Write the heat plan while the day is still easy: water on a schedule, shade you name in advance, and a stop that does not require a speech.
The plan is written while the day is still easy. A hot week is a bad time to invent it.
A heat plan written during the heat is already late. I am writing this on 15 June 2026, ahead of the hot weeks, because that is the only week the plan is cheap. Once the rooms are hot and the head is slow, people improvise. They skip water because they are busy. They keep the hard task in the hottest hour because the calendar said so. They treat the stop as a failure of character. Character is not a cooling system.
This is for any household in any warm region. It is not a dispatch from a disaster, and it is not a claim about one town. Heat is ordinary until it is not. The World Health Organization's page on heat and health says the harm is largely preventable, and that heatstroke is a medical emergency. Preventable means the actions exist before the alert. Emergency means you do not spend the emergency inventing the actions.
I use the same order I use for a launch, which is why “5 questions before launching a business” sits beside a launch even though one is a firm and one is a body. You decide the constraints before the day that will test them. For heat, the constraints are three words: water, shade, and a stop. Write them down while you are still comfortable. “Training for people who sit all day” is the cooler-month cousin. Heat is the hot-month plan. They are not the same plan, and you want both before you need either.
Thirst is a late signal. By the time you feel dramatic thirst, you have already spent part of the morning under-hydrated, and the decisions of that morning were worse than you think. The WHO's practical line is to drink water regularly, on the order of a cup an hour and at least two to three litres across the day, unless a clinician has given you a different limit. If you have a kidney, heart, or fluid restriction, you follow the clinician, not a blog. For everyone else, the plan is a bottle you can see, filled before the work starts, and a time you drink whether the meeting is interesting or not.
Write the bottle into the morning the way you write a key into a bag. One bottle at the desk. One bottle if you leave the building. If you employ people who work outside, or in a kitchen, or in a vehicle, the water is part of the job, not a personal virtue. “Doing business with family and friends” is about the messy overlap of care and work. Heat is one of the places that overlap gets physical. The person you love, and the person you pay, both need the bottle. Affection does not replace it. A wage does not replace it either. You put the water where the work is.
Alcohol and a heroic coffee habit are not the plan. They are how people pretend they have a plan. I am not opening a lecture on drinks. I am saying the liquid you counted, in the cool hour, is water. If the day includes a long meal, the water still happens. A feast is not a cooling strategy.
Shade is not a feeling. It is a room, a side of a street, a tree you have already chosen, or the simple act of staying indoors through the worst hours. The WHO tells the public to avoid strenuous activity in the hottest part of the day, to stay in the shade, and to spend a stretch of the day in a cool place. Perceived temperature in the sun runs well above the air temperature. People lose that fact because the errand feels short. Short errands are how a hot day injures a person who thought they were only stepping out.
Name the place on paper. In a house, which room stays coolest, and who has the right to use it, including the person who usually gives it up. In a workplace, where the break happens, and whether that place has moving air. The WHO notes that fans help when the air is under 40 degrees Celsius, and that above that they heat the body. If you are in a region that reaches those numbers, the plan cannot be “a fan and toughness.” It has to be a cooler room, a changed hour, or a stop. Ready.gov's heat page is the United States preparedness sheet. Read it before the week, not during the headache.
Clothing is part of shade. Light cloth, loose, and a way to wet the skin if you are overheating: a shower, a damp cloth, wet cloth rather than a dry cover. The WHO is specific about infants. Never leave a child or an animal in a parked vehicle for any amount of time. Never cover a stroller with a dry fabric, which traps heat. Those two lines are the plan for anyone who moves a child through a hot day. Write them where the person who does the school run will see them in June, not in August when everyone is already irritable.
Water and shade still fail if the work is not allowed to stop. I have run days, and I have watched other people run days, where the schedule was written in a cool office and then obeyed in the sun as if the sun were a suggestion. The stop has to be decided by a condition, not by guilt. If someone is confused, stops sweating in extreme heat, has a pounding headache, vomits, or cannot cool down, you are no longer in a productivity conversation. The NHS page on heat exhaustion and heatstroke is there so you can learn the difference before you need it. Heatstroke is the emergency. You do not negotiate with it for the sake of a deadline.
For ordinary heat, the stop is earlier and duller. Move the heavy task out of the hottest hours. Shorten the outdoor meeting. Let a person leave the floor without making a speech about commitment. “Avoid yes-men” belongs beside a hot workplace, because heat produces false agreement. People nod so they can sit down. A leader who wants the truth has to make the stop easy to say.
