The duration of a bruise from boxing or any other activity that can cause bruising varies depending on several factors, including the severity of the injury, the location of the bruise, and individual factors. Here’s a general guideline on how long bruises from boxing may last:

• Mild Bruises: Minor bruises from light impacts or glancing blows may fade within a few days, often 5–10 days. These bruises typically change in color from red or purple to green and yellow as they heal.
• Moderate Bruises: Bruises from more significant impacts, such as solid punches or repeated hits, can take a bit longer to heal. They may last anywhere from 10 days to two weeks.
• Severe Bruises: In cases of severe bruising or contusions, which may result from powerful or repeated blows, the bruise can persist for several weeks. It may take 2-4 weeks or longer for the bruise to fully resolve.
• Deeper Tissue Bruises: Bruises that affect deeper tissues, such as muscle or bone, may take longer to heal. These can last for several weeks to a few months, depending on the extent of the injury.

While the visible discoloration of a bruise may fade over time, the underlying tissues may still be healing. It’s advisable to avoid further injury to the bruised area during the healing process to prevent the prolongation of recovery.

The body’s natural healing process involves the breakdown and reabsorption of the blood that accumulates in the bruised area. As this process occurs, the bruise changes color from red and purple to green and yellow and eventually fades. To help promote the healing of a bruise, you can use the RICE protocol (Rest, Ice, Compression, Elevation) in the initial stages to reduce swelling and inflammation. Pain relievers and topical creams may also be used as directed by a healthcare provider.

If a bruise does not appear to be healing, is causing excessive pain, or is associated with other concerning symptoms, it’s advisable to seek medical evaluation to rule out any underlying issues or complications.
