negative effects » negative affect (Expand search)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decrease strain decrease ) OR ( decrease akt decrease negative effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease strain decrease ) OR ( decrease akt decrease negative effects ))*.
