Wales Braces for Record Heat as Red Alert Issued
Wales is experiencing an unprecedented heatwave, with a rare red alert issued as temperatures are set to break records. Forecasters predict the mercury will climb to 36°C today and 39°C tomorrow, with the possibility of reaching 40°C, making this potentially the hottest June day ever recorded. A rare health warning has been put in place as schools shut their doors and rail services face widespread cancellations and delays.
The Met Office's red warning covers southern England and the Midlands, including London, Somerset and Birmingham. It also extends to parts of Wales, including Swansea and Cardiff, running from 9am today until 9pm tomorrow.
British Red Cross Advises Against Alcohol and Caffeine
Throughout the heatwave, many will find it a struggle to get a decent night's sleep as keeping cool becomes increasingly challenging. The British Red Cross has released guidance on how to stay cool at night to achieve a good night's sleep. They caution against drinking alcohol and caffeine during the heatwave, warning that both can disrupt sleep patterns.
They said: "Alcohol often goes hand in hand with sunny weather but, it is advised to limit consumption especially in the evening but causes poorer quality of sleep." Caffeinated drinks are diuretics and may encourage your body to lose fluids, risking dehydration as well as increase your body temperatures.
Impact on Sleep and Health
According to the NHS, adults typically require between seven and nine hours of sleep per night, with teenagers and babies generally needing more. A lack of sleep can seriously affect overall health, with potential consequences for the immune system, concentration, cognitive function, anxiety and depression.
The British Red Cross added: "Hot weather can often mean your everyday routine goes out the window but, eating and going to bed later may affect the quality of sleep. Try to stick to your usual eating and bed times and keep the same night-time routine." The heat can also mean you feel more tired during the day because your body is using more energy to regulate internal temperature. "Try not to give in to having a day time nap, as this disrupts your sleep pattern and can make it harder to fall asleep in the evening."
Previous Red Alert and Expert Warning
The other red alert heat warning prior to this was issued in July 2022. Prof Robin May, chief scientific officer at the UKHSA, warned that even those in the prime of their life should "take very cautious steps" throughout the heatwave. He described the red heat health alert as one that "signals a very widespread threat" from the heat, encompassing dangers "to people who generally think of themselves as not being particularly threatened by heat."
Speaking on BBC Radio 4's Today programme, he said: "Often we are warning about the vulnerable, the elderly, the young, but in this case we're also warning otherwise healthy people in their prime of life to take very cautious steps, because this heat is going to be quite intense and can have very serious life threatening effects even in people who are completely fit."
