High blood pressure does not take a holiday in the summer and can even worsen when temperatures rise. Managing hypertension in the summer’s heat and humidity may be harder than you realize. The increasing effects of hot weather on heart health become evident as temperatures rise, and the heat affects your health, including dehydration, dizziness, and heatstroke. 

For patients with high blood pressure, putting additional strain on the cardiovascular system from increased heat may turn a beautiful summer day into a matter of life and death.

Summer is a period of great fun for many people; the longer days, the holidays, and the sunshine. However, you also have to accept the challenges of summer, especially if you are managing high blood pressure. If you ever wonder how to manage blood pressure in the summer heat without putting your health at risk, you are not alone. 

The good news is that some simple precautions and lifestyle changes can help. In this blog, we will break down the important summer health tips for heart patients, share helpful tips to stay cool through the summer months, and provide you with expert recommendations to help you enjoy the summer while managing your blood pressure.

Understanding High Blood Pressure in Summer

Hypertension, or high blood pressure, is a long-term condition in which the force of your blood against your artery walls is consistently too high. Nicknamed “the silent killer,” hypertension most often has no symptoms at all, and if not treated, can silently increase your likelihood of having heart attacks, strokes, kidney diseases, and other lethal conditions.

When summer hits, your body has to work hard to keep your internal temperature in the healthy range. That hard work can also lead to some interesting effects on your cardiovascular system, especially if you are already living with hypertension. Here’s how hot weather affects your heart health:

Dehydration from sweating: 

You sweat more in the hotter months and lose more fluids in your body, which lowers the blood volume in the body, making you more susceptible to quick changes in blood pressure.

Vasodilation (widening of blood vessels): 

One of the ways to cool down your body is to widen your blood vessels, bringing a lower BP temporarily, but could cause instability as your heart is already under stress.

Heat stress: 

Heat can stimulate the release of stress hormones like adrenaline, potentially creating sudden increase in blood pressure. 

Medication sensitivity: 

Some blood pressure medications, especially diuretics, stimulate dehydration, making managing hypertension during the summer even worse because the overall fluid balance in the body is compromised.

How to Control Blood Pressure in Summer: Your Go-To Guide

1. Maintain Hydration Consistency 

Being dehydrated is one of the main causes of summer BP spikes. Water is critical not only for cooling your body down, but it is also necessary to maintain blood volume and blood pressure.

Here are some helpful hints:

– Drink a minimum of 8-10 ounces of water a day, or more if you are sweating a lot.

– Bring a water bottle with you when you are out.

– Eat foods that contain water, such as cucumbers, watermelon, oranges, and tomatoes.

– Stay away from caffeine and sugary drinks. These tend to add to the level of dehydration.

2. Minimize Outdoor Activities During Peak Heat

If you have high blood pressure, manage your daily schedule wisely. Vitality and risk are often maximized between 11 am and 4 pm.

Try these alternatives:

– Exercise in the early morning or after sunset.

– Dress in light, airy and breathable clothing, and wear a sun hat or use an umbrella.

– Rest frequently, preferably in a shaded place, or better yet, an air-conditioned location.

3. Check the Medications for Blood Pressure Management

The summer months can obviously change how your body reacts with respect to certain medications. Some blood pressure pills, particularly diuretics, may enhance risk of dehydration or risk of electrolyte abnormality. 

Some Smarter Moves:

– Talk with your physician about the possibility of adjusting dosages or changed medications if necessary. 

– Do not skip or adjust your own medicine – even if your BP seems to be “normal.”

– Store medications nicely away from any heat so they do not degrade. 

4. Mind Your Meal Selection: Healthy Summer Eating Habits

The food you eat can either help or hurt your hypertension control, especially during the summer when your appetite and digestive function may change.

Summer Heart-Healthy Eating Suggestions:

– Eat light meals such as those that include plenty of fruit, salads, whole grains, and lean protein.

– Avoid high-sodium foods like pickles, papads, and canned soups.

– Use herbs and lemon juice for flavour instead of salt.

– Reduce red meat, fried food, and highly processed foods.

