The most common mistake is the desire to immediately start working at full capacity. The brain needs time to adapt. Expect the first 1-3 days to be transitional.
Restore your sleep schedule.
An irregular sleep schedule is the main obstacle to concentration. Even the most engaging work won't help if your body continues to "think" it's still night. Gradually shift your bedtime and wake-up time by 20-30 minutes each day. An hour before bed, eliminate phone use and bright lights so your brain understands it's time to rest.

Diving straight into work can increase stress and cause resistance. It's better to dedicate the first 30-40 minutes to "warming up":
- familiarize yourself with plans
- complete a simple task
Move more.
After the holidays, your body may be relaxing, and a lack of physical activity decreases energy levels. A short walk, light exercise, or just stretching every 1-2 hours can significantly boost your concentration, sometimes even better than another cup of coffee.
Add enjoyable moments to your workdays.
Work after the holidays can seem dull if there are no joys in it. Plan small pleasures: a delicious lunch or your favorite music. Your brain will adapt to the work rhythm faster if it knows there's a reward ahead.
Returning to a work rhythm is not an instant process but a gradual one. Allow yourself a few days, be patient with fatigue, and don’t compare yourself to ideal standards. The rhythm will definitely return, especially if you take the right steps.
