Ice Or Heat? What’s Best?

The best answer to this common question is “It depends on your injury”.  

Inflammation is part of the body’s natural healing response and is actually a positive reaction. With any injury, tissues are damaged, and your body adapts by sending more blood to the injury site. With this increased blood supply, inflammatory cells such as leukocytes and macrophages get to work releasing proteins which clean up and heal the injured site. The area is tender and sore, (which is a reminder for you to be gentle using it!) but your body is effectively trying to repair the damaged area. Keep in mind though, inflammation and pain is your body’s way of telling you to stop and take action. The purpose of inflammation needs to be respected because essentially it is a protective response from the body to prevent you from doing further damage to yourself.

When you apply ice to an injury, the blood vessels constrict, temporarily limiting the blood flow to the injured site. The cold temperature inhibits the pain response, so although ice can often provided some pain relief, it can also delay healing.

When you apply heat to an area, the blood flow increases which can help deliver more oxygen and nutrients to a more chronic problem and support healing. However, for this reason, too much heat can also contribute to further inflammation. Applying heat can help with muscle aches, pains and general stiffness but should never be applied to a new injury or an area that is painful or swollen

So what should you do?

Again, it depends on the injury. If you have a new injury such as a strain or sprain, and you feel you need some pain relief, applying an ice pack is a good option to provide temporary relief (certainly what I recommend more than taking a muscle relaxant or ibuprofen) and it will help the healing process.

Keep these tips in mind:

  • Choose a chemical ice pack, bag of frozen vegetables, ziploc bag with ice cubes in it, and protect your skin by placing clothing or towel between you and the pack
  • 10min on/10min off cycles throughout the day (NOT consistently, your body needs breaks to effectively use the therapeutic benefits. When you apply ice to the injured area you will either feel relief or mild discomfort due to the cold. Often the sensations you feel with icing is pain-tingling-numbness. Once the ice is removed at the 10 minute mark, the area should be numb. The body will then react to re-warm the area with gentle blood flow to supply the tissues with oxygen and nutrients. This reaction will not occur if the ice is left on too long.
  • Ideally ice should be applied as soon as possible after injury, and in cycles for the first 72 hours of acute trauma.

Remember, the body knows best! As far as healing goes it’s best to let inflammation run its course.   This will take time, perhaps even longer than you would like, but ultimately you will be rewarded with improved and more complete recovery.

Cold Water Immersion & Your Health

When cold showers were first mentioned to me as a supportive health practice, my first reaction was “NO WAY”. Like you might be feeling reading this, the thought of being cold was not something that excited me, but at the time I was recovering from an acute muscle strain and I was open to whatever would help me heal the fastest. Now I’m converted.

In addition to supporting your cardiovascular health, regular cold water immersion give you these added benefits:

 

Improves Lymphatic Circulation – Your lymphatic system is an effective network of vessels that essentially cleans up the waste in your body. Unlike your cardiovascular system though, there is no ‘pump’ to keep lymphatic fluids moving well. Your body instead relies on the effective contractions of muscles to support this function (yes this is why you need to be moving your body everyday too).  Cold water immersion helps this process because it causes your lymph vessels to contract, forcing your lymphatic system to pump lymph fluids throughout your body, essentially flushing the waste out of the area. This then triggers the immune system’s white blood cells to attack and destroy any unwanted substance in the fluid. By supporting the lymphatic drainage you’re supporting your immune system, which supports your overall health.

Reduces Muscle Inflammation – When you exercise and push your body to gain additional strength, endurance and power, you’ll develop microscopic tears in your muscles in the process. When the body goes into repair mode you’ll gain new muscle, but the process often involves some soreness known as delayed onset muscle soreness (DOMS). This is normal, but not fun. Cold water immersion has been scientifically shown to help counteract this. Since I’ve been doing cold showers after intense training sessions, the amount of DOMS I experience during recovery has dramatically decreased. This is also something I recommend when people are dealing with an acute injury. Similar to using an ice pack to help control the amount of inflammation, cold water immersion lowers the temperature of the damaged tissue and constricts the blood vessels, which reduces swelling and inflammation. It also temporarily numbs the nerve endings so you’ll feel less pain, which is much better for your body than taking a muscle relaxant or anti-inflammatory medication. If you love physical training, or if you’re dealing with an acute injury, cold water immersion will facilitate faster recovery.

Boosts happiness – I will admit, what keeps me taking cold showers is how great I feel afterwards! Invigorated, energized, and completely refreshed anytime of day.  Cold water triggers a flood of mood-boosting neurotransmitters in your brain, which makes you feel happier. It’s even been shown to be an excellent supportive practice to help reduce symptoms of depression. The science explaining what happens in your body is fascinating, you can read more about it in this article here.

Supports Weight Loss – While nothing replaces healthy clean eating and consistent exercise, consistent cold water immersion boosts your metabolism because your body needs to work harder to keep you warm, burning calories in the process.

If there is ever a season to give this a try, it’s summer!

It’s a great way to beat the heat and quickly cool your body temperature, with so many other added benefits to support your overall health.
