This study aims to determine the effectiveness of blue light in increasing alertness at night in tropical countries. Twelve healthy young males joined in this study. All participants were asked to do a monotonous activity that is reading activity. The experiment was a within-subject design with the independent variable is lighting condition (normal light and blue light) and duration of exposure (30 minutes and 60 minutes). Electroencephalography (EEG) signals were recorded continuously during the experiment. Alertness was measured based on theta, alpha, and beta activity. The result is the light condition not significantly affected the theta (F (1,11) = 0.608, ρ = 0.452), alpha (F (1,11) = 1.561, ρ = 0.237), and beta (F (1,11) = 0.608, ρ = 0.700) activity. This shows that blue light is not effective in increasing alertness at night in the tropical country both in short and long duration of exposure.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Authors thank RISTEKDIKTI for funding this research under the scheme of Hibah Kompetensi fiscal year 2018-2019.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1757-899X/722/1/012042[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
