Regrouping and Exercising in Blazing Heat

From the potluck on last week, I didn't do so well and gained a few pounds back. I still suspect that some of that is water weight due to a large amount of salt, and also due to that time of the month (sorry to any guys who might be reading, but that does factor in).

Sometime last week I posted the portion list for phase 2 of South Beach, and I made food choices for this week based on that. One thing I realized is that I needed to up my vegetable quantities for lunch and dinner.

I'm solving that problem by having steamed vegetables for lunch with some sweet Italian chicken sausage and adding different seasoning blends.

Breakfast is some chicken and apple sausage mixed with scrambled eggs and a bit of queso fresco, sautéed squash (mostly from our garden), bell peppers and black beans.

I'm also going to make a really thick and chunky spaghetti sauce with ground turkey and lean ground beef, squash (also mostly from our garden), asparagus, bell peppers, fresh tomatoes from our garden, mushrooms and onions. It'll actually be less like a sauce with some vegetables mixed in and more like a vegetable dish with some sauce added. I'll add a little whole wheat pasta to that and bake it.

The weather here is getting really hot. We're supposed to top 100° again today. Bleah. I hate stinking hot weather. It’s even worse when you live in a house without air conditioning.

I’m still planning to walk this evening. Fortunately, McKinley Park has a lot of trees, so that keeps it from feeling so hot. I did find some tips on exercising in the heat that I wanted to share:
Hot-weather exercise: How to keep cool
Outdoor exercise can be challenging when the temperature soars. Stay safe during hot-weather exercise by drinking enough fluids, wearing proper clothing and timing your workout to avoid extreme heat.

By Mayo Clinic staff

In the excitement of a pickup basketball game or the relaxation of a friendly round of golf, you might not notice the temperature rising — but your body will. If you exercise outdoors in the heat, use caution and common sense to prevent heat-related illnesses.

How hot weather affects your body
Exercising in hot weather puts extra stress on your heart and lungs. Both the exercise itself and the air temperature increase your body temperature. To dissipate heat, more blood circulates through your skin. This leaves less blood for your muscleshotday, which increases your heart rate. If the humidity is high, your body faces added stress because sweat doesn't readily evaporate from your skin — which only pushes your body temperature higher.

Under normal conditions, your skin, blood vessels and perspiration level adjust to the heat. But these natural cooling systems may fail if you're exposed to high temperatures and humidity for too long. The result may be a heat-related illness, such as heat cramps, heat exhaustion or heatstroke.

To keep it cool during hot-weather exercise, keep these basic precautions in mind:

~ Take it slow. If you're used to exercising indoors or in cooler weather, take it easy at first. As your body adapts to the heat, gradually increase the length and intensity of your workouts. If you have a chronic medical condition or take medication, ask your doctor if you need to take additional precautions.

~ Drink plenty of fluids. Your body's ability to sweat and cool down depends on adequate rehydration. Drink plenty of water while you're working out — even if you don't feel thirsty. If you're planning to exercise intensely or for longer than one hour, consider sports drinks instead. These drinks can replace the sodium, chloride and potassium you lose through sweating. Avoid drinks that contain caffeine or alcohol, which actually promote fluid loss.

~ Dress appropriately. Lightweight, loosefitting clothing promotes sweat evaporation and cooling by letting more air pass over your body. Avoid dark colors, which can absorb the heat. A light-colored hat can limit your exposure to the sun.

~ Avoid midday sun. Exercise in the morning or evening — when it's likely to be cooler outdoors — rather than the middle of the day. If possible, exercise in the shade or in a pool.

~ Wear sunscreen. A sunburn decreases your body's ability to cool itself.

~ Have a backup plan. If you're concerned about the heat or humidity, stay indoors. Work out at the gym, walk laps inside the mall or climb stairs inside an air-conditioned building.

Know when to call it quits

During hot-weather exercise, be on the lookout for heat-related illness. Signs and symptoms may include:
~ Weakness
~ Headache
~ Dizziness
~ Muscle cramps
~ Nausea or vomiting
~ Rapid heartbeat

If you suspect a heat-related illness, stop exercising and get out of the heat. Drink water, and wet and fan your skin. If you don't feel better within 60 minutes, contact your doctor. If you develop a fever higher than 102 F (38.9 C) or become faint or confused, seek immediate medical help.

Regular physical activity is important — but don't let hot-weather workouts put your health at risk.
