Does heat lower IQ?
Heat can impair performance on attention and speeded tasks in some studies. That is a state effect, not proof your g just dropped a standard deviation forever.
Exam halls and heat waves?
Some education and economics papers link extreme heat to worse test outcomes. Methods and effect sizes vary. It is not a reason to invent a web-game IQ penalty.
Hydration overlap?
Thirst and heat often travel together. Cooling and water are ordinary comfort, not a clinical protocol from this site.
Are these games heat experiments?
No. Flanker-lite and reaction-time do not log your room temperature. Do not treat a slow run on a hot afternoon as a diagnosis.
What should I actually do?
If you can, take practice games in a comfortable room. That is common sense, not psychometric advice.
How should I practice here?
Try flanker-lite or go-no-go when you are cool enough to focus. Scores remain practice toys.

Test–Retest Reliability
If you take a test twice, the number often moves. Psychometrics calls the stable part reliability and the bouncing part error, practice, mood, sleep, or a different form. A web game score is especially noisy.
Test–Retest Reliability →What Is a Standard Score?
Raw scores (items correct, milliseconds) are not comparable across ages or tests. A standard score rescales them so that, in a reference sample, the mean and spread are fixed. This site does not convert game hits into that scale.
What Is a Standard Score? →IQ and Job Performance
Industrial-organizational research often finds that general mental ability predicts job performance better in more complex roles, with validity coefficients that are real but far from 1.0. This article is descriptive. It is not a recommendation to choose or reject a career from a web score.
IQ and Job Performance →Nutrition and Cognition
Brains run on ordinary metabolism. Skipping meals, dehydration, and extreme restriction can make attention feel worse in the short run. That is not the same as a supplement raising IQ, and this site does not sell or endorse pills.
Nutrition and Cognition →Smartphones and Attention
A phone buzz is a cue to switch. Task-switching and interruption costs are well known in cognitive psychology. That is not the same headline as “smartphones reduce IQ,” which oversells messy, correlational literatures.
