Ice hockey is a sport that is gaining popularity in India.
Ice hockey is played mostly in places like Shimla, Ladakh and Kashmir in the north of India, where cold weather occurs and the game can be played outdoors.
There are a few artificial indoor ice skating rinks in the rest of the country, which has a warm tropical climate, including the Doon Ice Rink in Dehra Dun, which can accommodate ice hockey with an international-sized rink.
Ice hockey enthusiasts from other places in the country as well as expatriates from abroad head to places like Ladakh for the experience of playing in some of the highest rinks in the world.
In 2011, an Indo-Canadian film, Speedy Singhs based on an Indian ice hockey team was produced by actor Akshay Kumar, who is a fan of the sport.
He also made a contribution to the Ice Hockey Federation of India to encourage greater participation and awareness in the sport.
The India national ice hockey team has been competing at the international level since 2009 with Head Coach Adam Sherlip behind the bench during the tournament in Abu Dhabi, UAE as well as the 2012 tournament hosted by India at the Doon Ice Rink.
Adam also coaches ice hockey in Ladakh through The Hockey FoundationThe country's two oldest ice hockey clubs are the Shimla Ice Skating Club, which has existed since 1920 but began playing ice hockey much later, and the Ladakh Winter Sports Club, which was established in 1935.

According to the Hughston Health Alert, "Lacerations to the head, scalp, and face are the most frequent types of injury hockey."
(Schmidt 6) Even a shallow cut to the head results in a loss of a large amount of blood.
Most concussions occur during player to player contact (49%) rather than when a player is checked into the boards (35%).
Not only are lacerations common, “it is estimated that direct trauma accounts for 80% of all injuries.
Most of these injuries are caused by player contact, falls and contact with a puck, high stick and occasionally, a skate blade.” (Schmidt 3) One of the causes of head injury is checking from behind.
Due to the danger of delivering a check from behind, many leagues, including the NHL have made this a major and gross misconduct penalty (called "boarding").
Another type of check that accounts for many of the player to player contact concussions is a check to the head.
A check to the head can be defined as delivering a hit while the receiving player’s head is down and their waist is bent and the aggressor is targeting the receiving player's head.
Checks to the head have accounted for nearly 50% of concussions that players in the National Hockey League have suffered.
Concussions that players suffer may go unreported because there are no obvious physical signs if a player is not knocked unconscious.
This can prove to be dangerous if a player decides to return to play without receiving proper medical attention.
In recent years there has been debate over whether or not a check to head should be deemed an acceptable hit in hockey.
In March 2011, the NHL instituted a new concussion testing protocol to help improve detection of concussions during gameplay
