Two-a-day football practices return across Texas this August, but the rules covering them changed this year. Starting August 1, 2026, the University Interscholastic League made its wet bulb globe temperature heat stress plan mandatory for every member school, a policy born from years of heat-related injuries on Texas practice fields. Less visible, but just as relevant to athlete safety, is what teenagers are putting into their bodies before those practices: prescription stimulants, energy drinks, and pre-workout supplements that change how the body handles extreme heat.
For two years, UIL member schools followed a recommended heat stress plan based on wet bulb globe temperature, a measurement that accounts for humidity and sun exposure, not just air temperature. The Medical Advisory Committee reviewed how that recommended plan worked and asked the Legislative Council to make it mandatory starting this season. The new rules are specific. When the reading falls between 90.1 and 92.0 degrees, football practice is limited to one hour outdoors, players cannot wear protective equipment, and conditioning drills are not allowed at all. Above that threshold, practice moves indoors or stops.
The mandate exists because heat illness in young athletes is preventable, and Texas coaches have watched it happen anyway for decades. What the rule does not account for is what an individual athlete has consumed before stepping onto the field.
It would be easy to assume nonmedical stimulant misuse among teenagers is rising along with pressure to perform in youth sports. The data says the opposite. A 2025 JAMA study tracking Monitoring the Future survey data found that nonmedical use of prescription stimulants among adolescents hit its lowest recorded level in 2023, with current use at just over 1 percent nationally. Legitimate medical use of ADHD medication, by contrast, has climbed modestly over the same period.
That does not mean the risk has disappeared. Older teenagers, specifically those in 10th and 12th grade, still misuse stimulants at roughly double the rate of 8th graders, and prescribed stimulant use is now common enough that a meaningful share of any given football roster is legitimately taking Adderall, Vyvanse, or a similar medication under a doctor's supervision. Neither group is doing anything wrong. Both face the same physiological wildcard once August heat enters the picture.

Stimulant medications, whether prescribed or diverted from a classmate, raise heart rate and core body temperature and can mask the early sensation of overheating. A teenager on a stimulant may genuinely not feel as hot as their body actually is, which delays the moment they ask for a water break or tell a coach something feels wrong.
Energy drinks compound the problem in a way most families do not think about until it becomes a headline. The CDC has documented energy drink related emergency room visits among adolescents involving irregular heartbeat and other cardiac symptoms, and case reports of sudden cardiac events tied to energy drink consumption tend to involve some degree of physical exertion. The National Federation of State High School Associations has recommended against energy drink use for hydration among young athletes for exactly this reason. A drink marketed for focus and energy is, physiologically, a caffeine and stimulant dose layered on top of whatever else is in an athlete's system, taken right before hours of exertion in August heat.

Heat illness combined with stimulant use does not always look like the textbook version. Watch for an athlete who seems unusually confident about pushing through practice despite visible signs of distress, a racing pulse that does not settle during a mandated rest break, or confusion and irritability that seems out of character. These can be signs of heat exhaustion, an adverse reaction to a stimulant, or both at once, and the right response is the same regardless of the cause: get the athlete out of the heat, cool them down, and get medical attention if symptoms do not improve quickly.
Most teenagers taking a stimulant before practice are not trying to cheat or get high. Some have a legitimate prescription and have not connected it to heat risk. Others are managing undiagnosed anxiety, sleep deprivation, or the pressure to make varsity, and a friend's leftover Adderall feels like a reasonable solution to a real problem. Approaching that conversation with curiosity instead of accusation, asking what is actually driving the exhaustion or the need for an edge, tends to get further than a lecture about drug misuse. Families who want a deeper look at how this pressure shows up at the next stage of life can also read our earlier piece on Adderall misuse among college students.
When stimulant misuse is connected to an undiagnosed mental health condition, treating one without addressing the other rarely holds. More Than Rehab, a LegitScript-certified provider, offers dual diagnosis care that treats substance use and co-occurring mental health conditions together, built around a social model of recovery rather than isolation.
Why did Texas high school heat rules change for the 2026 season?
The University Interscholastic League made its wet bulb globe temperature heat stress plan mandatory starting August 1, 2026, after two years of voluntary use by member schools. The rules set specific limits on outdoor practice time and equipment based on real-time heat and humidity readings.
Is prescription stimulant misuse among teens increasing?
No. National survey data through 2023 shows nonmedical use of prescription stimulants among adolescents has fallen to its lowest recorded level. Legitimate medical use of ADHD medication has risen modestly over the same period.
Can energy drinks be dangerous for student athletes?
Yes, particularly during intense exercise in heat. Energy drinks combine high caffeine content with other stimulants, and case reports have linked their use during physical exertion to cardiac symptoms including irregular heartbeat.
What should I do if my teen seems overheated and unusually wired at the same time?
Get them out of the heat immediately, help them cool down, and seek medical attention if symptoms such as confusion, rapid heartbeat, or nausea do not improve quickly. Do not wait to see if it passes on its own.
Texas has taken a real step toward protecting young athletes from heat illness this season. That protection works best when it accounts for the whole picture, not just the thermometer. If stimulant use, prescribed or otherwise, has become part of how your teenager copes with the pressure of Texas sports culture, that conversation is worth having before it becomes a bigger problem.
