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 it up gradually over weeks and months until you reach the recommended goal of 2 hours 30 minutes 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 and keep it off is to be more active and do more exercise.
Sleep well
Many people don't get the sleep they need to stay alert through the day.
The website of the Royal College of Psychiatrists has information on sleeping well.
Tips for sleeping well include:
- going to bed and getting up in the morning at the same time every day
- avoiding naps in the day
- taking time to relax before you go to bed
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
- yoga or tai chi
- listening to music or reading
- 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, or tiredness caused by stress, anxiety or low mood.
See a GP for a referral for talking treatment on the NHS, or for advice on seeing a private therapist.
Cut out caffeine
Caffeine is a stimulant which means it makes you feel more awake. But it can also disrupt your usual sleep rhythms, leading to problems sleeping and then daytime tiredness.
Products that caffeine is found include:
- coffee
- tea
- fizzy drinks
- energy drinks
- some painkillers and herbal remedies
The effects of caffeine on the body can last up to 7 hours, so you may want to avoid it in the evening if you are having trouble sleeping.
If you do want to cut caffeine out of your diet completely then the charity The Sleep Charity recommends you reduce your intake gradually. Trying to suddenly stop can lead to insomnia and headaches.
Drink less alcohol
Although a couple of glasses of wine in the evening can help you fall asleep, you sleep less deeply after drinking alcohol. The next day you'll be tired, even if you sleep a full 8 hours.
Cut down on alcohol before bedtime. You'll get a better night's rest and have more energy.
The NHS recommends that men and women should not regularly drink more than 14 units a week and should try to have several alcohol-free days each week.
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.
