There are scientific reasons why a room temperature of around 65°F (18.3°C) is optimal for good nighttime sleep. This relates to your body's internal temperature regulation. Your body's internal temperature shifts during a 24-hour period. This is known as a circadian rhythm.

Excessive sweating. Some people with fibromyalgia perspire heavily and may even believe they have a fever. This is due to what's called an autonomic dysfunction within the hypothalamus, the almond-sized area in the brain that controls sleep and regulates sweating, bowel movements, and other automatic body functions.

Temperature fluctuations at night are completely normal. In fact, it's part of your body's circadian rhythm or internal clock, helping to control your sleep/wake cycle. Thanks to various hormones, your body's core temperature drops in the evening ready for sleep.

But probably the main reason fever seems worse at night is because it actually is worse. The inflammatory response mechanism of the immune system is amplified. Your immune system deliberately raises your body temperature as part of its strategy to kill the virus attacking you.

Your body reacts and heats up The increase in these white blood cells affects your hypothalamus. This makes your body heat up, causing a fever. In the early stages of a fever, you often feel cold and start to shiver. This is your body's response to a rising temperature.

Untreated, heat exhaustion can lead to heatstroke, a life-threatening condition that occurs when your core body temperature reaches 104 F (40 C) or higher. Heatstroke requires immediate medical attention to prevent permanent damage to your brain and other vital organs that can result in death.

For instance, alcohol makes one's body warm inside but expands blood vessels thus causing rapid heat loss and diminishing the natural shivering response of the body system. This can result in hangover chills which may be followed by a fever.
