What are the best daily habits to reduce stress quickly?

What are the best daily habits to reduce stress quickly? I’m curious about which simple routines can help calm the mind and body within a short time during a busy day. Do habits like deep breathing, regular exercise, or taking short breaks actually reduce stress instantly? I also wonder if things like maintaining a healthy diet or getting enough sleep play a big role in daily stress levels. What practical habits can someone follow consistently to feel more relaxed and in control every day?
