Your sentence is a bit open-ended, so the “consequences” depend on what you meant by sleeping with someone.
If you mean having sexual intercourse, possible outcomes include:
- Pregnancy (if protection isn’t used or fails)
- STIs (sexually transmitted infections) like chlamydia, gonorrhea, HIV, etc., especially without protection
- Emotional effects, which can range from positive bonding to regret or confusion depending on the situation and expectations
- Sleep/energy changes (some people feel relaxed afterward; others may feel tired or disrupted sleep patterns)
- Relationship impacts, if expectations between partners aren’t aligned
If you meant literally sharing a bed with someone (no sex involved), the “consequences” are usually much simpler:
- Possible sleep disturbance (snoring, movement, different sleep schedules)
- Comfort or warmth benefits
- Emotional comfort or bonding, depending on the relationship
If you want, tell me what angle you were aiming for (health, relationship advice, or something else), and I can go deeper in that direction.
