Sustainable living treads lightly on natural resources and follows a rethink, reuse, repurpose mantra to minimize waste.

Big and small wallet-friendly tips can help you save money and befriend our planet this summer, says Dr. Wynne Armand, a primary care physician at Harvard-affiliated Massachusetts General Hospital, and associate director of the Mass General Center for the Environment and Health. Here are five great tips to get you started.

1. Embrace the 5 Rs

Refuse, reduce, reuse, repurpose, and only then recycle is a well-laid out sustainability strategy promoted online by the Cincinnati Recycling and Reuse Hub. Do you really want or need a shiny new object? Where can you share tasks or tools? What could you swap, give away, or buy used? How could you slim down your recycling stream?

Give yourself permission to start here: Nobody is perfect. We all have preferences and sustainability blind spots, fumbles, and “sorry, just no” feelings. Start where you are and add on when you can.

2. Cut down on cooling energy

Summer heat can endanger your health, and paring back on energy use isn’t always possible or wise. Still, it may be possible to:

• Stay cooler naturally. Pull down shades during daytime hours to block out hot sun. Open windows at night if the temperature cools down, and to capture cross breezes if possible. Dress in loose cotton clothes and wear a shading hat when outdoors. Remember that sun bounces off lighter colors and is soaked up by black or darker colors. Make your own shade by carrying an umbrella on sunny — not just rainy — days. “Prepare meals that don’t require cooking or baking, since that saves resources and keeps your home cooler,” advises Dr. Armand.
• Seek shade and cool spots. If you don’t have air conditioning or you worry about the bills, green, leafy spaces like parks can help cool you down. Cities and towns often open cooling centers, splash pads, and public pools. Public buildings like libraries and malls are available during daytime hours for anyone trying to beat the heat.
• Turn up the temperature. On air conditioning, that is. If you’re fortunate enough to have air conditioning at home, follow natural cues. When you’re shivering, sweater-seeking, or tucked up under blankets, push the temperature up to save energy and money.

3. Save resources

A sharp eye for energy savings may help pare down bills, too.

• Electrify. Shrink your carbon footprint and help cut air pollution by using electric grills, mowers, and other landscaping tools. When tools or appliances need to be replaced, consider electric options.
• Conserve energy. Turn off electrical equipment that is not in use in the office and at home, such as lights, TVs, computers, copiers, and printers. 
• Go low when demand is high. “During peak electricity demand, ensuring stability of the grid is essential to public health,” says Dr. Armand. “Avoid using appliances like dishwashers, washers, or dryers during periods of high demand. Instead, do these chores — and charge your electric car, if you have one — late at night.” Some energy-hogging appliances have timers to help with this.
• Sign up for Shave the Peak alerts. Know when to curb your electricity use to avoid times when your local electric grid is relying on nonrenewable, expensive, polluting fossil fuels.

4. Stay heat-aware and hydrated

Saving resources is a worthy goal, but not at the expense of staying safe and healthy when summer temperatures spike.

• Make plans to stay cool. When summer swelters, having an affordable, personal plan to cool down — especially during heat waves — can be lifesaving.
• Watch out for signs of dehydration. Drinking plenty of water and eating water-rich foods like lettuce, cucumbers, melon, and citrus fruits can help you stay well hydrated. Water-filling stations for reusable bottles cut down on single-use plastic bottles and help save money at the grocery store.
• Know how to treat heat rash and more serious heat-related illnesses. The small, itchy red or darkened bumps of heat rash (prickly heat) occur when sweat ducts become blocked or inflamed. This makes it harder for children and adults to cool their bodies down. Generally, too much heat can harm our bodies, particularly if we work outdoors, take certain medicines, or have certain illnesses.

5. Kickstart sharing circles

Sharing circles can help you expand a wardrobe, tool shed, or taste in foods — all while building community.

