Dr Amir Khan, a familiar face on ITV's Good Morning Britain and Lorraine, has explained the scientific reasons why women often feel hotter than men during the UK heatwave. In a TikTok clip, he stated that women are not being dramatic but factual about feeling the heat more intensely.
Hormonal and Physical Factors
Dr Khan highlighted that hormones like estrogen and progesterone affect how the body regulates temperature, and menopause can worsen hot flushes. He also noted that women typically have smaller bodies and less blood volume, making it harder to move heat from the core to the skin. Smaller hearts and narrower blood vessels can make heat dissipation less efficient.
Skin Temperature and Iron Deficiency
Research suggests women often have higher skin temperature but lower core temperature than men, causing discomfort even when not overheated. Dr Khan added that women are more prone to iron deficiency due to periods, which can lead to dizziness and exhaustion in hot weather. He also mentioned that sleep disruption during perimenopause and menopause is exacerbated by heat.
Dehydration Risks
Women's smaller frames make them more susceptible to dehydration from sweat loss. Dr Khan explained that a litre of sweat affects a petite woman more than a large man. He encouraged women to complain about the heat if needed, as it is biological.
Tips to Stay Cool
The government recommends avoiding sun between 11am and 3pm, using sunscreen, wearing a hat, keeping curtains closed, limiting strenuous activity, staying hydrated, and using cool packs.
