How do I stop stress from affecting my sleep quality?

The most effective approach is to create a clear boundary between your stress and your sleep environment. About an hour before bed, stop checking emails or anything work-related, and do a brief "brain dump" by writing down tomorrow's tasks so your mind stops rehearsing them. This offloads mental chatter onto paper. Physically, keep your room cool and dark, and try slow diaphragmatic breathing when you lie down, inhaling for 4 counts and exhaling for 6-8, which activates your parasympathetic nervous system. Consistency matters most, so wake at the same time daily regardless of how you slept. Over time this rebuilds your sleep drive and reduces the anxiety around falling asleep itself.
