Sunshine and hot weather put people in the West Midlands in hospital nearly 100 times over the last two summers.
The Met Office has warned that a new heatwave is due to hit parts of the UK this long weekend.
Exclusive figures from NHS Digital show that between April and August in 2017 and 2018, people were hospitalised for heatstroke or exposure to sunlight and natural heat at least 80 times.
In our region, around 45 admissions had a diagnosis of heatstroke.
Heatstroke, or sunstroke, occurs when a person's body temperature has become overheated to a harmful degree and is caused by a failure of the thermostat in the brain which regulates body temperature.
People were admitted to hospital due to exposure to natural heat (but with no diagnosis of heatstroke) around 25 times and because of exposure to sunlight at least 10 times.
Numbers are rounded to the nearest five and figures between one and seven are suppressed to protect the privacy of people.
During the last two summers, people were hospitalised because of the hot weather around 995 times in England.
Of the admissions, around 560 were for heatstroke and around 435 for exposure to sunlight or natural heat.
When people are suffering from heatstroke, the priority is to cool them down as quickly as possible and get them to hospital, according to NHS advice.
Sometimes, people get heatstroke after suffering from heat exhaustion.
Symptoms of heat exhaustion include experiencing a headache, dizziness, loss of appetite, nausea, excessive sweating, cramping, an increased heart rate, a temperature of 38C or above and feeling very thirsty.
In order to cool someone with these symptoms down, is essential to move them to a cool place, get them to lie down and raise their feet slightly, and get them to drink plenty of water, or sports/rehydration drinks.
Spraying or sponging them with cold water and fan them or putting cold packs around the armpits or neck are also effective.
Following these steps should see them start to cool down and feel better within 30 minutes. If they don’t, then their condition may have developed into heatstroke and require emergency treatment.
Ruth May, chief nursing officer for England, said: “Everyone can take simple steps to avoid fun in the sun turning into a holiday in hospital.
“As millions of families kick off the long summer break, it’s really important to take common sense precautions and follow our NHS top tips like drinking plenty of water, using high-factor sunscreen and taking allergy medicine where it’s needed.
“The NHS will be there always for anyone who needs it, but everyone can help by checking in on vulnerable friends and neighbours, while making use of the free, convenient and helpful phone and online NHS services for minor illnesses, to help frontline staff provide care for those in emergency and serious need.”
“People should talk before they walk and join the hundreds of thousands getting fast and free advice on the best course of action for them from the NHS.uk website or 111 phone line.”
