Hot car heatstroke: how to prevent it (2026)
Short answer: never leave a child in a car, not even for a minute, with the windows cracked or the AC on. Build a habit: put your phone, bag or purse in the back seat, check the whole car before you lock it, and ask child care to call if your child is late. Lock your car when parked and keep keys away from kids; about 1 in 4 hot-car deaths happen when children get in on their own (AAP). If you see a child alone in a car, call 911.

NHTSA[1] says more than 1,000 children have died of vehicular heatstroke over the past 25 years, including 31 in 2025. Over half of these deaths happen when a caregiver forgets a child is in the car. It can happen to any parent.
How fast does a car get dangerous?
| Fact | Source |
|---|---|
| A car can heat up about 20°F in 10 minutes, even with a window cracked | AAP; CDC |
| A child’s body heats 3 to 5 times faster than an adult’s | NHTSA; AAP |
| Organs begin shutting down at 104°F; death can occur at 107°F | AAP; NHTSA |
| Heatstroke can happen with outside temperatures as low as 57°F | AAP |
| Cracking windows, shade or AC barely changes the inside temperature | AAP; NHTSA; NWS |
| Deaths happen year-round | NWS |
Habits that prevent it
- Check the entire car, especially the back seat, every time before you lock it (NHTSA[1]; AAP[2][5]).
- Put your phone, bag, purse or briefcase in the back seat (NHTSA; AAP).
- Keep a stuffed animal in the car seat; move it to the front seat when your child is buckled in (CDC[3]; NHTSA).
- Ask child care to call if your child doesn’t arrive as expected; the AAP suggests if they’re more than 10 minutes late.
- Be extra alert when routines change, like a different driver or route (AAP).
- Lock the car, even in your driveway, and keep keys and fobs away from children (NHTSA; AAP; NWS).
If you see a child alone in a car: act immediately and call 911. A child in distress from heat should be removed and cooled quickly (NHTSA).
Who should skip this, and what to skip
No family should skip these habits. Some newer cars have rear-seat reminders, but the habits work in any car.
- Leaving a child “just for a minute”: AAP[2][5] and NWS: cars heat fast; children can die in minutes.
- Counting on cracked windows or shade: NHTSA[1], AAP[2][5] and NWS: they barely change the temperature.
- Leaving a parked car unlocked: AAP[2][5]: about 1 in 4 hot-car deaths happen when children lock themselves in.
The free or budget option
Every step here is free: a bag in the back seat, a stuffed animal reminder, a phone alarm and a call-if-late agreement with child care.

How to choose an infant car seat (2026): fit, limits and recalls
Short answer: pick a rear-facing seat that fits your baby’s weight and height, fits your car, and that you can install tightly every time. NHTSA and AAP both say no single seat is safest and a higher price is not safer. Check NHTSA for recalls and get a free inspection.
guideCan babies sleep in car seats? Outside the car, travel systems and long drives (2026)
Short answer: dozing in a correctly installed car seat in a moving car is generally fine (AAP). Outside the car, no: infant car seats aren’t made for sleep, and a sleeping baby’s head can slump forward and narrow the airway. When you arrive, move your baby to a firm, flat sleep space on their back.