• Start local, then consider expanding. Brainstorm with a few friends on what you all might like to share or swap. Think seasonal: gardening tools, outside décor, summer sports (because not everyone needs to own a paddleboard). Local clubs, block associations, or public spaces like libraries and schools may be willing to host community swaps and shares. Some communities have swap sheds and some libraries loan gadgets and even appliances like a portable induction cooktop burner, tech and home-improvement tools, games, and much more.
• Summer supper club. Perfect for those overloaded with summer harvests from window boxes, community gardens, or a CSA share. Build a theme around what’s fresh, local, and low-cost. Plant-forward menus are good for health and for the planet. Cultural inspiration always helps. And having one person cook — or stressing no-cook recipes — saves resources.
• Cut your clothing allowance. Tired of your wardrobe? Gather friends for a summer clothes and accessories swap. Be sure to agree on rules: gently-used, carefully washed, no stains, and so on.
• Hot spots. “Gathering at a friend’s or neighbor’s home for fun games and festivities on hot days is a great way to build community while saving on energy costs for cooling. And rotate for that next hot day!” says Dr. Armand.

Each year, more than 4.5 million dog bites occur in the United States. Despite what you might assume, most of these incidents don’t happen when an unfamiliar dog attacks someone in a park or another outdoor location. Instead, most dog bites are inflicted by a pet dog in a home.

Here’s advice for avoiding these upsetting and potentially serious injuries — and the steps you should take if you sustain a dog bite.

Why do dog bites happen?

Some dog bites happen by accident when people wrestle or play tug-of-war with their dog. But most of the time, dogs bite people as a reaction to feeling stressed, threatened, scared, or startled, according to the American Veterinary Medical Association (AVMA). More than half of dog bites occur in children, and they’re far more likely to be seriously injured than adults.

“People don’t always heed the behavioral signals that a dog is uncomfortable,” says Dr. Christopher Baugh, associate professor of emergency medicine at Harvard Medical School. For example, some dogs are highly territorial and will bark, growl, snap, and lunge if outsiders enter their space — whether that’s an apartment, yard, or crate. Or dogs may exhibit resource guarding, which shows up as anxious, aggressive behavior around food, toys, or beds.

“These situations can be high-risk, and children in particular have less awareness of that risk,” says Dr. Baugh, who has children and two mixed-breed rescue dogs, Harley and Roxi.

What can you do to prevent dog bites?

Any dog — even a sweet, cuddly dog — can bite if provoked, according to the AVMA. Never leave young children alone with a dog without adult supervision. And teach children to never disturb a dog while it’s eating, sleeping, or caring for puppies.

In a study of 321 facial dog bites treated at Harvard-affiliated Massachusetts General Hospital over a 20-year period, 88% of the bites were from known dogs. Most were in adults and occurred after playing with the dog, feeding the dog, and placing their face close to the dog. However, the hand (usually a person’s dominant hand) is probably the most common location for a dog bite in an adult, says Dr. Baugh.

Other tips from the CDC to prevent dog bites include the following:

• Always ask a dog’s owner if it’s okay to pet their dog, even if the dog appears friendly.
• Make sure the dog sees and sniffs you before reaching out to pet it.
• Don’t pet a dog that seems to be hiding, scared, sick, or angry.

What if an unfamiliar dog approaches you? Remain calm and still, avoiding eye contact with the dog. Stand with the side of your body facing the dog and say “no” or “go home” in firm, deep voice. Wait for the dog to retreat or move yourself slowly away.

What should you do if you’re bitten by a dog?

Clean the wound with mild soap and running water, then cover it with a clean bandage or cloth. Some online resources recommend applying an antibiotic ointment or cream. But these products are recommended only for people with clear evidence of an infection, such as redness, pus, pain, swelling, or warmth, according to the American Academy of Dermatology.

If the injury is serious — with a bite on the face, heavy bleeding, or a possible broken bone — go to the emergency room. That’s also a good idea if you’re bitten by an unknown or stray dog, in the rare event that you might need medicines to prevent rabies (rabies post-exposure prophylaxis).

“Often, people are shocked after being bit and will understandably focus all their attention on their wound,” says Dr. Baugh. The dog’s owner may check in to see if you’re okay, but then walk away. But you should get the person’s contact information and make sure the dog is vaccinated against rabies, he says.

Keep in mind that:

• Emergency rooms are often crowded with long waits, so an urgent care clinic is a good option if the injury doesn’t require immediate attention.
• Some wounds require stitches, ideally within 12 to 24 hours.
• The doctor may prescribe antibiotics to prevent possible infections, especially if you have health problems such as a weakened immune system or diabetes.
• You may also need a tetanus booster if you haven’t had one in the past 10 years. If your vaccine history isn’t available or you can’t remember, you’ll get a tetanus booster just in case.

