22 senses.

The traditional view is that humans have 5 basic senses (sight, hearing, touch, smell, taste), but modern science recognizes many more. Here's a concise list of 22 senses humans may possess:

1. Sight (vision)
2. Hearing (audition)
3. Touch (tactioception)
4. Smell (olfaction)
5. Taste (gustation)
6. Balance (equilibrioception)
7. Temperature (thermoception)
8. Pain (nociception)
9. Proprioception (body position)
10. Kinesthesia (movement)
11. Time (chronoception)
12. Hunger
13. Thirst
14. Fullness
15. Magnetoreception (controversial in humans)
16. Itching
17. Pressure
18. Tension
19. Stretch
20. Chemoreception (internal)
21. Equilibrioception (balance and acceleration)
22. Interoception (internal body sensations)

This list is not exhaustive, and there's ongoing debate about which sensations constitute distinct senses.
