Cold and cooling therapy is often used to relieve pain and swelling from injuries such as sprains, strains, bruises and muscle tears. The effect of cold on pain is due to a reduction in blood flow to the injured area, which can lead to reduced swelling and less pain. Cold can also help relieve muscle tension and stiffness.
It is usually recommended to apply cold to the injured area as soon as possible after the injury and repeat it as needed in the first few days after the injury. Cooling should take the form of ice packs, cold compresses, cold showers or other products specifically designed for cooling. It is important to avoid direct contact with the skin and to apply cold at intervals of 20-30 minutes to avoid excessive cold.
It is important to note that cold is not suitable for all types of injuries or pain conditions, so it is important to consult a doctor or physiotherapist for advice on whether it is appropriate in one’s specific case.
