There's one pre-summer intervention with more peer-reviewed support than almost anything else in sport science, and it's free.

Heat acclimation.

Two weeks of gradual, structured exposure to hot conditions before summer competition produces measurable physiological adaptations. Better cardiovascular efficiency, expanded plasma volume, more stable performance in heat. The science is settled. The ex*****on is where teams lose.

If you've actually run an acclimation block with your team, what did the schedule look like? Reply with the format that worked. Saving the good ones to share later.

Quick one for the coaches and ATs who are still on heat index.

Heat index measures the air. WBGT measures what your athletes are actually exposed to. Humidity, sun, wind, the whole picture. That's why the ACSM, NATA, NCAA, and NFHS all point to WBGT as the better signal.

Texas just adjusted UIL zones for 25-26. Florida runs hourly readings. California now mandates cooling zones at 80 WBGT and up. Policies are moving. The question is whether your practice plan moves with them.

Coaches and ATs, drop your district below. Are you on WBGT yet, or still pulling from heat index? Want to see where the spread actually is.

If you spent Memorial Day weekend between a tournament and a cookout, you're already in the part of the year that asks the most of your athlete.

The way you ramp into summer sports matter more than the workout that finally breaks your athlete.

Bodies adapt to heat through a process called acclimation. Most of the gains happen in the first week of consistent heat exposure. Full adaptation takes about two weeks. That's the published timeline from peer-reviewed thermoregulation research.

At home, that means gradual exposure beats a sudden start. Three short, hot sessions a week beats one long camp where everything cranks up at once.

Be honest with yourself. Is your athlete starting heat-ready this June, or are y'all going to find out on day one of summer practice? No judgment. Just asking, because if it's the second one, this week is when to change it.

At HeatSense we have a product to help monitor your athlete's real-time thermal response. Check out https://heatsense.com for more info.

The window before summer is the highest-leverage block on your calendar, and most teams under-utilize it.

Heat acclimation produces the largest physiological gains in the first 5 to 7 days of consistent exposure. Full adaptation lands at 10 to 14 days. Skip the ramp, and you're asking athletes to acclimate during competition, which is when the misses are most expensive.

Three moves worth making this week:
1. Build the gradual ramp into your spring-to-summer transition, not into camp week one.
2. Identify the athletes who've been mostly indoors. They're starting at zero.
3. Re-induct returning athletes who took a break. Acclimation decays in about 2 to 3 weeks without continued exposure, but rebuilds in roughly half the original time.

Coaches, real question. Does your program have a written heat acclimation plan, or is it tradition-based? Curious which programs have it on paper and which run on culture. No wrong answer.

Climate experts warn that one in four 2026 World Cup games could take place in very hot conditions. Whether you're attending soccer games or youth sports tournaments, grab a HeatSense sensor to monitor how you and your athlete's bodies respond to the summer heat.

Atheletic Directors, Coaches and Trainers - - The official Heat Safety Week message is hydrate, rest, check in. All of it works. None of it accounts for how different two athletes on the same field can be. Five things the research says about heat that the safety posters skip. Save this one for the August prep meeting.

One practice is dry and breezy. The other is humid with no shade. Same number on your weather app. Not the same practice.

The number you're looking at is air temperature. Coaches need a different one. It's called WBGT, wet bulb globe temperature, and it combines heat, humidity, sun, and wind into a single reading. It's the measurement the NCAA and most sports medicine groups use to assess practice risk.

Humid + sunny + no breeze is a different sport than dry and shaded, even at the same air temp.

Try this. Pull the air temp from your phone, then look up the WBGT for the same field at the same time. What's the difference in the readings? Drop it in the comments.

Next week brings the first real heat wave of the year across the eastern US, with the Mid-Atlantic and Carolinas catching the worst of it. Summer-level heat with stacked humidity, sticking through Tuesday and Wednesday before a cold front brings relief by Thursday.

This timing matters more than it looks.

The body adapts to heat through a process called acclimation. Most of the physiological adaptation happens in the first 5 to 7 days of consistent exposure.

Athletes who've been mostly indoors through April and early May are walking into a hot week unacclimated. That's the highest-risk window every summer, the gap between what the body is ready for and what the conditions are asking.

If your athlete has spring tournament games, end-of-season finals, or summer practice opening next week, three things to do this weekend:

Front-load hydration starting Saturday. Don't wait for Monday morning.

Ask the coach what the heat ramp looks like next week. If practice plans match the forecast, you'll feel it in the planning. If they don't, that's a conversation worth having.

Talk to your athlete about the difference between feeling thirsty and being hydrated. Thirst lags. By the time it shows up, the body has been running short for a while.

At the field last night it was still in the 90s at 6 p.m. In May. My athlete kept saying he was fine. They always say they're fine.

Nobody told me until I started looking that by the time an athlete feels off in the heat, the body has been working overtime for a while. The brain, the muscles, the focus. The heat hits all of it before you'd guess from the sideline.

Coaches do everything they can, but they're watching 30 athletes at once. Nobody can see what's happening inside a body just by looking.

That's the part we're trying to share with other sports parents now. Not to create panic, just to let parents see the data and know what's going on. That's why we built HeatSense.

Sports parents, be honest. When your athlete says 'I'm fine' on a 90-degree day, do you believe them, or are you the one quietly tracking every minute on the field? No wrong answer. Curious where everyone lands.

“No one tells you this as a sports parent, but the heat affects your kids way before they look like they’re struggling.”

Parents - it's time to check out HeatSense before the summer heat is here to stay.
