There are situations in which cell phones can pose a hazard to your health.
Most of these health problems come about because of inattention caused by cell phone use contributing to accidents, or from repetitive strain conditions, such as “tech neck“. Concerns about possible harm due to exposure to electromagnetic fields have also been raised.
Is there any health hazard caused by sleeping with your phone near head?
Apart from discomfort if you lie on it, or disrupted sleep if it rings, no, at least as far as is known right now. Concerns about the possible effects of electomagnetic fields have not been substantiated conclusively through research so far.
That said, there is a growing body of research suggesting electromagnetic exposure from a variety of sources is a contributor to the development of some illnesses, including cancer, and the World Health Organization has issued a fact sheet advising people that there is a basis for concern which is being more rigorously investigated.
