lessen

This verb describes a reduction in intensity or magnitude, often carrying a positive connotation when applied to negative states like pain, stress, or noise. It suggests a gradual decline rather than an abrupt stop, focusing on the process of diminishing a burden or a threat.

It implies a softening of impact or a easing of pressure, making it a common choice in medical or emotional contexts where the goal is relief.
