Sleep and recovery: start with regular timing
Sleep deserves a place alongside exercise and meals. A first change can be a more predictable bedtime and wake-up time.

Heat changes exercise conditions. Your result on a cool day is not a compulsory target in midday heat.
Choose a cooler time, shade and an easier session. Bring water and have a way to stop if you feel unwell.
Stop and move somewhere cool for dizziness, weakness or nausea. Confusion, fainting or severe deterioration require emergency help: call 112 in Bulgaria and the EU.
