Training in Heat and Bad Air: What the Official Advice Says

“Even healthy persons can be affected when they exercise outdoors.” That line is from a presentation on India’s National Air Quality Index, prepared by the Indian Institute of Technology Kanpur and sponsored by the Central Pollution Control Board.

A young athlete in India trains through two conditions most coaching manuals were not written for: summer afternoons above 40°C and winter mornings of thick smog. Families mostly decide by habit. There is official guidance for both, and it is short enough to remember.

Heat

The National Disaster Management Authority (NDMA) publishes its heatwave advice as a set of posters. Two of the titles on its heatwave page speak directly to sport: “Avoid strenuous activities when outside in the afternoon” and “Protect your children from heat wave”.

For training, that turns into a simple rule: in a heatwave, hard outdoor sessions belong in the early morning or the evening, never in the afternoon.

Three practical points follow from the same advice.

Timing beats toughness. A coach who schedules a hard session at 2pm in May is not building character. Ask for the session to move.

Water is part of the session. The Sports Authority of India’s own testing instructions for children tell coaches to make sure participants drink enough water during testing, as The fitness tests coaches use to spot a child notes. The same standard applies on any hot day.

Check the warning, not the sky. Heatwave warnings are issued officially. On a day with a warning, treat the afternoon as closed for hard outdoor work.

We read the poster titles on the NDMA page, not the posters themselves, which are large image files. Open them for the full list of dos and don’ts.

Bad air

The same index presentation explains why children are a special case. It lists the very young as at risk for two reasons: their lungs are not fully developed, and they breathe faster, taking in more air for their body weight. Exercise raises breathing further.

India’s index has six bands. The presentation gives a possible health impact for each:

Band	Possible health impact, as stated
Good	Minimal impact
Satisfactory	Minor breathing discomfort to sensitive people
Moderate	Breathing discomfort to people with lung disease such as asthma, and discomfort to people with heart disease, children and older adults
Poor	Breathing discomfort to people on prolonged exposure and discomfort to people with heart disease with short exposure
Very poor	Respiratory illness to the people on prolonged exposure; effect may be more pronounced in people with lung and heart diseases
Severe	Respiratory effects even on healthy people and serious health impacts on people with lung or heart diseases

Notice where children first appear by name: at Moderate, the third band, not the fifth.

The presentation does not set training rules, and we have not read an official Indian document that tells sports coaches at which band to stop a session. So what follows is our reading, not a rule: from Poor upward, shorten or move hard outdoor sessions for children, and at Very poor or Severe, take the session indoors or make it a light one.

A child with asthma needs a plan from their doctor, not from an article.

What a lost session costs

Less than families fear. A study of adolescent athletes found that three weeks without strength training did not reduce their strength or performance, as Keeping fitness through exam months explains. One afternoon moved to the evening, or one smoggy morning spent on stretching and skill work indoors, costs nothing that matters.

That is the right way to weigh it. The cost of skipping is small and known. The cost of training hard through a heatwave is not.

The monsoon

We did not find an official source on training in the monsoon and will not invent one. Two points are common sense: wet ground changes footing, and open grounds are no place to be in a thunderstorm.
