6 Common Causes of Cold Hands and Feet in Summer

Summer is supposed to be hot, yet many people still experience cold hands and feet or feel unusually sensitive to the cold—a sign that may point to an underlying health issue. Under normal circumstances, the temperature of your hands and feet should be close to your body's core temperature. Persistent coldness is worth paying attention to.

  • Poor Blood Circulation
    Prolonged sitting, lack of exercise, or poor posture can make it difficult for blood to reach the extremities, leaving the hands and feet prone to feeling cold. This is especially common among office workers.

  • Anaemia (Iron-Deficiency Being the Most Common)
    Anaemia reduces the blood's oxygen-carrying capacity, leaving the body unable to generate enough heat. This can lead to cold intolerance and cold hands and feet, often accompanied by fatigue, dizziness, and a pale complexion.

  • Hypothyroidism
    The thyroid gland regulates metabolism. When its function declines, the body's ability to regulate temperature also weakens. Aside from feeling cold, patients may also experience weight gain, constipation, and persistent fatigue.

  • Autonomic Nervous System Dysfunction
    Chronic stress, irregular routines, and prolonged exposure to air-conditioned environments can affect the autonomic nervous system, impairing the body's ability to regulate temperature.

  • Hormonal Changes in Women
    Hormonal fluctuations before and after menstruation or during menopause can affect blood vessel constriction, leading to poorer peripheral circulation and a greater tendency toward cold hands and feet.

  • Low Body Fat or Nutritional Deficiency
    Excessive dieting or an unbalanced diet can leave the body without enough energy to maintain its temperature. Those with a low body-fat percentage are particularly susceptible to feeling cold.


Cold hands and feet in summer aren't simply a matter of "feeling the chill"—they may be linked to hormonal, blood, or endocrine issues, and can't be resolved by "wearing more clothes" alone.

 

When Is It a Health Warning Sign? When Should You See a Doctor?

If the chill is only a brief response to overly strong air conditioning, there's generally no need to worry. However, if you experience any of the following, further evaluation is recommended:

  • Cold hands and feet persisting for more than 2–3 months
  • Frequent fatigue, dizziness, or heart palpitations
  • Catching colds easily or weakened immunity
  • Menstrual irregularities in women

These symptoms may be associated with anaemia, thyroid problems, or other chronic conditions. Getting checked early can help you make the most of the optimal window for treatment.

 

Which Health Screenings Are Recommended for Cold Sensitivity in Summer?

If you suspect your sensitivity to cold is related to a health issue, the following tests can help identify the cause:

  • Complete Blood Count (CBC) - Assesses red blood cell and haemoglobin levels, helping to diagnose anaemia and providing insight into your overall health.
  • Iron and Nutritional Level Testing - Including iron, vitamin B12, and folate, this helps determine whether cold sensitivity is due to nutritional deficiency.
  • Thyroid Function Test - Through TSH, T3, and T4 testing, this determines whether the thyroid is functioning normally—one of the key tests for pinpointing the cause of cold sensitivity.
  • Female Hormone Test - Suitable for women experiencing irregular periods or menopausal symptoms, this evaluates oestrogen and progesterone levels.
  • Basic Metabolic and Chronic Disease Screening - Including blood glucose, blood lipids, and liver and kidney function, this can rule out other chronic conditions that affect temperature regulation.

If symptoms persist, consider a comprehensive health check plan that includes blood, endocrine, and metabolic assessments:

Warm Up the Body Appropriately Drinking warming beverages such as ginger tea, red date tea, or longan tea can help relieve coldness in the body.

The right health screening can help identify the cause early and address it appropriately. If you've had related symptoms over the long term, consider getting a blood test or thyroid function test to safeguard your health.
