It\u2019s 8:52 AM and 86 degrees Fahrenheit (30 Celsius) where I live in Southern California. My husband just came back from a morning outing with our four-month-old. \u201cHow was the botanic garden?\u201d I ask him. \u201cIt was okay. It was just too hot,\u201d he tells me. I didn\u2019t expect us to spend so much of our son\u2019s first summer cooped up inside, hiding from the heat.<\/p>\n<\/div>\n

\n

As I write this, an extreme heat warning for my area is glaring at me from my phone, effective for at least the next three days. \u201cDangerously hot conditions with high temperatures up to 110 [degrees Fahrenheit] expected,\u201d my weather app warns me. \u201cStay in an air-conditioned room, stay out of the sun.\u201d<\/p>\n<\/div>\n

As I write this, an extreme heat warning for my area is glaring at me from my phone.<\/p>\n<\/div>\n<\/div>\n

\n

It\u2019s the sort of warning more kids are growing up with as global average temperatures climb. Around the world, 560 million children under the age of 10 are experiencing at least one additional month of heat stress each year as a result of climate change, according to a new study<\/a> published in the journal Science Advances<\/em>.<\/p>\n<\/div>\n

\n

\u201cI hope that this increases public awareness that climate change is a problem that is already happening today, that\u2019s already affecting us,\u201d says Rosa Pietroiusti, lead author of the study and a PhD researcher at Vrije Universiteit Brussel<\/a>. \u201cIt\u2019s affecting the health of the most vulnerable.\u201d<\/p>\n<\/div>\n

\n

Pietroiusti\u2019s team used an international standard for moderate heat stress, days when taking protective measures like rest breaks are recommended to prevent heat-related illness. The threshold is set at a WetBulb Globe Temperature<\/a> of 28 degrees Celsius (82.4 F), a measure that takes heat, humidity, wind speed, and cloud cover into account. Thanks to advances in climate attribution science<\/a>, they were able to assess the number of days crossing that threshold and how many of those heat stress days were added by climate change.<\/p>\n<\/div>\n

\n

They found that children are disproportionately exposed to dangerous heat, as compared to older age categories. Climate change has led to at least one additional month of heat stress for 43 percent of all kids in the 0-9 age group \u2014 560 million little ones. That\u2019s nearly triple the number of people aged 60-69 exposed to the same amount of climate-induced heat stress.<\/p>\n<\/div>\n

\n

That\u2019s due to even more socio-political inequity at a global scale; the highest increases in heat stress due to human-caused climate change take place in countries in the Global South that have contributed least to the fossil fuel pollution raising temperatures. These countries have younger populations, and they also tend to have less access to air conditioning or infrastructure designed to withstand extreme weather events. And if countries blow past the targets they agreed upon in the Paris climate accord, the number of children under the age of 10 that are exposed to an extra month of heat stress rises to 650 million with just 2 degrees Celsius of global warming, the new study finds.<\/p>\n<\/div>\n

\n

Heat in particular can sneak up on you because it doesn\u2019t always arrive with the same public safety warnings as a big storm might. And yet it\u2019s a leading cause of weather related deaths globally, according to the World Health Organization<\/a>. Heat stress can lead to dehydration, heat stroke, and eventually organ failure.<\/p>\n<\/div>\n

\n

Babies and kids are even more susceptible than most adults. Their small bodies have a higher surface area-to-body mass ratio that makes it easier for them to overheat. Think of a small ice cube melting in the sun compared to a big block of ice. Babies\u2019 sweat glands are still developing<\/a>, making it even harder for them to regulate their body temperature. They\u2019re totally dependent on adults to take life-saving precautions, like staying hydrated.<\/p>\n<\/div>\n

\n

Heat-related illness is preventable as long as a kid can find a place to stay cool. And we can stop summers from getting even hotter than they already are today by turning to energy sources like solar and wind that don\u2019t emit planet-heating pollution.<\/p>\n<\/div>\n

\n

There are already plenty of ways the heat makes being a new mom even harder than it needs to be. The American Academy of Pediatrics recommends<\/a> that parents avoid taking babies outside for long stretches whenever the \u2018feels like\u2019 temperature reaches higher than 90 degrees Fahrenheit (32.2 Celsius). With this summer\u2019s heatwaves, that meant that my family was mostly stuck indoors from about 11:00 in the morning or earlier until past sunset.<\/p>\n<\/div>\n

\n

My son typically loves walks outside, and spending time outdoors can be especially beneficial for a parent\u2019s mental wellbeing postpartum. I hate that it\u2019s not even safe to explore his grandparents\u2019 backyard after a certain time. Sometimes there\u2019s a doctor\u2019s appointment or groceries to grab midday. That often means blasting the AC to cool down a sweltering car while we wait in a hot parking lot.<\/p>\n<\/div>\n

\n

As irritating as this all is, I\u2019m one of the lucky parents with a car and air conditioning at home. We had a taste of what it would be like without AC when we lost power one hot July afternoon. Power outages<\/a> have grown longer<\/a> in the US as extreme weather has become more common. Heatwaves can trigger blackouts because of electricity demand peaks when people blast the AC, or when utility companies preemptively shut off power lines to keep them from sparking wildfires.<\/p>\n<\/div>\n

Regardless of the weather, breastfeeding is hard!<\/p>\n<\/div>\n<\/div>\n

\n

My family packed up to head to grandma\u2019s house to stay cool, and to save the stash of breastmilk in the freezer (thankfully the lights came back on just before we were about to leave). I calculated, and had the milk gone bad, that would amount to about 20 hours of my time pumping (much of it during sleepless nights) down the drain. I didn\u2019t know this until I was about to become a mom, but newborns shouldn\u2019t drink water. So they might feed more frequently to hydrate. Breastfeeding parents are often thirsty<\/a> because you\u2019re losing fluid<\/a> to your baby, even more so in the heat.<\/p>\n<\/div>\n

\n

Regardless of the weather, breastfeeding is hard! Being a parent is hard! Being a kid gets tough, too. That\u2019s what makes lazy summer days at the beach, and having other outdoor adventures so important. It\u2019s supposed to be an escape, and prime time for core memory-making.<\/p>\n<\/div>\n

\n

Before my baby was born in April, I daydreamed about us lounging at the beach this summer. I couldn\u2019t imagine his face yet, but I could picture those tiny toes in the sand. My son and I did manage to make it to the ocean. A baby\u2019s skin is too sensitive for sunscreen<\/a> until about 6 months old, so he wore his little blue bucket hat for a short walk along the pier. My husband took a quick video of us when I attempted to take him out of the stroller to gaze over the water. He scowls and fusses when the bright sun hits his eyes. \u201cThis is too much?\u201d I ask him. \u201cThis is too much.\u201d<\/p>\n<\/div>\n
