Mental health and sleep difficulties can interact and worsen one other. People with anxiety, depression, bipolar disorder, and schizophrenia are more prone to have insomnia, hypersomnia, nightmares, and sleep apnea. Chronic sleep deprivation or poor sleep quality may affect cognitive performance, emotional control, and stress response systems, exacerbating mental health issues. Modalert 200, which contains modafinil, may improve alertness and cognitive performance by reducing daytime drowsiness caused by sleep problems. For general health and symptom management, treating underlying mental health concerns and adopting holistic treatment techniques that promote sleep hygiene and mental well-being are essential.
