Heat Cramps – When Your Muscles Throw a Tantrum

You’ve been productive. Good for you! Maybe you watered the garden. Maybe you took a gentle walk around the block. Maybe you decided that today was the day to scrub the front porch steps because that moss was starting to look like a shag carpet.

You come inside, feeling proud. You sit down in your favorite chair. You go to stand up five minutes later,

And your calf seizes up like a fist. Or your thigh cramps so hard you yelp loud enough to frighten the cat. What in the name of all that is holy just happened?

You’ve met heat cramps. They are not polite. They do not send a warning card. They just arrive, uninvited and dramatic, like a relative who announces they’re staying for a week.

Here’s the science part, but I’ll keep it short. When you sweat in the Dog Days, you lose not just water but also salt and potassium and magnesium. Those little minerals are what your muscles use to relax after they contract. No minerals? Your muscles forget how to let go. So they stay clenched in a hot, angry knot. It hurts. It’s scary. And it’s completely avoidable.

Heat cramps usually hit the legs, calves, thighs, sometimes the feet or belly. They love to strike an hour or two after you’ve stopped moving. Just when you thought you were safe. Sneaky, right?

Here’s how to send heat cramps packing.

Prevention (the boring but effective part):

• Salt is not the enemy (in moderation). During the Dog Days, a little extra salt, a sprinkle on your scrambled eggs, a few olives, a glass of tomato juice, helps your body hold onto the water you’re drinking. Check with your doctor if you’re on a low-sodium diet, but for most seniors, a tiny bump in salt during heat waves is actually helpful.
• Bananas are your friend. One banana a day keeps the cramp-monster away. Or an orange. Or a handful of nuts. Anything with potassium or magnesium.
• Water alone isn’t enough. If you’ve been sweating for hours, reach for something with electrolytes. No need for fancy neon sports drinks. Coconut water, a glass of milk, or even a small glass of pickle juice (yes, again!) works beautifully.

What to do when a cramp hits (because they will still try):

• Stop. Do not walk it off. Do not stretch aggressively. Stop.
• Gently massage the muscle. Imagine you’re kneading bread dough, but with more swearing allowed.
• Apply a warm towel (not hot) or take a gentle warm bath. I know that sounds backwards, why warm when you’re hot? But the heat helps the muscle relax. Cold can make it clamp tighter.
• Drink something with salt and sugar. A half-teaspoon of salt and a spoonful of honey in a glass of water. It tastes like tears and regret, but it works in fifteen minutes.

If the cramps last more than an hour, or if you’re also nauseous or dizzy, call your doctor. That’s not a simple cramp anymore; that’s heat exhaustion trying to move in.

Otherwise, give your muscle a little pep talk. “Thank you for your service. Now let go, please.” And then tomorrow? Drink that extra glass of water before you scrub the porch. The moss can wait. Your calves cannot.

illnesss caused for seniors by too much heat

Heat can cause several illnesses for seniors, especially during a heatwave when the temperatures are high and last for an extended period of time. Some of the common heat-related illnesses that seniors are susceptible to include:

Heat exhaustion: This occurs when the body is dehydrated and loses salt and other essential minerals through excessive sweating. Symptoms of heat exhaustion include heavy sweating, weakness, fatigue, nausea, vomiting, headache, and dizziness.

Heat stroke is the most dangerous among the heat-related illnesses mentioned and it can be life-threatening if left untreated. Heat stroke occurs when the body's temperature regulation system fails, and the body temperature rises to dangerous levels, typically above 104°F (40°C). This can cause damage to internal organs, including the brain, and may lead to seizures, coma, and even death.

Heat stroke requires immediate medical attention, and treatment typically involves cooling the body to bring down the temperature as quickly as possible. This may involve the use of ice packs, cold water immersion, or evaporative cooling techniques, among others.

It's crucial to recognize the signs of heat stroke and seek medical attention immediately if any symptoms are present, especially for seniors who may be at a higher risk of heat-related illnesses. Heat stroke can be prevented by taking appropriate measures to stay cool and hydrated during periods of high heat and humidity.

Dehydration: This is a common condition that occurs when the body loses more fluids than it takes in. Symptoms of dehydration include dry mouth, thirst, fatigue, dizziness, and dark urine.

Heat rash: This is a skin condition that occurs when sweat ducts become blocked and cause small, itchy bumps on the skin.

Heat cramps: These are painful muscle spasms that occur due to electrolyte imbalances and dehydration.

It's essential to take preventive measures to avoid these heat-related illnesses, especially for seniors, as they are more vulnerable to the adverse effects of heat.

Safety during a heat wave

During a heat wave, seniors are particularly vulnerable to heat-related illnesses such as heat stroke and dehydration. Here are some ways to keep seniors safe during a heat wave:

Encourage seniors to drink plenty of water, even if they don't feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate the body.

