Maybe Sachin's leg was paining due to contractions of nerves. When he took bath with warm water , the heat reacted on his nerves and we know that heat expansion so the heat from warm water expanded the nerves to regular size which relaxed him

pplying ice or heat can provide relief from injuries, aches, and pains, but they shouldn't be used interchangeably. Generally speaking, ice works well after a sudden injury while heat helps to soothe ongoing muscle aches and pains.

Ice works for injuries because it narrows your blood vessels, which helps prevent blood from accumulating at the site of injury, which will add to inflammation and swelling while delaying healing. This is also why elevation is helpful, since it  limits blood flow to the area to minimize swelling.1

A good rule of thumb to remember following an injury is RICE: rest, ice, compression, and elevation. You should generally ice the area for 48 to 72 hours to reduce secondary tissue damage and ease pain.

Ice should be applied for about 20 minutes once an hour. You don't want to use ice longer than this as it could damage your skin or even lead to frostbite. Be sure the ice or gel pack you use can be wrapped around the injured area and even compressed to minimize swelling. You'll want to protect your skin from direct exposure  by applying a cloth or towel between your skin and the ice.

When to Use Heat…

For muscle aches and pains, applying a heat pack will help bring blood flow to the area, which promotes healing and soothes pain while increasing flexibility. As blood flow increases, so does the flow of oxygen and nutrients to the area while waste materials are removed.

Heat also works well for joint pain or as a pre-workout warm-up. Hot gel packs or heated water bottles work well for this and don't pose any of the risks of electromagnetic field (EMF) exposure that most electric heating pads do.

Generally speaking, pain that is chronic and does not involve swelling will respond well to heat treatment. As with ice, you'll want to use a barrier between the heat and your skin, such as a cloth. Apply the heat for 15 or 20 minutes at a time.

You may also want to try alternating heat and cold, which is a strategy often recommended by physical therapists and trainers. Apply heat for 20 minutes then follow immediately with 20 minutes of cold.

Another Way to Use Heat: Hyperthermic Conditioning

Heat-shock proteins (HSPs) are used by your cells to counteract potentially harmful stimulus. Whenever a cell is exposed to an unfriendly environment, the DNA separates in certain regions and begins to read the genetic code to produce these stress proteins.

HSPs are actually beneficial, helping to both prevent and repair damaged proteins. Heat-shock proteins are induced by heat, and this is one reason why sauna use is so beneficial.

According to Rhonda Perciavalle Patrick, Ph.D., increasing your core temperature for short periods, as is done by using a sauna, may offer dramatic improvements to your athletic performance. 

She calls this concept "hyperthermic conditioning," which emerging research suggests has multiple positive effects on your body, from increased endurance to the growth of new brain cells.

Hyperthermic conditioning, or "acclimating yourself to heat independent of aerobic physical activity through sauna use," boosts endurance because it induces adaptations in your body that make it easier for you to perform when your body temperature is elevated.

In short, as your body is subjected to reasonable amounts of heat stress, it gradually becomes acclimated to the heat, prompting a number of beneficial changes to occur in your body
