5 September 

The UK Health Security Agency (UKHSA) and the Met Office have issued a amber heat-health alert (HHA) for the South East Region, including the Island.

The alert is in place between 12noon on Tuesday 5 September to 9pm on Sunday 10 September across Hampshire and the Isle of Wight and has been updated following the yellow heat health alert issued yesterday (4 September). 

Under the new HHA system introduced by UKHSA and the Met Office, a amber alert means that hot weather has the potential to impact the whole population, both young and old. However babies, pregnant women, the elderly and those with pre-existing long term health conditions, such as respiratory and cardiovascular diseases, are particularly vulnerable to the effects of heat.

Advice for keeping yourself and others safe and well during periods of hot weather:

Stay out of the heat

Keep out of the sun between 11am and 3pm - if you have to go out in the heat, walk in the shade, apply sunscreen and wear a hat and light scarf Avoid extreme physical exertion
Wear light, loose-fitting cotton clothes


Cool yourself down

Have plenty of cold drinks, and avoid alcohol, caffeine and hot drinks, and eat cold foods, particularly salads and fruit with a high-water content
Take a cool shower, bath or body wash, or sprinkle water over the skin or clothing, or keep a damp cloth on the back of your neck


Keep your environment cool

Keep your living space cool - place a thermometer in your main living room and bedroom to keep a check on the temperature
Keep windows that are exposed to the sun closed during the day and open windows at night when the temperature has dropped - close curtains that receive morning or afternoon sun
Turn off non-essential lights and electrical equipment - they generate heat

What to do if you or someone you know is unwell

Dehydration, heat exhaustion and heatstroke can affect anyone during a heatwave, even people who are usually fit and well. Babies, young children, older people aged 65+, and people with underlying health conditions are particularly vulnerable to the effects of hot weather.

Those who work outdoors should try to stay out of the sun and take measures to protect skin against sun exposure, keep cool and stay hydrated.

For more information on heat-related illnesses and what to do should you or someone you know feel unwell visit NHS website. Call NHS 111 or a GP if you or someone you know is unwell. Call 999 in an emergency.
