The type of alarm you hear in the morning can affect your day

If your alarm wakes you up suddenly, and you feel groggy for hours, you are experiencing sleep inertia. While the main cause is lack of sleep, the sound of your alarm can play a big role too. In a new study published in the Journal of Sleep Disorders & Therapy, researchers split participants into two groups: one using traditional alarm sounds and one using melodic tunes. After they woke up, they performed a series of tasks. They found that the group that woke up to melodic alarms showed better response times and higher accuracy. Since loud, non-melody alarms have been linked to high blood pressure, heart rate, and headaches, you might consider changing your ringtone settings to a pleasant tune instead.
