Summary

Central cooling therapy significantly reduced total cholesterol and low-density lipoprotein (LDL) cholesterol in hypercholesterolemia patients. This hydrotherapy intervention involved gradual exposure to cold water over 90 days.

Area of Science:

  • Cardiovascular Health
  • Metabolic Disorders
  • Therapeutic Hypothermia

Background:

  • Hypercholesterolemia is a significant risk factor for cardiovascular diseases.
  • Current lipid-lowering therapies have limitations and potential side effects.
  • Exploring non-pharmacological interventions for managing cholesterol levels is crucial.

Purpose of the Study:

  • To investigate the effects of central cooling (hydrotherapy) on serum lipid profiles in patients with hypercholesterolemia.
  • To assess changes in total cholesterol, LDL-cholesterol, HDL-cholesterol, and triacylglycerols.
  • To evaluate the impact on thyroid hormone levels and body fat mass.

Main Methods:

  • A prospective study involving 68 hypercholesterolemia patients (aged 40-60).

  • A 90-day hydrotherapy protocol involving gradual whole-body exposure to cold water (14-22°C for 5-20 min).
  • Biochemical markers (lipids, thyroid hormones) and body composition were measured at baseline and after treatment.

    • Main Results:

    • Central cooling resulted in a significant reduction in total cholesterol (-0.2 mmol/l) and LDL-cholesterol (-0.2 mmol/l).
    • A significant decrease in tympanic body temperature was observed (0.2-0.8°C).
    • No significant changes were noted in thyroid-stimulating hormone (TSH) or total T3, but free thyroxine (FT4) showed a slight increase in some patients.

    Conclusions:

    • Central cooling via hydrotherapy is an effective non-pharmacological approach to reduce total and LDL-cholesterol in hypercholesterolemia.
    • Body temperature regulation through cold water immersion may offer a novel strategy for managing dyslipidemia.
    • Further research is warranted to explore the long-term efficacy and mechanisms of hydrotherapy in cardiovascular risk reduction.
