The UK Health Security Agency (UKHSA) has issued guidance on medications that may have a stronger impact during the current heatwave, stressing that hot weather 'can act to worsen existing health conditions.' The agency highlighted that pills taken for mental health issues, such as antipsychotics and common antidepressants like SSRIs, can affect the body's ability to cool itself or retain fluids.
Medications That Increase Heat Sensitivity
According to the UKHSA, medications commonly taken for chronic conditions, including diuretics and beta-blockers, can also alter the body's temperature regulation. The agency advised Brits to understand how their medication affects their response to heat and to reread instructions or consult a doctor or pharmacist if concerned.
Health Conditions Worsened by Heat
The UKHSA explained that when the body tries to cool itself, it puts additional strain on organs already under pressure. People with cardiovascular, respiratory, or kidney problems may experience a worsening of their underlying illness during a heatwave. For example, those with heart disease may find it harder to maintain adequate blood flow, leading to chest pain or heart failure. Similarly, individuals with COPD or asthma may struggle to breathe as hot air, pollution, and dehydration inflame airways and reduce oxygen intake.
Hydration Advice for Vulnerable Groups
People with kidney disease or diabetes should ensure constant hydration, as dehydration increases the risk of acute kidney injury. The kidneys become less able to balance fluid levels in hot weather. The UKHSA urged everyone to remain aware of how existing health conditions and certain medications can affect them during periods of hot weather.
