Exercise is painful. As the cliché goes, “No pain, no gain.” When the body exerts itself, pumping action out of muscles to tear them down and build their mass, it’s left with a soreness. Doctors, coaches, and mothers all recommend heat for tense sore muscles—warm baths, moist towels, hot-water bottles, or heated pads as thermotherapy techniques. But how exactly does applying this heat help the pain and relax the muscles?
While exercising, the body requires more energy than it can produce through aerobic respiration, or the intake of oxygen. To create enough energy for vigorous movement, the body goes through another process: anaerobic respiration. This type of energy production burns sugars without oxygen, producing lactic acid within exerted muscles. Overworked muscles and a buildup of lactic acid are what cause the pain associated with exercising. When heat is applied to a sore area of the body, blood vessels widen and blood flow increases to transport excess lactic acid and other toxins away from tired muscles. These muscles are also made more elastic by the heat, and nerve endings are stimulated to block pain signals.

Loneliness and social isolation in older adults are serious public health risks affecting a significant number of people in the United States and putting them at risk for dementia and other serious medical conditions. A report from the National Academies of Sciences, Engineering, and Medicine (NASEM) points out that more than one-third of adults aged 45 and older feel lonely, and nearly one-fourth of adults aged 65 and older are considered to be socially isolated. Older adults are at increased risk for loneliness and social isolation because they are more likely to face factors such as living alone, the loss of family or friends, chronic illness, and hearing loss.
Although it’s hard to measure social isolation and loneliness precisely, there is strong evidence that many adults aged 50 and older are socially isolated or lonely in ways that put their health at risk. Recent studies found that social isolation significantly increased a person’s risk of premature death from all causes, a risk that may rival those of smoking, obesity, and physical inactivity. Poor social relationships (characterized by social isolation or loneliness) was also associated with a 29% increased risk of heart disease. Loneliness among heart failure patients was associated with a nearly 4 times increased risk of death, 68% increased risk of hospitalization, and 57% increased risk of emergency department visits.
