Short naps have shown to increase the ability to store and recall information, and improve vigour, alertness and cognitive performance. Current studies also suggest that brief daytime napping might have a positive effect on anxiety and depression.

Power naps are frequently recommended as a way to improve cognition, focus and reduce tiredness. But what are the physiological effects on the body, and why can longer nap times leave us more groggy and tired than before?

Studies have shown that consistent and good sleep, where we sleep more than 7.5 hours per night has a positive impact on healthy blood pressure, cardiovascular health, libido and fertility, and protects from diabetes and mental health issues.

We are the only species that can intentionally deprive themselves of sleep. Since sleep makes up about one-quarter to one-third of our life, it is safe to say that important processes are happening in our body during that time. Good sleep keeps us healthy and functioning well and allows our body and brain to repair, restore, and be re-energised.

Many of us have been brought up with a go-getter attitude, which means that the first thing we compromise on is our sleep. This results not only in less sleep, but also shortening or skipping through different sleep stages. Today, the science and research behind sleep explains the importance of each sleep stage and the impact on our longevity and prevention of diseases.

Getting a good night of sleep is not always easy, especially in today’s world of technology, blue light, stress and family commitments. Many of us spend 6-8 hours in bed, but we still don’t feel refreshed in the morning, and we don’t know the reason why. Perhaps, we might be struggling with sleep apnea.
