Depending on your sleep habits, you may need a loud alarm or a gentler option that awakens you gradually. Whether you’re a heavy or light sleeper, there’s an alarm clock that can wake you up reliably and effectively.
“Light sleepers may want as few distractions and artificial light as possible,” said Alex Dimitriu, MD, founder of Menlo Park Psychiatry and Sleep Medicine. “Deep sleepers may want an alarm that is loud or gradually loud, possibly with light or a sunrise simulator to facilitate waking up from a deep slumber.”
As a certified sleep science consultant and sleep researcher, I always test products to see if they can improve sleep quality. For this guide, the Insider Reviews team tested over 10 alarm clocks for three days each. We evaluated them on ease of use and reliability. There’s more information on our testing methods later in the guide.
