Yes, it can increase reaction time. Excessive heat can contribute to fatigue, sleepiness, irritability and loss of attention. There is no universal 24°C threshold above which every driver necessarily experiences those effects. Maintain suitable temperature and ventilation; if fatigue or sleepiness appears, stop in a permitted, safe place to rest.
