Shafaqna English- A new study has found that wearing a cooling cap for 30 minutes a day may promote relaxation and improve mood in healthy young adults by increasing brain activity associated with calmness. Researchers at Pennsylvania State University examined the effects of selective head cooling in 24 college students over the course of one week. Participants either wore a cooling cap for 30 minutes each day while relaxing in a quiet room with ocean sounds or spent the same amount of time resting without the device. Despite the promising findings, the authors emphasize that the study does not demonstrate that head cooling can treat depression or anxiety. The researchers say larger, placebo-controlled studies involving more diverse populations are needed to determine whether daily head cooling can provide measurable mental health benefits and to better understand its effects on brain activity and emotional well-being.
