2. Outdoor Adventures – park hikes, bike rides, or weekend camping trips.
3. Cooking Together – choose a new healthy recipe, divide prep tasks, and enjoy the meal as a team.

• Digital‑Detox Challenge
• Commit to a 24‑hour “no messenger” day each month; track mood improvements and note any heightened sense of presence with family members.

Organizational Hacks to Reduce Screen Time

• Inbox Zero for Messenger
• Set a daily “clear chats” alarm at 18:00 h; archive or delete non‑essential conversations to prevent clutter.

• Priority Labels
• Use Messenger’s “Starred” or “Crucial” tags only for urgent matters; everything else can be addressed during a dedicated 15‑minute “check‑in” window.

• Workspace Redesign
• Keep phone and messenger‑enabled devices out of arm’s reach; employ a “dock‑only” station for essential work tools, reducing impulse checks.

• automation Tools
• Activate “Do Not Disturb” during focused work blocks; schedule automatic replies that inform contacts of your offline hours.
