Heat: what to do
Move to a cool place, take off unnecessary clothing, drink plenty of water or an isotonic sports drink, and cool the skin with cool water and a fan. You should start to cool down and feel better within 30 minutes. If you're struggling to treat it, or need advice, get help from NHS 111.

Call 999 (911 in the US): signs of heatstroke
If someone is still unwell after 30 minutes of resting in a cool place, being cooled and drinking fluids, or has a very high temperature, hot skin that isn't sweating, a fast heartbeat, fast breathing or shortness of breath, confusion and lack of coordination, a seizure or fit, or loses consciousness. Heatstroke is a medical emergency: while you wait, wrap them in a cool, wet sheet, or fan them or sponge them down with cold water.

In a class: leave the heat at the first sign
Leave the heat at once if you feel dizzy, get a headache or feel sick, and cool down straight away if it doesn't pass. In a survey of 157 hot yoga practitioners, just over half had had a problem, most often dizziness, light-headedness, nausea or dehydration, and case reports describe a cardiac arrest from heatstroke and a heart attack during hot classes.

After a hot job
Rest, drink and cool down before any exercise, and keep yoga at room temperature on shift days (our suggestion).

Sleep problems: see a GP
Changing your sleep habits hasn't helped, you've had trouble sleeping for months, or it's affecting your daily life in a way that makes it hard to cope.
Your breathing stops and starts while you sleep, you make gasping, snorting or choking noises, or you always feel very tired in the day. If someone has seen it happen, it can help to bring them with you.

Driving when sleepy
Don't drive when you feel sleepy. With confirmed sleep apnoea and excessive sleepiness, you must not drive until it's under control.

During yoga
A joint pain that is sharp, gets worse during a session, lingers into the next day or changes how you move is a reason to use an easier version, and to see a GP or physiotherapist if it keeps happening (the rule in our plans). Muscle soreness for a day or two after something new is normal. In a hot class, stop if you feel dizzy, sick or unwell; our hot yoga guide lists the signs of heat illness.
With glaucoma, or high blood pressure that isn't under control, skip headstands, shoulder stands and long head-down holds. With osteoporosis, swap deep forward folds for a flat-back hinge from the hips, and twist smoothly. In pregnancy, our yoga in pregnancy guide covers the changes. NCCIH advises beginners to avoid headstands, shoulder stands, the lotus position and forceful breathing.

Who should check first
The PAR-Q+ (Physical Activity Readiness Questionnaire for Everyone) asks about a heart condition or high blood pressure, chest pain, dizziness or losing consciousness, other long-term conditions and their medicines, a bone or joint problem that activity could make worse, and being told to exercise only under supervision. If you answer yes to any, check with your GP or a qualified exercise professional first. If you're over 45 and not used to hard exercise, ask a qualified exercise professional before the hardest sessions, and delay if you're ill.

Before you start
The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.
