What do you need to do to make your trip comfortable?
India differs significantly from European countries in terms of compliance with sanitary standards. Therefore, if you are afraid of catching any infection, it is better to get vaccinated before traveling. It is necessary to be vaccinated primarily against dysentery, hepatitis A and B, malaria, typhoid fever and cholera.
Travel insurance is mandatory, especially if you plan to have extreme entertainment and rent a bike. To be honest, for three years, insurance has never been useful to me thanks to a well-assembled first aid kit.
The first aid kit must contain antipyretic, painkillers, medicines for intestinal disorders, adsorbents, anti-allergenic, antiseptics, broad-spectrum antibiotics and drugs that you take on a regular basis.
In India, as in other Asian countries, it is not customary to use toilet paper, so take it with you if you want to save money and not waste time looking for it in markets.
The sun in India is quite hot, so don't forget your sunscreen.
Food in India is very spicy and if your stomach is not used to eating such food, then it is better to take food with you something from the category of doshiraks. But this is not necessary. If you search well and do not limit yourself to the menu, but ask questions to the employees of cafes and restaurants, then you will always find chicken broth, potatoes with salad without spices. And, of course, tortillas.
