The Unseen Summer Threat: Why UK Residents Need to Monitor Blood Pressure More Than Ever

Written by Life Pharmacy  »  Updated on: July 31st, 2025 36 views

Summer in the UK may feel mild compared to other places, but it still carries hidden risks especially for your heart. While many people enjoy the warm days, rising temperatures, high humidity, and changes in daily habits can quietly affect your blood pressure. And, if you already have a heart condition or are over 40, you need to monitor blood pressure often.

In this blog, we’ll explain why summer affects blood pressure and how you can easily monitor your blood pressure at home with blood pressure monitors available through online pharmacy UK.

Why Summer Can Be a Problem for Your Heart?

Exposure to Heat

During summer the blood vessels widens and releases more heat which makes your body hot. When your body gets hot, it tries to cool down by sending more blood to the skin. This makes your heart beat faster and work harder.

At first, your blood pressure might drop slightly. But if you stay in the heat for too long without enough water or rest your pressure can suddenly rise again. This puts extra strain on your heart and increases the risk of serious health issues.

Dehydration and Summer Habits

You sweat more during summer which causes your body to lose fluids. If you're not drinking enough water, you can become dehydrated. Dehydration thickens your blood and makes it harder for your heart to pump blood and can raise your blood pressure.

Other common summer habits such as drinking alcohol, eating salty foods, or skipping medication while on holiday can also raise your blood pressure without you realising it.

Heat-Related Illnesses

Prolonged exposure to high temperatures can lead to heat exhaustion or heat stroke. These are serious conditions that can affect anyone, and are dangerous for people with heart disease, high blood pressure, or kidney problems.

Watch out for warning signs such as:

  • Dizziness or confusion
  • Nausea or headaches
  • Muscle cramps or weakness
  • Rapid pulse
  • Cold, clammy skin or excessive sweating
  • Swelling in arms or legs

People Mostly Affected During Summer

While anyone can feel the effects of summer heat, some people are more vulnerable, including:

  • Adults over 50 years of age.
  • People with heart, lung, or kidney conditions
  • People who are on certain medications (like beta-blockers, diuretics, or sedatives)
  • People following low-sodium diets
  • Those who work outdoors or are active in the heat

Why It’s So Important to Monitor Blood Pressure in Summer

High blood pressure, also known as hypertension, often shows no symptoms. You might feel perfectly fine even when your numbers are rising. That’s why it’s sometimes called a “silent killer.” If left unchecked, it can lead to heart attacks, strokes, or kidney problems. Just a small rise in blood pressure can have serious consequences over time.

By checking your blood pressure regularly during summer you can:

  • Spot any changes in your pressure level at an early stage.
  • Adjust your lifestyle or medication if needed.
  • Stay ahead of any serious health risks.

Even a small reduction in blood pressure can significantly help you in decreasing the risk of heart attack or stroke. Moreover, the best part is that you don’t need to visit your GP every time you want to check your blood pressure. You can easily monitor your blood pressure at home with a blood pressure monitor UK. These monitors are easy to use and available through online pharmacy London and supermarkets. Some even connect to your smartphone to help track your readings.

Medications and Summer Heat

Some medications can lose their strength if stored in a hot, humid place. Always store them in a cool, dry spot away from bathrooms, window ledges, or cars. Also, certain medicines may affect how your body handles heat or hydration. If you’re unsure about your medication, speak with your doctor or pharmacist.

How to Stay Safe in the Summer

Here are some simple ways to protect your heart and health during hot weather:

  • Drink water often, even if you're not thirsty
  • Stay in the shade or indoors during the hottest part of the day (11 am to 3 pm)
  • Wear loose, light clothing
  • Avoid too much salt and alcohol
  • Keep taking your medications as prescribed
  • Use fans or open windows to keep your home cool
  • Check your blood pressure regularly, especially if you have an existing condition
  • Apply sunscreen if outdoors and wear a hat
  • Avoid the midday heat and stay inside a cool environment in your home as much as possible
