How to Stop Feeling Tired All the Time

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

Be careful with caffeine. 1 or 2 caffeinated drinks per day like coffee, tea or cola can boost your energy and mental alertness, but more than 6 caffeinated drinks per day may make you anxious, irritable, and negatively affect your performance.

Eat breakfast. Food boosts your metabolism and gives your body energy to burn. The brain relies on glucose for fuel, so choose carbohydrate-rich breakfast foods such as cereals or whole grain bread.

Don't skip meals. Going without food for too long allows blood sugar levels to dip. Try to eat regularly to maintain your energy levels throughout the day.

Don't crash diet. Low calorie diets or diets that severely restrict carbohydrates don't contain enough energy for your body's needs. The typical crash diet also deprives the body of nutrients such as vitamins, minerals and trace elements.

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

Get enough sleep. Adults need about 8 hours per night.

Limit caffeine. Too much caffeine, especially in the evening, can cause insomnia. Limit caffeinated drinks to 5 or fewer per day, and avoid these types of drinks after dinner.

Learn how to relax. A common cause of insomnia is fretting while lying in bed. Experiment with different relaxation techniques until you find one or two that work for you; for example, you could think of a restful scene, focus on your breathing, or silently repeat a mantra or phrase.

Avoid reading or watching TV in bed

Introducing fatigue fighting strategies (above) into your lifestyle. A fit, healthy and well-rested body is less prone to severe drowsiness in the afternoon.

Eating a combination of protein and carbohydrates - like a tuna sandwich - for lunch. Carbohydrates provide glucose for energy, and protein provides the amino acid tyrosine, which allows the brain to synthesize the neurotransmitters dopamine and norepinephrine to keep your mind attentive and alert.

Get moving! A brisk walk or even 10 minutes of stretching at your desk can improve your blood flow and boost your energy.
