Travel greatly increases the risk of falling ill

Though the travelling and having holidays at exotic locations has become a status symbol in indian society, one of the lesser known risks of travelling is that it greatly increases the risk of falling ill, due to stress, and exposure to infectious diseases.
At home , a person is able to control his or her environment to a very great extent, at an office or a shop, there is greater possibility that a person will be infected due to office colleagues, customers and others, while travelling there is very less control over whom the person will come in contact with.
While travelling, many people are more stressed as they are in an unfamiliar environment, reducing their immunity levels and making them ill.
Also staying in a hotel also increases the risk of diseases as the hotel guests are from all over India, and the airconditioning may cause illness.
