How Your Body Clock Stays on Time Despite Temperature Changes

Researchers uncovered how our biological clocks keep a 24-hour rhythm even as temperatures fluctuate. Using physics-based models, they discovered that at higher temperatures, gene activity rhythms become distorted—rising faster and falling slower—to maintain the cycle’s duration.

Controlling Human Body Temperature to Mimic Hibernation

Researchers have discovered a way to control human body temperature, mimicking the hibernation process of animals like bears. By manipulating the brain’s temperature regulation system, they can induce a state of “thermoregulatory inversion” (TI) in rats, reducing heat production even in cold environments.

Length of REM Sleep Linked to Body Temperature

Study reports warm-blooded animals with higher body temperatures have lower amounts of REM sleep, while those with lower body temperatures have more REM sleep. Researchers say REM sleep acts like a "thermostatically controlled brain heater."

Take a Warm Bath 1-2 hours Before Bedtime to Get Better Sleep

Taking a warm bath an hour or two before bedtime can help improve sleep quality. Scheduling a soak in the tub 1.5 hours before sleep, and setting the water temperature to 104-109 degrees Fahrenheit can hasten the speed of falling asleep by, on average, 10 minutes in addition to improving sleep quality.
