Fatigue is the enemy of productivity and just about anything that requires movement. It has long been thought that fatigue is something that comes about with age, but experts are starting to rethink the idea that fatigue is, in fact, not an expected part of aging at all. A closer look into our own lives shows us fatigue can come from anywhere: from depression, stress, and boredom to medications like antihistamines or beta blockers. And then there is deconditioning, which basically means you’re out of shape, leading you to feel more fatigued.

If your fatigue is caused be a serious health condition, then that obviously that needs to be addressed. But if it’s not, then there are some changes you can make in your lifestyle to ward off fatigue.

The first thing you can do is increase activity. For fatigue caused by inactivity and/or deconditioning, bumping up the movement can help a lot. You don’t have to go out and try to run a marathon; take it easy, just focus on getting up more, walking, gardening, taking the stairs, et cetera.

If you’re trying to limit fatigue, you should also keep track of what you eat and drink. You should especially watch out for high-sugar and fried food, as well as alcohol and caffeine. And while you’re at it, try some fatigue-fighting snacks like edamame, melons, and nuts. These are all packed with vitamins, nutrients, and minerals that are known to boost and maintain one’s energy.

Boredom can be another source of fatigue—one that works like a vicious circle. If you’re bored, it can add to fatigue, which makes it harder to fight the boredom, which makes one feel more fatigued – you see where this is going. To fight boredom, tap into your interests and explore the options: Find a new hobby or resume an old one, join or start a group or club, or just get more involved in the community.

Lastly, improve your sleep to fight fatigue. While fatigue isn’t always caused by too little sleep, improved sleep duration and quality for those who struggle is a good place to start.
