No, they don’t.We all need between seven and a half and eight and a half hours a night. However, men do have longer sleep-cycles, which make them morę difficult to wake up and morę likely not to hear a baby crying.

Not if you take them occasionally. The problem is that the morę you take them, the morę tolerant your body becomes and the less effective they are, so if you take them regularly you end up needing to take morę for them to have an effect, and this can be bad for your body.

The real test is daytime sleepiness. If you have to struggle to stay awake during the day or feel a constant longing for your bed, thęn you are probably sleep-deprived and need morę hours at night.