Seniors should stay indoors in air-conditioned spaces as much as possible during the hottest parts of the day, usually from 10 a.m. to 4 p.m. If they don't have air conditioning at home, encourage them to go to a cooling center or a friend or family member's home with air conditioning.

Seniors should wear loose-fitting, lightweight clothing made of breathable fabrics like cotton or linen. Avoid dark colours, which absorb heat.

Use fans or air conditioning to keep the home cool. Take cool showers or baths to lower body temperature.

Check-in on seniors regularly, especially those who live alone. Make sure they are staying cool and hydrated.

If a senior shows signs of heat exhaustion or heat stroke such as confusion, dizziness, nausea, or a high body temperature, seek medical attention immediately.

By taking these steps, we can help seniors stay safe during a heat wave.

Heat related illness is dangerous to your health

Heat-related illnesses such as heat edema, heat cramps, heat rash, and heat exhaustion are common among seniors during hot weather. Here are some tips on how seniors can protect themselves from these illnesses:

Heat edema is swelling in the legs and feet caused by prolonged exposure to heat. Seniors should keep their legs elevated as much as possible, avoid standing for long periods, and wear comfortable shoes and clothing that allow for good circulation.

Heat cramps are painful muscle spasms caused by dehydration and loss of electrolytes. Seniors should drink plenty of fluids, especially water and sports drinks that contain electrolytes. They should also avoid strenuous activities during the hottest part of the day and take frequent breaks in the shade.

Heat rash is a skin irritation caused by excessive sweating in hot and humid weather. Seniors should wear lightweight, loose-fitting clothing that allows the skin to breathe, and avoid tight-fitting clothes or synthetic materials that trap heat and moisture. They should also keep their skin clean and dry and avoid using heavy creams or ointments that can clog pores.

Heat exhaustion is a more severe heat-related illness that occurs when the body becomes dehydrated and cannot cool itself down. Seniors should stay well-hydrated, avoid strenuous activities during the hottest part of the day, and seek shade or air-conditioned environments if possible. If they experience symptoms such as weakness, dizziness, nausea, or vomiting, they should seek medical attention immediately.

Seniors should understand the risks associated with heat-related illnesses and take steps to protect themselves during hot weather. This includes staying hydrated, avoiding prolonged exposure to the sun, wearing appropriate clothing, and seeking medical attention if symptoms of heat-related illness occur.

Staying cool outside

Lower your activity level and avoid strenuous activity. If you must do errands or plan to exercise, do so early or late in the day when it is generally cooler. 

Never leave children or pets in a parked car 

Avoid direct sun by staying in the shade and wearing a hat and protective clothing. Use sunscreen and UV-protective eyewear 

Seek cooler, breezier areas when outdoors, such as large parks near trees and water 

If you work in a hot environment, discuss and act on ways to decrease heat exposure with your employer and coworkers

TIP: Pets are part of the family too. Make sure they have plenty of water and are with you in cool locations. When outside, stay in shady areas and avoid asphalt and pavement. Those surfaces can burn paws.

WHAT TO DO IF YOU ARE GETTING TOO HOT

Overheating can be harmful to your health and potentially deadly. If you’re experiencing symptoms such as rapid breathing, rapid heart rate, extreme thirst, and decreased urination with an unusually dark yellow colour, take immediate steps to cool down and seek emergency care:

Get medical attention, or call 911 or your local emergency number

Submerge yourself or the person you’re helping in cool water

Remove clothes and apply wet cloths to the skin

 

STAYING COOL INSIDE

In homes without air conditioning, heat builds indoors over the course of a few days. It may stay hotter inside than outside overnight. Without air conditioning, the longer the heat lasts, the more dangerous it becomes.

Take the following steps to keep yourself and members of your household safe:

·   If you have air conditioning, turn it on. It does not need to be going full strength to help you stay safe

·   If you have air conditioning, and vulnerable friends and family do not, bring them to your home

·   If you do not have air conditioning, move to your pre-identified alternate location with air conditioning or cooler spaces

·   Sleep in the coolest part of the residence. Outdoor temperatures are usually lower than indoor temperatures overnight, so consider sleeping outside if you can safely do so

·   Sleep with a wet sheet or in a wet shirt

·   Take cool baths or showers to draw heat from your body

·   Drink plenty of water, regardless of whether you feel thirsty. Be aware that sugary or alcoholic drinks cause dehydration

·   If you are taking medication or have a health condition, ask your doctor or pharmacist if it increases your health risk in the heat and follow their recommendation

·   If your doctor limits the amount you drink, or has you on water pills, ask how much you should drink while the weather is h
