BBC Doctor Warns of '3pm' Heat Rule

Dr Ranj Singh appeared on BBC Morning Live to talk about the heat.

The UK is very hot, with temperatures possibly reaching 40C, and a red alert has been issued. A BBC expert explained the '3pm rule' to avoid the worst of the heat.

People are buying fans, ice cream makers, and sun cream to deal with the heat. Some stores have seen a big increase in sales of these items.

One store said sales of electric fans were up over 100%, and sales of cool bags and ice cream makers were also up a lot.

A 'heat-dome' is coming to western Europe, which could bring very high temperatures by Wednesday.

A red weather warning has been issued for extreme heat in some areas. Dr Ranj Singh said people often go out at the wrong time.

Dr Ranj Singh said people should be sensible and think about when they go out. The sun is highest between 11am and 3pm, but the heat is highest from 3pm to 5pm.

Dr Ranj said it's very important to check on people who are vulnerable, like the very young or old, and make sure they have what they need.

Dr Ranj said people should look out for heat exhaustion, which happens when you're in the heat for too long. You should cool down and have drinks.

If you can't cool down, you might have heat stroke, which is a medical emergency. You should cool the person down quickly and call for help.

The symptoms of heat exhaustion include feeling unwell and being too hot.

The symptoms of heat exhaustion are the same for adults and children.

If someone has heat exhaustion, they need to be cooled down and given fluids.

The symptoms of heatstroke include a high temperature and confusion.

Heatstroke is a medical emergency and you should get help right away if someone has the symptoms.
