Heat stroke during exercise is a rapid uncontrolled rise in body temperature that can cause you to pass out and can even kill you.

As a result, by 2017, many people took aspirin with the belief that they were helping to prevent heart attacks.

A recent analysis of 86 studies found that "there is no association between nuts and weight gain, and in fact some analyses showed higher nut intake associated with reductions in body weight and waist circumference. The researchers from University of Toronto noted that even though nuts are concentrated sources of fats, "The physical structure of nuts may also contribute to fat malabsorption due to the fat content in nuts being contained within walled cellular structures that are incompletely masticated or digested."

Competitive athletes train by "stressing and recovering," and healthy people who do not compete in sports can gain greater benefits from their exercise programs by using this same training principle. You have to damage muscles to gain strength and enlarge muscles. You become more fit if on one day, you stress your muscles by taking a hard workout, and then letting your muscles recover by exercising at a very slow and relaxed pace with reduced force on your muscles, for as many days as it takes for your muscles to feel ready for another hard workout.
