It is important to note that IQ is largely determined by genetics, but there are some things you can do to improve your cognitive abilities and overall mental performance:

1. Exercise regularly - physical activity increases blood flow to the brain, which can help with cognitive function.

2. Challenge your mind - engage in mentally stimulating activities such as puzzles, playing chess, or learning a new language.

3. Get enough sleep - lack of sleep can negatively impact cognitive abilities.

4. Eat a healthy diet - a well-balanced diet that includes brain-boosting foods such as berries, fish, and nuts can help improve cognitive function.

5. Reduce stress - stress can negatively impact cognitive function, so finding ways to manage stress such as meditation or yoga can help.

6. Keep learning - continuous learning and seeking new experiences can stimulate the brain and improve cognitive function over time.

Remember that while these practices may help improve cognitive function, they may not necessarily increase your IQ.
