A warm-up generally consists of a gradual increase in intensity in physical activity (a "pulse raiser"), joint mobility exercise, and stretching, followed by the activity. For example, before running or playing an intensive sport, athletes might slowly jog to warm their muscles and increase their heart rate. It is important that warm-ups be ...
Some take advantage of the refractory period by precipitating an attack by "warming up," and then timing competition such that it occurs during the refractory period. Step-wise training works in a similar fashion. Warm up occurs in stages of increasing intensity, using the refractory period generated by each stage to reach a full workload. [17]
The health and environmental impact of transport is significant because transport burns most of the world's petroleum. This causes illness and deaths from air pollution , including nitrous oxides and particulates , and is a significant cause of climate change through emission of carbon dioxide .
The fastest way to warm your engine up is to use it, aka drive! Some might tell you that the power steering fluid — the oil that pushes on pumps enabling you to control the car's wheels ...

The United States Environmental Protection Agency had issued a 100-page report on global warming and human health back in 1989. [131] [144] By the early years of the 21st century, climate change was increasingly addressed as a public health concern at a global level, for example in 2006 at Nairobi by UN secretary general Kofi Annan.
The health benefits from climate change mitigation are significant. Potential measures can not only mitigate future health impacts from climate change but also improve health directly. [266] [267] Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. [267]
Climate change, fueled by greenhouse gas emissions, has made eerie warmth more likely in states up and down the US. Non-profit group Climate Central said some cities had felt heat 20 degrees above ...
