As the hot weather continues, NHS Corby and NHS Nene clinical commissioning groups are reminding people to take simple steps to stay safe and well.
High temperatures can be dangerous for the elderly, the very young and people with chronic or long-term medical conditions.
As the heatwave continues people are being warned not to go outdoors between 11am and 3pm, the hottest part of the day.
A spokesman for the groups said: “People should spend time in the shade and avoid strenuous activity
“You can help others by checking up on neighbours, relatives and friends who may be less able to look after themselves, for example, if they have mobility problems.”
People are advised to drink plenty water or fruit juice and to avoid tea, coffee and alcohol.
Rooms can be kept cool by closing light-coloured curtains and, if it is safe, open windows at night when the air is cooler.
People with heart problems, breathing difficulties or serious illnesses may find their symptoms become worse in hot weather and they should ensure they have enough medicines in stock and take extra care to keep cool.
The spokesman said: “Heat exhaustion can happen to anyone in hot weather and if it isn’t treated it can lead to heatstroke, which can be dangerous and even fatal.
“If you or anyone else feels unwell, drink water and go somewhere cool to rest. If symptoms such as breathlessness, chest pain, confusion, dizziness, weakness or cramps get worse or don’t go away, seek medical help by visiting your GP surgery, local pharmacy or by calling 111.
“The Met office advice is that the average temperature is going to be 29 degrees on Wednesday and Thursday (July 17 and July 18) with the weather being dry, hot and sunny.
“It is due to get slightly cooler at the weekend and temperatures will rise again early next week.”
