Lowering body temperature modestly extends lifespan and may slow aging in animals. This review explores potential biological mechanisms behind this phenomenon in aging research.

Area of Science:

  • Gerontology
  • Physiology
  • Comparative Biology

Background:

  • Body temperature influences metabolic rate and cellular processes.
  • Aging is a complex biological process associated with decline in function.
  • Longevity interventions are sought across diverse animal models.

Purpose of the Study:

  • To review the effects of reduced body temperature on longevity.
  • To explore potential mechanisms linking hypothermia to slowed aging.
  • To consider these mechanisms within established aging theories.

Main Methods:

  • Literature review of studies on body temperature and aging.
  • Analysis of data from poikilotherm and homeotherm models.
  • Synthesis of findings with major aging theories.

Main Results:

  • Consistent evidence suggests modest body temperature reduction extends lifespan.
  • Hypothermia appears to modulate key aging pathways.
  • Mechanisms may involve metabolic rate, oxidative stress, and molecular signaling.

Conclusions:

  • Reduced body temperature is a conserved modulator of longevity.
  • Further research into hypothermic effects can elucidate aging mechanisms.
  • Translational potential for aging interventions exists.
