Post-travel depression, or PTD, commonly happens after you're gone from a long and pleasurable holiday and have returned back home. "Vacation depression" is real, and in some cases, it's one of the reasons why people decide to take fewer and shorter vacations, according to NBC News.

"Traveling naturally causes you to re-evaluate your own life and environment, which can bring dissatisfactions to the surface," said Alice Boyes, the author of "The Anxiety Toolkit," according to Wanderlust.

Here are a few suggestions you can take to beat PTD:

1) Start planning your next trip and turn your depression into anticipation. Maybe looking at travel sites and brochures will allow you to dream about your next dream vacation, Lonely Planet notes.

2) Start saving up. Traveling is expensive, and if your last trip nearly had you broke, then aim to set aside money for your next trip regularly. This way, you have a goal to focus on and you can forget about your PTD.

3) Have mini-adventures in your own hometown. While that next big vacation is still in its planning phase, why not feed your wanderlust by taking road trips near and around you? There might be sites you have yet to visit, or perhaps revisit with a new perspective and a renewed interest. Checking out your backyard is a good way to keep the magic of adventure and exploration alive, according to Operation Groundswell.

4) Get busy with a new hobby or keep abreast with people with similar interests. How about writing down a journal or blog to reflect on your previous travel experiences? It can be therapeutic. Be inspired by these travel Tweeters, Insight Guides notes.

5) Reconnect with constant people in your life. Get back into the grind and touch base with friends and family you've missed while you're away. Perhaps have a get together at your place to make your transition easier.
