We all have times when we have a lot of work pressure, which can put our health at risk. Taking time to relax will energize you for the next busy day.
After a hectic day you can take a bath, also you can have a cup of hot coffee. You should practice deep breathing exercises. You can Cook your favorite food. Do something that you really enjoy. You can Watch your favorite TV show... etc.
All these activities will definitely help to relax.
