Some infections, like pneumococcal pneumonia and typhoid fever, do not cause significant temperature fluctuations. 2 Endocrine (hormonal) disorders can like hyperthyroidism can also lead to high temperatures. 3 Extremely hot summers with high humidity levels can raise your temperature to abnormal and dangerous levels, as can hot tubs and jogging. This is one reason why it is important to wear natural fibers and light colors in summer, and to wait until after the sun goes down to engage in serious exercise. 4 Even certain medications, drugs, and alcohol can lead to high temperatures, especially when combined with physical exercise.

How does the body lose heat?
Heat is produced during chemical reactions that take place as a part of body metabolism (while producing energy from food) and during physical activities. With the help of radiation (flow of heat from warmer to cooler areas) and sweating, the body tries to lose heat in order to keep itself cool. Evaporation of sweat helps keep the skin cool. Radiation is helpful when the body is warmer than the surrounding environment. High humidity can reduce the effectiveness of sweating because the rate of evaporation of sweat slows down, as the humidity levels increase. This is the reason why the body finds it difficult to lose heat in hot and humid weather. Excessive heat production, ineffective heat loss, or both can lead to heat cramps, heat exhaustion, heatstroke (a serious condition).
