Step-by-step explanation:
The student has asked for the best recommendation for a client who is experiencing difficulty falling asleep. Among the given options, the correct suggesting would be: b) Take a warm bath to relax before going to bed. This is because warm baths can help to relax the muscles, reduce tension, and signal the body that it's time to wind down in preparation for sleep.
Other tips for better sleep hygiene include keeping the bedroom temperature cool, avoiding stimulants such as caffeine and electronics before bedtime, and adhering to a consistent sleep schedule. The use of smartphones and other electronics in bed should be avoided as they emit blue light, which can interfere with the body's production of the neurotransmitter that promotes sleep.
Additionally, maintaining a variable sleep schedule is contrary to good sleep practices; a fixed routine helps to regulate the body's internal clock, leading to improved sleep quality over time.
