WATCH: Health warning as heatwave grips Cornwall

The Met Office has put out a health warning as Cornwall remains in the grip of a heatwave.

According to the Met Office, temperatures could hit 30 degrees in some parts of the Duchy between now and Wednesday.

Parts of Kernow were reportedly hotter than the tropics on Saturday and Sunday.

Sue tweeted Pirate FM to say: "I live in Barbados and you're hotter than we are! Keep it going - I'm coming over in September".

The Met Office says there is a 90% probability of heatwave conditions until Wednesday morning.

On Saturday morning, its Heat Health Watch service issued a level three amber alert for a heatwave, which means "heatwave action" and a heatwave is happening in some areas.

Its website says: "Very warm or hot conditions are expected with fine and sunny weather, and light winds.

"Regional temperature threshold values are likely to be approached across most regions away from the northwest, and exceeded in some eastern locations during Sunday and Monday.

"Light airflow and high humidity will make night times feel very muggy.

"Some fresher conditions look likely to spread to some northeastern areas on Tuesday for a time.

"The Heat-health watch may be updated again as we move through the hot period".

Pollen may be quite an issue if you're heading out today, and remember to slap on that sun cream as UV levels are also very high for many %u2600%uFE0F pic.twitter.com/7k9OsPsNm7

NHS Choices has this advice for coping with the heat:

• Shut windows and pull down the shades when it is hotter outside. You can open the windows for ventilation when it is cooler.
• Avoid the heat: stay out of the sun and don't go out between 11am and 3pm (the hottest part of the day) if you're vulnerable to the effects of heat.
• Keep rooms cool by using shades or reflective material outside the windows. If this isn't possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).
• Have cool baths or showers, and splash yourself with cool water.
• Drink cold drinks regularly, such as water and diluted fruit juice. Avoid excess alcohol, caffeine (tea, coffee and cola) or drinks high in sugar.
• Listen to alerts on the radio, TV and social media about keeping cool. 
• Plan ahead to make sure you have enough supplies, such as food, water and any medications you need.
• Identify the coolest room in the house so you know where to go to keep cool.
• Wear loose, cool clothing, and a hat and sunglasses if you go outdoors.
• Check up on friends, relatives and neighbours who may be less able to look after themselves.