What if a dog bite is less serious?

Let’s say you have a less serious bite from a family dog known to have a current rabies vaccine. Bites that don’t require stitches can be cleaned with mild soap and running water, then evaluated by your regular health care provider. They may tell you to simply monitor the wound for signs of infection.

“Doctors are trying to be more thoughtful about prescribing antibiotics and limit their use in low-risk situations, because overuse contributes to antibiotic resistance and exposes people to potential side effects without any benefit,” says Dr. Baugh.

Before going any further, here’s the main thing parents should know about swimming lessons: all children should have them.

Every year, over 4,500 people die from drowning in the United States — and, in fact, drowning is the leading cause of death for children ages 1 to 4. Swimming lessons can’t prevent all of those deaths, but they can prevent a lot of them. A child doesn’t need to be able to swim butterfly or do flip turns, but the ability to get back to the surface, float, tread water, and swim to where they can stand or grab onto something can save a life.

10 things parents should know about swimming lessons

As you think about swimming lessons, it’s important to know:

1. Children don’t really have the cognitive skills to learn to swim until they are around 4 years old. They need to be able to listen, follow directions, and retain what they’ve learned, and that’s usually around 4 years old, with some kids being ready a little earlier.

2. That said, swim lessons between 1 and 4 years old can be useful. Not only are some kids simply ready earlier, younger children can learn some skills that can be useful if they fall into the water, like getting back to the side of a pool.

3. The pool or beach where children learn must be safe. This sounds obvious, but safety isn’t something you can assume; you need to check it out for yourself. The area should be clean and well maintained. There should be lifeguards that aren’t involved in teaching (since teachers can’t be looking at everyone at all times). There should be something that marks off areas of deeper water, and something to prevent children from getting into those deeper areas. There should be lifesaving and first aid equipment handy, and posted safety rules.

4. The teachers should be trained. Again, this sounds obvious — but it’s not always the case. Parents should ask about how teachers are trained and evaluated, and whether it’s under the guidelines of an agency such as the Red Cross or the YMCA.

5. The ratio of kids to teachers should be appropriate. Preferably, it should be as low as possible, especially for young children and new swimmers. In those cases, the teacher should be able to have all children within arm’s reach and be able to watch the whole group. As children gain skills the group can get a bit bigger, but there should never be more than the teacher can safely supervise.

6. There should be a curriculum and a progression — and children should be placed based on their ability. In general, swim lessons progress from getting used to the water all the way to becoming proficient at different strokes. There should be a clear way that children are assessed, and a clear plan for moving them ahead in their skills.

7. Parents should be able to watch for at least some portion. You should be able to see for yourself what is going on in the class. It’s not always useful or helpful for parents to be right there the whole time, as it can be distracting for children, but you should be able to watch at least the beginning and end of a lesson. Many pools have an observation window or deck.

8. Flotation devices should be used thoughtfully. There is a lot of debate about the use of “bubbles” or other flotation devices to help children learn to swim. They can be very helpful with keeping children safe at the beginning, and helping them learn proper positioning and stroke mechanics instead of swimming frantically to stay afloat, but if they are used, the lessons should be designed to gradually decrease any reliance on them.

9. Being scared of the water isn’t a reason not to take, or to quit, swimming lessons. It’s common and normal to be afraid of the water, and some children are more afraid than others. While you don’t want to force a child to do something they are terrified of doing, giving up isn’t a good idea either. Start more gradually, with lots of positive reinforcement. The swim teacher should be willing to help.

10. Just because a child can swim doesn’t mean he can’t drown. Children can get tired, hurt, trapped, snagged, or disoriented. Even strong swimmers can get into trouble. While swimming lessons help save lives, children should always, always be supervised around water, and should wear life jackets for boating and other water sports.

The Centers for Disease Control and Prevention website has helpful information on preventing drowning. The American Red Cross offers an online water safety course for caregivers and parents and water safety videos for children. Many public pools and organizations like Boys & Girls Clubs and the YMCA offer swimming classes for all ages.
