It is often said that to reduce swelling with ice water is good why

Dizzy, who told you to reduce swelling with ice. You're completely mistaken, there is an S on the 3rd floor who still has to be the head.

First of all, the two friends on the 1st and 2nd floors are very responsible for correcting your mistakes.

When you suffer a sports injury such as a sprain or strain, the first thing to do is to control the injury. Because these injuries are usually under the skin and are tissue bleeding, we often see some athletes using ice packs immediately after injury. In fact, this is hemostasis.

After 24 hours, because the wound is basically healed, a hot compress is used to speed up blood circulation and enhance local metabolism. This is more conducive to reducing swelling, activating blood and removing stasis.

It is worth mentioning that in some fucking idol dramas, there are often some wrong demonstrations, it is better for a girl to twist her foot and fall to the ground, and a boy to rub it when he comes forward, which will only aggravate the injury. After twisting the foot, the first time is a cold compress, and other actions are superfluous.

Within 24 hours of injury, cold compresses are applied because they are mainly for pain relief and to prevent spread.

After 24 hours, you can apply a hot compress to strengthen blood circulation and eliminate blood stasis.

Ice compress is mainly used to reduce swelling and relieve pain, which is more popular abroad and better in the acute stage; Hot compresses are mainly used to invigorate blood and relax tendons, which is commonly used in China, and is better in the chronic phase. However, if there is obvious chills in the sore area, indicating that there is wind chill, it is best to apply a warm compress. In addition, whether it is ice or heat, do not stick the wet towel directly to the meat, otherwise it is easy to become rheumatism (Chinese medicine says that wind cold and dampness are mixed and paralyzed).

Analgesia with cold water! Reduce swelling with hot water!

Cold compresses can constrict capillaries, reduce local congestion, and reduce the sensitivity of nerve endings and reduce pain.

The swelling is due to the accumulation of interstitial fluid, and ice can promote the return of interstitial fluid. Of course, it also has the effect of constricting capillaries.

For the human body, the early physiological effect of ice compress is vasoconstriction, followed by the ischemic effect, which directly affects the oxygen supply and other nutrient delivery of local tissues, and then leads to local tissue necrosis. Normally, the protective effect of the body will prevent this from happening, and our body will notice that the blood vessels here are re-dilated, blood flow increases, and the hypoxia condition improves, thus preventing necrosis. Therefore, long-term ice application is not only dangerous, but also will reduce the effect of ice compress, so the time of ice cracking should be strictly controlled.

Normal ice should not be applied for more than 10 minutes. For more severe injuries, 10 minutes of ice is not enough, so we can use ice every half hour to control symptoms.

Personal supplement: In general, ice is applied in the acute phase within 24 hours of injury, and warm compresses are used in the subacute and chronic phases after 48 hours.

Ice can constrict blood vessels, reduce local congestion, inhibit sensory nerves, reduce pain, relieve symptoms, and have the effects of cooling, hemostasis, analgesia and swelling. And hot compresses are a simple and practical way to ** diseases. The heat dilates the blood vessels, and if the whole body is full of blood, 1 2 to 2 3 blood in the body will accumulate in the body.

Therefore, when the heat is transferred to the blood in the **, the heat will be quickly transferred to other parts of the body, so that the local blood circulation will be accelerated, the content of oxygen in the blood will increase, and the body's metabolic rate will also be accelerated, so it can promote the absorption of local inflammation, so it is better to use ice.

Remember.

The principle of ice to reduce swelling is as follows: ice causes local contraction; Prevents the continued rupture of capillaries; Reduces fluid exudation, reduces and slows histamine release; Reduces the sensitivity of tissues to pain; Reduces exudation and swelling of microcirculation and surrounding tissues; Reduces the action of vascular endothelial cells and the formation of thrombosis; Reduces the release of oxygen radicals and more.

Physiologically, when the temperature drops to 20 degrees, the muscle spindle reflex of the skeletal muscles will be inhibited, muscle tone will be weakened, and pain nerve conduction will also be slowed down or blocked (as low as 10 degrees), resulting in an effective analgesic effect. On the other hand, low temperature strengthens collagen fibers (tendons, ligaments, cartilage, etc.), so that the injured muscles and tendons do not expand later.

Studies have shown that in the first 24 hours after trauma, the microcirculatory disorder and the tissue damage secondary to it are not obvious. So apply ice as soon as possible and for a while.

In this way, early and reasonable ice can achieve the goal of reducing the degree of tissue trauma and speeding up tissue repair.

Swelling is caused by penetration of capillaries or local tissue fluid, and ice compresses cause local constriction to reduce fluid exudation.

The traditional bone-setting medicated wine or safflower oil is rubbed vigorously in the palm of the hand, and it hurts a little at first, but it persists until it becomes hot and swollen. It works well.

Hello friends, generally within 24 hours, if there is swelling, it is recommended to apply a cold compress first, local cooling, to reduce blood circulation, reduce the congestion of damaged muscles, so as to reduce pain and swelling, but if you are more than 24 hours later, there is still swelling and pain, it is recommended that you have better hot compress, capillaries in the platelet repair, capillary wounds will heal, this time swelling is generally caused by congestion, hot compress can speed up blood circulation, Accelerates the dissolution of blood clots in the body, thereby reducing swelling.

The use of external drugs for interventions of a nature** can reduce swelling and pain in the injured area. It is recommended to use the patch to effectively repair the muscles in the injured area, reduce the congestion of the muscles caused by the injury, thereby reducing the degree of swelling, and secondly, the effective ingredients in the patch can effectively inhibit the pain caused by inflammatory factors.

Rest is a must, and after doing the above steps, please be sure to rest so that the damaged area can speed up the healing.

Whether it is a swollen joint or a soft tissue just bleeding, use a cold compress to stop the bleeding and then use a hot compress, but using potato slices is the most effective, the fastest swelling, and it is more effective than using some drugs to promote blood circulation and dissolve stasis, I hope it can help you.

Use a cold compress within 24 hours, you can use a hot compress after 24 hours, if you still have pain for so long, you can go to the hospital for a check-up, if there is no problem, you can take some swelling and pain-relieving drugs appropriately, and then cooperate with hot compress assistance!

Ice is usually applied within 48 hours after surgery to constrict blood vessels. Achieve the purpose of hemostasis. After more than 48 hours, you can apply a hot compress to dissipate stasis and reduce swelling, so you can first apply a warm compress frequently.

If it is swollen, remember not to apply hot compresses first, but cold compresses first. To be fast, this cold compress is very important and will affect your recovery in the future. Hot compress after 48 hours, good luck!

If the face is swollen and use a hot compress, you can use the hot compress to help speed up the blood circulation and metabolism of the local part of the face, so that the excess water accumulated around the eyes can be quickly drained away.

However, if the swelling is caused by trauma, a cold compress is generally applied within 24 hours of the injury to avoid the spread of the swelling, and a hot compress is applied after 24 hours to promote local blood circulation, accelerate local metabolism and the absorption of congestion to achieve the purpose of reducing swelling.

Of course, it's an ice compress, and a hot compress will only get more and more swollen, or rub eggs back and forth
