Getting tired can mainly be attributed to lack of proper sleep, incomplete diet, excessive drinking or smoking. For a normal Adult (18+) a minimum of 8 hours of sleep is required. Incomplete sleep will lead to yawning, tiredness, dullness and leave you out of energy. As a result at the end of the day you cannot expect to be still active.

One of the other major factor is stress. Negative thinking will zap all our energy out leaving us feeling low and inactive. But if staying active is your daily struggle then lack of physical activity could be the reason. Exercises are important to increase stamina and endurance for long hours of work.

The best ways to stay active and full of energy is to focus on your diet. Eat high energy foods such as fish, bananas, fresh vegetables, juices and so on. The food which must be avoided should be milk products, junk food (chips and cola) and meat (pork/beef). Chocolates and ice creams are high on fat but high energy food too. They are feel good food which changes your mood.

Sometimes you are following a right diet and exercising everyday but still that exhausting feeling still lingers, then the last resort would be to try sleeping for 1-2 hours extra then normal and see if there are any improvements.
