This advice comes as The Met Office has indicated there is a 80% probability of high temperatures between Wednesday and Friday.
Dr Hasan Chowhan, a GP in Colchester and chairman of NHS North East Essex Clinical Commissioning Group, said: “While the hot weather will be welcomed by many, some people will find the higher temperature makes them feel uncomfortable or affect their health. Older people and people with pre-existing medical conditions, such as asthma, diabetes or heart disease are more vulnerable to both the effects of heat and complications of coronavirus.
“While taking care of yourself, try and check on family, friends and neighbours who are on their own, while respecting social distancing guidelines. Older people often experience a reduced sensation of thirst, meaning they don’t realise they need a drink. And dehydration in older people can cause dizziness and light headedness and is a major cause of falls.
“Don’t rely on an older person telling you they are thirsty, instead ensure they are having a drink at specific times of day whether they are thirsty or not. If you’re not living in the same household check in with them by telephone or online, to be sure they’ve been drinking water, tea, coffee or fruit juice regularly to keep them hydrated.
“The symptoms of dehydration include sluggishness, confusion, dizziness and dark urine.”
Dr Mark Shenton, a GP in Stowmarket and chairman of NHS Ipswich and East Suffolk Clinical Commissioning Group, said: "Please don’t let the bright sunny weather give you a false sense of security – coronavirus is still with us so it is important to adhere to social distancing guidelines, wash your hands regularly, cough into a tissue and avoid touching your face.
“When it’s hot we should all be drinking water regularly. Try and avoid going out during the hottest part of the day, usually 11 a.m. - 3 p.m., and leave strenuous activities such as DIY or gardening for when it is cooler. If you have to go out, wear a hat, walk in the shade and apply sunscreen.
"Lying in the sun might be tempting after spending so much time indoors lately, but please stay alert to the dangers of sunburn and remember that sunburn increases your risk of skin cancer.
“For parents, if you have a baby less than six months old, keep your child out of direct sunlight and older infants should also be kept out of the sun as much as possible. Attach a sunshade to your baby’s pushchair, make sure your child wears a sunhat and apply a sunscreen with an SPF of at least 30 to your baby’s skin.
“And please remember, if you use an asthma inhaler don’t leave it in direct sunlight or somewhere it could get hot, such as a car glove box. This could prevent it working properly.”
