Why Aging Makes You Feel the Cold: Expert Insights and Winter Survival Tips

POLICY WIRE — London, United Kingdom — As winter temperatures drop, many individuals find themselves struggling to stay warm. According to Dr. Elise Dallas, a GP at London General Practice, this increased sensitivity to the cold is often a direct result of the natural aging process.

A primary driver of this change is a slowing metabolism. Dr. Dallas notes that reduced lean muscle mass and hormonal shifts, such as declining thyroid function and lower levels of DHEA, diminish the body’s ability to produce heat. Furthermore, the body’s thermogenesis process becomes less efficient as we age.

Physical composition also plays a significant role. Sarcopenia leads to a loss of muscle mass, which reduces heat generation, while a decrease in subcutaneous fat limits insulation. Additionally, fat tends to redistribute toward the center of the body, leaving the limbs more vulnerable to the cold.

Circulatory changes further complicate the issue. Dr. Dallas explains that blood vessels stiffen and become less responsive, which slows peripheral circulation. This makes it increasingly difficult for the body to deliver heat to the extremities.

Underlying health conditions can exacerbate these issues. Hypothyroidism, anaemia, and diabetes can impair the body’s ability to generate or circulate heat. Heart failure may limit cardiac output, while conditions like Raynaud’s phenomenon cause extreme vasoconstriction when exposed to low temperatures.

Medications frequently prescribed to older adults can also interfere with thermoregulation. Diuretics may cause dehydration, while antidepressants and various vasodilators, such as calcium channel blockers, alpha-blockers, and beta-blockers, can disrupt vascular tone and cardiac output.

Other contributing factors include thinner skin, reduced sweat gland function, and lower physical activity levels. Dr. Dallas warns that cold exposure poses serious risks for older adults, including hypothermia, increased cardiovascular strain, worsened arthritis, and a higher risk of falls due to impaired mobility.

To mitigate these risks, Dr. Dallas recommends wearing thermal layers, including hats and gloves. She suggests maintaining indoor temperatures of at least 20C, utilizing heated blankets, and sealing draughts. Consuming regular, warm meals and staying active indoors are also vital strategies for maintaining circulation and warmth.
