We all face sleep problems at one point or another. You could be cosy as you like on your divan bed, couch or even your floor, but getting to sleep is often another matter. Deborah Rozman, a sleep specialist writing for Care2, has compiled three top tips to help those struggling against the pains of insomnia, focusing heavily on the heart's role in proceedings. The first tip regards heart rate. The expert explained that worry, stress, anxiousness and overstimulation leads to a "more chaotic" heart rhythm, so working on positive feelings before bedtime will help your body put itself into sleep mode a lot easier, while also helping you wake up more refreshed. Breathing and its effects on the heart are also worth some thought. If you gently breathe to create a sense of calm, using memories of appreciation, love or gratitude, you can "activate coherent heart rhythms and release beneficial hormones to reduce stress" and help yourself on your way to better sleep. Finally, Professor Rozman said that if you have an argument before bedtime, sort it out before you sleep. Without this approach, you could have a few sleep problems and only make your mood - and the situation - worse in the morning.
