Question

Precaution taken while playing on ground to protect from sunstroke

Answer 1

cover the head with a cap

Answer 2

When you play, you tend to forget the heat.  It is better to wear clothes which allow air to circulate in your body.  Do not wear tight clothes.  Apply sunscreen lotion before going out.  Drink lots of water during the play.  Do not drink aerated drinks, instead you can take fresh fruit juice.  You can carry a lemon in your pocket and squeeze some into your mouth when you are feeling too hot.  You should also wear a hat and a sunglass to protect you from heat.
