Vacation is something that always makes us feel good then be it just relaxing at home or reading a book or hanging out with friends. It's something that heals your soul. But now we have got one more reason to have a vacation. Even the latest study tells us how much holiday is essential for us. So the latest study says that our lifestyle and surroundings have a huge impact on our immune system. It simply makes our immune system more powerful.

This was studied by researchers gave mice two-week stay in a large cage packed with toys and this exciting environment appeared to boost their white blood cells, which fight off infections.

White blood cells protect us from various infections and diseases. They are key to auto-immune diseases such as rheumatoid arthritis and multiple sclerosis.

"This effect is remarkable because we haven't given them any drugs, all we've done is change their housing conditions. You could say that we've just put them in their equivalent of a holiday resort for two weeks and let them enjoy their new surroundings," said Fulvio D'Acquisto, Professor at Queen Mary University, London.

"We could boost the effects of standard drug treatments that deal with the mechanics of infection, by also offering something environmental that improves a patient's more general well-being. That might be a promising approach for treating chronic diseases," D'Acquisto added.

As we grow old, our immune system grows old and tired

But what about those who cannot change their environment? Mainly the old-age population. They have limited mobility. So it was observed when they were given a plant to take care of, there was a significant increase in the length of their life.

This research study clearly proves that cure is not always in the pill.
