An increased body temperature made changes to the T-cell membrane to fight certain temperature sensitive viruses or bacteria.
Explanation:
According to medical science, having fever or an increased  body temperature helps the human body to fight certain temperature sensitive bacteria or viruses. 
An experiment performed by the Chinese scientist, Jian Feng Chen of Shanghai Institute of Biochemistry on mice showed that the injected high temperature in the body of the mice stimulated the T-cell membrane which started secreting heat-shock protein or Hsps, which fights stress.  
This study showed that the raised temperature triggers the body immune system to fight a virus or bacteria caused infection.

Dynamic Warm-up:
A good dynamic warm-up is jumping jacks. You jump up, land with your legs about shoulder width apart and arms up, jump again and land with your arms down and legs together, and repeat those steps!
Static cool down:
And good static cool down is low lunges. You  step out really far and lean into your leg, while the other stretches out behind you. Dot the same with other leg, and repeat a few times!