Effects of Hot Weather on Heart Health: What You Need to Know

High temperatures affect more than your comfort,  they affect how your heart operates. The heart has to work harder to pump blood to the surface of the skin to eliminate heat. This can trigger significant events for individuals with heart disease or high blood pressure.

Heat could:

– Heat exhaustion or heat stroke, being over the age of 60, increases risk.

– Irregular heartbeats due to fluid imbalance.

– Sudden drops or spikes in blood pressure, which can leave you feeling dizzy, weak or faint.

– Higher temperatures lead to higher heart rates and further stressed cardiovascular systems.

If you ever feel light-headed, nauseous or excessively fatigued while you’re in hot weather like now, make it a red flag; particularly if you have previously been diagnosed with hypertension.

Managing Hypertension During a Heatwave

Your body has to work harder when temperatures go up, and if you have high blood pressure, it can take a toll. The most important aspect of avoiding trouble due to the summertime heat is to anticipate problems. Controlling hypertension over a heat wave involves being well-hydrated, avoiding hot direct sun for extended periods of time, being cool with lightweight clothing and air circulation, and constantly checking your blood pressure and taking your medication as prescribed. With small adjustments to your daily routine, you can have peace of mind in protecting your heart from health risks when temperatures rise.

Here’s a summer action plan if you are living with high blood pressure:

Everyday Practices that Impact High BP:

– Take your blood pressure periodically, particularly after your outdoor activity.

– Regularly use a home blood pressure monitor; spot the irregularity before it leads to extremes.

– Avoid alcohol and smoking, both will dehydrate your body.

– Learn to manage stress through relaxation techniques such as yoga, deep breathing practice, and meditation.

Sunscreen, Sleep, and Sensible Decisions:

– Employ sunscreen to avoid a sunburn, which will also add stress to the body.

– Work towards 7–8 hours of quality sleep; this can be a challenge in the heat, so utilize fans, cotton sheets, and blackout curtains.

– Avoid sharp changes in temperature, don’t move from extreme heat into an air-conditioned ice-box of a room; give your body time to adjust.

Special Summer Health Tips for Heart Patients

If you live with heart disease, this summer will be a time to be extra careful. Here are some helpful tips to help you thrive:

Hydration:

– If lots of sweating occurs, add a dab of salt and sugar to water (or as advised). 

– Coconut water and buttermilk are natural and excellent hydrating options.

Clothing & Comfort:

– Wear cotton, linen, and loose-fit clothing that keeps you cool. 

– You do not want tight belts or any clothing that restricts blood flow. 

Signs to Seek Emergency Care (Do Not Ignore)

If you are a patient with heart disease or are with a patient with heart disease, and you’re experiencing any of the following symptoms from the heat, get medical help right away:

– Chest pain / discomfort

– Shortness of breath

– Unexplained profuse sweating

– Irregular heartbeat / palpitations

– Confusion, fainting, or sudden weakness

What to Do If You Experience a BP Spike in Summer

If blood pressure suddenly rises, it is important to know what to do, especially outside your normal environment. 

Here are some things to consider:

– Sit somewhere that is shaded, calm, and be sure to take a rest.

– Slowly drink a glass of cool water. I emphasize slowly.

– Reduce your stress level by taking deep, slow breaths. 

– If you are using a prescribed medication for this circumstance, take it; check to see if your doctor advises it. 

– If your high BP does not go down, consider calling your physician, a clinic, or somewhere for help.

While I am reaching people, they often do not realize how difficult high BP can be, both physically and mentally. Respect it; beyond the human condition, prevention is better than cure, particularly in extreme weather situations.

Travelling with High Blood Pressure in Summer? Plan Ahead

If you are travelling, especially to warmer parts of the world, here are some points to consider :

– Take a copy of your prescription and extra drugs with you.

– A portable BP monitor is worthwhile.

– Pay attention to the local weather reports and do not choose a location where the temperature may exceed acceptable levels!

– Stay indoors during the hottest hours.

– Drink a lot of fluids, and eat safe meals with low sodium, avoiding exertion, if possible. 

Having this all in mind helps you enjoy your holiday without jeopardizing your health!
