Fatigue and a lack of energy have been problems for all my life. In an effort to find out why, I've asked doctors, read books, and finally decided that some questions just won't be answered in my lifetime.

Fortunately, I've also learned that even without discovering the root causes of my tiredness, there are things I can do to alleviate it. Below are some energy boosters that have worked for me and others over the years. Try them to see which work best for you, and use more than one at a time if necessary.

1. Energetic music

Different types of music have different effects on us, but you can learn which are best for you by trial and error. Once you find the music that wakes you up, keep it ready. 

1. Sleep 

It is recommended that we get 6-8 hours of sleep per night. Try drinking something warm before bed, or relax with a simple meditation.

1. Talk about something interesting 

Have you ever seen a tired person start to talk about something they're passionate about, and suddenly "wake up." It's a powerful technique you can use for yourself. Have a few "favorite" subjects that get you going.

1. Coffee  

For some of us, caffeine makes us more tired when it's abused, but short-term, it can work wonders. 

1.  Deep breathing 

Several slow deep breaths help oxygenate the blood supply better, and especially seems to wake up the brain.

1. Have an energy drink

The verdict isn't in on most of them, but it's a cheap option to try. I seem to get something from the ones with Ginkgo Biloba in them.

1. Move your body

Sometimes just getting up and washing the dishes, or walking around the house helps boost energy levels.

1. ExerciseI

t's not a quick solution, but many people notice an increase in their energy level when they get regular aerobic exercise.

1. Hot and cold shower

Try a minute of hot water, then a minute of cold, alternating for six minutes. This isn't for those with weak hearts, but it will wake you up. Incidentally, research shows that this also revs up the immune system.

1. Get outside 

Often, a little sunshine and fresh air can be very energizing.
