If you are exhausted of many hot days in a row, take a walk in cool along a route with green tree branches roadside, maybe in rain, maybe in early morning, and look at the beauty of nature and feel the refreshing cool.
If it aren't so hot, you could try eating fried lax with it's liquid part on a piece of light coloured bread. Maybe fresh cucumber too.
If one in the summer or in the tropics gets a scratch from falling, insects or plants, maybe otherwise too, one could try putting tall grasses or tall grasses cut to pieces or lawn cut grasses or them with water on top of the would. If there are small insects or maybe bacteria too, they msybe prefer as natural environment the grasses instead of entering the body.
Some things which could soften life, if you have stomach ache because of some social problem, lufe situation or the like. Giving up the views that cause the ache, for example someone isn't so close to you or you do not have enough strenght to cobtinue on a certain studies. Go to the toilet. Drink some water. Wear loose comfortable clothes. Go to some nice place, often tidied to comfortable. Take a nice blanket to near you. Ventilate the room so that you have fresh air. Maybe eat a snack, try to listen to what would be right in questions of food. Comfortable subjects like nice music, nice professions, dream like places to move to and confortable enough near byvtoo. Listen to some music, put nasty papers etc away. Maybe take a nap or go out. Watch the beauty of nature.
